OPERATION
WARNING!
To reduce the risk of injury, wear safety goggles or glasses with side shields.
WARNING!
To reduce the risk of injury, only grasp tool by handle and black insulated surfaces . Do not hold gray gear case when impacting or drilling.
Starting and Stopping the Tool (Fig. 2)
This impact wrench is equipped with a rocker switch that offers both forward and reverse rotation.
Fig. 2
Rocker switch
1.For forward (clockwise) rotation, pull the lower portion of the switch.
2.For reverse (counterclockwise) rotation, pull the upper portion of the switch.
NOTE: To prevent damage to the motor and internal mechanism, allow the motor to stop completely before switching from forward to reverse or from reverse to forward.
WARNING!
To reduce the risk of injury, keep hands and cord away from the bit and all moving parts.
WARNING!
To reduce the risk of explosion, electric shock and property damage, always check the work area for hidden pipes and wires before drilling.
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 impacting. Be particularly careful when impacting smaller fasteners be- cause 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
Impacting for two seconds is generally sufficient for a 3/8" bolt and one second for a 5/16" bolt. However, 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.
