Push in the release buttons and remove the bat-
tery pack. 

Battery pack can be inserted into the tool in two 
ways.

1.  For working in restricted spaces.

 

Insert the battery pack from the front by pressing 
in the release buttons and sliding battery pack 
into the body of the tool. Insert the battery pack 
until clamp engages. 

2.  For optimum weight distribution and balance.

 

Insert the battery pack from the back by press-
ing in the release buttons and sliding the battery 
pack into the body of the tool. Insert the battery 
pack until clamp engages. 

These impact wrenches are intended only for use 
with sockets designed for impact wrenches 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 

accessory with the drive shank and push it fi rmly 
over the retaining ring.

2.  To remove the accessory, pull the accessory off 

the drive shank.

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.

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 pressed. Always 
allow the motor to come to a complete stop before 
using the forward/reverse switch.

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 remove the battery 
pack before performing maintenance, chang-
ing accessories, storing the tool and any time 
the tool is not in use.

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 and the 

electric brake stops the tool instantly.

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.

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.

On light gasket jobs, run each fastener down to a 
relatively light torque and use a hand torque wrench 
for fi nal tightening.
