Table 1
Cause of Shutdown
Automatic shutdown initiated by excessive load (*1)
Automatic shutdown initiated due to the tool's internal
temperature exceeding the specifi ed temperature level (*2)
*1 Excessive load protection function
For excessive load conditions, the tool will shutdown to
prevent damage.
Discontinue the heavy load task, unplug the power
supply cord from the electrical outlet and plug it back in
to reset.
*2 Increased temperature protection function
Automatic shutdown is activated to prevent damage
from high temperatures.
The tool's internal temperature will increase for tasks
involving the use of large currents of electricity, or when
used in high temperature environments.
Please allow the tool to rest for 10 to 15 minutes before
continuing a task.

MAINTENANCE AND INSPECTION

1. Inspecting the socket
A worn or deformed hex or a square-holed socket will
not give an adequate tightness to the fi tting between the
nut or anvil, consequently resulting in loss of tightening
torque. Pay attention to wear of socket holes periodically,
and replace with a new one if needed.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Replacing supply cord
If the replacement of the supply cord is necessary, this
has to be done by the manufacturer of this agent in order
to avoid a safety hazard.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
