BATTERIES
The battery pack for this tool is equipped with nickel-cadmium
rechargeable batteries. Length of service from each charging
will depend on the type of work you are doing.
The batteries in this tool have been designed to provide
maximum trouble-free life. However, like all batteries, they
will eventually wear out. Do not disassemble battery pack
and attempt to replace the batteries. Handling of these
batteries, especially when wearing rings and jewelry, could
result in a serious burn.
To obtain the longest possible battery life, we suggest the
following:
n Remove the battery pack from the charger once it is fully
charged and ready for use.
For battery storage longer than 30 days:
n Store the battery pack where the temperature is below
80°F.
n Store battery packs in a “discharged” condition.

jaws securely. Tap the hex key sharply with a mallet in
