MAINTENANCE
WARNING:
When servicing use only identical RIDGID
replacement parts. Use of any other parts may
create a hazard or cause product damage.
WARNING:
Always wear eye protection 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 may
result in serious personal injury.
Electric tools used on fiberglass material, wallboard, spack-
ling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommended
using this tool for extended work on these types of materials.
However, if you do work with any of these materials, it is ex-
tremely important to clean the tool using compressed air.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrica-
tion is required.
CHUCK REMOVAL
See Figures 14 - 16, page 16.
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 (8 mm) 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 chuck jaws and remove hex key. Remove the chuck
screw by turning it in a clockwise direction.
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
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, caus-
ing the chuck jaws to bind and prevent them from closing.
To tighten:
Unplug the drill.
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.
