3. Never use a tool with a cracked or worn grinding wheel.
Change the grinding wheel before using. Use only flanges
supplied with the grinder.
4. Before using the tool on a workpiece, test the tool by running
it at the highest no-load speed for at least 60 seconds in a
safe position. Stop immediately if there is any abnormal
vibration or wobbling that could indicate poor installation of
the grinding wheel. Check the tool to determine the cause.
5. Do not start the tool when the grinding wheel is touching
the workpiece.
6. Never force the tool. Excessive pressure could break the
tool, resulting in damage to your workpiece or serious
personal injury. If your tool runs smoothly under no load,
but does not run smoothly under load, then excessive
pressure is being used.
7. Do not allow the tool’s motor to overload and/or overheat
by taking work breaks.

8. This tool will not stop moving immediately. Do not leave
the tool unattended until it has come to a complete stop.
9. Never touch the grinding wheel or workpiece during or
immediately after use. The grinding wheel or workpiece will
be too hot to be touched by bare hands.
10. Clean dust and debris from beneath the grinding
wheels frequently.
11. Do not stand directly in front of the machine when turning it
ON. Always stand off to the side of the machine and do not
allow any part of your body to be in line with the wheel’s path.
12. Do not grind magnesium or aluminum, as a fire may result.
13. Make sure the bench grinder is on a firm, level surface and
properly secured to avoid injury from unexpected movement.
Firmly clamp or bolt the bench grinder to a support surface
to prevent slipping or sliding during the operation.
14. Do not use a grinding wheel that vibrates when used. If
dressing the wheel does not solve the vibration, replace it.
Also inspect the machine for other causes of vibration such
as worn bearings or a bent shaft. Repair or replace broken
components immediately before reusing the machine.
15. Adjust the distance between a worn wheel and the tool rest
to maintain a 1/8 in. or less gap.
GRINDING TOOL PRECAUTIONS
1. Only use a grinding wheel of the recommended size
with the correct bore size and shape that matches the
grinder’s spindle.
2. Ensure the grinding wheel has a clean edge. Check
the grinding wheel for wear or chipping and replace

4. A large amount of sparks will be created when working
with a grinding wheel. Hold the tool so that sparks fly away
from you, bystanders or flammable materials. Have a fully
charged fire extinguisher present in the event of a fire.
5. Do not subject the grinding wheel to any lateral pressure as
it may damage the tool or cause it to kickback.
KICKBACK PRECAUTIONS
Kickback is a sudden reaction to a pinched or snagged cutting
accessory caught on the material. The material can be ejected
and inflict a serious injury on the user or a bystander. Kickback
can also damage the tool or workpiece.
Kickback can be avoided by taking proper precautions:
1. Maintain a firm grip on the material and position your
body and arms to allow you to resist a kickback. Kickback
can propel the material in the direction of the grinding
accessory’s rotation.
2. Use special care when working on corners, sharp edges or
flexible material. These workpieces have a tendency to
snag the grinding accessory.
3. Only use grinding accessories designed for the tool.
POWER TOOL PRECAUTIONS
1. Do not allow the tool to run without load for an extended
period of time, as this will shorten its life.
2. Do not cover the air vents. Proper cooling of the motor is
necessary to ensure normal life of the tool.
3. Avoid unintentional starting. Ensure the switch is off when
connecting to the power source.
4. Disconnect the power source before installing or servicing
the tool.
5. After making adjustments, make sure that any adjustment
devices are securely tightened.

6. Remove adjusting keys and wrenches before turning the
tool on. A wrench or a key that is left attached to a rotating
part of the tool increases the risk of personal injury.
7. Never force the tool. Excessive pressure could break the
tool, resulting in damage to your workpiece or serious
personal injury. If your tool runs smoothly under no load,
but does not run smoothly under load, then excessive
pressure is being used.
8. Do not touch an operating motor. Motors can operate at
high temperatures and can cause a burn injury.
9. Only use accessories that are specifically designed for use
with the tool. Ensure the accessory is tightly installed.
10. Only use an accessory that exceeds the No Load Speed
rating (see Specifications).
ELECTRICAL SAFETY
WARNING! To reduce risk of electric shock, be certain that the

8656852 10 IN. HEAVY-DUTY BENCH GRINDER V1.0
16 For technical questions call 1-800-665-8685
The bench grinder is equipped with one coarse grinding wheel
(36 grit) and one medium grinding wheel (60 grit). It is the
ideal tool for sharpening tools such as wood chisels, cold
chisels, planer blades, scissors, lawn mower blades, etc.
Because grinders can remove material rapidly, a freshly dressed
wheel and the amount of workpiece pressure applied to the
wheel are keys to efficient grinding. Use the following basic
guidelines to aid in working metals and avoid overheating.
1. Never force the workpiece against the grinding wheel.
Pressing too hard overheats the motor and prematurely
wears down the grinding wheel.
2. The grinding wheel rotates into the object being
sharpened.
3. Lay the workpiece against the tool rest and ease it into the
grinding wheel. Do not push the point or edge into the
wheel as it may catch and the workpiece may be pulled for
the user’s grasp.
4. Always keep the workpiece constantly moving against the
grinding wheel with light pressure and even motion.
5. Keep the workpiece cool by dipping it in a container of water.
6. Always use the face of the grinding wheel with the wheel
moving downward, into the object being worked.
7. Deburring the edge is done best by using the grinder to
pull burrs from the edge across the bevel angle. Note the
original bevel angle on the item to be sharpened and try to
maintain that angle.
8. Do not grind using the sides of a grinding wheel.
CARE & MAINTENANCE
1. Maintain the tool with care. A tool in good condition is
efficient, easier to control and will have fewer problems.
2. Inspect the tool fittings, alignment and power supply cord
periodically. Have damaged or worn components repaired or

V1.0 10 IN. HEAVY-DUTY BENCH GRINDER 8656852

replaced by an authorized technician. Only use identical
replacement parts when servicing.
2.1 Reposition the tool rest closer to the wheel face as it wears
away. The gap between the wheel face and the tool rest
should not be greater than 1/8 in. Replace the worn wheels
when the 1/8 in. maximum gap cannot be maintained.
3. Follow instructions for lubricating and changing accessories.
4. Only use accessories intended for use with this tool.
5. Maintain the tool’s labels and name plates. These carry
important information. If unreadable or missing, contact
Princess Auto Ltd. for replacements.
6. Wheels should be dressed periodically to maintain grinding
efficiency, especially if they become clogged from grinding
soft metals. Use a grinding wheel dresser to restore the
wheel’s original shape.
6.1 Dress the grinding wheel face only. Dressing the wheel
sides can cause it to become too thin for safe use.
7. Keep all parts in working order. Check to determine that
the guard or other parts will operate properly and perform
their intended function.
8. A guard or other part that is damaged should be properly
repaired or replaced. Do not perform makeshift repairs.
9. Disconnect tool when changing grinding wheels.
10. Replace a cracked wheel immediately and use only the
flanges supplied with the grinder.
11. Replacement wheels must have a minimum rated speed of
1,725 RPM and a maximum diameter of 10 in.
WHEEL DRESSING
A grinding wheel may become unbalanced due to irregular
wear or it is loaded with ground material. The grinding wheel
must be trued and dressed.

8656852 10 IN. HEAVY-DUTY BENCH GRINDER V1.0
18 For technical questions call 1-800-665-8685
Truing or dressing the wheel is best done using a star-wheel
dresser, a silicon carbide stick type dresser or a diamond faced
dressing tool.
Dress the wheel by moving the dresser forward on the tool rest
until it just touches the highpoint on the face of the wheel, then
dress the wheel by moving the dresser back and forth across
the wheel face.
Repeat this procedure until the face of the grinding wheel is
clean and the corners of the wheels are square.
CHANGING THE GRINDING WHEELS
WARNING! Use only grinding wheels rated for 1,725 RPM or higher
with a 1 in. arbor hole and the appropriate sized bushing. Never
use a grinding wheel rated lower than 1,725 RPM or attempt to
machine an undersized wheel to fit the arbor. The grinding wheel
may fragment during grinding and cause an injury.
1. Prevent the shaft from rotating by placing a wedge
between the wheel and the tool rest.
2. Remove the five screws (#1) attaching the protective side
cover to the grinder. Remove the side cover.
3. Loosen the hex nut. The left nut (#6) has a left-hand
thread. The right nut (#25) has a right-hand thread.
4. Remove the hex nut, the flange (#5) and the old wheel.
5. Install the replacement wheel and outer flange on the shaft.
Make sure the wheel is a tight fit on the shaft.
6. Replace the arbor nut and tighten enough to drive the
wheel and prevent slippage. Excessive tightening can cause
the wheel to crack prior to or during operation.
7. Replace the side cover. Reinsert the five screws and tighten
the side cover in place.
8. Adjust the tool rest and spark shield guard distance from
the grinding wheel. Maintain a separation of 1/8 in. or less
as the wheel diameter decreases from use.
