Instruction Manual For Baldor Buffers
SAFETY NOTICE:
WARNING statements describe conditions that may lead to personnel injury including potentially
fatal injuries if the machine is not properly used and warnings are not properly followed.
Caution statements describe conditions that may lead to equipment damage.
Electrical shock can cause serious or fatal injury. Only qualified personnel should install,
maintain or troubleshoot this equipment.
WARNING: Do not operate this buffer until you are sure that you are completely familiar with the safe
operation of the buffer, 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 buffer or this manual.
WARNING: Prevent electrical shock hazard and accidental machine operation. Always disconnect
buffer from the power source before servicing, changing accessories (such as wheels,
tool rest, spark arrestor, etc.) or before performing maintenance.
WARNING: Use a holder when practical. It’s safer than using your hand and it keeps hands away from
wheel. Always keep hands at least 2 inches from wheels.
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 buffer. 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: Remove adjusting keys and wrenches from this product after use. Check to see that keys
and adjusting wrenches are removed from buffer 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 buffers 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: Check damaged parts. Before further use of the buffer, 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: 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 debris in the wheel may be thrown out during the
first moments the machine is in operation.

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.

designed.
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.
Unsuitable accessories or attachments added to this buffer may introduce hazards.
Baldor accessories and attachments are specifically designed to be used with the buffer.
Accessories or attachments obtained from another source may cause hazards. Consult the
manufacturer before use.
Tool rests are not recommended to be used with a buffer. There is the possibility of the
work piece becoming caught in the cloth wheel and pulling the operator’s hand into the
machine or hurling the work piece away from the machine in a hazardous manner, or both.
Use soft cloth wheels only on buffer. When hard (grinding) wheels or wire wheels are
used on a buffer, the operator or nearby personnel will not be protected against wheel failure
which can result in serious injury.
Use soft cloth wheels marked for safe operations at or over the maximum RPM rating
on this buffer. Using a wheel rated at a lower RPM than the machine is rated can cause a
hazardous condition and result in short wheel life.
Buffer is not designed to be used with hard wheels or wire wheels. Bench grinders and
grinder−buffers having wheel guards are available for such use and protect the operator from
wheel breakage. As wheel breakage is an extremely hazardous condition, under no
circumstances should a buffer be used with hard wheels or wire wheels.
This buffer is supplied without guards. Operator safety may require guards and other
suitable safety devices or procedures. These may be specified in safety codes and should be
provided for each polishing application. These are are neither provided by Baldor Electric
Company nor are the responsibility of Baldor Electric Company. Safety devices are the
responsibility of the end user.
If machine should be damaged, discontinue using the buffer until the repairs are made.

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 debris in the wheel may be thrown out during the
first moments the machine is in operation.
3. Mount buffer on solid bench. The buffer must be securely bolted to a rigid mounting
surface. If a pedestal is used, first bolt pedestal securely to floor and then bolt buffer to
pedestal.
4. Check buffer nameplate to make certain the rating is correct for the power source,
voltage and frequency. See electrical and grounding instructions for electrical service
connection.
5. Install soft cloth buffing wheel (see Typical Buffer Figure)
a. Remove arbor nut, spacer and outer wheel flange.
b. Place the buffer wheel on the arbor.
c. Install the outer wheel flange, spacer and arbor nut.
d. The arbor nut should be tightened just enough to prevent the wheel slipping on the
arbor and the vinyl arbor nut cover must be in place.
When starting buffer for the first time or after installing replacement wheel, it is most important
that the operator stand aside for at least one minute. Debris in the wheel may be thrown out
during the first moments the machine is in operation.
Electrical Instructions
Single phase buffers are equipped with cord and grounding type plug for 115 volts. To use
with a different voltage, see instructions provided to make wiring changes. All attachment
plugs and any receptacles must be replaced with devices rated for the voltage for which the
buffer is reconnected. Table 1 indicates the minimum wire size. Be sure to comply with NEC
and local wiring codes.
