Usage
Your impact tool generates the following maximum torque:
Cat # nm
DCF887 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 into the chuck. Keep the tool pointed
straight at the work piece.
2. Press switch to start operation. Release the 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.
- 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.
- 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.
