Usage
Your impact tool can generate the following
maximumtorque:
Mode Ft.-Lbs. In.-Lbs. Nm
1 20 240 27
2 125 1500 170
3 152 1825 205

CAUTION: Ensure fastener and/or system will
withstand the level of torque generated by the tool.
Excessive torque may cause breakage and possible
personalinjury.
1. Place the accessory on the fastener head. Keep the tool
pointed straight at thefastener.
2. Press switch to start operation. Release switch to stop
operation. Always check torque with a torque wrench,
as the fastening torque is affected by many factors
including the following:
• Voltage: Low voltage, due to a nearly discharged
battery, will reduce fasteningtorque.
• Accessory size: Failure to use the correct
accessory size will cause a reduction in
fasteningtorque.
• Bolt size: Larger bolt diameters generally require
higher fastening torque. Fastening torque
will also vary according to length, grade, and
torquecoefficient.
• Bolt: Ensure that all threads are free of rust and
other debris to allow proper fasteningtorque.
• Material: The type of material and surface finish
of the material will affect fasteningtorque.
• Fastening time: Longer fasten ing time results
in increased fastening torque. Using a longer
fastening time than recommended could
cause the fasteners to be overstressed, stripped
ordamaged.
