3. Do not overreach when operating the tool. Proper footing and
balance enables better control in unexpected situations.
4. Support the workpiece or clamp it to a stable platform. Holding the
workpiece by hand or against your body may lead to personal injury.
5. Securely hold this tool using both hands. Using a tool with only one
hand can result in loss of control.
6. Use clamps or other practical ways to support or secure the
workpiece to a stable platform.
SPECIFIC SAFETY PRECAUTIONS
1. Only use accessories that are specifically designed for use with the
tool. Make sure accessories are capable of handling the tool's
maximum speed of 24,000 RPM. Ensure the accessory is
tightly installed.
2. Keep hands and fingers away from cutting area. Any body part
coming in contact with moving parts could cause injury.
3. To maintain complete control, firmly hold your tool with both hands.
Do not place hands over air vents. Proper cooling of the motor is
necessary to ensure normal life of the tool.
4. Never point the cutter towards yourself. If it should slip, part of your
body could come in contact with moving parts.
5. Never force the tool. Excessive pressure could bend or break the
mandrel, resulting in damage to the tool, your workpiece or serious
personal injury. If your cut-off tool runs smoothly under no load, but
does not run smoothly under load, then excessive pressure is
being used.
6. This tool will not stop moving immediately. Do not lay the tool down
or leave it unattended until it has come to a complete stop. A part that
is moving could make the tool jump or grab a surface and pull the
tool out of your control.

7. Hold the tool by the insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring or its own
cord. Contact with a"live" wire will make exposed metal parts of the
tool "live" and shock the operator.
8. Always make sure the work surface is free from nails and other
foreign objects. Cutting into a nail can cause the tool to jump.
9. After changing the cutting wheel and accessories or making
adjustments, make sure the collet nut and any other adjustment
devices are securely tightened. Loose adjustment devices will be
violently thrown.
10. Remove any adjusting keys or wrenches before turning the power
tool on.
11. Always use the correct collet size. If the collet size is larger than the
accessory shank size it will not grip the shank properly, leading to
possible injury to the operator , damage to the tool or the workpiece.
12. Always check cut-off wheels for damage before each use. Damaged
accessories can break during use and cause serious injury.
13. Never use dull or damaged cut-off wheels. Sharp cut-off wheels must
be handled with care. Damaged cut-off wheels can snap during use.
Dull cut-off wheels require more force to push the tool, possibly
causing the cut-off wheel to break.
14. Never touch the cutting wheel or workpiece during or immediately
after use. After use, the cutting wheel and workpiece will be too hot
to be touched by bare hands.
15. If devices are used for the connection of dust extraction and
collection facilities, ensure these are connected and properly used.
Use of a dust collection system reduces dust-related hazards.
16. Do not use accessories that require liquid coolants. Using water or
other liquid coolants may result in shock or electrocution.

ELECTRICAL SAFETY
1. Disconnect power supply. Disconnect the tool from the power supply
when not in use, before cleaning, servicing or changing any parts.
2. Protect yourself against electric shocks when working on electrical
equipment. Avoid body contact with grounded surfaces such as
pipes, radiators, cooking stoves and refrigerators. There is an
increased chance of electrical shock if your body is grounded.
3. 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 does not fit, contact a qualified electrician to install a polarized
outlet. Do not change the plug in any way. Double insulation
eliminates the need for a three wire grounded power cord and
grounded power supply system.
4. Grounded tools must be plugged into an outlet that is 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 electronically malfunction or break down, grounding provides
a low resistance path to carry electricity away from the user.
5. Do not abuse the cord. Never use the cord to carry tools or pull the
plug from an outlet. Keep the cord away from heat, oil, sharp edges
or moving parts. Do not operate this tool if the power cord is frayed
or damaged. Replace damaged cords immediately. Damaged cords
increase the risk of electric shock. Do not modify the plug in any way.
Visit www.princessauto.com for more information 7

8567356 3 in. 3.5A Electric Cut·Off Tool V4.0
6. 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. Use in conjunction with a Ground
Fault Circuit Interrupter (GFCI). If operating a power tool in a damp
location is unavoidable, the use of a GFCI reduces the risk of electric
shock. It is recommended that the GFCI should have a rated residual
current of 30 mA or less.
7. Avoid using an unnecessarily long extension cord. Choose a cord that
is appropriate for the situation, as a cord that is too long and running
across the floor can be more dangerous than helpful. Using a cord
that is too long or too thin could damage the tool. Unroll the cord
completely to prevent it from overheating.
8. Place the electrical cord in a position that prevents it from coming
into contact with the tool and from getting caught by the work piece.
The cord should always stay behind the tool.
9. Keep all connections dry and off the ground to reduce the risk of
electric shock. Do not touch the plug with wet hands.
WARNING! People with pacemakers should consult their physician(s)
before using this product. Operations of electrical equipment in close
proximity to a heart pacemaker could cause interference or failure of
the pacemaker.
LOW VOLTAGE
Low voltage may cause overheating due to higher power current being
drawn to the tool that will shorten the motor life.
An extension cord may cause a drop in power to the tool if it is too long
or the amperage rating is not correct. This may result in the following:
1. The tool will not activate when switched on.
2. The tool may switch on, but fails to maintain power when applied to
a workpiece.
3. The tool may overheat, possibly starting a fire.
8
For technical questions call1·800-665-8685

V4.0 3 in. 3.5A Electric Cut·Off Tool 8567356
Test the tool by plugging it directly to the power supply. If it powers on,
change the extension cord with the correct rating and as short as needed.
The workpiece may also need to be relocated closer to the power supply.
KICKBACK PRECAUTIONS
Kickback is a sudden reaction to a pinched, bound or misaligned disc,
causing an uncontrolled tool to lift up and out of the workpiece toward
the operator; - when the disc is pinched or bound tightly by the
workpiece closing down, the disc stalls and the motor reaction drives the
tool rapidly back toward the operator. Kickback may result in loss of
control of the tool leading to serious personal injury and I or damage to
the workpiece and I or tool.
Kickback can be avoided by taking proper precautions:
1. Maintain a firm grip on the tool and position your body and arms to
allow you to resist kickback forces. Kickback will propel the tool in
the direction opposite to the wheel's movement at the time
of snagging.
2. Never place your hand near the disc. If kickback occurs, the disc may
pass over your hand and seriously injury you. Use clamps or a vice to
hold down the workpiece.
3. Use special care when working on corners, sharp edges etc. Corners,
sharp edges or bouncing have a tendency to snag the disc and cause
loss of control or kickback.
4. When the disc is binding, or when interrupting a cut for any reason,
release the trigger and hold the tool motionless in the material until
the tool comes to a complete stop. Never attempt to remove the tool
from the workpiece or pull the tool backward while the disc is in
motion or kickback may occur. Investigate and take corrective actions
to eliminate the cause of disc binding.

9

8567356 3 in. 3.5A Electric Cut·Off Tool V4.0
5. Never restart the cutting operation in the workpiece. Allow the wheel
to reach full speed and carefully reenter the cut. If saw blade is
binding, it may walk up or kickback from the workpiece as the cut-off
saw is restarted.
6. Support large panels to minimize the risk of disc pinching and
kickback. Large panels tend to sag under their own weight. Supports
must be placed under the panel on both sides, near the line of cut
and near the edge of the panel.
7. To minimize the risk of disc pinching and kickback, when cutting
operation requires the resting of the tool on the workpiece, the tool
should be rested on the larger portion and the smaller piece cut off.
8. Use extra caution when making a "plunge cut" into existing walls or
other blind areas. The protruding disc may cut objects that can
cause kickback.
9. Only use discs designed for tool. Do not use dull or damaged discs.
Unsharpened or improperly set discs produce narrow cut causing
excessive friction, disc binding and kickback. Keep discs sharp and
clean. Gum and wood pitch hardened on blades slows the tool and
increases potential for kickback.
10. Never force the tool. Forcing the tool can cause uneven cuts, loss of
accuracy, and possible kickback. Push the tool forward at a speed so
that the disc cuts without slowing.
VIBRATION PRECAUTIONS
This tool vibrates during use. Repeated or long-term exposure to
vibration may cause temporary or permanent physical injury, particularly
to the hands, arms and shoulders.
10 For technical questions call1·800-665-8685

V4.0 3 in. 3.5A Electric Cut·Off Tool 8567356
1. Anyone using vibrating tools regularly or for an extended period
should first be examined by a doctor and then have regular medical
check-ups to ensure medical problems are not being caused by or
worsened from tool use. Pregnant women or people who have
impaired blood circulation to the hands, past hand injuries, nervous
system disorders, diabetes, or Raynaud's Disease should not use this
tool. If you feel any medical symptoms related to vibrations (such as
tingling, numbness, and white or blue fingers), seek medical attention
as soon as possible.
2. Do not smoke during use. Nicotine reduces the blood flow to the
hands and fingers, increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the vibration effects on the user.
4. Use tools with the lowest amount of vibration when there is a choice
between different processes.
5. Do not use for extended periods. Take frequent breaks when using
this tool.
6. Let the tool do the work. Grip the tool as lightly as possible (while
still keeping safe control of it).
WARNING! If abnormal vibrations occur, stop using this
tool immediately.

MAINTENANCE
It has been found that electric tools are subjected to accelerated wear and
possible premature failure when they are used for cutting and grinding
metals. The grindings from these materials are highly abrasive to electric
tool parts such as bearings, brushes, commutators, etc. Consequently, it
is not recommended that this tool be used for extended work on any
metals. During any use on these materials it is extremely important that
the tool is cleaned frequently by blowing it out with an air jet.
CAUTION! Disconnect the power cord from the power supply before
any maintenance or cleaning. Do not use water or corrosive fluids to
clean electrical parts of the tool.
1. Maintain the tool with care. A tool in good condition is efficient,
easier to control and will prevent unnecessary problems.
2. Keep the tool handles clean, dry and free from oil/grease at all times.
3. Follow instructions for changing accessories.
4. Inspect the tool fittings periodically. Have damaged or worn
components repaired or replaced by an authorized technician.
5. Inspect the tool fittings, alignment, power supply cord and
components periodically. Have damaged or worn components
repaired or replaced by an authorized technician.
6. Sharp tools are safer than dull tools. Applying excessive force while
using a dull tool can lead to slips and cause damage to your work
piece or personal injury.
