PRECAUTIONS WHEN CARRYING OUT OPERATION
[When carrying out removal or installation (disassembly or assembly) of units, be sure to follow the general pre-
cautions given below when carrying out the operation.]
1. Precautions when carrying out removal work
• If the coolant contains antifreeze, dispose of it correctly.
• After disconnecting hoses or tubes, cover them or fit blind plugs to prevent dirt or dust from entering.
• When draining oil, prepare a container of adequate size to catch the oil.
• Confirm the match marks showing the installation position, and make match marks in the necessary places
before removal to prevent any mistake when assembling.
• To prevent any excessive force from being applied to the wiring, always hold the connectors when discon-
necting the connectors. Do not pull the wires.
• Fit wires and hoses with tags to show their installation position to prevent any mistake when installing.
• Check the number and thickness of the shims, and keep in a safe place.
• When raising components, be sure to use lifting equipment of ample strength.
• When using forcing screws to remove any components, tighten the forcing screws uniformly in turn.
• Before removing any unit, clean the surrounding area and fit a cover to prevent any dust or dirt from enter-
ing after removal.
