WARNING! Always check to ensure the power supply corresponds to
the voltage on the rating plate.
• Do not abuse the cord. Never carry a portable tool by its power cord,
or yank tool or extension cords from the receptacle. Keep powerand
extension cords away from heat, oil, sharp edges or moving parts. Replace
damaged cords immediately. Damaged cords may cause a fire and increase
the risk of electric shock.
• 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.
• Double insulated tools are equipped with a polarized plug
(one blade is wider than the other). This plug will fit in a polarized outlet only
one way. If the plug does not fit fully in the outlet, reverse the plug. If it still
doesn't fit, contact a qualified electrician to install a polarized outlet.
Do not change the plug in any way.

SAVE THESE INSTRUCTIONS
WORK AREA
• Keep work area clean, free of clutter and well lit. Cluttered and dark work
areas can cause accidents.
• Do not use your tool where there is a risk of causing a fire or an explosion;
e.g. in the presence of flammable liquids, gasses, or dust. Power tools create
sparks, which may ignite the dust or fumes.
• Keep children and bystanders away while operating a Hot Knife.
Distractions can cause you to lose control, so visitors should remain at a
safe distance from the work area.
• Be aware of all power lines, electrical circuits, water pipes and other
mechanical hazards in your work area, particularly those hazards below the
work surface hidden from the operator's view that may be unintentionally
contacted and may cause personal harm or property damage.
• Be alert of your surroundings. Using power tools in confined work areas
may put you dangerously close to cutting tools and rotating parts.
12

• Avoid body contact with grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increase risk of electric shock if your body
is grounded.
• 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 electric shock.
• Extension Cord Use:
A. Use only 'Listed' extension cords. If used outdoors, they must be
marked “For Outdoor Use.” Those cords having 3-prong grounding
type plugs and mating receptacles are to be used with grounded tools.
B. Replace damaged or worn cords immediately.
C. Check the name plate rating of your tool. Use of improper size or
gauge of extension cord may cause unsafe or inefficient operation of
your tool. Be sure your extension cord is rated to allow sufficient current
flow to the motor. For the proper wire gauge for your tool, see chart.
CHART FOR MINIMUM WIRE SIZE OF EXTENSION CORD:
If in doubt, use larger cord. Be sure to check voltage requirements of the tool
to your incoming power source.
• Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
• Do not let your fingers touch the terminals of plug when installing to
or removing from the outlet.
• Ground fault circuit interrupters. If work area is not equipped with a
permanently installed Ground Fault Circuit Interrupter outlet (GFCI),
use a plug-in GFCI between power tool or extension cord and power
receptacle.
• Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or
under the influence of drugs, alcohol or medication. A moment of inattention
while operating power tools may result in serious personal injury.
• Dress properly. Do not wear loose clothing, dangling objects, or jewelry.
Keep your hair, clothing and gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in moving parts. Air vents
often cover moving parts and should be avoided.
• Use safety apparel and equipment. Use safety goggles or safety glasses
with side shields which comply with current national standards, or when
needed, a face shield. Use as dust mask in dusty work conditions. This
applies to all persons in the work area. Also use non-skid safety shoes,
hardhat, gloves, dust collection systems, and hearing protection when
appropriate.
• Avoid accidental starting. Do not carry the power tool with your finger on
the switch. Ensure the switch is in the off position before plugging tool into
power outlet. In the event of a power failure, while a tool is being used, turn
the switch off to prevent surprise starting when power is restored.
• Do not overreach. Keep proper footing and balance at all times.
• Remove adjusting keys or wrenches before connecting to the power
supply or turning on the tool. A wrench or key that is left attached to a
rotating part of the tool may result in personal injury.
• Do not force the tool. Tools do a better and safer job when used in the
manner for which they are designed. Plan your work, and use the
correct tool for the job.
• Never use a tool with a malfunctioning switch. Any power tool that cannot
be controlled with the switch is dangerous and must be repaired by an
authorized service representative before using.
• Disconnect power from tool and place the switch in the locked or off
position before servicing, adjusting, installing accessories or attachments,
or storing. Such preventive safety measures reduce the risk of starting the
power tool accidentally.

• Secure work with clamps or a vise instead of your hand to hold work
when practical. This safety precaution allows for proper tool operation
using both hands.
• Store idle tools. When tools are not is use, store them in a dry, secure
place out of the reach of children. Inspect tools for good working condition
prior to storage and before re-use.
• Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may create a risk of
injury when used on another tool.
• Keep guards in place and in working order.
• Never leave tool running unattended.
When unpacking, check to make sure that the item is intact and undamaged.
If any parts are missing or broken, please call the distributor at the number

pacemakers should:
• Avoid operating alone.
• Do not use with Power Switch (19) locked on.
• Properly maintain and inspect to avoid electrical shock.
• Any Power Cord (21) must be properly grounded. Ground Fault Circuit
Interrupter (GFCI) should also be implemented – it prevents sustained
electrical shock.
