General Safety Rules*
WARNING
Read and understand all instructions. Failure to follow all in-
structions listed below may result in electric shock, fire,
and/or serious injury.
SAVE THESE INSTRUCTIONS!
Work Area
•Keep work area clean and well lit. Cluttered benches
and dark areas invite accidents.
•Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable li-
quids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
•Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
Electrical Safety
•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 out-
let is properly grounded. If the tool should electrically
malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user.
•Avoid body contact with grounded surfaces such
as pipes, radiators, ranges and refrigerators. There
is an increased risk of electric shock if your body is
grounded.
•Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the risk
of electric shock.
•Do not abuse the cord. Never use the cord to carry
the tool 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 electric shock.
•When operating a power tool outside, use an out-
door extension cord marked “W-A” or “W”. These

Personal Safety
•Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not
use a tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inat-
tention while operating power tools may result in seri-
ous personal injury.
•Dress properly. Do not wear loose clothing or jew-
elry. 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.
•Avoid accidental starting. Be sure switch is OFF be-
fore plugging in. Carrying power tools with your finger
on the switch or plugging in power tools that have the
switch ON invites accidents.
•Remove adjusting keys or wrenches before turning
the tool ON. A wrench or a key left attached to a rotat-
ing part of the power tool may result in personal injury.
•Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables bet-
ter control of the tool in unexpected situations.
•Use safety equipment. Always wear eye protec-
tion. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used for
appropriate conditions will reduce personal injuries.
Tool Use and Care
•Use clamps 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.
•Do not force the tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it was designed.
•Do not use the power tool if the switch does not turn
it ON and OFF. Any tool that cannot be controlled with
the switch is dangerous and must be repaired.
•Disconnect the plug from the power source be-
fore making any adjustments, changing accessor-
ies, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool
accidentally.
•Store idle tools out of the reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
HC-450/HC-300 Hole Cutting Tools
•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.
•Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may
affect the tool’s operation. If damaged, have the
tool serviced before using. Many accidents are
caused by poorly maintained tools.
•Use only accessories that are recommended by the
manufacturer for your model. Accessories that may
be suitable for one tool, may become hazardous when
used on another tool.
Service
•Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
•When servicing a tool, use only identical replace-
ment parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or
failure to follow Maintenance Instructions may create a
risk of electrical shock or injury.

Pre-Operation Inspection
WARNING
Before each use, inspect your Hole Cutting Tool
and correct any problems to reduce the risk of se-
rious injury from electric shock and other causes and
prevent tool damage.
1. Make sure that the Hole Cutting Tool is unplugged
and the ON/OFF switch is in the OFF position.
2. Clean any oil, grease or dirt from the tool, including
the handles and controls. This aids inspection and
helps prevent the tool or control from slipping from
your grip.
3. Inspect the Hole Cutting Tool for the following items:
• Inspect the power cord, Ground Fault Circuit Inter-
rupter (GFCI) and plug for damage or modification.
• Proper assembly and completeness.
• Broken, worn, missing, mis-aligned or binding parts.
Make sure that the motor assembly moves smooth-
ly and freely up and down the posts of the base as-
sembly. Confirm that the chain and swivel handle
move freely. On the HC-300, confirm that the plung-
er pin functions properly and retains the motor as-
sembly to the base assembly (Figure 7).
Figure 4A – HC-450 Warning Label

Figure 4B – HC-300 Warning Labels
• Presence and readability of the warning labels (see
Figures 4A and 4B).
• Any other condition which may prevent safe and
normal operation.
If any problems are found, do not use the hole cutting
tool until the problems have been repaired.
4 Inspect the arbor, hole saw and drills to be used
with the Hole Cutting Tool for wear, deformation,
breakage or other issues. Do not use dull or damaged
cutting tools. Dull or damaged cutting tools increase
the amount of force required, produce poor quality
cuts and increase the risk of injury.
5. With dry hands, plug the cord in. Test the GFCI in the
electrical cord to insure that it is operating correctly.
When the test button is pushed in, the reset button
should pop out. Reactivate by pushing the reset but-
ton. If the GFCI is not functioning properly, unplug the
cord and do not use the hole cutting tool until the
GFCI has been repaired.
6. With the Hole Cutting Tool on a stable surface check
the Hole Cutting Tool for proper operation. Keep
clear of the chuck. Move the ON/OFF switch to the
ON position. The motor should start and the chuck
turn counter clockwise viewed from the chuck end.
Inspect the tool for misalignment, binding, odd noises
or other unusual conditions. Move the ON/OFF switch
to the OFF position. If any issues are found, do not
use the tool until it has been repaired.
7. After the inspection is complete, with dry hands un-
plug the tool.

Machine And Work Area Set-Up
WARNING
Set up the Hole Cutting Tool and work area ac-
cording to these procedures to reduce the risk of in-
jury from electrical shock, entanglement, crushing
and other causes and prevent tool damage.
Properly secure the Hole Cutting Tool to the pipe.
Improperly secured Hole Cutting Tools can slip and
fall and cause striking and crushing injuries.
Do not use for hot tapping. When cutting into an ex-
isting system, the pipe must be drained and de-
pressurized prior to cutting. This reduces the risk of
electrical shock and other serious injuries.
When working overhead, all personnel should wear
hard hats and be clear of the area below. This re-
duces the risk of serious injury should equipment or
other objects fall.
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite. If
present, do not work in area until sources have
been identified and corrected. The hole cutter is
not explosion proof and can cause sparks.
• Clear, level, stable, dry location for all of the equip-
ment and operator.
• Properly grounded electrical outlet of the correct
voltage. A three prong or GFCI outlet may not be
properly grounded. If in doubt, have outlet inspected
by a licensed electrician.
• Clear path to electrical outlet that does not contain
any potential sources of damage for the power cord.
2. Inspect the work to be done. Determine the pipe type
and size, and clearance around the pipe. Determine
the size and location of the hole to be cut. Clearly
mark the cut location. If installing a fitting, follow the fit-
ting manufacturer’s instructions. Determine the correct
equipment for the job. See the Description and Speci-
fication sections for tool information.
Make sure that the pipe to be cut is well supported and
stable. The pipe must be able to handle the weight of
the Hole Cutting Tool and the forces applied during
cutting without moving.
If working on an existing system, make sure that the
system has been depressurized and drained. The
Hole Cutting Tools are not designed for hot tapping
purposes. Cutting into pressurized or systems with flu-
ids in them can cause spills, electrical shock and
other serious injury. Know the contents of the pipe and
any specific hazards associated with the contents.
3. Confirm that the equipment to be used has been pro-
perly inspected,
4. Select an appropriate hole saw for the work to be
performed. Make sure that the hole saw is properly as-
sembled per its instructions and is in good working
order. The use of a pilot drill is recommended. The
pilot drill should extend no more than 3/8" (10mm) past
the end of the hole saw, and should be securely
tightened.
5. With the Hole Cutting Tool on a stable surface, install
the hole saw into the chuck. Always make sure that
the ON/OFF switch is in the OFF position and the Hole
Cutting Tool is unplugged before installing or chang-
ing the hole saw or drill.
• Open the chuck wide enough for the shank of the
hole saw. If needed, the chuck key can be used to
open the chuck. Make sure that the shank and the
chuck jaws are clean.
• Fully insert the shank into the chuck. Make sure
that the hole saw is centered in the chuck and
firmly tighten the chuck by hand.
• Use the chuck key in all three chuck holes to se-
curely tighten the chuck onto the shank. Make
sure to remove the chuck key from the chuck be-
fore turning the tool ON.
Mounting The Hole Cutting Tool
On The Pipe
Hole Cutting Tools weigh up to approximately 42 pounds.
Use good lifting technique when placing on the pipe,
do not overreach, and keep good balance and footing at
all times. Depending on the circumstances, two people
may be necessary to mount the Hole Cutting Tool onto
the pipe.
Hole Cutting Tools can be used at any angle or orienta-
tion. If cutting a hole on the side or bottom of a pipe, it
may be easier to place the Hole Cutting Tool on the
top of the pipe to fasten the chain around the pipe and
then move the Hole Cutting Tool into final position.
HC-450
1. Make sure the chain is hanging freely and the swivel
handle is fully loosened.
2. Carefully lift the HC-450 Hole Cutting Tool and place
with the V-shaped guides squarely on the pipe near the
7
HC-450/HC-300 Hole Cutting Tools

location of the cut. Make sure the chain is not be-
tween the pipe and tool base.
3. Always keep at least one hand on the Hole Cutting
Tool to stabilize and guide it. Grasp the end of the
chain and pull it snugly around the pipe. Hook the
closest chain pin on the wear plate and firmly tighten
the swivel handle to hold the Hole Cutting Tool to the
pipe.
(See Figure 5)
Figure 5 – Hooking the HC-450 Chain
4. The base of the HC-450 Hole Cutting Tool includes a
level vial that can be used to align a series of holes.
When the Hole Cutting Tool is placed at the desired
angle, the vial can be rotated to the level position,
and subsequent holes can be made at the same
angle by leveling the Hole Cutting Tool with the vial.
(See Figure 6)
Figure 6 – HC-450 Hole Cutting Tool Level Vial
5. With one hand on the Hole Cutting Tool to stabilize and
guide it, slightly loosen the swivel handle to allow final
positioning of the tool. Align the pilot drill with the de-
sired cut location, and firmly tighten the swivel handle.
Do not remove your hands from the Hole Cutting Tool
until you have confirmed that it is securely attached to
the pipe. The Hole Cutting Tool must be securely and
squarely attached to the pipe to help reduce the risk of
hole saw jamming.
HC-300
The HC-300 can be mounted on the pipe either as a
complete unit (similar to the HC-450) or by separating the
base assembly from the tool, mounting the base to the
pipe, and then installing the motor assembly to the base
assembly.
1. With the HC-300 Hole Cutting Tool on a stable, secure
surface, pull the plunger on the back of the left post
(Figure 7) and lift the motor assembly off of the base
assembly.
Figure 7 – Separating the Base and Motor Assemblies
2. Make sure the chain is hanging freely and the swivel
handle is fully loosened on the base assembly.
3. Place the base assembly with the V-shaped guides
squarely on the pipe near the location of the cut.
Make sure the chain is not between the pipe and tool
base.
4. Always keep at least one hand on the base assembly
to stabilize and guide it. Grasp the end of the chain and
pull it snugly around the pipe. As you pull on the
chain, a spring is compressed at the attachment end of
the chain. Hook the closest chain pin on the chain hook
– the spring tension will help keep the chain engaged
with the chain hook. Firmly tighten the crank screw as-
sembly to hold the base assembly to the pipe. (See
Figure 8.)

7. With one hand on the Hole Cutting Tool to stabilize
and guide it, slightly loosen the crank screw assembly
to allow final positioning of the tool. Align the pilot
drill with the desired cut location, and firmly tighten the
crank screw assembly. Do not remove your hands
from the Hole Cutting Tool until you have confirmed
that it is securely attached to the pipe. The Hole
Cutting Tool must be securely and squarely attached
to the pipe to help reduce the risk of hole saw jam-
ming.
To mount the HC-300 on the pipe as a complete unit, fol-
low the steps indicated in the HC-450 section, using
the information in the HC-300 section on chain hooking
and alignment.
Powering the Hole Cutting Tool
1. Confirm that the ON/OFF switch is in the OFF position.
2. Makes sure that the power cord is routed out the
back of the tool away from the chuck and work area.
Run the cord along the clear path to the outlet, and
with dry hand plug in. Keep all connections dry and off
the ground. If the power cord is not long enough, use
an extension cord that:
• Is in good condition
• Has a three prong plug similar to that on the tool.
• Is rated for outdoor use and contains a W or W-A in
the cord designation (i.e. SOW), or complies with
H05VV-F, H05RN-F types or IEC type design
(60227 IEC 53, 60245 IEC 57).
• Has sufficient wire size (16 AWG (1.5mm2) for 50'
(15.2m) or less, 14 AWG (2.5mm2) for 50' – 100'
(15.2m – 30.5m) long). Undersized wires can over-
heat, melting the insulation or causing a fire or other
damage.

10
HC-450/HC-300 Hole Cutting Tools
When using an extension cord, the GFCI on the
Hole Cutting Tool does not protect the extension
cord. If the outlet is not GFCI protected, it is advisable
to use a plug in type GFCI between the outlet and the
extension cord to reduce the risk of shock if there is a
fault in the extension cord.
Operating Instructions
WARNING
Always wear appropriate eye protection. Cutting
tools can break or shatter. Cutting produces chips
that can be thrown or fall into eyes.
Do not use for hot tapping. When cutting into an
existing system, the pipe must be drained and
depressurized prior to cutting. This reduces the
risk of electrical shock and other serious injury.
Do not wear gloves or loose clothing when operat-
ing machine. Keep Sleeves and jackets buttoned.
Do not reach across machine. Clothing can be
caught by the machine resulting in entanglement.
Keep fingers and hands away from rotating chuck
and saw. This reduces the risk of entanglement
and cutting injuries.
Follow operating instructions to reduce the risk of
injury from electrical shock entanglement, crush-
ing and other causes and prevent Hole Cutter
damage.
1. Confirm that the Hole Cutting Tool and work area are
properly set up and that the work area is free of by-
standers and other distractions.
2. Assume a proper operating position that will allow:
• Control of the Hole Cutting Tool, including the ON/-
OFF switch and the feed handle. On the HC-300
you must be on the same side as the switch and the
feed handle. Do not turn the tool ON yet
• Good balance. Be sure that you do not have to over
reach.
3. Move the ON/OFF switch to the ON position. Observe
the rotation of the hole saw and pilot drill, making
sure it is running straight and true. If they wobble, or
any other issues are noted, move the switch to OFF
and unplug tool, fix any issues prior to using. Keep fin-
gers, hands and clothes away from the turning chuck
to help reduce the risk of entanglement.
4. Place both hands on the hand wheel and advance the
pilot drill into contact with the pipe. Apply firm pres-
sure, and start drilling the pilot hole. Do not force
the pilot drill/hole saw. This can overload the hole saw
and the tool motor and cause premature failure.
Figure 11 – Operating the Hole Cutting Tool
Once the hole saw is in contact with the pipe, con-
tinue to apply firm pressure. Depending on the size
and wall thickness of the pipe and the size of the hole
being cut, the hole saw may need to be retracted
slightly at times for chip removal.
If needed, the Hole Cutting Tool can be shut off and
a small amount of appropriate cutting lubricant applied
to the work piece. Do not apply lubricant while the tool
is running, this increases the risk of entanglement.
Take appropriate steps to prevent the lubricant from
dripping or being thrown during use.
As the hole saw moves through the pipe and as the
cut is completed, there will be an interrupted cut at
times. Decrease pressure as this occurs to help pre-
vent jamming of the hole saw.
5. Once the hole is complete, retract the hole saw from
the pipe and turn the ON/OFF switch OFF.
6. Reverse the mounting procedure to remove the Hole
Cutting Tool from the pipe. Make sure you have se-
cure grip on the Hole Cutting Tool prior to loosening
the chain or pulling the plunger on the HC-300.
7. If the pipe slug needs to be removed from the hole
saw, always make sure that the ON/OFF switch is in
the OFF position and the Hole Cutting Tool is un-
plugged before removing. Remove the slug with
care, the slug may be hot and edges can be sharp.

Lubrication
The Hole Cutting Tools gearboxes are designed as
sealed systems, and should not require any additional
grease unless significant leakage has occurred. In those
cases, the tools should be returned to a service center.
Do not lubricate the bearings that ride on the posts.
The bearings are not designed to be used with lubricants,
and lubricants will hold dirt and debris that could damage
the bearings.
As needed, the chain and screw assemblies can be lu-
bricated with a light lubricating oil. Wipe any excess oil
from exposed surfaces.
Changing Brushes
Check motor brushes every six months and replace
when worn to less than 1/2".
1. Remove four screws holding motor cover, remove
cover.
2. Using a pair of pliers, pull the motor brushes straight
out. Detach the connector. (See Figure 12)
Figure 12 – Brush Placement - Motor Cover Removed
3. Inspect the commutator for wear. If excessively worn,
have tool serviced.
4. Depress the brush into the holder and insert into the
motor housing. Inspect to make sure insulator sheets
are properly positioned between brush holder and
housing. Attach the connector and replace the motor
cover.
Gib Screw Adjustment
Gib screws are provided on the HC-450 to allow ad-
justment of the drag between the base and motor as-
semblies. Tighten or loosen the Gib screws to adjust as
