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.

W ARNING: Do not operate this dust control unit until you are sure that you are completely familiar

with the safe operation of the dust control unit. 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 dust control unit or this manual.

W ARNING: Do not use dust control unit in the presence of potentially combustible materials. Keep all

combustible materials and flammable vapors away from dust control unit.

W ARNING: Do not operate the dust control unit/grinder with the dust bag removed. Debris that may

come from an open exhaust outlet can be a hazard to nearby persons or equipment.

WARNING: Prevent electrical shock hazard and accidental machine operation. Always disconnect dust

control unit from the power source before servicing, changing dust bag or maintenance.

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.

W ARNING: 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.

W ARNING: Don’t use in dangerous environment. Don’t use dust control units in damp or wet

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.

W ARNING: Check damaged parts. Check for alignment of moving parts, binding of moving parts,

breakage of parts, mounting, and any other conditions that may affect its operation.
Damaged parts should be properly repaired or replaced.

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.
T able 1 shows the correct wire size to use depending on cord length and nameplate ampere
rating. If i n doubt, use the next heavier gauge. The smaller the AWG gauge number , the heavier
the cord.

W ARNING: Dust created during grinding, 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.

9. Attach dust bag to elbow with clamp supplied.

Electrical Instructions

Single phase dust control units are rated dual voltage. Some single phase dust control units

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 dust control unit is
reconnected. For your safety, be certain dust control unit is properly grounded. Table 1
indicates the minimum wire size. Be sure to comply with NEC and local wiring codes.

Three phase dust control units are normally dual voltage and must be wired for the proper
voltage and rotation direction (connections are inside conduit box). Connect phase sequence
so that the wheel moves down toward top surface of tool rest as viewed from front of dust
control unit. Wheel must rotate toward tool rest. Be sure all electrical connections are secured
and properly insulated. For your safety, be certain dust control unit is properly grounded.
Table 1 indicates the minimum wire size. Be sure to comply with NEC and local wiring codes.
