WORK AREA
1. Keep your work area clean and well lit. Cluttered and dark areas
invite accidents.
2. Operate in a safe work environment. Do not use machines or air tools in
damp or wet locations. Do not expose to rain. Do not use power tools in
the presence of flammable gases or liquids.
3. Keep children, bystanders and visitors away from the work area. Do not
let them handle tools or extension cords. No one should be in the work
area if they are not wearing suitable protective equipment.
4. Store unused equipment. When not in use, tools must be stored in a
dry location to prevent rust. Always lock up tools and keep them out of
reach of children.
PERSONAL SAFETY
1. Dress properly, wear protective equipment. Use breathing, ear, eye,
face, foot, hand and head protection. Always wear ANSI approved
impact safety goggles, which must provide both frontal and side
protection. Protect your hands with suitable gloves. Wear a full
face shield if your work creates metal filings or wood chips. Protect
your head from falling objects by wearing a hard hat. Wear an ANSI
approved dust mask or respirator when working around metal,
wood and chemical dusts and mists. Wear ANSI approved earplugs.
Protective, electrically non-conductive clothes and non-skid footwear
are recommended when working. Wear steel toed boots to prevent
injury from falling objects.
2. Do not over reach; keep proper footing and balance at all times.
Proper footing and balance enables better control of the tool in
unexpected situations.
3. Keep any articles of clothing, jewelry, hair etc. away from moving parts.
These can be caught in moving parts, resulting in damage to the tool
and/or serious injury.
4. Stay alert, watch what you are doing and use your common sense. Do
not operate any machine or tool when you are tired, under the influence
of drugs, alcohol or medications.

5. Use clamps or other practical ways to secure and support the work
piece to a stable platform. Holding the work piece by hand or against
your body is unstable and may lead to loss of control.
6. Do not allow the spray to strike you and do not spray toward people or
animals. Do not spray the tool itself or any electrical source.
ELECTRICAL SAFETY
1. Disconnect power supply. Disconnect from power supply when not in
use, before cleaning, servicing or changing any parts or accessories.
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 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 the tools or pull
the plug from an outlet. Keep 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.

6For technical questions call: 1-800-665-8685
8383853V 2.0
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.
SPECIFIC SAFETY PRECAUTIONS
WARNING! Know your multi-function power tool. Do not plug the tool
into the power source until you have read and understand this Instruction
Manual. Learn the tool’s applications and limitations, as well as the specific
potential hazards related to this tool. Following this rule will reduce the risk
of electric shock, fire, or serious injury.
• Always keep hands out of the path of the saw blade. Avoid awkward
hand positions where a sudden slip could cause your hand to move into
the path of the saw blade.
• Secure workpiece. Use clamps or a vice to hold the workpiece. It is
safer than using your hand and it frees both hands to operate the tool.
• Make sure there are no nails or foreign objects in the part of the
workpiece to be cut or sanded.
• To avoid injury from accidental starting, always remove the plug from
the power source before installing or removing an accessory.
• Never use dull blades in the tool. They will cut slower, leave rough cuts
and break easily due to added pressure and excessive heat. They will
also overload the motor and cause premature failure of the tool.

TOOL USE AND CARE
1. Use the right tool for the job. Do not attempt to force a small tool
or attachment to do the work of a larger industrial tool. The tool will
perform better and more safely at the task for which it was intended. Do
not modify this tool or use for a purpose for which it was not designed.
2. Securely hold this tool using both hands. Using tools with only one
hand can result in loss of control.
3. Maintain tools with care. Keep tools clean, sharp and in good condition
for a better and safer performance. Follow instructions for lubricating
and changing accessories. Inspect tool fittings, alignment and hoses
periodically and, if damaged, have them repaired by an authorized
technician or replaced. The handles must be kept clean, dry and free
from oil and grease at all times. A properly maintained tool reduces the
risk of binding and is easier to control. Sharp tools are safer than tools
which have become dull because you do not have to apply excessive
amounts of force to make your cuts. Applying excessive force can lead
to slips and damage to your work or personal injury.
4. Remove adjusting keys and wrenches. Check that keys and adjusting
wrenches are removed from the tool or machine before connecting it. A
wrench or key that is left attached to a rotating part of the tool increases
the risk of personal injury.
5. Avoid unintentional starts. Be sure that the switch is in neutral or OFF
position when not in use and before connecting it to any power source.
Do not carry the tool with fingers near or on the switch.
6. Only use the lubricants supplied with the tool or specified by the
manufacturer. Other lubricants may not be suitable and may damage
the tool or even make the tool explode.
7. When not in use for an extended period, apply a thin coat of lubricant to
the steel parts to avoid rust.
8. Maintain the label and name plate on the tool. These carry important
information. If unreadable or missing, contact Princess Auto
