5. When operating a power tool outside, use an

outdoor extension cord marked “W-A” or “W”.

These cords are rated for outdoor use and reduce

the risk of electrical shock.

6. Use only three-wire extension cords which

have three-prong grounding plugs and three-

pole receptacles which accept the machines

plug. Use of other extension cords will not ground

the tool and increase the risk of electrical shock.

7. Use proper extension cords. (See chart.) Insuf-

ficient conductor size will cause excessive voltage

drop, loss of power and overheating.

8. Before using, test the Ground Fault Circuit

Interrupter (GFCI) provided with the power cord

to insure it is operating correctly. GFCI reduces

the risk of electrical shock.

9. Extension cords are not recommended unless

they are plugged into a Ground Fault Circuit

Interrupter (GFCI) found in circuit boxes or out-

let receptacles. The GFCI on the machine power

cord will not prevent electrical shock from the

extension cords.

10. Keep all electric connections dry and off the

ground. Do not touch plug with wet hands.

Reduces the risk of electric shock.

Personal Safety

1. Stay alert, watch what you are doing and use

common sense when operating a power tool.

Do not use tool while tired or under the influ-

ence of drugs, alcohol, or medications. A

moment of inattention while operating power tools

may result in serious personal injury.

2. Dress properly. Do not wear loose clothing or

jewelry. Contain long hair. Keep your hair,

clothing, and gloves away from moving parts.

Loose clothes, jewelry, or long hair can be caught

in moving parts.

3. Avoid accidental starting. Be sure switch is

OFF before plugging in. Carrying tools with your

finger on the switch or plugging in tools that have

the switch ON invites accidents.

General Safety Information

WARNING! Read and understand all instructions.

Failure to follow all instructions listed

below may result in electric shock, fire,

and/or serious personal injury.

SAVE THESE INSTRUCTIONS!

Work Area Safety

1. Keep your work area clean and well lit. Cluttered

benches and dark areas invite accidents.

2. Do not operate power tools in explosive atmos-

pheres, such as in the presence of flammable

liquids, gases, or dust. Power tools create sparks

which may ignite the dust or fumes.

3. Keep bystanders, children, and visitors away

while operating a power tool. Distractions can

cause you to lose control.

Electrical Safety

1. Grounded tools must be plugged into an outlet,

properly installed and grounded in accordance

with all codes and ordinances. Never remove

the grounding prong or modify the plug in any

way. Do not use any adapter plugs. Check with

a qualified electrician if you are in doubt as to

whether the outlet is properly grounded. If the

tools should electrically malfunction or break down,

grounding provides a low resistance path to carry

electricity away from the user.

2. Avoid body contact with grounded surfaces

such as pipes, radiators, ranges and refrigera-

tors. There is an increased risk of electrical shock

if your body is grounded.

3. Don’t expose power tools to rain or wet condi-

tions. Water entering a power tool will increase the

risk of electrical shock.

4. Do not abuse cord. Never use the cord to carry

the tools or pull the plug from an outlet. Keep

cord away from heat, oil, sharp edges or moving

parts. Replace damaged cords immediately.

Damaged cords increase the risk of electrical shock.

4. Remove adjusting keys or switches before

turning the tool ON. A wrench or a key that is left

attached to a rotating part of the tool may result in

personal injury.

5. Do not overreach. Keep proper footing and

balance at all times. Proper footing and balance

enables better control of the tool in unexpected

situations.

6. Use safety equipment. Always wear eye pro-

tection. Dust mask, non-skid safety shoes, hard

hat, or hearing protection must be used for appro-

priate conditions.

7. Wear hearing protectors, ear plugs or muffs

when using tool. Noise level may affect hearing

with prolonged use.

Tool Use and Care

1. Use clamp or other practical way to secure and

support the workpiece to a stable platform.

Holding the work by hand or against your body is

unstable and may lead to loss of control.

2. Do not force tool. Use the correct tool for your

application. The correct tool will do the job better

and safer at the rate for which it is designed.

3. Do not use tool if switch does not turn it ON or

OFF. Any tool that cannot be controlled with the

switch is dangerous and must be repaired.

4. Disconnect the plug from the power source

before making any adjustments, changing

accessories, or storing the tool. Such preven-

tive safety measures reduce the risk of starting the

tool accidentally.

5. Store idle tools out of the reach of children and

other untrained persons. Tools are dangerous in

the hands of untrained users.

6. Maintain tools with care. Keep cutting tools

sharp and clean. Properly maintained tools with

sharp cutting edges are less likely to bind and are

easier to control.

7. Check for misalignment or binding of moving

parts, breakage of parts, and any other condi-

tion that may affect the tool's operation. If dam-

aged, have the tool serviced before using. Many

accidents are caused by poorly maintained tools.

8. Use only accessories that are recommended by

the manufacturer for your model. Accessories

that may be suitable for one tool may become haz-

ardous when used on another tool.

9. Keep handles dry and clean; free from oil and

grease. Allows for better control of the tool.

Service

1. Tool service must be performed only by quali-

fied repair personnel. Service or maintenance

performed by unqualified repair personnel could

result in injury.

2. When servicing a tool, use only identical

replacement parts. Follow instructions in the

Maintenance Section of this manual. Use of

unauthorized parts or failure to follow mainte-

nance instructions may create a risk of electrical

shock or injury.

WARNING

Do not attempt to start, detach or carry the tool

without the plunger engaged. The motor assem-

bly and the base could separate resulting in seri-

ous injury.

WARNING

Position electrical cord clear of the base of hole

saw to prevent cord damage and electrical shock.

12. Plug the hole cutting tool into the electrical outlet,

making sure to position the power cord along the

clear path. If the power cord does not reach the

outlet, use an extension cord in good condition.

(See page 2.)

WARNING

To avoid electric shock and electrical fires,

never use and extension cord that is damaged

or does not meet the following requirements:

• The cord has a three-prong plug similar to

shown in Electrical Safety.

• The cord is rated as “W” or “W-A” if being used

outdoor.

• The cord has a wire thickness gauge that does

not exceed 14 AWG if shorter than 30 feet or

12 AWG if 30 feet or longer. If the cord is too

long or if the wire thickness is too small, the

cord may overheat, melting the cord’s insula-

tion or causing nearby objects to ignite.

Operating Instructions

Model HC-300

WARNING

Do not use a hole cutting tool without proper

eye protection.

1. The Model HC-300 is turned on by depressing an

ON/OFF switch located on the side of the unit

behind the feed wheel. (Figure 20)

2. Feed the hole saw into the pipe by turning feed

wheel handle counterclockwise using moderate

force so as to not overload the motor.

WARNING

Keep fingers and hands away from the saw

blade. Do not reach across the hole saw or wear

loose gloves or clothing that may become entan-

gled and cause serious injury.

3. Rotate feed handle counter-clockwise to apply

downward pressure on the hole saw.

WARNING

Forcing hole saw into pipe will not reduce cut-

ting time. Therefore, do not overfeed saw while

cutting. Doing so will result in premature saw

failure or possible serious injury.

4. After completing the hole cut, retract the saw from

the pipe by turning the feed wheel clockwise.

NOTE! When branching off an existing pipe system, use

a hole saw with the

″ pilot drill. The pilot drill

helps retain the pipe slug in the hole saw.

5. Turn unit OFF by depressing ON/OFF switch to the

OFF position.

6. Remove unit by:

A. Unclamping entire assembly or

B. Retrieving motor assembly by pulling plunger

and then unclamping the base.

7. Brush away all metal chips created by the hole saw

from the area around the hole.

NOTE! The flat area with the RIDGID lettering in the

back of the base and the machined areas on the

side of the posts are designed for level mount-

ing. They are useful when series of holes need to

be aligned.
