forward, reverse and lock. Due to a lockout mecha-
nism, the control switch can only be adjusted when
the ON/OFF switch is not pressed. Always allow the
motor to come to a complete stop before using the
control switch.

2. To vary the driving speed, increase or decrease
pressure on the trigger. The further the trigger is

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.
WARNING
Always remove battery pack before
changing or removing accessories.
To insert the battery, slide the pack into the body
of the tool. Make sure it latches securely into place.
