Safety Precautions
Know and understand the safety precautions before going on to next section.
WARNING
Failure to heed the following safety precautions could result in tip over, falling,
crushing, or other hazards leading to
death or serious injury.
• KNOW all national, state/provincial and local
rules which apply to your MACHINE and JOBSITE.
• TURN the main power disconnect switch OFF
when leaving the machine unattended. Remove
the key to prevent unauthorized use of the aerial
platform.
• WEAR all the protective clothing and personal
safety devices issued to you or called for by job
conditions.
• DO NOT wear loose clothing,
dangling neckties, scarves,
rings, wristwatches or other
jewelry while operating this lift.
• AVOID entanglement
ropes, cords or hoses.
with
• AVOID falling. Stay within the
boundaries of the guardrails.
• DO NOT raise the aerial platform in windy or gusty conditions.
SKYJACK, Page 4
• DO NOT increase the lateral
surface area of the platform.
Increasing the area exposed to
the wind will decrease machine
stability.
• DO NOT drive or elevate the
aerial platform if it is not on a
firm level surface. Do not drive
elevated near depressions
or holes of any type, loading
docks, debris, drop-offs and
surfaces that may affect the stability of the aerial platform.
• If operation in areas with
holes or drop-offs is absolutely necessary, elevated
driving shall not be allowed.
Position the machine horizontally only with the platform fully
lowered. After ensuring that
all 4 wheels or outriggers (if
equipped) have contact with
level firm surface, the aerial
platform can be elevated. After elevation, the drive function
must not be activated.
• Elevated driving must only
be done on a firm level surface.
• DO NOT ascend or descend
a grade when elevated. When
fully lowered, ascending or descending, only grades up to
rated maximum listed in Table
2-1a and Table 2-1b are permissible.

SKYJACK, Page 5
Safety Precautions (Continued)
• DO NOT overload the platform, the lift relief
valve does not protect against overloading when
the platform is elevated. (Machines without load
sensing)
• DO NOT attempt to free a snagged platform with
lower controls until personnel are removed from
the platform.
Jobsite Inspection
• Do not use in hazardous locations.
• Perform a thorough jobsite inspection prior to
operating the aerial platform, to identify potential
hazards in your work area.

platform is in the fully retracted position.
• Do use three points of contact to enter and
exit the platform. Enter and exit the platform
from the ground only. Face the machine when
entering or exiting the platform.
• Three points of contact means that two hands
and one foot OR one hand and two feet are in
contact with the aerial platform or the ground at
all times during entering and exiting.
WARNING
An operator should not use any aerial
platform that:
• does not appear to be working properly.

Troubleshooting Information - Introduction
The following pages contain a Table of Troubleshooting information for locating and correcting most service
trouble which can develop. Careful inspection and accurate analysis of the systems listed in the Table of Troubleshooting Information will localize the trouble more quickly than any other method. This manual cannot cover all
possible troubles and deficiencies that may occur. If a specific trouble is not listed, isolate the major component
in which the trouble occurs, isolate whether the problem is electrical or hydraulic, and then isolate and correct
the specific problem.
The content of this section is separated into “probable cause” and “remedy”. The information preceded by a
number represents the “probable cause”. The following line, noted by a dash and a greater indentation represents
the “remedy” to the “probable cause” directly above it. See example below for clarification.

Operator’s Responsibility For
Maintenance
Maintenance And Inspection
Schedule
Death or injury can result if the work platform is not kept
in good working order. Inspection and maintenance
should be performed by competent personnel who
are familiar with mechanical procedures.
The actual operating environment of the work platform
governs the use of the maintenance schedule. The
inspection points covered in the Maintenance and
Inspection Schedule (Section 2, Table 2-3.) indicates
the areas of the work platform to be maintained or
inspected and at what intervals the maintenance and
inspections are to be performed.
The operator should be assured that the work platform
has been properly maintained and inspected before
using it.
Even if the operator is not directly responsible for the
maintenance of this work platform, the operator should
perform ALL the daily inspections in the Maintenance
and Inspection Schedule (Table 2-3.) found in Section
2 of this manual.
Note
Replace all worn, damaged or missing parts or labels
discovered during this inspection.
Owner’s Annual Inspection Record
It is the responsibility of the owner to arrange daily,
weekly, monthly and annual inspections of the work
platform. The Owner’s Annual Inspection Record
(Table 2-1. in Section 2) is to be used for recording
the date of inspection, owner’s name and the person
responsible for the inspection of this work platform.
General Maintenance Hints
Danger
Crushing Hazard
DO NOT reach through scissors assembly without the
safety bar properly positioned. Failure to avoid this
hazard will result in death or serious injury!
SECTION 5, Page 2
•
Properly position maintenance bar if the scissor
assembly is raised.
•
Before attempting any repair work, disconnect
the battery ground (-) lead.
•
Preventive maintenance is the easiest and least
expensive type of maintenance.

Hydraulic System And Component
Maintenance And Repair
7.
The following points should be kept in mind when working on the hydraulic system or any component:
1.
Any structure has limits of strength and durability.
To prevent failure of structural parts of hydraulic
components, relief valves which limit pressure to
safe operating values are included in the hydraulic circuits.
2.
Tolerance of working parts in the hydraulic system are very close. Even small amounts of dirt
or foreign material in the system can cause wear
or damage to components, as well as general
faulty operation of the hydraulic system. Every
precaution must be taken to assure absolute
cleanliness of the hydraulic oil.
3.
Samples of hydraulic oil should be drawn from
the reservoir every six months. These samples
should be about two quarts and should be taken
while the oil is warmed through normal operation
of the system. If possible, the sample should be
analyzed by a qualified lubrication specialist to
determine whether it is suitable for further use.
The intervals between oil changes depend on
operating conditions and on the care used in
keeping the oil clean.
4.
5.
6.
Whenever there is a hydraulic system failure
which gives reason to believe that there are metal
particles or foreign materials in the system, drain
and flush the entire system and replace the filter
cartridges. A complete change of oil must be
made under these circumstances.
Whenever the hydraulic system is drained, check
the magnets in the hydraulic reservoir for metal
particles. If metal particles are present, flush the
entire system and add a new change of oil. The
presence of metal particles also may indicate the
possibility of imminent component failure. A very
small amount of fine particles is normal.
DO NOT use synthetic or fire resistant oils in this
work platform. Use ATF Dexron III (ESSO) or
equivalent hydraulic oil. For conditions causing
oil temperatures below -31°F (-35°C) and above
122°F (50°C) consult Skyjack, Inc.
119153
8.
9.
All containers and funnels used in handling
hydraulic oil must be absolutely clean. Use a
funnel when necessary for filling the hydraulic
oil reservoir, and fill the reservoir only through
the filler opening. The use of cloth to strain the
oil should be avoided to prevent lint from getting
into the system.
When removing any hydraulic component, be
sure to cap and tag all hydraulic lines involved.
Also, plug the ports of the removed components.
All hydraulic components must be disassembled
in spotlessly clean surroundings. During disassembly, pay particular attention to the identification of parts to assure proper reassembly. Clean
all metal parts in a clean mineral oil solvent. Be
sure to thoroughly clean all internal passages.
After the parts have been dried thoroughly, lay
them on a clean, lint-free surface for inspection.
10. Replace all o-rings and seals when overhauling
any component. Lubricate all parts with clean
hydraulic oil before reassembly. Use small
amounts of petroleum jelly to hold o-rings in
place during assembly.
11. Be sure to replace any lost hydraulic oil when
completing the installation of the repaired component, and bleed any air from the system when
required.
12. All hydraulic connections must be kept tight. A
loose connection in a pressure line will permit
the oil to leak out or air to be drawn into the
system. Air in the system can cause damage
to the components and noisy or erratic system
operation.
MAINTENANCE. Three simple maintenance procedures have the greatest effect on hydraulic system
performance, efficiency and life. Yet, the very simplicity
of them may be reasons they are so often overlooked.
What are they? Simply these:
1.
Change filters regularly.
2.
Maintain a sufficient quantity of clean hydraulic oil
of the proper type and viscosity in the hydraulic
reservoir.
3.
Keep all connections tight.

HOURS COUNTER:
The hours counter records pulsing hours, and is displayed when the calibrator is first plugged in. Once the
SELECT button is pressed, the calibrator reverts to normal operation.
Initially a minute/seconds count is displayed. By pressing the (-) button, hours are displayed
and by pressing the (+) button 1000’s of hours are displayed.
Releasing the buttons reverts back to the minute/seconds display. The decimal point blinks every second during
drive. The counter will record up to 65,500 hours before rolling back to 0.
DIAGNOSTIC PROCEDURE:
WARNING
All machine functions remain operational while calibrator is plugged in.
The last five segments on the bar display are as follows.
BATT
Displays the current battery voltage. Pressing the (+) button displays the highest voltage, for the machine, that the Sevcontrol has recorded.
MOTOR V.
Displays the motor voltage as the machine is being driven.
MOTOR AMP Displays the motor current as the machine is being driven.
TEMP
Displays the temperature of the MOSFET heat sink in °C. Pressing the (+) button displays the highest temperature recorded and pressing the (-) button displays the lowest temperature recorded.
TEST
This invokes the diagnostic test routines to check machine switches, joystick,
control wiring etc.
With the calibrator connected and the platform powered up, as described in the adjustment procedure. Use the
SELECT button to select the test segment. If the SELECT button is pressed at any time during the test, the test
will be terminated and the minute/seconds count will be displayed.
The first test displayed, on the drive Sevcontrol, is the joystick input. This displays the input as 0-100% as joystick
is moved from min. to max.
Pressing the (+) and (-) buttons step through the tests as shown in Table 5-5. After the final test, the sequence
will loop back to the joystick input test, then test 1.

Tachometer Generator Testing Procedure
1.
Locate tachometer generator on back of drive motor. Remove rubber boot from the rear of the tachometer
generator.
2.
Mark the location of the wires attached to the generator and remove wires. NOTE: Wires must be
reattached to the same terminals as they were removed from or the Sevcon controller will not function
when reassembled.
3.
Remove the four 5/16-18 x 1-1/2” bolts securing the tachometer generator mounting plate to the rear of
the motor.
NOTE: Do not attempt to remove the tachometer generator from mounting plate until it has been determined
to be defective.
4.
Remove the coupler half from the tachometer generator and attach generator to a drill with a 1000-RPM
rating.
5.
Attach a voltmeter to the terminals on the rear of the tachometer generator and set the meter for D.C.
voltage.
6.
Energize drill and read voltage on meter. At 1000-RPM voltmeter should indicate (20.8) volts. If reading
is lower the tachometer generator is defective.
7.
Put the drill in reverse and energize drill, read voltage on meter. At 1000-RPM voltmeter should read (-20.8)
volts. If reading is lower the tachometer generator is defective.
Note
Steps #6 and #7, the voltage should be a smooth incline to proper voltage.
If voltage is erratic it may affect the performance of the machine.

PARTS MANUAL
GENERAL
The information contained in this section is designed
to aid the user in locating and identifying replacement
parts. Component parts of various assemblies and
sub-assemblies comprising the work platform are
illustrated and accompanied by a descriptive parts list.
Exploded drawings are used to show relative location of
component parts in disassembly order. If a part cannot
be found in this section, order by work platform model
number and serial number, giving a complete description
of the part.
PARTS ORDERING INFORMATION
When ordering replacement parts, the complete part
number and description should be used to ensure
proper identification and delivery of the desired item.
This complete identification should also be used when
requesting equipment information.
METHOD OF LISTING
Parts are listed in order according to the reference
number shown in the illustration, followed by a full
description based upon the “NOUN FIRST” method.
That is, the noun name of the part is listed first, then
the modifying description information which serves to
specifically identify the item. For example: PIN, Clevis.
Assemblies or groups are shown at the beginning of a
parts list and are identified with the letter references A, B,
C, etc. Individual parts in these lists have corresponding
letters after their description to identify which assembly or
group it is used in. Individual parts without identifying
letters are used in all the assemblies or group shown at
the beginning of the parts list. Descriptions preceded
with an (•) indicates a serviceable component or

the assembly. If quantity is (AR), it is understood that
the quantity may vary when machine is equipped with
certain options. Order quantity as needed.
HARDWARE
Standard screws, washers, nuts, etc. are not identified
by a reference number. These parts are known as
COMMON HARDWARE items and appear indented
under the major items with which they are used. They
should be ordered separately as listed, since they are
not component parts of the pieces they attach to.
