■Maintenance and Schematics
❑Maintenance information
The parts drawings located in the repair parts
sections, are designed for use as a guide for proper
disassembly of the machine and components as
well as for parts replacement. Always refer to the
hydraulic system installation drawings and the
electrical wiring diagram before removing or
disassembling associated parts.
Do not attempt to disconnect or remove any
hydraulic line before reading and
understanding all text concerning the
system hydraulics. In most cases,
disassembly of the machine will be obvious
from the illustration.
DO NOT modify this ariel platform without
prior written consent of Snorkel Engineering
Department.
Modification may void the warranty,
adversely affect stability, or affect the
operational characteristics of the ariel
platform.
When disassembling or reassembling
components, complete the procedural steps in
sequence. Do not partially disassemble or
assemble one part, then start on another. Always
check your work to assure that nothing has been
overlooked.
The following list is a gentle reminder when
disassembling or assembling the machine.
MHP15J – 11995B page 5
CAUTION
CAUTION

üAlways be conscious of weight.
üNever attempt to lift heavy objects without the aid of
a mechanical device.
üDo not allow heavy objects to rest in an unstable
condition.
üAlways 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.
üWhen 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.
üIf a part resists removal, check to see if all fasteners,
electrical wiring, hydraulic lines, etc., have been
removed or that other parts are not interfering.
Parts should be thoroughly inspected before
restoring to service at the time of reassembly. Burrs,
nicks or scratches may be removed from machined
surfaces by honing or polishing with #600 crocus
cloth, followed by a thorough cleaning in an
approved cleaning solvent, and blown dry with
compressed air. Do not alter the contour of any part.
If this operation does not restore the part to a
serviceable condition, replace the part.
Replace all O-rings, seals, and gaskets at
reassembly. Use new roll pins or cotter pins. Dip all
packing rings and seals in hydraulic oil before
reassembling in cylinder and manifold installations.
Replace any part having imperfect threads. In
general, units that have been disassembled can be
reassembled by reversing the order of disassembly.
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.
Clearly mark or tag hydraulic lines and electrical
wiring connections when disconnecting or removing
them from unit. This will assure that they are
correctly reinstalled.
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:
üDaily Maintenance (Operator’s Inspection)
ü90 Day or 150 Hour (frequent) Maintenance
üYearly or 500 Hour (annual) Maintenance,
These schedules should ensure the detection of any
defective, damaged or improperly secured parts
and provide information regarding lubrication and
other minor maintenance items.
The Maintenance Schedule following, outlines the
requirements of these maintenance checks for each
time interval. The Operator’s Pre-operational
inspection must be performed by a trained operator.
All other maintenance and inspections must be
performed by a trained service technician only.
Note that the 90 Day or 150 hour (frequent) and
yearly or 500 hour (annual) Maintenance, require
use of the Preventive Inspection Maintenance
Checklist to pinpoint all inspection items. Retain a
copy of these forms for your records.
They also require that all placards and decals on the
unit are to be inspected.
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.
Snorkel recommends that you make additional
copies of the Preventive Inspection Maintenance
Checklist forms for your use in performing these
Failure to perform the Preventive
Maintenance at the intervals outlined in the
Maintenance Schedule may result in a unit
being operated with a defect that could result
in INJURY or DEATH of the unit operator. DO
NOT allow a unit to be operated that has been
found to be defective.
Repair all defects before returning the unit to
service.

■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.
❑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 dipstick
and should be checked with all cylinders fully
retracted and the platform in stowed position.
It is absolutely necessary that only new, clean
hydraulic oil is added.
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.
If questions still remain, contact Snorkel for further
information.

CAUTION

■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.
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.
If acid contacts eyes, flush immediately with
clear water and get medical attention.
Wear rubber gloves and protective clothing
to keep acid off skin, if acid contacts skin,
wash off immediately with clear water.
Lead-acid batteries produce flammable and
explosive gases. NEVER allow smoking,
flames or sparks around batteries.
