SAFETY PRECAUTIONS:
The most important point in providing repair service is safety. To ensure safety, observe the general cautions described below.
- This manual is intended for properly trained and equipped service technicians.
- Any work on the machine must be performed by the trained personnel only.
- Carefully read this manual to thoroughly understand the operation method before you operate or repair the machine.
- Be sure to wear appropriate clothes and protectors, such as safety boots, hard hat and goggles.
- Place the machine on level and solid ground, and place chocks against the wheels to prevent movement.
- Remove the cable from the battery before starting the service work, and attach a “DO NOT OPERATE!” tag to the steering wheel.
- Be sure to release the internal pressure before you remove a pipe, such as the hydraulic oil, air, or engine coolant pipe.
- Be sure to apply the articulation stopper before starting work.
- While supporting the bottom of the chassis using a jack, be sure to support the chassis using the blocks.
- When the boom or bucket is raised or when a unit is lifted by a crane, be sure to place a stand or adequate cribbing under the unit to prevent unexpected dropping.
- Do not start to work in an enclosed area if adequate ventilation is not provided.
- To remove a heavy unit (20kgf (40 lbs) or more), be sure to use a crane or other lifting tool.
- Just after stopping operation, be careful not to directly touch a hot component. You may get burned.
- Contact tire manufacturer’s local dealer for tire servicing and changing.
- Always store the tools in good condition, and use them properly.
- Keep the work area clean. Clean up spills immediately.
- Avoid the use of flammable solvents and cleaners.
- When working outdoors keep work areas, ladders, steps, decks and work platforms clear of snow, ice, and mud.
- Use safe work platforms to reach higher areas of the machine.
