control switch.
For forward (clockwise) rotation,
push the control switch in the CENTER TO LOCK
direction shown. Check the di-
rection of rotation before use.
Forward

rotation, push the control switch
in the direction shown. Check the
direction of rotation before use.

pressure on the trigger. The further the trigger is
pulled, the greater the speed, up to the maximum
speed set by the speed control.
3. To stop the tool, release the trigger and the electric
brake stops the tool instantly.
Impacting Techniques
The longer a bolt, screw, or nut is impacted, the
tighter it will become. To help prevent damaging the
fasteners or workpieces, avoid excessive impact-
ing. Be particularly careful when impacting smaller
fasteners because they require less impacting to
reach optimum torque.
Practice with various fasteners, noting the length of
time required to reach the desired torque. Check the
tightness with a hand-torque wrench. If the fasteners
are too tight, reduce the impacting time. If they are
not tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under
the head of the fastener affects the degree of tight-
ness.
4
The torque required to loosen a fastener averages
75% to 80% of the tightening torque, depending on
the condition of the contacting surfaces.
On light gasket jobs, run each fastener down to a
relatively light torque and use a hand torque wrench
for fi nal tightening.
