Motor Brushes
DEWALT uses an advanced brush system which automatically stops
the drill when the brushes wear out. This prevents serious damage to
the motor. New brush assemblies are available at authorized D
EWALT
service centers. Always use identical replacement parts.
Lubrication
Your tool was properly lubricated before leaving the factory. In from
two to six months, depending upon use, take or send your tool to a
D
EWALT Service Center or other qualified service organization for a
complete cleaning, inspection and relubrication.
Tools used constantly on production or heavy duty jobs or exposed
to heat may require more frequent lubrication. Tools “out of service”
for long periods should be relubricated before being put back into
service.

WA R N IN G : Blow dirt and dust out of all air vents with clean, dry air
at least once a week. To minimize the risk of eye injury, always wear
ANSI Z87.1 approved eye protection when performing this.

REMOVAL OF KEYED CHUCK (FIG. 9)
Remove the left-handed clutch screw using a T25 torx wrench,
rotating clockwise to loosen.
Tighten the chuck around the shorter
end of a hex wrench (not supplied) of 3/8" (10 mm) size. With the tool
braced securely, use a soft hammer and strike the hex wrench sharply
in the counterclockwise direction when viewed from the front of the
tool. This will loosen the chuck
so that it can be removed by hand.
KEYED CHUCK INSTALLATION (FIG. 10)
Screw the chuck on by hand as far as it will go. Insert the shorter end
of a hex wrench (not supplied) of 3/8" (10 mm) size and strike it in
the clockwise direction with a soft hammer.
Reinstall the left handed
