DFG-SERIES SURFACE GRINDERS OPERATION AND PARTS MANUAL REV #4 (05/28/09) PAGE 35
ASSEMBLY INSTRUCTIONS/OPERATIONS
5) The grinding process on many work surface
materials can produce sparks, dust and other
foreign particle contamination.
DANGER
SPARKS PRODUCED BY THE ACTIONS OF
MULTI-ACCESSORY OPTIONS AGAINST THE
WORK SURFACE (FOR EXAMPLE: STRIKING
ANCHOR BOLTS) MAY COME IN CONTACT
WITH MATERIALS THAT CAN RESULT IN A FIRE
AND/OR EXPLOSION. THIS OCCURRENCE CAN
RESULT IN PROPERTY DAMAGE AND/OR
PERSONAL INJURY.
DANGER
THE CREATION OF DUST AND OTHER FOREIGN
PARTICLE CONTAMINATION FROM THE
OPERATIONAL PROCESS CAN RESULT IN
PROPERTY DAMAGE AND/OR PERSONAL
INJURY. FOR SUCH OPERATING CONDITIONS,
ALWAYS WEAR A NIOSH/MSHA APPROVED
DUST/MIST RESPIRATOR. CONSULT
APPLICABLE OSHA REGULATIONS FOR
SPECIFIC INFORMATION.
6) Dust and other particle contamination can be
controlled by the following methods:
a) The SURFACE GRINDER is equipped with
a 1-1/2, 2 or 3 inch outside diameter vacuum
tube adaptor located at the rear of the
machine. An industrial type vacuum system
and front shield assembly can be attached
to the SURFACE GRINDER to
remove/control dust and other particle
contamination from the work surface. A hose
clamp is sometimes required to properly
secure the vacuum hose to the vacuum
tube. FIGURE 39.

DANGER
ALWAYS UTILIZE A VACUUM SYSTEM
DESIGNED TO OPERATE WITHIN THE SPECIFIC
JOB SITE REQUIREMENT. DUST MATERIAL CAN
MEET CLASS II OR CLASS III SPECIFICATIONS
OF THE NATIONAL ELECTRIC CODE® FOR
HAZARDOUS LOCATION CLASSIFICATIONS.
CONSIDERATION MUST ALSO BE GIVEN TO
THE CREATION OF HAZARDOUS TYPE
MATERIALS REQUIRING SPECIFIC DISPOSAL
PROCEDURES. DETERMINE THAT THE VACUUM
SYSTEM IS PROPERLY DESIGNED TO OPERATE
WITHIN THESE ATMOSPHERES. CONSULT
CURRENT NATIONAL ELECTRIC CODE®, OSHA
AND ENVIRONMENTAL PROTECTION AGENCY
REGULATIONS FOR SPECIFIC INFORMATION.
b) Water/sand slurry mixture applied directly to
the work surface can be an effective method
of reducing the effects of grinding and other
material removal processes. This method
can be a productive alternative when
removing adhesives containing asbestos. A
negative effect of this method is that the
water/sand slurry mixture can be classified
as a hazardous material, requiring proper
disposal procedures.
7) Normal usage of the SURFACE GRINDER will
allow the build-up and accumulation of work
surface materials on interior surfaces. It is highly
recommended that both the interior and exterior
surfaces be properly cleaned after the
completion of each usage.
CAUTION
Failure to properly clean the interior surfaces of
the SURFACE GRINDER can result in dried
material build-up and accumulation directly
affecting bearing service life.
DANGER
EXERCISE EXTREME CAUTION WHEN
UTILIZING ANY SOLVENT TO REMOVE
ACCUMULATED MATERIALS FROM THE
SURFACES OF THE MACHINE AND RELATED
COMPONENTS. MANY SOLVENTS ARE
FLAMMABLE. DO NOT SMOKE OR INTRODUCE
FLAME IN THE WORK AREA. PROVIDE
ADEQUATE VENTILATION AND WEAR PROPER
SAFETY APPAREL.
