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.
Work Area Safety
• Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases, or dust. 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 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 body contact with grounded surfaces. There is an increased risk of electrical shock if
your body is grounded.
• Don’t expose electrical tools to rain or wet conditions. Water entering a tool will increase the
risk of electrical shock.
• 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.
• Keep all electric connections dry and off the ground. Do not touch plugs or tool with wet
hands. Reduces the risk of electrical shock.
Personal Safety
• 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 influence of drugs, alcohol, or medications. A moment
of inattention while operating power tools may result in serious personal injury.
• 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.
• 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
• Remove adjusting keys or wrenches before turning the tool ON. A wrench or a key left
attached to a rotating 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 better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard
hat, or hearing protection must be used for appropriate conditions.
Tool Use and Care
• Use clamps or other practical way to secure and support the workpiece to a stable platform.
Holding the workpiece 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 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.
• Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventive safety measures reduce the risk of starting
the tool accidentally.
• Store idle tools out of the reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
• 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 for your tool. Accessories that may be suitable
for one tool may become hazardous when used on another tool.
• Keep handles dry and clean; free from oil and grease. Allows for better control of the tool.
Machine Safety
• Always wear appropriate eye protection. Cutting tools can break or shatter. Cutting
produces chips that can be thrown or fall into eyes.
• Do not wear gloves or loose clothing when operating 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.
• Properly secure the Hole Cutting Tool to the pipe. Improperly secured Hole Cutting Tools
can 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 depressurized prior to cutting. This reduces the risk of electrical shock and other serious
injury.
• Before using, test the Ground Fault Circuit Interrupter (GFCI) provided with the power cord
to insure it is operating properly. GFCI reduces the risk of electrical shock.
• When working overhead, all personnel should wear hard hats and be clear of the area below

Pre-Operation Inspection
Before each use, inspect your Hole Cutting Tool 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, 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 Interrupter (GFCI) and plug for damage or
modification.
• Proper assembly and completeness.

5
• 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.
• 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 button. 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 unplug the tool.
Machine And Work Area Set-Up
Warning: objects falling and electrical shock
Set up the Hole Cutting Tool and work area according to these procedures to reduce
the risk of injury 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 existing system, the pipe must be drained and
depressurized 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 reduces 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.

6
• Clear, level, stable, dry location for all of the equipment 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 fitting manufacturer’s instructions. Determine the correct
equipment for the job. See the Description and Specification 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 fluids 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 properly inspected,
4. Select an appropriate hole saw for the work to be performed. Make sure that the hole saw
is properly assembled per its instructions and is in good working order.
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 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 securely
tighten the chuck onto the shank. Make sure to remove the chuck key from the chuck before
turning the tool ON.
Mounting The Hole Cutting Tool On The Pipe
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 orientation. 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.
1. Make sure the chain is hanging freely and the swivel handle is fully loosened.
2. Carefully lift the JK114 Hole Cutting Tool 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.
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

7
plate and firmly tighten the swivel handle to hold the Hole Cutting Tool to the pipe.
4. The base of the JK114 Hole Cutting Tool includes a level vial that can be used to align a
series of holes. (as photo above)
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 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.
Operating Instructions
Warning: eye protection, cutting injury and entanglement danger
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 operating 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, crushing 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 bystanders 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. 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 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, continue 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 prevent jamming of the hole saw.
5. Once the hole is complete, retract the hole saw from the pipe and 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.
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 unplugged before
removing. Remove the slug with care, the slug may be hot and edges can be sharp.
