General Safety Rules*
WARNING
Read and understand all instructions. Failure to fol-
low all instructions listed below may result in elec-
tric 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
liquids, 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 qual-
ified electrician if you are in doubt as to whether
the outlet 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 bodycontactwithgroundedsurfacessuch
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car-
ry the tool or pull the plug from an outlet. Keep
cord away from heat, oil, sharp edges or mov-
ing parts. Replace damaged cords immediately.
Damaged cords increase the risk of electric shock.
•Whenoperatinga powertooloutside,useanout-
door extension cord marked“W-A” or “W”. These
cords are rated for outdoor use and reduce the risk
of electric shock.
* The text used in the General Safety Rule section of this manual is verbatim, as required, from the applicable UL/CSA 745 1st edition standard. This section

premature failure. Careful evaluation of materials and
methods for the specific service conditions, including
chemical and temperature, should be completed be-
fore any installation is attempted.
Pre-Operation Inspection
WARNING
Before each use, inspect your Hole CuttingTool and
correct any problems to reduce the risk of serious
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, includ-
ing 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 modifica-
tion.
•Proper assembly and completeness.
•Broken, worn, missing, mis-aligned or binding
parts. Make sure that the motor assembly moves
smoothly and freely up and down the posts of
the base assembly. Confirm that the chain and
swivel handle move freely. On the HC-300, con-
firm that the plunger pin functions properly and
retains the motor assembly to the base assembly
(Figure 7).
•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 cut-
ting 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, break-
age or other issues. Do not use dull or damaged cut-
ting 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
button. If the GFCI is not functioning properly, un-
plug the cord and do not use the hole cutting tool
until the GFCI has been repaired.
6. With the Hole CuttingTool 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 nois-
es 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
unplug the tool.

HC-450/HC-300 Hole Cutting Tools
Machine AndWork Area Set-Up
WARNING
Set up the Hole Cutting Tool and work area ac-
cording to these procedures to reduce the risk of
injury from electrical shock, entanglement, crush-
ing 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
existing 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 ig-
nite. If present, do not work in area until sources
have been identified and corrected.The hole cut-
ter is not explosion proof and can cause sparks.
•Clear,level,stable, dry locationfor allofthe 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 in-
spected 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. De-
termine the size and location of the hole to be cut.
Clearly mark the cut location. If installing a fitting,
follow the fitting manufacturer’s instructions. De-
termine the correct equipment for the job. See the
Description and Specification sections for tool infor-
mation.
Make sure that the pipe to be cut is well support-
ed 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 fluids in them can cause spills, elec-
trical shock and other serious injury. Know the
contents of the pipe and any specific hazards as-
sociated with the contents.
3. Confirm that the equipment to be used has been
properly inspected.
4. Select an appropriate hole saw for the work to be
performed. Make sure that the hole saw is prop-
erly assembled per its instructions and is in good
working order. The use of a pilot drill is recom-
mended. The pilot drill should extend no more
than 3/8”/ 10 mm past the end of the hole saw, and
should be securely tightened.
5. With the Hole Cutting Tool on a stable surface, in-
stall 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 install-
ing or changing 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.
MountingThe Hole CuttingTool On
The Pipe
Hole Cutting Tools weigh up to approximately
42 pounds / 19 kg. 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 neces-
sary 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 swiv-
el handle is fully loosened.
2. Carefully lift the HC-450 Hole CuttingTool and place
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.

HC-450/HC-300 Hole Cutting Tools

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 tight-
en the swivel handle to hold the Hole Cutting Tool
to the pipe. (See Figure 5.)
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.)
5. With one hand on the Hole CuttingTool to stabilize
and guide it, slightly loosen the swivel handle to al-
low final positioning of the tool. Align the pilot drill
with the desired 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 assem-
bly off of the base assembly.
2. Make sure the chain is hanging freely and the swiv-
el 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 assem-
bly 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 assembly to
hold the base assembly to the pipe. (See Figure 8.)

openings in the motor assembly with the posts of
the base assembly. Press the motor assembly on
until the plunger engages the post to retain the
motor assembly to the base. Confirm that the mo-
tor assembly is securely attached to the base. (See
Figure 9.)
6. The base of the HC-300 includes several machined
flats for use with levels for hole alignment. (See Fig-
ure 10.)
7. With one hand on the Hole CuttingTool to stabilize
and guide it, slightly loosen the crank screw assem-
bly 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 jamming.
To mount the HC-300 on the pipe as a complete unit,
follow the steps indicated in the HC-450 section, using
the information in the HC-300 section on chain hook-
ing and alignment.
Powering the Hole CuttingTool
1. Confirm that the ON/OFF switch is in the OFF posi-
tion.
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 out-
let, 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 com-
plies with H05VV-F, H07VV-F, H05RN-F, H07RN-F
types or IEC type design (60227 IEC 53, 60245 IEC
57).
•Has sufficient wire size (16 AWG / 1,5 mm2for 50’/
15,2 m or less, 14 AWG / 2,5 mm2for 50’ – 100’ /
15,2 m – 30,5 m long). Undersized wires can over-
heat, melting the insulation or causing a fire or
other damage.

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 ad-
visable 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 de-
pressurized prior to cutting.This reduces the risk of
electrical shock and other serious injury.
Do not wear gloves or loose clothing when operat-
ingmachine.KeepSleevesandjacketsbuttoned.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 dam-
age.
1. Confirm that the Hole Cutting Tool and work area
are properly set up and that the work area is free of
bystanders and other distractions.
2. Assume a proper operating position that will al-
low:
•ControloftheHole CuttingTool,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. Ob-
serve 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 fingers, 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
pressure, 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.
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 CuttingTool 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 dur-
ing 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
prevent 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 secure 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.

sition and the tool is unplugged before performing
any maintenance or making any adjustments.
Maintain tool according to these procedures to re-
duce the risk of injury from electrical shock, entan-
glement and other causes.
Cleaning
After each use, wipe any chips or oil off with a soft, clean,
damp cloth, especially areas of relative motion such as
the posts. Clean any dust and debris from the motor
vents.
Lubrication
The HoleCuttingTools gearboxes aredesigned assealed
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 dam-
age 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”/ 1,3 cm.
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.)
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 insula-
tor sheets are properly positioned between brush
holder and housing. Attach the connector and re-
place 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
