UsingControlSwitch
The control switch may be set to three positions: for-
ward, reverse and lock. Due to a lockout mechanism,
the control switch can only be adjusted when the trig-
ger is not pressed. Always allow the motor to come
to a complete stop before using the control switch.
1. For forward(clockwise) rotation, push the con-
trol switch from the right side of the tool. Check
the direction of rotation before use.
2. For reverse (counterclockwise) rotation, push
the control switch from the left side of the tool.
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 perform-
ing maintenance, changing accessories, storing
the tool and any time the tool is not in use.
Starting,StoppingandControllingSpeed
These tools may be operated at any speed from
0 to full speed.
1. To start the tool, pull the trigger.
2. To varythe driving speed, 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.
ImpactingTechniques
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 fasten-
ers 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 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 nal tightening.
