Jacking Safety
Jacking Safety General Precautions Some maintenance procedures require the lift truck to be elevated off the floor. When jacking the truck, observe the following safety precautions: 1. Lower the forks completely. Remove any load.
To elevate the lift truck: 1. Place a suitable jack under a designated jacking point. See Figure 2-2. 2. Lift the truck only as far as required to perform the procedure. 3. Securely block the truck in place. NOTE: It is possible to elevate the front of the lift truck without using a jack. a. Block the steerable wheels with chocks.
2. Set the parking brake and block the wheels to prevent movement of the vehicle.
b. Tilt the mast back and place blocks on the floor under the mast main frame.
3. Turn the key switch OFF and disconnect the battery connector.
c. Tilt the mast forward, lifting the truck off the floor.
4. Place the jack under the designated jacking points. See Figure 2-2. 5. Always use solid blocks to support the truck. Never rely on jacks or chains to support the truck.
Use extreme care whenever the truck is jacked up. Never block the lift truck between the telescopic and the floor. Use a suitable hoist to stabilize the mast. Keep hands and feet clear from vehicle while jacking the lift truck. After the lift truck is jacked, place solid blocks or jack stands beneath it to support it. DO NOT rely on the jack alone to support the lift truck. Figure 2-2.
