Usage
Your impact tool generates the following output torque:
Cat # Ft.-Lbs.
DCF813 96
DCF815 79
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 socket on the fastener head. Keep the tool pointed
straight at the fastener.
2. Press switch to start 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.
• Socket size: Failure to use the correct socket 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.
