page 5
ü Always be conscious of weight.
ü Never attempt to lift heavy objects without the aid of
a mechanical device.
ü Do not allow heavy objects to rest in an unstable
condition.
ü Always make sure work platform is in stowed
position - blocked or the weight removed by a
suitable lifting device before disconnecting the
hydraulic hose from the motor/pump unit to the lift
cylinder.
ü When raising a portion of the machine, be sure that
adequate blocking is properly positioned - Do not
depend on lifting device to hold and secure weight.
Proper assembly is critical to the successful
rebuilding of any unit. Carefully inspect any parts
which are to be reused. If in doubt, replace.
“SAFETY FIRST” is a good slogan.
Replace any guards and protective devices that
have been removed to carry out maintenance and
repair work.
■ Maintenance schedules
Snorkel has established a Preventive Maintenance
Schedule that includes:
ü Daily Maintenance (Operator’s Inspection)
ü 90 Day or 150 Hour (frequent) Maintenance
ü If a part resists removal, check to see if all fasteners, ü Yearly or 500 Hour (annual) Maintenance,
electrical wiring, hydraulic lines, etc., have been
removed or that other parts are not interfering.
These schedules should ensure the detection of any
defective, damaged or improperly secured parts
Parts should be thoroughly inspected before and provide information regarding lubrication and
restoring to service at the time of reassembly. Burrs, other minor maintenance items.

Remember that the service life of a machine can be
increased by keeping dirt and foreign materials out
of the vital components. Precautions have been
taken to safeguard against this; shields, covers,
seals and filters are provided to keep air and oil
supplies clean; however, these items must be
maintained on a scheduled basis in order to function
properly.
At any time air or oil lines are disconnected, clean
surrounding areas as well as the opening and
fittings themselves. As soon as a line or component
is disconnected, cap or cover all openings to prevent
the entry of dirt or foreign materials.
New parts should remain in their container until they
are ready to be used.
All placards and decals must be in place and legible.
Use the placards installation drawing and parts
listing in the repair parts section 1 of this manual to
check these placards and decals.

■ Lubricants
Specific lubricants as recommended by Snorkel,
should be used in maintaining your unit. If in doubt
regarding the use of lubricants other than those
listed, contact Snorkel.
❑ Pressure gun application
Service all fittings as indicated in the Maintenance
Schedule and lubrication illustration. Wipe away all
excess lubricant from exposed surfaces. Over
lubrication can collect dirt and foreign matter which
acts as an abrasive. Lubrication of accessory
equipment should be in accordance with the
manufacturer’s recommendations.
❑ Rotation bearing
Rotation bearing. Pressure gun lubricate bearing at
recommended interval using lubricant as outlined
in the maintenance schedule. Rotate while
lubricating. Lubrication fitting is located on the font
plate of the turntable.
❑ Rotation gear teeth and pinion
Rotation gear teeth and pinion. Gear teeth and
gear box pinion should be lubricated with a multi
purpose grease.
MHP12/34J – 11447B
❑ Engines
Engine. Refer to the engine manufacturer’s
instruction manual or consult your local engine
service representative if engine adjustments or
repairs are needed. The engine MUST be operated
in accordance with manufacturer’s instructions and
serviced at recommended intervals.
❑ Hydraulic oil reservoir
Hydraulic oil reservoir. The fluid level should be
kept between the low and full marks on the sight
gauge indicator and should be checked with all
cylinders fully retracted and the platform in stowed
position.
The interior of the reservoir should be wiped out
and cleaned each time the hydraulic oil is changed.
It is absolutely necessary that only new, clean
hydraulic oil is added.
CAUTION
If it becomes necessary to add or use an oil
other than the recommended fluid, it is
important that it be compatible and
equivalent to the factory fill. Local oil
suppliers can generally furnish this
information.
page 9
If questions still remain, contact Snorkel for further
information.
❑ Return filter
Lead-acid batteries contain sulfuric acid
which will damage eyes or skin on contact.
When working around batteries, ALWAYS
wear a face shield to avoid acid in eyes.
Return filter. On MHP12/34J models, the hydraulic
oil return filter is mounted in hydraulic oil reservoir.
If acid contacts eyes, flush immediately with
clear water and get medical attention.
The filter element is a throw-away type filter and
should be changed after the initial break-in period
(approximately 50 hours operation time).
Wear rubber gloves and protective clothing to
keep acid off skin, if acid contacts skin, wash
off immediately with clear water.
The filter is equipped with an (optional) hydraulic
pressure gauge to indicate the filter element
condition. A by-pass relief within the filter base is
provided and is set to by-pass at 25 PSI. If pressure
readings are above 25 PSI, the filter should be
changed.
Lead-acid batteries produce flammable and
explosive gases. NEVER allow smoking,
flames or sparks around batteries.
The filter condition should be checked at the 90 day
or 150 hour Preventive Inspection Maintenance
interval or more frequently under extreme working
conditions.
The filter condition indicator is accurate only when
the engine is running at maximum RPM and pump is
discharging maximum flow, which occurs only
during full speed. This requires that the indicator be
observed while the unit is in motion. Oil temperature
should be at least 70 degrees.
CAUTION
Use extreme caution while observing the
condition indicator because of the motion of
the boom. The condition indicator is best
observed from outside of the tract of the
vehicle wheels to avoid a possible unsafe
condition.
When changing the filter element, the oil inside of
the filter element, should be examined for deposits
of metal cuttings, which is present, could indicate
excessive wear in some of the system components.
■ Battery
Battery. The battery will have longer life if the water
level is maintained and it is kept charged. The unit
will have better starting characteristics with a fully
charged battery.
In cold weather the battery should be maintained at
full charge to keep from freezing. An extremely low
or dead battery can freeze in cold weather. Make
sure connections are clean and tight.
Make sure charging equipment is operating
properly.
