Maintenance Information
■About this Manual:
This Maintenance and Repair Parts manual covers
current production machines only.
While Snorkel has attempted in every way to
confirm that all information in this manual is correct,
improvements are being constantly made to the
machine that may not be reflected in this manual.
NOTE:
It is recommended that you record the serial and
model number of your machine (see page 17 of this
chapter). This information is found on the serial
number placard.
■Manual Organization
The Repair Parts Manual consists of six sections
with an individual table of contents preceding
sections 1 through 4.
Subassemblies and detailed parts are identified by
index numbers on the drawings that correspond to
the item numbers on the parts listing. When

■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 drawing.
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. Always check your work to assure that
nothing has been overlooked.
The following list is a gentle reminder when
disassembling or assembling the machine.
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.
CAUTION
CAUTION

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.

Inspected by: Date:

■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. Wipe away all excess lubricant from
exposed surfaces. Over lubrication can collect dirt
and foreign matter which acts as an abrasive.
NOTE
Any time the work platform is elevated to perform
maintenance work, properly position the safety bar
as outlined on the safety prop decal.
DO NOT reach through scissors mechanism
unless the safety prop is properly
positioned.
INJURY or DEATH could occur if the
platform is not supported by the safety prop
and should suddenly drop onto personnel
performing maintenance work under the
raised platform.
❑King pins
King pin bearings are self lubricating. Check for
signs of damage and excessive wear as outlined in
the maintenance schedule.
❑Tie rods
Tie rod bearings are self lubricating. Check for
damage and excessive wear as outlined in the
maintenance schedule.
❑Steer cylinder end
Steer cylinder ends are self lubricating. Check for
damage and excessive wear as outlined in the
maintenance schedule.
❑Wheel bearings drive wheels
Wheel bearings used on drive wheels are sealed
bearings and do not require lubrication.
❑Hydraulic oil reservoir
The fluid level should be kept level with the
indicator line on the side of the reservoir and should
be checked with all cylinders fully retracted and the
platform in the stowed position.
The interior of the reservoir should be wiped out
and cleaned each time the hydraulic oil is changed.
The reservoir filler/breather cap should be
removed and the cap breather cleaned yearly with
Kerosene, Fuel Oil or other solvent.
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.
❑Return filter
On scissorlift models, the hydraulic oil return filter
is mounted in the left hand tray assembly close to
the hydraulic oil reservoir.
The filter element is a throw-away type filter and
should be changed after the initial break-in period
(approximately 50 hours operation time).
The filter condition should be checked at the 90 day
or 150 hour Preventive Inspection Maintenance
interval or more frequently under extreme working
conditions.
When changing the filter element, the oil inside of
the filter element, should be examined for deposits
of metal cuttings, which if present, could indicate
Maintenance Information
DANGER
CAUTION

excessive wear in some of the system components.
❑Door hinges and latches
Door hinges and latches may be lubricated as
required with spray lubrication or SAE 10W oil.
After lubricating, remove any excess oil or
over-spray so it will not collect dirt and debris.
❑Slide pads
Check slide pads for excessive wear and replace as
required.
❑Scissor arm bearings
Scissor arm bearings are self lubricating. Check
bearings for signs of damage and excessive wear
as outlined in the maintenance schedule.
■Batteries
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.
Check specific gravity of the battery per
maintenance schedule.
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.
■Rough Terrain Scissor Interlock Tests
The Snorkel S/RT Series are fitted with a very
important safety feature, a ‘Stabiliser/axle/scissor
Interlock’ system that prevents the stabilisers being
moved while the platform is elevated, and prevents
the platform being raised if the rear axle is oscillated
and the stabilisers are not set or the machine is
tilted.
The correct operation of the Stabiliser/scissor
Interlock is critical to ensure that the Scissor is
operated safely and with minimum risk.
To ensure the interlock system is functioning
correctly, before operating the Scissor the
following test must be carried out prior to
operation each day, in conjunction with all
other relevant daily pre-operational checks:
❑Stabiliser locked out when platform
elevated test
1. Position the machine on a firm level surface.
2. From the platform controls, start the engine
and allow it to warm up.
3. Raise the platform above the elevation
height (approx. 1.5 metres, depending on
model).
4. Operate the right front stabiliser extend
switch while watching the stabiliser leg for
movement
5. If the stabiliser leg moves, release the switch
immediately!
Lower the platform fully, remove the machine
from service and affix a Danger Tag warning
others that the machine is not to be used.
In the first instance contact the owner who
will then contact the Snorkel branch or
authorised agent to inspect, repair and test
the machine before allowing it to be placed
back into service.
If the stabiliser leg does not move, continue
to step 6
6. Lower the platform to the stowed position
❑Elevation locked out when axles not
stowed test
7. Park the machine such that one rear wheel is
in a depression (approx. 100mm deep) such
that the axle switch opens. A kerb or gutter
may be sufficient

model).
9. At this point, an alarm will sound and further
lift or drive will be disabled.
10. If there is no alarm and/or the machine
continues to allow lift stop immediately!
Lower the platform fully, remove the machine
from service and affix a Danger Tag warning
others that the machine is not to be used. In
the first instance contact the owner who will
then contact the Snorkel branch or
authorised agent to inspect, repair and test
the machine before allowing it to be placed
back into service.
11. Repeat steps 7-10 for the opposite rear
wheel.
12. Lower the platform to the stowed position
❑Elevation locked out when tilted test
13. Park the machine on ground known to
exceed the tilt limit specified on the serial
plate.
14. Raise the platform above the elevation
height, (approx. 1.5 metres, depending on
model).
15. At this point, an alarm will sound and further
lift or drive will be disabled.
16. If there is no alarm and/or the machine
continues to allow lift stop immediately!
Lower the platform fully, remove the machine
from service and affix a Danger Tag warning
others that the machine is not to be used. In

Control System Information
■Scissor Lift Control System
GP400C Control Board
EZcal
The EzCal LCD Display is a diagnostic tool for the
control system. It is intended to be used primarilyby
trained technicians. The EzCal LCD display gives
some information for the machine operator.
❑Work time
The EzCal default state is to display machine work
time. It accumulates time when ever the control
system is active. This can be re set by a qualified
technician. This value can be used to tell when
periodic maintenance is due.
❑Water
If the engine becomes too hot the EzCal LCD
display will show “Shut down - Engine Too Hot”
❑Alternator
If the alternator is not providing sufficient charge
the EzCal LCD display will show “Shut down - Not
Charging”
❑Oil Pressure
If the engine does not have sufficient oil pressure
the EzCal LCD display will show “Shut down - No
Oil Pressure”
❑Other messages
Other general messages may be displayed at the
time a machine state is not allowed e.g. Functions
Locked – Outriggers.
This is a guide to the operator to understand why
the machine is not doing what is desired. The
messages encompass many possible issues.
In the above case it could mean that the outriggers
can not be used because the platform is raised, or it
could mean that platform can not be raised
because the outriggers are not properly set.
■GP400 Menus Available with EZcal
When the EZcal LCD is in Technician Mode, a two
line display shows various menus and settings.
At any time the top line of the display describes the
currently selected menu and the bottom line shows
