MAINTENANCE WARNING: When servicing use only identical RIDGID replacement parts. Use of any other parts may create a hazard or cause product damage. CHUCK JAWS MALLET WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask. 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. HEX KEY Fig. 9 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. SCREWDRIVER Electric tools used on fiberglass material, wallboard, spackling 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 extremely 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 lubrication is required. CHUCK REMOVAL See Figures 9 - 11. 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. MALLET Fig. 10 HEX KEY Fig. 11  Insert hex key in the chuck and tighten chuck jaws securely.  Tap sharply with a mallet in a counterclockwise direction. This will loosen chuck on the spindle.
