Fastening

WARNING: 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 forward/reverse switch
Always check torque with a torque wrench, as the
fastening torque is affected by many factors including
the following:
Voltage: Low voltage, due to generator or long
extension cord, 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 fastening time results in
increased fastening torque. Using a longer fastening
time than recommended could cause the fasteners to
be overstressed, stripped or damaged.
Capacity
