MASONRY DRILLING
For maximum performance, use carbide-tipped masonry
impact bits when drilling holes in brick, tile, concrete, etc.
 Slide adjustment button on hammer drill left for
hammer mode.
 Apply light pressure and medium speed for best results
in brick.
WARNING:
When servicing, use only identical
Craftsman replacement parts. Use of any other part
may create a hazard or cause product damage.
WARNING:
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.
WARNING:
To avoid serious personal injury, always
remove the battery pack from the tool when cleaning
or performing any maintenance.
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. Chemi-
cals can damage, weaken or destroy plastic which
may 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. Lithium-ion and
nickel-cadmium batteries must be recycled or dis-
posed 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.
OPERATION
 Apply additional pressure for hard materials such as
concrete.
 When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure. Begin drilling
at a very low speed to prevent the bit from slipping off
the starting point.

MAINTENANCE

CHUCK REMOVAL
See Figures 17 - 19, page iii.
The chuck may be removed and replaced by a new one.
 Lock the switch trigger by placing the direction of rota-
tion 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 counter-
clockwise 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.
To tighten:
 Lock the switch trigger by placing the direction of rota-
tion 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.
 Open the chuck jaws and remove the hex key.
 Tighten the chuck screw.
