Instruction Manual For Baldor Dust Control Units
Models DC7, DC7–3, DC8, DC8–3, DC10, DC10–3, DC12, DC12–3 and DC14–3.
For use on Grinders mounted to GA16 and GA20 pedestals
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
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: 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.

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.

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 dust control units:
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 dust control unit 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 fit the outlet, have the proper outlet installed by a
qualified 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 qualified 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 dust control units intended for use on a supply circuit having
a nominal rating less than 150 volts:
This dust control unit is intended for use on a circuit that has an outlet that looks like the
one illustrated n Figure A. The tool has a grounding plug that looks like the plug
illustrated in Figure A. A temporary adapter, which looks like the adapter illustrated in
Figures B and C, may be used (except in Canada) to connect this plug to a 2–pole
receptacle as shown in Figure B if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly grounded outlet can be installed
by a qualified electrician. The green–colored rigid ear, lug, etc. extending from the
adapter must be connected to a permanent ground such as a properly grounded outlet
box.
3. Permanently connected dust control units:
This dust control unit should be connected to a grounded, metal, permanent wiring
system; or to a system having an equipment–grounding conductor.

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.
Before operating the dust control unit, be sure that all parts are in place. Check the grinder
that is connected to the dust control unit to be sure it is in safe operating condition. Replace
any damaged or missing parts. Do not operate grinder or dust collector with damaged or
missing parts.
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.
The dust control unit is for collecting dry material. Many materials in dust form are
combustible. Check material safety data sheet. If material is potentially combustible, do not
use with this 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.
Air Flow Control
The air flow is directed to the wheels by adjusting the air control valves. To meet OSHA
requirements, it is necessary to direct the air flow to the wheels, see Figure D. For “open”
and “closed” position of air control valves, see Figure E. Close the air control valve to the
unused wheel, open the air control valve to the wheel being used.
