Maintenance - DeWalt DCF886-XE Instruction Manual

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.
Worklights (Fig. 2)
There are three worklights (G) located around the chuck collar (C). The worklights
are activated when the trigger switch is depressed. When the trigger is released, the
worklight will stay illuminated for up to 20 seconds. If the trigger switch remains
depressed, the worklights will remain on.
NOTE: The worklights are for lighting the immediate work surface and are not
intended to be used as a flashlight.
Quick-Release Chuck (Fig. 2, 6, 7)
WARNING: Use only impact accessories. Non-impact accessories may break and
cause a hazardous condition. Inspect accessory prior to use to ensure that it con tains
no cracks.
NOTE: The chuck accepts 6.35 mm (1/4") hex accessories and 25.4 mm (1") bit tips
only.
Place the forward/reverse button (B) in the lock-off (center) position or remove battery
pack before changing accessories.

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

MAINTENANCE

WARNING: To reduce the risk of serious personal injury, turn the tool off and
disconnect the battery pack before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can cause injury.
