WARNING:
When servicing, use only identical
Craftsman replacement parts. Use of any other part
can create a hazard or cause product damage.

Always wear eye protection with side
shields marked to comply with ANSI Z87.1. Failure to
do so could result in objects being thrown into your
eyes resulting in possible serious injury.

To avoid serious personal injury,
always remove the battery pack from the tool when
cleaning, performing any maintenance, or when

GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids,
gasoline, petroleum-based products, penetrating
oils, etc., come in contact with plastic parts.
Chemicals can damage, weaken or destroy plastic
which could result in serious personal injury.
Only the parts shown on the parts list are intended to
be repaired or replaced by the customer. All other parts
should be replaced at a Sears Service Center.
BATTERY PACK REMOVAL AND PREPARATION
FOR RECYCLING
WARNING:
Upon removal, cover the battery pack's
terminals with heavy-duty adhesive tape. Do not
attempt to destroy or disassemble battery pack or
remove any of its components. Batteries must be
recycled or disposed of properly. Also, never touch
both terminals with metal objects and/or body parts
as short circuit may result. Keep away from children.
Failure to comply with these warnings could result in
fire and/or serious injury.

CHUCK REMOVAL
See Figures 12 - 14, page ii.
The chuck may be removed and replaced by a new one.
 Lock the switch trigger by placing the direction of
rotation selector in center position.
 Insert a 5/16 in. or larger hex key into the chuck of the
drill and tighten the chuck jaws securely.
 Tap the hex key sharply with a mallet in a clockwise
direction. This will loosen the screw in the chuck for
easy removal.
 Open the chuck jaws and remove the hex key.
 Using a screwdriver, remove the chuck screw by
turning it in a clockwise direction.
NOTE: The chuck screw has left hand threads.
 Insert the hex key into the chuck and tighten the
chuck jaws securely. Tap sharply with a mallet in a
counterclockwise direction. This will loosen the chuck
on the spindle. It can now be unscrewed by hand.
TO RETIGHTEN A LOOSE CHUCK
The chuck may become loose on the spindle and develop
a wobble. Also, the chuck screw may become loose,
causing the chuck jaws to bind and prevent them from
closing.

rotation selector in the center position.
 Open the chuck jaws.
 Insert the hex key into the chuck and tighten the chuck
jaws securely. Tap the hex key sharply with a mallet in
a clockwise direction. This will tighten the chuck on the
spindle.
