General

General WARNING The lift truck must be put on blocks for some types of maintenance and repairs. The removal of the following assemblies will cause large changes in the center of gravity: mast, drive axle, engine and transmission, and counterweight. When the lift truck is put on blocks, put additional blocks in the following positions to maintain stability: •

Before removing the mast and drive axle, put blocks under the counterweight so the lift truck cannot fall backward. Before removing the counterweight, put blocks under the mast assembly so the lift truck cannot fall forward.

The surface must be solid, even, and level when the lift truck is put on blocks. Make sure that any blocks used to support the lift truck are solid, one-piece units. See the Operating Manual or Periodic Maintenance 8000YRM1762.

NOTE: For exhaust system procedures on lift trucks equipped with a PSI 2.4L engine go to Fuel System PSI 2.4L 0900YRM1757. NOTE: For exhaust system procedures on lift trucks equipped with Kubota engine go to . NOTE: For exhaust system procedures on lift trucks equipped with Yanmar engine go toExhaust System Repair in this manual. This section contains the description of the frame and connected parts; procedures for removing and installing counterweight, hood, overhead guard, engine, transmission, cooling system, and exhaust system (see above NOTES). Checks for the operator restraint system and procedures for the repair of tanks and installation of safety labels are also included.

Description The frame is one weldment and includes the hydraulic tank and fuel tank for gasoline or diesel fuel. See Figure 1. There is a counterweight for each capacity of lift truck. The counterweights are similar in appearance, but are different weights. See Table 3 for lift truck models: •

Counterweight Replacement REMOVE WARNING The lift truck must be put on blocks for some types of maintenance and repair. The removal of the following assemblies will cause large changes in the center of gravity: mast, drive axle, engine and transmission, and counterweight. When the lift truck is put on blocks, put additional blocks in the following positions to maintain stability: •

Before removing the mast and drive axle, put blocks under the counterweight so the lift truck cannot fall backward. Before removing the counterweight, put blocks under the mast assembly so the lift truck cannot fall forward.

The surface must be solid, even, and level when the lift truck is put on blocks. Make sure that any blocks used to support the lift truck are solid, one-piece units. See the procedure How to Put Lift Truck on Blocks in the Operating Manual or the Periodic Maintenance Manual for your lift truck.

WARNING DO NOT operate the lift truck if the capscrew for the counterweight is not installed. When the capscrew is removed, the counterweight can fall from the lift truck.

WARNING LPG can cause an explosion. DO NOT cause sparks or permit flammable material near the LPG system. LPG fuel systems can be disconnected indoors only if the lift truck is at least 8 m (26 ft) from any open flame, motor vehicles, electrical equipment, or ignition source.

Overhead Guard Replacement

Overhead Guard Replacement REMOVE AND INSTALL WARNING DO NOT operate the lift truck without the overhead guard correctly fastened to the lift truck.

WARNING

3. The rear legs of the overhead guard have two capscrews that are located under the hood inside the engine compartment, next to the radiator. Remove and install the capscrews. See Figure 17. 4. Remove the fender cover, dash, and kick panel to remove and install the three capscrews on the front legs of the overhead guard. See Hood, Seat, and Side Covers Replacement for the removal procedures.

DO NOT weld mounts for lights or accessories to legs of the overhead guard. Changes that are made by welding, or by drilling holes that are too big or in the wrong location, can reduce the strength of the overhead guard.

5. When installing the overhead guard, tighten the capscrews for the overhead guard legs to 66 N•m (49 lbf ft). See Figure 17.

See your dealer for Hyster lift trucks BEFORE performing any changes to the overhead guard.

LED TAIL, BACKUP, AND BRAKE LIGHTS, REPLACE

NOTE: The lift trucks covered in this YRM are equipped with either a high or low overhead guard. The removal and installation procedures for both types of overhead guards are the same.

These light assemblies are nonrepairable and must be replaced as an assembly. See Electrical System 2200YRM1760 for the procedures to replace these lights.

No welding or drilling on legs of overhead guard is permitted as per previous WARNING. NOTE: The lifting device can be connected to any number of positions on the overhead guard depending upon the lifting device available. The ideal choices are a four point sling connected to all four corners on the top of the overhead guard, or a two point sling connected to two opposite corners of the overhead guard. If a single point hoist is used, make sure that the lift point is as close to the center of the overhead guard. If during the initial start of the lift the overhead guard is off balance lower immediately and move the hoist to a more centered point. 1. Connect a lifting device to remove or install the overhead guard. Loosen clamp and disconnect the air intake hose from the elbow. Remove bolts, elbow, retainer, and grommet from the overhead guard rear leg. See Figure 16. 2. Disconnect any wires between the frame and the overhead guard.

Operator Restraint System Replacement DESCRIPTION The seat belt, hip restraint brackets, seat and mounting, hood, and latches are all part of the operator restraint system. Each item must be checked to make sure it is attached securely, functions correctly, and is in good condition. See Figure 18.

Emergency Locking Retractor (ELR) When the ELR style seat belt is properly buckled across the operator, the belt will permit slight operator repositioning without activating the locking mechanism. If the truck tips, travels off a dock, or comes to a sudden stop, the locking mechanism will be activated and hold the operator's lower torso in the seat. A seat belt that is damaged worn or does not operate properly will not provide protection when it is needed.

20

The end of the belt must fasten correctly in the latch. The seat belt must be in good condition. Replace the seat belt if damage or wear is seen. See Figure 18 and Figure 19. NOTE: The following seat belt operation checks must be performed three times before replacing the seat belt assembly. •

With the hood closed and in the locked position, pull the seat belt slowly from the retractor assembly. Make sure the seat belt pulls out and retracts smoothly. If the seat belt cannot be pulled from the retractor assembly or the belt will not retract, replace the seat belt assembly.


0100 YRM 1754 •

With the hood closed and in the locked position, pull the seat belt with a sudden jerk. Make sure the seat belt will not pull from the retractor assembly. If the seat belt can be pulled from the retractor, when it is pulled with a sudden jerk, replace the seat belt assembly.

•

With the hood in the open position, make sure the seat belt will not pull from the retractor assembly. If the seat belt can be pulled from the retractor, with the hood in the open position, replace the seat belt assembly.
