SAFETY
PRECAUTIONS FOR MAINTENANCE
Removing battery cables
Before repairing the electrical system or carrying out electrical welding, turn the starting switch OFF. Wait for
approximately 1 minute, then remove the negative (-) battery cable to stop the flow of electricity.
For machines equipped with a battery disconnector switch, set the battery disconnector switch to the OFF
position.
For details, see "HANDLING BATTERY DISCONNECT SWITCH (PAGE 3-67)".
Danger of sparks
There is hazard that sparks will be generated, so always observe the following.
Do not let tools or other metal objects make any contact between the battery cables. Do not leave tools lying
around near the battery.
When removing the battery cables, remove the ground cable (negative (-) cable) first. When installing,
connect the positive (+) cable first, then connect the ground.
Tighten the battery cable terminals securely.
Secure the battery firmly in the specified position.
PRECAUTIONS WHEN USING HAMMER
When using a hammer, pins may fly out or metal particles may be
scattered. This may lead to serious personal injury or death.
Always do as follows.
When hitting pins or bucket teeth, there is a hazard that broken
pieces might be sent flying and injure people in the surrounding
area. Always check that there is no one in the surrounding area.
If hard metal parts such as pins, bucket teeth, cutting edges, or
bearings are hit with a hammer, there is a hazard that pieces
might be scattered and cause serious personal injury or death.
Always wear safety glasses and gloves.
If the pin is hit with strong force, there is a hazard that it may fly
out and injure people in the surrounding area. Do not allow
anyone to enter the surrounding area.
PRECAUTIONS WITH HIGH-TEMPERATURE COOLANT
To prevent burns from boiling water or steam spurting out when
checking or draining the coolant, wait for the coolant to cool down
to a temperature where the radiator cap can be touched by hand.
Then loosen the cap slowly to release the pressure inside the
radiator, and remove the cap.
