OPERATION
METAL DRILLING�
For maximum performance, use high speed steel bits for metal or steel drilling.
Select normal drilling mode.
Begin drilling at a very low speed to prevent the bit from slipping off the starting point.�
Maintain a speed and pressure which allows cutting without overheating the bit. Applying too much pressure will:
•Overheat the drill;
•Wear the bearings;
•Bend or burn bits; and
•Produce
When drilling large holes in metal, start with a small bit, then finish with a larger bit. Also, lubricate the bit with oil to improve drilling action and increase bit life.
MASONRY DRILLING
For maximum performance, use
Slide adjustment button on hammer drill left for hammer mode.�
Apply light pressure and medium speed for best results in brick.�
Apply additional pressure for hard materials such as concrete.�
When drilling holes in tile, practice on a scrap piece to determine the best speed and pressure. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.�
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 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.
WARNING:
Do not at any time let brake fluids, gasoline,
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 product for extended work on these types of materials. However, if you do work with any of these ma- terials, 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.
