OPERATING INSTRUCTIONS
LOW-VOLTAGE CUT-OUT
The battery pack used on this tool is fitted with a low-voltage cut-out feature within
the circuitry. The low-voltage cut-out feature operates when the voltage drops below
a pre-set value. This feature automatically stops the tool from operating. When this
condition occurs you will need to either insert another battery pack into the tool or
recharge the existing battery pack.
TIGHTENING FASTENERS
Before starting your job, always perform a test operation to determine the proper
fastening time for your bolt or nut.

Practice with various fasteners, noting the length of time required to reach the desired
torque. Check the tightness with a torque wrench. If the fasteners are too tight, reduce
the impacting time. If they are not tight enough, increase the impacting time.

•Socket.Failuretousethecorrectsizesocketwillcauseareductioninthefastening
torque. A worn socket (wear on the hex end or square end) will cause a reduction in
the fastening torque.

or freezer. To reduce the temperature of the cells remove the
battery pack from the tool and place the battery pack in a free air
environment, out of direct sunlight or any other heat source.
NOTE:
NOTE: Attempting to restart the tool without either recharging
the battery or installing another battery (with charge) will lead to
tool restarting and then stopping again, after only a few seconds of
operation.
NOTE:
The torque that is required to loosen a fastener averages 75% to 80%
of the tightening torque, depending on the condition of the contacting
surfaces. However, if rust or corrosion causes seizing, more torque may
be required.
