SAFETY PRECAUTIONS :
- Be sure to read this service manual and understand the contents before proceeding with the work. Improper truck operation is dangerous and could result in injury or death. Be sure to familiarize yourself with the systems and components described herein before proceeding with removal or disassembly work.
- For heavyweight components, BE SURE to check the weight of each component beforehand by referring to this service manual. Also, for safety, use proper lifting equipment for removal/ installation work. Following is a list of basic precautions that should always be observed.
(1) Read and understand all warning plates and decals on the truck before proceeding with operation, lubrication, or repair work.
(2) Always wear safety glasses and protective shoes when working around trucks. Be sure to wear safety glasses to prevent any type of metal from getting into your eyes when using a hammer or sledge. Use welders gloves, hood/goggles, apron, and other protective clothing appropriate to the welding operation. Do not wear loose clothing or accessories that can be caught in moving parts. Do not wear rings when you work.
(3) Do not work on any truck that is supported only by lift jacks or a hoist. Always use blocks or jack stands to support the truck before proceeding with the work.
(4) Lower the forks or other implements to the ground before performing any work on the truck. If this cannot be done, make sure the forks or other implements are blocked correctly to prevent them from dropping unexpectedly.
(5) Use steps and assist grips (if equipped) when you mount or dismount the truck. Clean the steps, hand rails, and floor of operator seat beforehand. Always face the truck when using steps, ladders, and walkways. If you cannot use the designed access system, use ladders, scaffolds, or work platforms to ensure the safety at the workplace.
(6) To avoid back injury, use a hoist when lifting components which weigh 23 kg (51 lb) or more. Make sure all chains, hooks, slings, etc., are in good condition and are of the correct capacity. Be sure hooks are positioned correctly. Make sure the load is well balanced prior to lifting. (7) To prevent burns, DO NOT touch hot sections of the truck immediately after stopping the truck.
(8) Remove covers carefully. When removing the last two bolts or nuts, loosen gradually to release spring force or pressure.
(9) Be careful when removing filler caps, breathers and plugs on the truck. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure. Use extreme care immediately after stopping.
(10) Use well maintained tools in a proper way.
