2. SAFETY PRECAUTIONS
MAINTENANCE AND REPAIR
• The Service Manuals are updated on a regular basis, but may not reflect recent design changes to the
product. Updated technical service information may be available from your local authorized Yale®
dealer.
Service Manuals provide general guidelines for maintenance and service and are intended for use by
trained and experienced technicians. Failure to properly maintain equipment or to follow instructions con-
tained in the Service Manual could result in damage to the products, personal injury, property damage or
death.
• When lifting parts or assemblies, make sure all slings, chains, or cables are correctly fastened, and that the
load being lifted is balanced. Make sure the crane, cables, and chains have the capacity to support the
weight of the load.
• Do not lift heavy parts by hand, use a lifting mechanism.
• Wear safety glasses.
• DISCONNECT THE BATTERY CONNECTOR before doing any maintenance or repair on electric lift
trucks. Disconnect the battery ground cable on internal combustion lift trucks.
• Always use correct blocks to prevent the unit from rolling or falling. See HOW TO PUT THE LIFT TRUCK
ON BLOCKS in the Operating Manual or the Periodic Maintenance section.
• Keep the unit clean and the working area clean and orderly.
• Use the correct tools for the job.
• Keep the tools clean and in good condition.
• Always use YALE APPROVED parts when making repairs. Replacement parts must meet or exceed the
specifications of the original equipment manufacturer.
• Make sure all nuts, bolts, snap rings, and other fastening devices are removed before using force to re-
move parts.
• Always fasten a DO NOT OPERATE tag to the controls of the unit when making repairs, or if the unit
needs repairs.
• Be sure to follow the WARNING and CAUTION notes in the instructions.
• Gasoline, Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), and Diesel fuel are flammable.
Be sure to follow the necessary safety precautions when handling these fuels and when working on these
fuel systems.
• Batteries generate flammable gas when they are being charged. Keep fire and sparks away from the area.
Make sure the area is well ventilated.
NOTE: The following symbols and words indicate safety information in this man-
ual:
WARNING
Indicates a hazardous situation which, if not avoided, could result in death
or serious injury.
CAUTION
Indicates a hazardous situation which, if not avoided, could result in minor
or moderate injury and property damage.
On the lift truck, the WARNING symbol and word are on orange back-
ground. The CAUTION symbol and word are on yellow background.

The overhead guard is an integral part of operator
cab. The operator cab is installed on a platform above
main frame members. Step plates on both sides of lift
truck provide access to operator cab. The operator
cab is a separate unit and can be removed as a
complete unit from module and frame of the lift truck.

NOTE: The EZ Tank Bracket used on these trucks to
mount LPG tank onto counterweight come in two
styles. One style of bracket swings out to side of truck
and other swings out to side and drops down.
NOTE: On lift trucks equipped with LPG, make sure
to release EZ Tank Bracket before opening hood.
1. For lift truck models GLP/GDP16VX, GLP/

3. Disconnect air filter hose from rear left corner leg
of cab frame. See Figure 4.
WARNING
DO NOT disconnect the heater hoses from the en-
gine when the engine is hot or when the cooling
system is under pressure, to do so could cause
serious injury.
WARNING
DO NOT remove the radiator cap from the radiator
when the engine is hot. When the radiator is hot
and the cap is removed, the pressure is released
from the system and the steam and boiling cool-
ant can cause burns. Wait 30 minutes for the en-
gine to cool. Do a touch test by touching the radi-
ator with your hand. If the radiator is still hot to
the touch, wait another 30 minutes before at-
tempting to remove, check, or fix any part of the
cooling system.
NOTE: Removing radiator cap will help depressurize
cooling system.
4. Remove radiator cover to access radiator cap.
Remove radiator cap. See Figure 5.

11. CAUTION
DO NOT allow any fluid to drain when disconnect-
ing the heater hose from the engine. The method
will help when purging the system during installa-
tion.
5. Disconnect and cap heater hoses from engine.
See Figure 6.
WARNING
Replacement, installation and repairs to air condi-
tioning units that require discharging and/or refill-
ing of the refrigeration fluid must be performed by
a certified technician.
6. Contact a certified air conditioning specialist to
have the refrigerant extracted from the air condi-
tioning system.

WARNING
Make sure that the lifting device has a minimum
capacity to lift 500 kg (1100 lb).
28. Connect a lifting device to a spreader bar or lift
strap, that is through door openings at top of op-
erator's cab (under overhead guard structure).
Place material that will be a cushion at top of door
opening to prevent damage. Operate lifting device
just enough to correctly position spreader bar or
lifting strap on operator's cab. See Figure 21.
CAUTION
Lift the operator cab carefully. Check that all elec-
trical wires and attachments are disconnected
and are not damaged.
29. Carefully lift operator cab away from lift truck. Set
operator cab in a storage area and place blocks
under operator cab to make it stable and prevent
damage to parts still attached.

Remove
WARNING
DO NOT remove the radiator cap from the radiator
when the engine is hot. When radiator cap is re-
moved, the pressure is released from cooling sys-
tem. If cooling system is hot, the steam and boil-
ing coolant can cause burns.
Wait 30 minutes for the engine to cool. Do a touch
test by touching the radiator with your hand. If the
radiator is still hot to the touch, wait another 30
minutes before attempting to remove the radiator
cap.
NOTE: Removing radiator cap will help depressurize
cooling system.
1. Remove radiator cover to access radiator cap.
Remove radiator cap. See Figure 32.
WARNING
DO NOT disconnect the heater hoses from the
quick disconnect fittings (inside operator cab) or
engine when the engine is hot or under pressure.
Serious injury can occur.
NOTE: Removing right side door assembly requires
two people.
2. Disconnect heater hose quick disconnect fittings.
See Figure 33.

Clean
WARNING
Compressed air can move particles so that they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air is
away from all personnel. Wear protective goggles
or a face shield to prevent injury to the eyes.
Check door assembly and parts for oil, grease, dirt,
and other debris. Clean door assembly and parts with
a clean cloth, soap, and water. Compressed air can
be used to dry door assembly and parts.
Inspect
Inspect all hoses for cracks and wear. Replace dam-
aged hoses. Inspect seals around door window and
door lock assembly and replace if damaged. Check
door lock and latch assembly. Make sure it opens,
shuts, and locks door securely and there is no rust,
grease, oil, or dirt on door lock and latch assembly
parts. Inspect windows for cracks or chips. Replace
windows if damaged.
