WARNING: Do not operate this grinder until you are sure that you are completely familiar with the safe operation of the
grinder, all accessories and safety equipment. Improper use can lead to severe injury. This manual defines
proper use of this equipment. Before using this equipment for any other use, please consult Baldor. Contact
Baldor if you do not understand any procedure or operation concerning this grinder or this manual.
WARNING: Prevent electrical shock hazard and accidental machine operation. Always disconnect grinder from the
power source before servicing, changing accessories (such as wheels, tool rest, spark arrestor, etc.) or
before performing maintenance.
WARNING: Avoid accidental starting. Make sure switch is in “OFF” position before connecting to power source.
WARNING: Be sure the system is properly grounded before applying power. Do not apply power before you ensure that
grounds are connected. Electrical shock can cause serious or fatal injury. Follow the National Electrical Code
(NEC) and local codes for the safe installation of this equipment.
WARNING: Always use safety glasses with side shields (or full face shield) when operating grinder. Do not use ordinary
eyeglasses. Also use face or dust mask if cutting operation is dusty.
WARNING: Unsuitable accessories or attachments added to this machine can create hazards. Baldor accessories
are specifically designed to be used with this grinder. Use accessories or attachments only in the proper
intended manner. Accessories or attachments obtained from another source may cause hazards. Consult the
manufacturer before use.
WARNING: Keep guards in place and in working order. Guards are design to prevent injury. Never operate this equipment
if a guard is damaged, missing or improperly installed.
WARNING: Remove adjusting keys and wrenches from this product after use. Check to see that keys and adjusting
wrenches are removed from grinder before turning it on. Projectiles can cause severe injury to yourself or
others.
WARNING: Keep work area clean and well lighted. Clutter and poor lighting invites accidents.
WARNING: Don’t use in dangerous environment. Don’t use grinders in damp or wet locations, or expose them to rain.
Electrical shock can cause serious or fatal injury. Follow the National Electrical Code (NEC) and local codes
for the safe installation of this equipment.
WARNING: Do not wear loose clothing, neckties, rings, bracelets, or other jewelry to get caught in moving parts. Nonslip
footwear is recommended. Wear protective hair covering to contain long hair.
WARNING: Don’t over reach. Keep proper footing and balance at all times. A rotating wheel can catch an article of
clothing and cause personnel injury.
WARNING: Secure work. Use clamps to secure the work piece when practical. It’s safer than using your hand and it
keeps hands away from wheel.
WARNING: When starting a grinder for the first time, or after installing a replacement grinding wheel, it is most important
that the operator stand aside for at least one minute of rotation at full speed. This is the correct practice
since grinding wheels can disintegrate if they have received damage during shipping or handling.
WARNING: Check damaged parts. Before further use of the grinder, a guard or other part that is damaged should
be carefully checked to assure that it will operate properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions
that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.
WARNING: Never install a wheel that is damaged, such as a chip or crack on any surface. A damaged wheel can
disintegrate while rotating at a high RPM or when work is placed against the wheel. This can severely harm
the operator or others in the area.
WARNING: Use proper extension cord. Make sure your extension cord is in good condition. When using an extension
cord, be sure it is rated for the voltage and current rating of your product. An undersized cord will cause a
drop in line voltage resulting in loss of power and overheating.
Table 1 shows the correct wire size to use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the AWG gauge number, the heavier the cord.
WARNING: Dust created during grinding, sawing, power sanding, drilling, and other activities may contain chemicals
known to the State of California to cause cancer, birth defects or other reproductive harm.
WARNING: Keep children and visitors away. Remove starter keys turn off master switches. Padlock equipment or work
area when not in use.
WARNING: Never leave grinder running unattended. Always turn power off after use.
Caution: Don’t force grinder. It will do the job better and safer at the feed rate for which it was designed.
Caution: Use right tool. Don’t force tool or attachment to do a job for which it was not designed.
Caution: Maintain grinder with care. Keep grinder clean for best and safest performance.

SAFETY NOTICE Continued
Always use safety glasses with side shields (or full face shield) when operating grinder.
Do not use ordinary eyeglasses. Also use face or dust mask if cutting operation is dusty.
Do not overtighten wheel mounting screws. A damaged grinding wheel can disintegrate in all directions.
Overtightening wheel mounting screws can stress the grinding wheel and cause it to disintegrate during operation.
Wheel mounting screws should be tightened just enough to prevent grinding wheel from slipping on shaft when
grinding. Use only anges furnished with this grinder. The anges furnished with the grinder are designed to grip the
grinding wheel without introducing excessive stresses in the wheel.
Replace a cracked or chipped wheel immediately. A cracked wheel will disintegrate when operated, causing a
hazard to operator and nearby personnel. If a wheel has a chip or crack on any surface, do not use it.
Maintain 1/8 or less clearance between tool rest and wheel. This clearance is necessary to prevent the work
piece from becoming wedged between the wheel and tool rest and restricting nip areas in the machine.
Grind on rim face (side) of wheels only. Grinding on outside diameter of wheel weakens the wheel and may cause
wheel breakage.
Use wheels rated at or over 3600 RPM.

Installation When you receive your unit, there are several things you should do immediately.
1. Observe the condition of the shipping container and report any damage immediately to the commercial carrier
that delivered the product.
2. Verify that the part number you received is the same as the part number listed on your purchase order.
WARNING: When starting a grinder for the first time, or after installing a replacement grinding wheel, it is most important
that the operator stand aside for at least one minute of rotation at full speed. This is the correct practice
since grinding wheels can disintegrate if they have received damage during shipping or handling.
3. Mount grinder on solid bench. The grinder must be securely bolted to a rigid mounting surface. If a pedestal is
used, rst bolt pedestal securely to oor and then bolt grinder to pedestal.
4. Check grinder nameplate to make certain the rating is correct for the power source, voltage and frequency. See
electrical and grounding instructions for electrical service connection.
WARNING: Never install a wheel that is damaged, such as a chip or crack on any surface. A damaged wheel can
disintegrate while rotating at a high RPM or when work is placed against the wheel. This can severely harm
the operator or others in the area.
5. Inspect each Wheel
Carefully inspect the grinding wheels for damage. Never install a wheel that shows any sign of damage such as
a chip or crack on any surface. A damaged wheel can disintegrate while rotating at a high RPM or when work is
placed against the wheel. This can severely harm the operator or others in the area.
Note: Baldor catalog items #500 and #510 are supplied with mushroom head machine screws. Baldor catalog items
#522 and #532 Diamond wheel grinders are supplied with both types of hardware.
WARNING: Never install a wheel that is damaged, such as a chip or crack on any surface. A damaged wheel can
disintegrate while rotating at a high RPM or when work is placed against the wheel. This can severely harm
the operator or others in the area.
6. Install the Grinding Wheels (see Figure 1).
a. Plate Mounted Wheels
Remove the machine screws from the wheel ange. Attach the wheel to the wheel ange using
four 5/16-18 mushroom head machine screws.
b. Diamond Wheels
Remove the machine screws from the wheel ange. Attach the wheel to the wheel ange using
four 1/4-20 at head machine screws.

7. Carefully inspect each wheel for damage. If damaged, remove and discard the wheel and install a new wheel.
Never use a defective wheel.
8. Install the Arbor/Wheel Mounting Screw Covers:
Tool grinders are supplied with covers for the arbor nut and wheel mounting screws (see Figure 2). There are
two sizes. Smaller diameter covers are for plate mounted wheels with 4−inch diameter center. Larger diameter
covers are for diamond wheels with 4 1/2−inch diameter center. Carbide and diamond wheel tool grinders are
supplied less grinding wheels. After installing the desired grinding wheels, tighten wheel mounting screws and
install arbor/wheel mounting screw covers.
a. Select the arbor/wheel mounting screw cover that is correct for the wheel center diameter.
b. Center the inner hub of the cover over the shaft arbor nut.
c. Using a light mallet (rawhide or plastic head type), lightly tap the cover over the arbor nut. The cover should
seat rmly on the arbor nut with no cocking or wobbling around the outside diameter of the cover.
d. To remove the arbor/wheel mounting screw covers, use a at blade tool such as a straight blade
screwdriver to lift the edge of the cover. Go around the complete circumference of the cover, lifting gently
around the edge until it comes loose from the arbor nut.
e. Remove the wheel mounting screws to replace the wheel. Never loosen or remove the shaft arbor nut.
f. Replace the wheel and wheel mounting screws. Follow the instructions supplied with the new grinding
wheel. Install the arbor/wheel mounting screw cover removed in steps “a” through “c”.

3).
a. Position table so the studs are in the slotted holes of the rocker (location A in Figure 3).
b. Install washers and nuts provided to secure the tool table to the rocker.
c. Adjust table for about 1/16” clearance between the table and rim face of the grinding wheel then tighten
the nuts.
d. Repeat steps “a” through “c” for the other tool table.
10. Install the Water Trays. Each tray has two mounting holes that slide onto two pins on its rocker.
a. Slide the water tray onto the mounting pins located below the tool table and between the front and rear
surfaces of the rocker.
b. Be sure the tray is securely seated on the pins so you can see the ends of the pins in the mounting holes.
