WOOD DRILLING�

For maximum performance, use high speed steel bits for

wood drilling.�

 Select normal drilling mode.�

 Begin drilling at a very low speed to prevent the bit from

slipping off the starting point. Increase the speed as the

drill bit bites into the material.�

 When drilling through holes, place a block of wood behind

the workpiece to prevent ragged or splintered edges on

the back side of the hole.�

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.�

OPERATION

 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 off-center or irregular-shaped holes.�

 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 carbide-tipped masonry

impact bits when drilling holes in brick, tile, concrete, etc.

 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,

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.

 When drilling hard, smooth surfaces, use a center punch

to mark the desired hole location. This will prevent the

drill bit from slipping off-center as the hole is started.

 When drilling metals, use a light oil on the drill bit to keep

it from overheating. The oil will prolong the life of the bit

and increase the drilling action.

 If the bit jams in the workpiece or if the drill stalls, stop

the tool immediately. Remove the bit from the workpiece

and determine the reason for jamming.
