1MN906

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.

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 or before performing maintenance. Electrical shock can

cause serious or fatal injury. Only qualiﬁed personnel should install, maintain or troubleshoot this equipment.

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 buffer. Do not use ordinary

eyeglasses. Also use face or dust mask if bufﬁng 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: Do not use in dangerous environment. Do not 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: Do not reach over buffer during operation. Keep proper footing and balance at all times. A rotating wheel

can catch an article of clothing and cause personnel injury. Always keep hands at least 2 inches from wheels.

WARNING: Check damaged parts. Before further use of the buffer, carefully check 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.

WARNING: When starting a buffer for the ﬁrst time, or after installing a replacement bufﬁng 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.

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 bufﬁng, 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. Padlock equipment or work area when not in use.

WARNING: Never leave buffer running unattended. Always turn power off after use.

Caution: Do not force buffer. It will do the job better and safer at the feed rate for which it was designed.

Caution: Maintain buffer with care. Keep buffer clean for best and safest performance.

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 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.

Use soft cloth wheels only on buffer. Buffer is not designed to be used with hard wheels or wire wheels.

This buffer is supplied without guards or a dust hood. Depending on the location and installation of the buffer, the

type of cloth wheel and compound used for an application, the piece to be polished, and other factors, the end user

of this buffer may determine that use of a guard or dust hood around the cloth wheel is appropriate. Baldor Electric

Company does not include a guard with this buffer. The end user is responsible to determine if any type of guard

or dust hood is appropriate for the end user’s use of the buffer. The end user may contact Baldor Electric Company

with any questions.

If machine should be damaged, discontinue using the buffer until the repairs are made.

Figure 1 Typical Buffer

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 buffer for the ﬁrst time, or after installing a replacement bufﬁng 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, rst bolt pedestal securely to oor 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 bufng wheel (see Figure 1).

a. Remove arbor nut, spacer and outer wheel ange.

b. Place the buffer wheel on the arbor.

c. Install the outer wheel ange, spacer and arbor nut.

d. The arbor nut should be tightened just enough to prevent wheel slippage on the arbor and the

vinyl arbor nut cover must be in place.

When starting buffer for the rst 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 rst 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.

Grounding Instructions

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.

1. All grounded, cord-connected buffers:

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to

reduce the risk of electric shock. This buffer is equipped with an electric cord having an equipment-grounding

conductor and a grounding plug.

The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all

local codes and ordinances. Do not modify the plug provided. If it will not t the outlet, have the proper outlet

installed by a qualied electrician.

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The “Green”

insulated wire (with or without yellow stripes) is the equipment-grounding conductor. If repair or replacement of

the electric cord is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with

a qualied electrician or serviceman if the grounding instructions are not completely understood, or if in doubt

as to whether the tool is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the

tool’s plug. Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected buffers intended for use on a supply circuit having a nominal rating less than 150

volts. This buffer is intended for use on a circuit that has an outlet that looks like the one illustrated in

Figure A or B.
