Warning
accessories specifically designed for use on
impact wrenches and drivers. Other sockets
and accessories might shatter or break caus-
ing injury.
Attaching and Removing Accessories
These tools are intended only for use with acces-
sories 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.
Cat. No. 2663-20, 2664-20
1. Use only the appropriate size Square Drive Sockets.
2. To attach a socket, align the accessory with the
drive shank and push it firmly over the retaining ring.
3. To remove the accessory, pull the accessory off
the drive shank.
Cat. No. 2665-20
This driver is intended for use with drill and driver
bits with a 7/16" hex shank and ball detent recess.
1. To attach an accessory, pull the ring out and
insert 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
remove the accessory. Release the ring.

Warning
pack before changing or removing accesso-
ries. Only use accessories specifically recom-
mended for this tool. Others may be hazardous.
Warning
wear safety goggles or glasses with side shields.
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 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, 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, 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.
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 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 final tightening.
