direction of the tool and also serves as a lock-off button.
To select forward rotation, release the trigger switch and
depress the forward/reverse control button on the right side
of the tool.
To select reverse, release the trigger switch and depress the
forward/reverse control button on the left side of the tool.
The center position of the control button locks the tool in
the off position. When changing the position of the control
button, be sure the trigger is released.
NoTE: The first time the tool is run after changing the
direction of rotation, you may hear a click on start up. This is
normal and does not indicate a problem.

Usage
Your impact tool can generate the following maximum
torque:
Cat # Ft.-lbs.
DCF886 125

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.
