Voltage: Low voltage due to a nearly discharged battery will reduce the fastening
torque.
Socket Size: Failure to use the correct socket size will cause a reduction in fastening
torque.
Variable Speed Trigger Switch: Operating the tool at a reduced speed will reduce the
fastening torque.
Bolt Size: Larger bolt diameters generally require higher fastening torque. Fastening
torque will also vary according to length, grade, and torque coefficient.
Material: The type of material and surface finish of the material will affect fastening
torque.
Fastening Time: Longer fastening time results in increased fastening torque. Using a
longer fastening time than recommended could cause the screws to be overstressed,
stripped or damaged.
NOTE
Continuous use in variable speed range is not recommended. It may damage the switch and
should be avoided.
NOTE
When change the position of the control button, making sure the variable speed switch is
released.
NOTE
The first time the tool is run after changing the direction of rotation, you may hear a click
on start up. This is normal and does not indicate a problem.
WARNING
NOTE
This tool is lubricated before it leaves the factory. This lubrication should last for the life of
the tool. No further lubrication is required.
CLEANING
With the motor running, blow dirt and dust out of all air vents with dry air at least once
a week. Wear safety glasses when performing this. Exterior plastic parts may be
cleaned a damp cloth and mild detergent. Although these parts are highly solvent
resistant, NEVER use solvent.
