handle 6 .
Usage (Fig. A)

CAUTION: Ensure fastener and/or system will
withstand the level of torque generated by the tool.
Excessive torque may cause breakage and possible
personal injury.
1. Place the accessory on the fastener head. Keep the tool
pointed straight at the fastener.
2. Press variable speed trigger switch
Release variable speed trigger switch to stop operation.
Always check torque with a torque wrench, as the
fastening torque is affected by many factors including
the following:
‑ Voltage: Low voltage, due to a nearly discharged
battery, will reduce fastening torque.
Accessory size: Failure to use the correct accessory
‑
size will cause a reduction in fastening torque.
‑ Bolt size: Larger bolt diameters generally require
higher fastening torque. Fastening torque
will also vary according to length, grade, and
torque coefficient.
Bolt: Ensure that all threads are free of rust and other
‑
debris to allow proper fastening torque.
‑ Material: The type of material and surface finish of
the material will affect fastening torque.
Fastening time: Longer fasten ing time results in
‑
increased fastening torque. Using a longer fastening
time than recommended could cause the fasteners
to be overstressed, stripped or damaged.
