Worklights (fig. 1)
There are three worklights (g) located around the
chuck collar (c). The worklights will be activated
when the trigger switch is squeezed.
When the trigger is released the worklight will stay
illuminated for up to 20 seconds.
NOTE: The worklights are for lighting the immediate
work surface and are not intended to be used as a
flashlight.
Quick-Release Chuck (fig. 1, 3)
DCF835, DCF885
NOTE: The chuck accepts 6.35 mm (1/4") hex
accessories and 25.4 mm (1") bit tips only. Using
25.4 mm (1") bits allows better access in tight
spaces.
Place the forward/reverse button (b) in the locked
off (center) position or remove battery pack before
changing accessories.
To install an accessory, push accessory to fully insert
into chuck. The chuck collar does not need to be
pulled up to lock accessory in place.
To remove an accessory, pull the chuck collar away
from the front of the tool. Remove the accessory
and release the collar.
Anvil with Detent Pin (Fig. 1)
DCF830, DCF880
Place the switch in the locked off (center) position or
remove battery pack before changing accessories.
To install a socket on the anvil, align the hole in the
side of the socket with the detent pin (m) on the
anvil (l). Press the socket on until the detent pin
engages in the hole. Depression of detent pin may
be necessary to aid installation of socket.
To remove a socket, depress the detent pin through
the hole and pull the socket off.
WARNING: Use only impact sockets.
Non-impact sockets may break and
cause a hazardous condition. Inspect
sock et prior to use to ensure that it
contains no cracks.
Usage
Your impact tool generates the following maximum

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. 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 recom mended
could cause the fasteners to be overstressed,
stripped or damaged.
MAINTENANCE
Your D
WALT power tool has been designed to
e
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
WARNING: To reduce the risk
of serious personal injury, place
the forward/reverse button in
the lock-off position or turn tool
off and disconnect battery pack
before making any adjustments or
removing/installing attachments or
accessories. An accidental start-up
can cause injury.
The charger and battery pack are not serviceable.
There are no serviceable parts inside.
Lubrication
