Attaching and Removing Accessories
This impact driver is intended for use with drill and
driver bits.
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 Recharge only with the
charger specifi ed for the battery. For specifi c
charging instructions, read the operator’s
manual supplied with your charger and bat-
tery.
WARNING Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
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.
Inserting/Removing the Battery
To remove the battery, push in the release buttons
and pull the battery pack away from the tool.

the control switch in the direction shown.
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 posi-
tion.
Always lock the trigger or remove the battery
pack before performing maintenance, chang-
ing accessories, storing the tool and any time

Fuel Gauge
To determine the amount of charge left in the bat-
tery, pull the trigger. The Fuel Gauge will light up
for 2-3 seconds.
To signal the end of charge, 1 light on the fuel gauge
will fl ash for 2-3 seconds.
Using Control Switch
The control switch may be set to three positions:
forward, reverse and lock. Due to a lockout mecha-
nism, the control switch can only be adjusted when
the ON/OFF switch is not pressed. Always allow
the motor to come to a complete stop before using
the control switch.
PUSH TO CENTER TO LOCK
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.
NOTE: An LED is turned on when the trigger
is pulled.
2. To vary the driving speed, simply 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 impact-
ing 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 fi nal tightening.
