MAINTENANCE
WARNING: When servicing, use only identical
replacement parts. Use of any other parts could
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.
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 by a qualified service dealer.
CHUCK REMOVAL
See Figures 9 - 11, page ii.
The chuck may be removed and replaced by a new one.

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.

direction. This will loosen the screw in the chuck for

a wobble. Also, the chuck screw may become loose,

rotation selector in the center position.
Open the chuck jaws.
Insert the hex key into the chuck and tighten the chuck
