the tool will drive for-
ward at a reduced RPM
until the torque is
achieved. In reverse the
tool will operate at full
RPM to remove fasten-
ers at full torque.
Using the Control Switch
The control switch may be set to three positions:
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.

PUSH TO CENTER TO LOCK
1. For
forward
(clockwise) rotation, push the control
switch in the direction shown. Check the direction
of rotation before use.
2. For
reverse
(counterclockwise) rotation, push the
control switch in the direction shown. Check the
direction of rotation before use.
3. To
lock
the trigger, push the control switch to the
center position. The trigger will not work when the
control switch is in the locked position.
Always remove the battery pack before performing
maintenance, changing accessories, storing the
tool and any time the tool is not in use.
Starting, Stopping and Controlling Speed
These tools may be operated at any speed from 0
to full speed.
1. To
start
the tool, pull the trigger.
NOTE:
An LED is turned on when the trigger is
pulled.
2. To
vary
the driving speed, simply increase or
decrease pressure on the trigger. The further the
trigger is pulled, the greater the speed.
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.
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 final tightening.

1. Use only the appropriate size Square Drive Sockets.
2. To attach a socket, align the accessory with the
anvil and push it firmly over the retaining ring.
3. To remove the accessory, pull the accessory off
the anvil.
1/2" Pin Detent
(Cat. No. 2555P-20)
