PERSONAL SAFETY
1. Use eye, face, head, breathing and ear 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.
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. Dress properly, wear protective equipment. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Tie back long hair. Protective, electrically non-conductive clothes and non-skid footwear are
recommended when working.
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.
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 expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
6. 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.
7. 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.
8. 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.
9. 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.

SPECIFIC SAFETY PRECAUTIONS FOR GRINDERS
1. Do not start the tool if the grinding wheel is in contact with the work piece.
2. Always ensure the safety guards are attached correctly and do not operate the bench grinder without
the guards attached. Adjust the distance between the wheel and the tool rest to maintain a 1/16” or less
separation as the diameter of the wheel decreases with use.
3. Only use grinding or cutting wheels with the correct bore size for the spindle of the grinder.
4. Before beginning work on your project check if the grinding disc is in safe working condition. Before using
the tool on an actual work piece, make a test run of the tool at the highest no-load speed for at least
30 seconds in a safe position. Stop immediately if there is any vibration or wobbling that could indicate poor
installation or a poorly balanced wheel. You can find out if a disc is defective or cracked by letting it run at
no load in a safe environment with the guard between you and the disk. After a minute, if the disk has not
broken apart, it is considered in good working condition.
5. During long work periods do not allow the motor to overload and/or overheat, take frequent breaks.
6. A large amount of sparks will be created when working with the bench grinder. Hold the tool so that sparks
fly away from you and other persons or flammable materials.
7. When the machine is in operation, keep hands away from the grinding area. Plan the way you hold the
workpiece. Avoid awkward operations and hand positions where a sudden slip could cause fingers or hand
to move into grinding surface.
8. Use an appropriate dust respirator when working for an extended period of time. This will help prevent
breathing in the fine dust created while grinding.
CAUTION: Some surfaces contain materials that can be toxic. When working on materials that may
contain lead, asbestos, copper chromium arsenate or other toxic materials, extra care should
be taken to avoid inhalation and minimize skin contact.
9. The disc will not stop immediately when the machine is turned off. Exercise caution.
10. Do not touch the grinding surface immediately after use. The surface will be hot and you could
injure yourself.
11. Never stand on the tool. Serious injury could occur if the tool is tipped or if the wheel is
unintentionally contacted.
12. When replacing a wheel, make sure it is suited for the highest possible speed achievable by the grinder.
Wheels that are not rated for the tool’s no load speed may fly apart when used. After installing any wheel, let
it run freely for a minute before proceeding with the task to perform. Cracked, damaged or unsuitable wheels
will have flown apart by this time.
13. Do not grind on the sides of grinding wheels unless they are specifically designed for that purpose.
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. Maintain tools with care. Keep tools clean, and in good condition for a better and safer performance. Follow
instructions for changing accessories. Applying excessive force can lead to slips and damage to your work
or personal injury.

3. 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.
4. Avoid unintentional starts. Be sure that the switch is in the OFF position when not in use and before
connecting it to any power source.
5. When not in use for an extended period, apply a thin coat of lubricant to the steel parts to avoid rust.
6. Maintain label and name plate on the tool. These carry important information. If unreadable or missing,
contact Princess Auto for a replacement.

WARNING: The operation of any grinder can result in foreign objects being thrown into your eyes, which can
result in severe eye damage. Before beginning power tool operation, always wear safety goggles
or safety glasses with side shields and a full face shield when needed. We recommend Wide Vision
Safety Mask for use over eyeglasses or standard safety glasses with side shields.
BELT TRACKING
“Tracking” the sanding belt means to center the belt on its rollers, so that it runs balanced and does not make
contact with the sides of the belt cover.
To track the sanding belt:
1. DISCONNECT THE MACHINE FROM THE POWER SUPPLY!
2. Rotate the grinding wheel.
3. As you rotate the grinding wheel, watch how the sanding belt rides on
the upper roller. If the belt is tracking properly, the sanding belt should
be centered between the sides of the belt cover as shown in Fig. 1.
4. While spinning the wheel, turn the tracking control knob
counterclockwise to make the belt move to the left, or turn the tracking
control knob clockwise to make the belt move to the right.
5. After the belt is centered, spin the grinding wheel approximately ten
times to ensure that the belt continues to track properly.
ANGLE ADJUSTMENT
Loosen the two inner hex head screws to move the sanding arm to the desired
position. Then tighten the two inner hex head screws to set the angle.
BELT CHANGING
First loosen the safety guard fixing knob and then pull the belt changing
system to loosen the belt and replace it with a new one.
WHEEL REPLACEMENT
If you must replace a grinding wheel, be sure to obtain one with a safe rated
speed at least as high as the “no load speed” RPM marked on the data plate
of the grinder and which is marked to comply with ANSI B7.1.
To replace the grinding wheel, remove the wheel cover by loosening the
screws, Loosen the wheel nut in a clockwise direction for the left side and
a counterclockwise direction for the right side. Remove the outer flange
and grinding wheel. To install a new grinding wheel, reverse the above
procedure. Be sure the grinding wheel and outer flange are properly seated
on the spindle shaft.
