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.

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.

Using the Drive Control  
The drive control button is used to adjust the torque, 
rotation speed (RPM), and impact speed (IPM) for 
the application (see Specifi cations chart for RPM 
and IPM).
To select the drive control mode:
1. Pull and release the trigger to turn on the tool. 

The current mode indicator is lit.

2. Press the drive control button 

 to cycle through 

the 3 modes. When the desired mode indiator 
is lit, begin work.

Using the 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.
1. For  forward  (clockwise) rotation, push the 

control switch in the direction shown. Check the 
direction of rotation before use.

2. For  reverse (counterclockwise) rotation, push 

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 position. 

  Always remove the battery pack before perform-

ing maintenance, changing accessories, storing 
the tool and any time the tool is not in use.
