causing injury.
Attaching and Removing Accessories
These tools are intended only for use with accesso-
ries designed for impact wrenches and drivers.Other
sockets could shatter or break, causing injury.
Cat. No. 2662-20
1. Use only the appropriate size Square
Drive Sockets.
2. To attach a socket, align the hole in
the accessory with the detent pin on
the drive shank. Hold the detent pin
in while pushing the socket onto the
drive shank. The detent pin will snap
into place in the hole to secure the
socket.
3. To remove the socket, insert a nail or
other thin object into the hole in the
accessory and press in the detent pin.
Pull the accessory off the drive shank.

drive shank and push it firmly over the retaining
ring.
3. To remove the accessory, pull the accessory off
the drive shank.

the accessory shank. Release the ring. It may be
necessary to pull the bit out slightly to engage the
holding mechanism.
2. To remove the accessory, pull out the ring and

OPERATION

To reduce the risk of injury, always
WARNING
wear proper eye protection marked
to comply with ANSI Z87.1.
When working in dusty situations, wear appro-
priate respiratory protection or use an OSHA
compliant dust extraction solution.
Always remove battery pack before changing
or removing accessories. Only use accessories
specifically recommended for this tool. Others
may be hazardous.
Keep hands away from all moving parts.
Using Control Switch
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 control
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 performing
maintenance or changing accessories. Always
lock the trigger or remove the battery pack before
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, grasp the handle firmly and pull
the trigger.
2. To vary the 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. Ensure the
tool has come to a complete stop before laying
the tool down.
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 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.
