Maintenance - Craftsman 315.115760 Operator's Manual

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. Nickel-cadmium
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.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure
to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust
masks that are specially designed to filter out microscopic particles.

MAINTENANCE

CHUCK REMOVAL
See Figures 8-10, page ii.
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. Remove
the chuck screw by turning it in a clockwise direction.
NOTE: The screw has left hand threads.
 Insert the hex key in 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 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.
NOTE: The chuck screw has left hand threads.
