General
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.
See Figure 1.

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/
GDP18VX, GLP/GDP20SVX, GLP/GDP030VX
(C810), tilt steering column to UP position, slide
seat assembly forward, open rear door, and open
hood to disconnect battery. See Figure 2.
2. Tilt steering column to UP position, slide seat as-
sembly forward, open rear sliding window, and
open hood to disconnect battery.

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.

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.
NOTE: Step 7 is for lift truck models GLP/
GDP40VX5/VX6; GLP/GDP45SVX5, GLP/

090, 100, 110, 120VX) (G813, H813, J813) with a
Cummins QSB 3.3L or a Kubota diesel engine.
7. If lift truck cab is equipped with an air conditioner/
heater unit, disconnect AC refrigerant hoses from
refrigerant compressor.

NOTE: Removing door assemblies requires two peo-
ple.
8. Open left side door, remove lock nut, and discon-
nect gas spring from cab mounting bracket. See
Figure 9.
9. Lift left side door up and over hinge pin and set
aside. See Figure 10.
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,
to do so could cause serious injury.
10. Disconnect heater hose quick disconnect fittings.
a. For lift truck models GLP/GDP16VX, GLP/
(C810), open right side door and push buttons
on quick disconnect fittings to disconnect
heater hoses from heater assembly hoses (see
Figure 6). Disconnect heater wire harness con-
nection. See Figure 11.
b. For lift truck models GLP/GDP20-35VX
(GP/GLP/GDP040-070VX) (B875, C875), open
right side door and remove radiator cover to
access quick disconnect fittings. Push buttons
heater hoses from heater assembly (see Fig-
ure 6). Disconnect heater wire harness con-
nection. See Figure 11.
c. For lift truck models GLP/GDP40VX5/VX6;
GLP/GDP45SVX5, GLP/GDP45VX6; GLP/
GDP50-55VX (GP/GLP/GDP080, 090, 100,
110, 120VX) (F813, G813, H813, J813), open
right side door and located on inner rear cover
there are two port holes (see Figure 6). Push
buttons on quick disconnect fittings to discon-
nect heater hoses from heater assembly and
disconnect heater wire harness connection.

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.

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.
