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.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to acceler-
ated wear and possible premature failure because the fi-
berglass chips and grindings are highly abrasive to bear-
ings, brushes, commutators, etc. Consequently, we do not
recommended using this product for extended work on
these types of materials. However, if you do work with any
of these materials, it is extremely important to clean the
product using compressed air.
LUBRICATION
All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
lubrication is required.
POWER SUPPLY CORD REPLACEMENT
If replacement of the power supply cord is necessary, this
must be done by an authorized service center in order to
avoid a safety hazard.
CHUCK REMOVAL
See Figures 10 - 12, page 12.
The chuck may be removed and replaced with a new one.
Unplug the drill.
Open chuck jaws using the provided chuck key.
Insert a 5/16 inch 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 di-
rection. This will loosen the screw in the chuck for easy
removal.
Open chuck jaws and remove hex key. Remove the chuck
screw with a screwdriver by turning it in a clockwise di-
rection.
NOTE: The 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 counterclock-
wise 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 devel-
op a wobble. Also, the chuck screw may become loose,
causing the chuck jaws to bind and prevent them from
closing.

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
