To reduce the risk of injury, wear
safety goggles or glasses with
side shields.
Using the Forward/Reverse Switch
(Fig. 6)
The forward/reverse switch may be set to
three positions: forward, reverse and lock.
Due to a lockout mechanism, the forward/
reverse switch can only be adjusted when
the trigger is not pressed. Always allow
the motor to come to a complete stop be-
fore using the forward/reverse switch.
Fig. 6
1.
For forward (clockwise) rotation,
push the forward/reverse switch in
the direction shown. Check the direc-
tion of rotation before use.
2.
For reverse (counterclockwise) ro-
tation, push the forward/reverse
switch in the direction shown. Check
the direction of rotation before use.
3.
To lock the trigger, push the forward/
reverse switch to the center position.
The trigger will not work when the for-
ward/reverse switch is in the locked
position. Always lock the trigger or
remove the battery pack before per-
forming maintenance, changing acces-
sories, storing the tool and any time
the tool is not in use.

OPERATION
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.
2.
To vary the driving speed, simply in-
crease 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 impacting. 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 de-
sired 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 impact-
ing time.
Impacting for two seconds is generally
sufficient for a 3/8" bolt and one second
for a 5/16" bolt. However, oil, dirt, rust or
other matter on the threads or under the
head of the fastener affects the degree of
tightness.
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.
