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.
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 label and name plate on the tool. These carry important information. If unreadable or missing,
contact Princess Auto for a replacement.
ELECTRICAL
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.
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 into the work piece. The cord should always stay behind the tool.
MAINTENANCE
• The brushes should be checked periodically and worn-out brushes should be replaced. After replacing, inspect
whether the new brushes can move freely in the brush holder. Run the motor for 15 minutes without load to
shape the brushes, so that they are properly aligned with the commutator.
• Keep the vent passage clear from dirt. Clean off the accumulated dust and oil dirt periodically.
• During normal operation, if anything happens, the power supply should be cut off at once and the tool should
be checked and repaired.
• Clean the tool after each use.
CAUTION! Only qualified service personnel should repair the tool.
REPLACING CARBON BRUSHES
• Using the parts list included, locate the carbon brushes. Remove the brush holder caps with a screwdriver and
inspect the carbon brushes. Replace them when they are worn up to about one third.
• Take the old brush out and install new brushes. Remove all of the brushes at once. Make sure the brush slides
freely within the brush housing.
• Run the motor for 15 minutes without load to shape the brushes, so that they are properly aligned with
the commutator.
UNPACKING
1. Carefully remove the parts and accessories from the box.
2. Make sure that all items listed in the parts lists are included.
3. Inspect the parts carefully to make sure the tool was not damaged while shipping.
4. Do not discard the packaging material until you have carefully inspected and satisfactorily operated the tool.
WARNING! If any part is missing, do not operate the tool until the missing parts are replaced. Failure to do so
could result in serious personal injury.

MAINTENANCE
BLADE REPLACEMENT
1. Disconnect the unit from the power source.
2. Move the movable blade guide and guard assembly forward to the end (Fig. 27).
3. Loosen the nuts A (Fig. 28), B (Fig.29) on the outer bearings of both movable and fixed guide assemblies, then
turn the bolts to allow the bearings to move away from the blade.
4. Remove the back blade cover by removing the screws with the small key put on the rear of the base.
5. Release the blade tension by turning the blade tension knob C (Fig.30) counter-clockwise.
6. Extract the blade from the guides and then remove it from around the wheels. (Wear gloves when handling
blades to prevent injury.)
7. Inspect the new blade for flaws (cracks, broken teeth, bending) before re-installing. The blade should be sharp
and have a correct set. Do not use a faulty saw blade.
8. Install the new blade through the guides and around the wheels, making sure the teeth are pointing in the
correct cutting direction.
9. Tighten the blade by turning the tension knob clockwise. The blade should be tensioned and tracked correctly
before proceeding. See “Blade Tension” and Blade Tracking above.
10. Turn the bolts on outer bearings to make the bearings contact lightly with the blade. Do not pinch the blade.
Next tighten the nuts carefully while keeping the bolts still.
11. Install the back blade cover and re-connect the unit to the power source.
12. A new blade must be “run in.” A carefully run-in blade lasts longer and gives better performance.
Let the blade run idle for about two minutes, then perform two or three cuts, preferably on a solid work-piece of
40 to 50 mm diameter. Use very light pressure on the blade, gradually increasing pressure with each cut. Refer
“Operation” for cutting procedures. (figs 27 to 30)
