9. Precautions for Servicing
1-21
WARNING
These instructions should be strictly followed for the safety of you, others and your machine.
• Leaks of fuel and oil could cause a fire.
• Do not bend a high-pressure hose forcibly, or strike it with a hard object. Because abnormally bent
or damaged piping, tubes, and hoses easily burst under high pressure, never use them.
• The hydraulic system for the implement operates under high pressure.
When replenishing or draining hydraulic oil, be sure to first relieve the high pressure.
• The emission of hot oil under high-pressure from a small leak could result in serious bodily injury.
Wear safety goggles and thick gloves when checking for leaks. Use a piece of cardboard or a ply-
wood block to detect emissions of hot oil.
If the hot oil should contact your body, obtain prompt medical treatment.
• The engine cooling water and each lube oil system are still under high temperature and pressure
immediately after the engine has stopped. Removing caps, draining oil and water, or replacing filter
elements at that time may cause a burn. Wait until the temperature drops, then begin servicing in
accordance with the procedures described in this manual.
For cleaning the inside of the cooling system, refer to Section "25-
2. Nonperiodic services".
For checking the level of the cooling water and the hydraulic oil,
refer to Section "25-3. Checking before start-up".
For checking the oil levels in various systems and replenishing
the oil, refer to Section "25-3 to 5. Periodic services".
For replacing the oils in various systems and replacing the filter
elements, refer to Section "25-6 to 8. Periodic services".
