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
3
to start operation.
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.
required) start a slow controlled impact to ensure the head
ends perfectlyflush.


WARNING: To reduce the risk of serious personal
injury, ensure the screw holding the belt hook
issecure.
NOTE: Bit clip and belt hook cannot be used with the
lanyard-ready attachment kitinstalled.
