General

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.

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.

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 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, 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.

2. Tilt steering column to UP position, slide seat assembly forward, open rear sliding window, and open hood to disconnect battery. See Figure 3 for lift truck models •

CAUTION DO NOT allow any fluid to drain when disconnecting the heater hose from the engine. The method will help when purging the system during installation. 5. Disconnect and cap heater hoses from engine. See Figure 6.

WARNING Replacement, installation and repairs to air conditioning units that require discharging and/or refilling 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 conditioning system.

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/ GDP18VX, GLP/GDP20SVX, GLP/GDP030VX (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 connection. 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 on quick disconnect fittings to disconnect heater hoses from heater assembly (see Figure 6). Disconnect heater wire harness connection. 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).
