finishing concrete surfaces.
If used correctly, they will provide an effective and safe
means of finishing and meet the appropriate performance
standards.
It is essential that the operator of the machine is adequately trained in its safe operation, be authorized to
operate it, and have sufficient knowledge of the machine
to ensure that it is in full working order, before being put
to use.

Health & Safety
WARNING
Safety Precautions
• Before using this equipment, study the entire owner's manual
to become familiar with its operation. Do not allow untrained or unauthorized personnel, especially children, to
operate this equipment. Use only factory authorized parts
for service.
• When warning decals are destroyed or missing, contact the
Manufacturer immediately at 1-800-888-9926 for replacement. For the safety of yourself and others, it is imperative
that the following rules are observed. Failure to do so may
result in serious injury or death.
USE COMMON SENSE WHEN HANDLING FUELS
• Transport and handle fuel only when contained in approved
safety containers.
• Do not smoke when refueling the engine or during any other
fuel handling operation.
• Do not refuel with the engine running or while hot.
• If fuel is spilled during refueling, wipe it off from the engine immediately and discard the rag in a safe place. Do
not operate the mixer if fuel or oil leaks exist-repair immediately.
• Never operate this equipment in an explosive atmosphere.
• Never perform any work on the trowel while it is running.
Before working on it, stop the engine and disconnect the
spark plug wire to prevent accidental starting.
• Do not operate this trowel without all guards in place. Keep
hands, feet, clothing and jewelry away from the trowel
blades and all moving parts. Rotating and moving parts
will cause serious injury if contacted during operation.
• Do not allow anyone to stand or lean on the trowel during
operation.
- 12 -
Health & Safety
Safety Precautions
• Keep the patented Dyna-Clutch safety system in adjustment
and good operating condition at all times. Do not operate
the trowel if it does not work properly. Out of control Trowels can cause serious personal injury and damage to fresh
concrete surfaces. The Dyna-Clutch system will automatically stop the trowel if the operator loses control of it during operation.
• Make sure the Dyna-Clutch is disengaged (lever in the down
position) before starting the trowel. Keep one hand firmly
on the handle while starting and do not let go of the handle
during operation.
• Avoid contact with hot exhaust systems and engine parts.
• Allow engine to cool before performing any repairs or
service.
• Ear protection required when operating this equipment.
• Never operate any gas powered equipment in a poorly
ventilated or enclosed area.
• Avoid prolonged breathing of exhaust gases.

Introduction
Location and Use of Controls
LOCATION AND USE OF CONTROLS
Before operating this trowel, it is important to
familiarize yourself, and any other personnel
who will be using it, with the location and
proper use of the controls to insure safe and
efficient operation:
A - HANDLE ADJUSTMENT KNOB - to
adjust the handle for maximum operator
comfort and control, simply turn the knob-one-quarter turn maximum counterclockwise to loosen, move handle to desired
position and tighten knob to lock handle in
place.
B - THROTTLE CONTROL - this is a pushpull type throttle control which can be
locked at any desired blade speed from 50 to
130 RPM, to meet varying job conditions.
To use, simply push or pull the throttle
control to obtain the desired blade speed.
To lock the throttle at the speed, turn the
control clockwise. To unlock the throttle for
further adjustments, turn the control counter
clockwise approximately 1/4 turn.
- 14 -
C - DYNA-CLUTCH LEVER - this is a
patented feature which acts as a safety
device to stop the trowel from spinning out
of control if the operator lets go of the
handle. It also allows the operator to control
the engagement and disengagement of the
trowel blades independent of engine speed.
To use, simply move the lever all the way up
to the RUN position to engage the trowel
blades. To stop the blades from turning,
push the lever all the way down to STOP
position. In the event that the operator lets
go of the handle while the blades are
turning, the centrifugal force from the swing
of the handle will throw the Dyna-Clutch
lever to the STOP position. This prevents
the trowel from spinning out of control and
causing injury to personnel or damage to the
trowel and fresh concrete. Since the DynaClutch system disengages the blades from
the engine, rather than shutting down the
engine to stop the blades, time is saved in
getting the trowel operating again. The
operator simply moves the Dyna-Clutch
lever to RUN position instead of having to
restart the engine and readjust engine speed.
D - TILT ADJUSTMENT KNOB - adjusts the
angle of the blades for different curing
stages and conditions of the concrete.
Turning the knob clockwise increases the
angle of the blades to the concrete. Turning
the knob counterclockwise flattens or
decreases the angle of the blades.
Adjust Tilt Knob Lock
Nut/Linkage Rod
Introduction
TO ADJUST TILT KNOB LOCK NUT --The
tilt lock nut is located on the tilt rod assembly.
Using the lifteye, raise the trowel with an overhead
crane. Back off tilt knob until there is enough
cable slack to access the tilt lock nut. For more
tilt, loosen lock nut set screw and turn lock nut
towards tilt knob, 1 turn, and lock set screw.
Crank knob to full tilt position and check clearance
between the tilt lever and gearcase for 1/64"
(paper thickness). Repeat adjustment if required.
NOTE: Cables may stretch over time and may
need to be replaced if full tilt is no longer
obtainable.
TO ADJUST ProPitch™ LINKAGE
Rod--The linkage rod is fastened to a yoke end
and a swivel by two nuts. To adjust follow the
steps listed below.
1. Using the lifteye, raise the trowel using an
overhead crane.
2. The lower end of the linkage rod is connected
to a yoke and held in place with two (2) nuts.
Loosen the nut on the upper end of the linkage
rod to allow slack in the tilt cable when the
ProPitch handle is in full tilt position.
4. With handle in full tilt position, adjust the nut
on the backside of swivel at the upper end of
linkage rod until the proper gap is achieved
between the tilt lever and the gearcase-approximately 1/64 inch.
5. Tighten nut on the outside of swivel to lock
linkage rod into position.
6. Repeat adjustment if required.
NOTE: Cables may stretch over time and
may need to be replaced if full tilt is no
longer obtainable. Refer to Service and Parts
Manual for full diagram and parts breakdown.

Maintenance
Maintenance, Lube & Adjustment
MAINTENANCE, LUBRICATION
AND ADJUSTMENT
These oil requirements are general guidelines
only, for specific requirements consult the
ENGINE MANUAL included with the trowel.
To get long and trouble free service from your
new CF Power Trowel, it is essential to perform
periodic maintenance on engine and machine
mechanisms. Follow the guidelines listed
below:
B. TROWEL GEARCASE
LUBRICATION
A. ENGINE CRANKCASE
Daily--check oil level in engine. Engine warranty is VOID if it is run without oil. Add oil as
required to keep crankcase full. Engine oil
should be changed every 250 hours of operation,
or once a year, whichever comes first.
Daily--check oil level in gearcase. Trowel
warranty is VOID if is run without oil. Oil level
should fill the sight plug, located on the right
side of the gearcase, when the trowel is at rest
on a level surface. Add oil as required to keep
oil level at correct height. Gearcase oil should
be changed every 250 hours of operation, or
once a year, whichever comes first. Use 90
weight oil when changing or adding oil to the
gearcase.
C. ARM BEARING
Monthly--grease arm bearing through the grease
fittings in the spider. There are (3) fittings on
(3) arm trowels and (4) fittings on (4) arm
trowels. Pump grease into each fitting until
clean grease comes out of spider at either end,
thoroughly clean excess grease off from spider
when all arms have been greased. Use any
grade #1 lithium base grease.
Oil requirements are as follows:
Temperatures above 40°F (4°C) - SAE 30
Temperatures below 40°F (4°C) - SAE 5W20
D. THRUST BEARING
Weekly--grease with any grade 1 Lithium based
grease to purge out any dirt or water. Wipe off
excess grease.
Yearly--for bearing lubrication remove
thrust bearing and clean thoroughly.
Inspect for damage and replace if necessary or repack with any grade #1
lithium-based grease and reinstall.

Cleaning
E. DYNA-CLUTCH LEVER CABLE
CLEANING
Yearly--lubricate the DYNA-CLUTCH lever
cable with any good control cable lubricant.
Spray the lubricant down the end of the cable
housing from inside of the Dyna-Clutch housing, wipe off excess lubricant from the ends of
the cable.
For consistent performance and long life,
thoroughly clean the trowel at end of daily
operation. Spray the blades and lower end of
the trowel with water to clean off accumulated
concrete. Wipe dirt and concrete from engine
with a damp rag. Thoroughly dry trowel and
apply a light coat of WD-40 or other light oil to
the blades to prevent rust.
F. BLADE TILT MECHANISM
Yearly--lubricate the tilt knob threads and
bearings with a few drops of light oil. Screw the
tilt adjustment knob out just far enough to gain
access to the threads and bearing. DO NOT
screw the knob completely out of the handle.
Hanging the trowel from its lifteye facilitates
this operation.
HARDWARE AND TORQUE CHART
Periodically inspect all hardware on the trowel
and engine. Loose hardware can contribute to
broken parts and early component failure. Use
the torque chart below as a general guideline
and keep all hardware tight.

Dyna-Clutch Adjustment
DYNA-CLUTCH ADJUSTMENT
The Dyna-Clutch is an important safety device
which prevents the trowel from spinning out of
control in the event the operator lets go of the
handle during operation. When properly adjusted,
it will disengage the trowel blades from the engine within the first 3/4 revolution of the handle.
The handle may "coast" another 1/2 to 3/4 revolution, but it is no longer swinging under power.
This will prevent injury to personnel and damage
to the trowel and fresh concrete surfaces.
6. If finer adjustments are required, loosen
the (2) lock nuts slightly. By turning both
lock nuts clockwise, tension on the cable
and spring will be increased. Turning both
lock nuts counter clockwise will decrease
tension.
B
The Dyna-Clutch must be adjusted periodically
to compensate for belt wear and stretch, and also
whenever the belt is changed.
PRELIMINARY ADJUSTMENT - to adjust
Dyna-Clutch, proceed as follows:
7. Tighten the (2) lock nuts against the cable
housing bracket after making any
adjustments.
1. Move the Dyna-Clutch control lever on the
handle to the STOP position.
8. As a preliminary test, start the trowel,
engage the Dyna-Clutch and run for a few
moments then move the Dyna-Clutch lever
to the STOP position. Observe the blades,
watching for any sign of continued
rotation. If the blades do not want to stop,
there is too much tension on the cable and
spring. Shut down the engine and decrease
the amount of tension as per steps (6) and
(7) above, to allow the Dyna-Clutch to
disengage completely.
2. Loosen (2) lock nuts (A) and spin them out
of the way toward either end of the cable
housing adjustment barrel (B).
3. Grasping the cable housing with one hand,
lightly pull it away from the cable housing
bracket (E) to apply tension to the control
cable (C). Proper adjustment is when the
control cable is taut but there is no tension
on the spring (D).
Also make sure that there is still enough
tension on the cable and spring to prevent
these parts from coming unhooked during
operation. If the tendency for the blades to
rotate when the Dyna-Clutch is disengaged
cannot be adjusted out of the system
without taking all tension off the cable and
spring, carefully inspect the drive belt and
Dyna-Clutch system for wear or damage.
Make sure all parts are operating freely.
Repair as necessary to insure proper
operation of the Dyna-Clutch system.
4. Spin the (2) lock nuts against the cable
housing bracket with the other hand and
tighten them against the bracket to lock the
cable in adjustment.
5. Check the tension on the control cable and
spring. If there is too much tension on the
control cable and spring, the Dyna-Clutch
will not disengage completely. If there is
not enough tension, the spring and cable
may disconnect from the Dyna-Clutch,
leaving the system inoperative.

Maintenance
Final Testing and Adjustment
FINAL TESTING AND ADJUSTMENT - to
make sure the Dyna-Clutch is properly adjusted,
the trowel must be tested as follows before it is
allowed back in service.
3. Start the trowel, move the Dyna-Clutch
lever to the RUN position to engage the
blades and adjust engine speed if
necessary.
BEFORE PROCEEDING TO
THE FINAL TESTING AND ADJUSTMENT OF THE DYNACLUTCH, ALL TENDENCY FOR
THE TROWEL BLADES TO ROTATE WHILE THE DYNACLUTCH LEVER IS IN THE
STOP (DISENGAGED) POSITION MUST BE ADJUSTED
OUT OF THE SYSTEM!
USE EXTREME CAUTION
WHEN PERFORMING THIS
TEST
1. Place the trowel in the center of a cleared
area at least 12 x 12 foot square. The
surface the trowel is tested on must be a
level, clean, dry and crack free section of
fully cured concrete.
4. Firmly holding the other end of the string
attached to the spark plug wire over head in
one hand, let go of the trowel handle and
step back out of the way.
NO ONE, BESIDES THE OPERATOR, SHOULD BE ALLOWED
WITHIN THIS AREA WHILE
THE TROWEL IS BEING
TESTED.
2. Tie one end of a 10 foot length of heavy
string to spark plug wire of the engine as a
safety precaution. The string must be tied
near the spark plug end of the wire, so that
the operator can pull the plug wire off of the
plug, to stop the engine if the Dyna-Clutch
is not adjusted properly and allows the
trowel to spin out of control.
MAKE SURE NO ONE IS IN
THE AREA BEFORE YOU LET
GO OF THE TROWEL.
If the Dyna-Clutch is correctly adjusted, the blades
will be disengaged from the engine (stopping their
rotation) within the first 3/4 revolution of the
handle. If the Dyna-Clutch does not disengage
properly and the trowel starts to spin out of control, immediately pull the string hard enough to
disconnect the spark plug wire and kill the engine.
DO NOT ATTEMPT TO GRAB
THE HANDLE TO STOP THE
TROWEL.

Final Testing and
BladeAdjustment
Maintenance
NOTE:
Be sure to watch for the
disengagement of the Dyna-Clutch. Even
if it disengages within the specified 3/4
revolution, the trowel handle may "coast"
an additional 1/2 to 3/4 revolution
depending on the condition of the floor.
This is acceptable as long as the DynaClutch has disengaged as specified, since
the handle will not be under power during
this "coasting" period.
If the trowel has been dropped or mishandled, the
spider and arms have been disassembled, the
blades replaced or bent arm adjustments made, the
following adjustment may be necessary to remove
excessive wobble:
5. If the Dyna-Clutch did not disengage
completely or soon enough, some final
adjustments will have to be made. Shut the
engine down, move the Dyna-Clutch lever to
the STOP position and loosen the (2) lock
nuts holding the cable housing in place.
Alternately turning each lock nut counter
clockwise, slightly decrease the amount of
tension on the control cable and spring to
allow the Dyna-Clutch to fully disengage
sooner. Tighten the (2) lock nuts against the
cable housing bracket to lock in the
adjustment.
6. Retest and readjust the trowel as
necessary to insure proper disengagement
of the Dyna-Clutch within the first 3/4
revolution of the handle.
BLADE ADJUSTMENT
1. Place (3) to (4) blocks of equal height
under the stationary blade guard (outer
ring) to raise the blades off the floor - make
sure the blocks clear the blades so they can
be rotated without interference.
Disconnect spark plug wire and move the
Dyna-Clutch lever to STOP (disengaged)
position.
2. Choose one of the blades and measure the
height of the leading edge of that blade
from the floor. Make a note of the
measurement, mark the blade and mark the
spot on the floor from which the
measurement was taken for reference.
3. Rotate the blades until the next blade is in
the same position as the first one was.
Measure the leading edge height of the
second blade from the spot marked on the
floor and compare this measurement with
one recorded from the first blade.

Maintenance
Bent Arm Adjustment
BENT ARM ADJUSTMENT
4. If the height of the second blade is not
within 1/32 of an inch of the height of the
first blade, the second blade must be
adjusted. To do this, loosen the (2) lock
nuts (A), and adjust the blade arm lever (B)
up or down as necessary to match the
second blade height to the first blade height
If the trowel still wobbles after adjusting the
blades as outlined above, it may have a bent
arm. If the arm is not bent too much, it can be
compensated for as follows:
1. Place trowel on a perfectly flat section of
concrete or floor. Disconnect spark plug
wire. Turn the tilt adjustment knob
counter clockwise until all tension is off
of the tilt adjustment cable and the
blades are flat against the floor. DO
NOT screw the knob completely out of
the handle.
within the specified 1/32 of an inch.
Tighten the (2) lock nuts securely when
proper adjustment is reached.
5. Repeat steps (3) and (4) for each of the
remaining blades.
2. Examine each arm to determine which
one is bent, all blades should be perfectly
flat to the floor along their length. When
the bent arm is located, loosen bolt (A) in
that arm approximately (3) to (4) turns.
Loosen lock nut (B) and tighten bolt (C)
until the blade lays flat against the floor.
Tighten lock nut (B) and tighten bolt (A)
to 14 lb. ft.

Bent Arm Adjustment
3. Check all blades again to make sure they
are flat on the floor. Double check blade
adjustment as outlined in the BLADE
ADJUSTMENT section above.
NOTE: If the trowel still wobbles after these
adjustments, or if an arm is bent bad enough that
it cannot be compensated for with the adjusting
bolts, the bent arm must be replaced, and the
trowel should be closely examined to make sure
that no other parts are bent or broken. All such
parts must be replaced before returning the
trowel to service.

Throttle Cable Attachment
THROTTLE CABLE ATTACHMENT
If the throttle cable is disconnected from the
engine for service or replacement, it must be
rerouted and reconnected to insure proper
operation. When removing the throttle cable
from the trowel, make a note of how it was
routed to the engine, and route the cable the
same way when it is reinstalled or replaced. To
reconnect the throttle cable to the engine correctly, consult the appropriate diagrams on these
two pages for the engine you are working with.
NOTE: On some engines, the throttle cable end
must be bent into the configuration shown in
diagram (X). All other engines require the cable
end to be left straight as shown in diagram (Y).
The required cable end is called out in each
cable hookup diagram with the appropriate note

Repairing Gearcase Assembly
1. Disassemble gear case and clean all bolts
thoroughly in paint thinner. Dry bolts and
apply Loctite primer #T747. Allow primer
to dry.
8. Install input shaft through opposite side of
case and install blind end side cover
without any shims or O-ring. Install four
(4) attaching bolts finger tight then 1/8 turn
with wrench. Do Not tighten. Using feeler
gauges, check for equal gap all around the
joint surface. Loosen and tighten the four
(4) attaching bolts until the gap is equal all
around. Note the feeler gage thickness
here. The measured thickness is the correct
amount of shimming required. (i.e. if
feeler gage amount is .027", then .027" is
correct amount of shim thickness for this
line only). Remove the attaching bolts and
remove the end cap by gently tapping the
sheave end of the shaft with a soft faced
mallet. Install the measured amount of
shims and a new O-ring (lightly lubricated)
to the cap and install and tighten cap to
case. (Use Loctite #242 or equivalent) and
check for ease of operation by rotating the
shaft in the assembly. Insure that there is
no end play in the assembly. If the shaft
does not rotate freely, more shims are
required. If end play is found, less shims
are required.
2. Wash all remaining parts thoroughly in
Safety Kleen solution or equivalent & dry
thoroughly before continuing.
3. Inspect condition of all components
including for good threads in tapped holes.
File or stone any "dings" or "burrs" on joint
surfaces. Stone (ONLY) any marks in the
bore areas.
4. Press off any worn components and
replace with new as required. If bearings
are being replaced, make certain to replace
both halves of the bearing (i.e. cup and
cone sections).
5. Press new components in place. If original
shafts are being retained but bearing have
been pressed off, use Loctite # 680 (or
equivalent) bearing locker to insure that
bearing is retained properly on the shaft.
The same applies to bearing parts removed
and installed into the bores of existing caps
or gearcase. Allow Loctite to cure before
proceeding.
6. Press out and replace all (3) seals. To
prevent oil leaks after reassembling, cover
keyways in both shafts with masking or
electrical tape to insure that the new seals
are not damaged during assembly.
7. Install new O-ring lightly lubricated to
sheave end side cover (P/N 42718) and
install to case using Loctite #242 (or
equivalent). Insure that the O-ring is not
cut during installation.
9. Repeat step 8 for the output shaft and its
cap with the following exception: After
measuring for Shim amount, subtract .003"
from the measurement.
(i.e. if
measurement is .027", .027" - .003" =
.024". .024" would be the correct shim
amount.)
10. After assembly is complete, insure ease of
rotation by rotating the input shaft.
Maximum allowable torque required is 7
lb. in. Refill the case with 40 oz. of 80W 90W oil through the oil sight plug hole and
reinstall the oil sight plug. The case is
ready for immediate use.
