Charging
1. Disconnect the battery cables from the
battery.
2. Place the battery and battery charger in a
well-ventilated location.
3. Remove the battery caps.
4. Secure the positive (+) charge clip of the
charger to the positive (+) terminal of the
battery.
5. Secure the negative (-) charge clip to the
negative (-) terminal of the battery.
6. Adjust the charger voltage to the proper
voltage setting and charge the battery.
Do not set the charge current to exceed 1/10 of
the rated capacity of the battery, or, in case of
quick charge, set the rated capacity to the size of
the battery or smaller.
Stop charging once charging is completed or if the
battery overheats (fluid temperature exceeds
45°C). Continued charging after charging is
completed will:
• Overheat the battery
• Reduce electrolyte level and cause leaks
• Cause internal damage to the battery
Using Battery Booster Cables
Before using battery booster cables, read the
following safety precautions and the “Battery
Precautions” on page 5-52.
WARNING! The following safety messages
address a potential Fire and Explosion
Hazard:
• The battery produces hydrogen gas. The gas
will ignite if sparks are created when
connecting and disconnecting the booster
cables. Always make the last connection at
the furthest location possible from the
battery.
• Never allow the positive (+) and negative (-)
terminals to contact each other when
connecting or disconnecting the booster
cables.
• Do not allow the working machine to contact
the failed machine when connecting or
disconnecting the booster cables.
WARNING! Burn Hazard. Wear goggles and
rubber gloves when connecting and
disconnecting booster cables.
Connecting Booster Cables
Use the following procedure when connecting
booster cables to start the engine.
Use booster cables and clamps of appropriate
size for the battery capacity.
The battery in the working machine and failed
machine should be of the same capacity.
1. Before connecting, verify the cable and
clamps are not corroded or damaged.
Replace as needed.
2. Verify connection polarity before connecting
the cables.
