The document provides instructions for removing an operator cab from a forklift. Key steps include: 1. Tilting the steering column, sliding the seat forward, opening rear doors/windows, and disconnecting the battery. 2. Disconnecting air filter hoses, radiator hoses, heater hoses, electrical connections, and removing doors. 3. Removing fasteners securing various cab components like the dash, kick panel, and seal plate. 4. Detaching the cab from the frame by removing front and rear mounting fasteners and carefully lifting the cab away using lifting straps or a spreader bar placed through the door openings.

2. 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.

REMOVE
NOTE: The LPG tank bracket used to mount the LPG
tank (if equipped) onto the counterweight comes 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 a LPG fuel sys-
tem, move the LPG tank and bracket to side of truck
before opening the hood.

4. 2. Loosen clamp and disconnect air filter hose from
elbow. Remove bolts, elbow, retainer, and grom-
met 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.
3. Turn knobs counterclockwise and remove radiator
cover to access radiator cap. Remove radiator
cap. See Figure 5.
