WARNING
Use only sockets and other
accessories specifi cally designed for use on
impact wrenches and drivers. Other sockets
and accessories might shatter or break caus-
ing injury.
Attaching and Removing Accessories
(Cat. No. 9078-20)
This impact wrench is intended only for use with
sockets designed for impact wrenches and that
have a 3/4" square drive. Other sockets could
shatter or break, causing injury.
1. To attach a socket or other accessory, push
the accessory onto the drive shank until it
snaps into place.
2. To remove the accessory, pull it off the drive
shank.
Attaching and Removing Accessories
(Cat. No. 9079-20)
This impact wrench is intended only for use with
sockets designed for impact wrenches and that
have a 1/2" square drive. Other sockets could
shatter or break, causing injury.
1. To attach a socket or other accessory, 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.
2. To remove the accessory, insert a nail or other
thin object into the hole in the accessory and
press the detent pin in. Pull the accessory off
the drive shank.
Attaching and Removing Accessories
(Cat. No. 9098-23, 9099-20, or using the Quick
Change 1/2" Square Drive to 7/16" Hex Adapter)
Cat. No. 9099-20 and accessory Cat. No. 48-66-
0061 are intended for use with accessories with a
7/16" Hex Quick Change shank. Cat. No. 9098-23
is intended for use with accessories with a 5/8"
Hex Quick Change shank. Both Hex Quick Change
shanks have a ball-retainer groove. They are not
intended for use with Hex Shank Bit Extensions.

OPERATION
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side
shields. Unplug the tool before changing ac-
cessories or making adjustments.
Using the Forward/Reverse Switch
The forward/reverse switch may be set to three po-
sitions: forward, reverse and lock. Due to a lockout
mechanism, the forward/reverse switch can only be
adjusted when the trigger is not depressed. Always
allow the motor to come to a complete stop before
using the forward/reverse switch.

Reverse
1. For forward (clockwise) rotation, push the
forward/reverse switch in the direction shown.
Check the direction of rotation before use.
2. For reverse (counterclockwise) rotation, 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 forward/reverse switch is in the
locked position. Always lock the trigger or remove
the battery pack before performing maintenance,
changing accessories, storing the tool and any
time the tool is not in use.
WARNING
To reduce the risk of injury,
keep hands and away from the bit and all
moving parts.
WARNING
To reduce the risk of explo-
sion, electric shock and property damage,
always check the work area for hidden pipes
and wires before drilling.
WARNING
To reduce the risk of injury,
only grasp tool by handle and red insulated
surfaces (Fig. 4). Do not hold gray gear case
when impacting or drilling.

Starting, Stopping and Controlling Speed
Fig. 4
This impact wrench 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 fasteners
are too tight, reduce the impacting time. If they are
not tight enough, increase the impacting time.
Impacting for two seconds is generally suffi cient for
a 3/8" bolt and one second for a 5/16" bolt. How-
ever, 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. However,
if rust or corrosion causes seizing, more torque may
be required.
On light gasket jobs, run each fastener down to a
relatively light torque and use a hand torque wrench
for fi nal tightening.
