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.
