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.

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

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.

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.
