ASSEMBLY INSTRUCTIONS/OPERATIONS
11)The sawing process on many work surface materials can produce sparks, dust and other foreign particle contamination.
DANGER
SPARKS PRODUCED BY THE ACTION OF THE DIAMOND BLADE 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.
12)Dust and other particle contamination can be controlled by the following methods:
a)The Crack Saw is equipped with a 3 inch outside diameter vacuum tube adaptor located at the front of the machine. An industrial type vacuum system can be attached to the Crack Saw 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 26.
CAUTION
Use of a vacuum system with the Crack Saw will not totally eliminate or provide 100 per cent dust and other particle contamination removal from the atmosphere and work surface. Secondary dust and other particle contamination removal procedures from the atmosphere and work surface will normally be required.
FIGURE 26
DANGER
ALWAYS UTILIZE A VACUUM SYSTEM 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)A water stream directed to the blade can be an effective method of reducing dust effects and increasing service life at the same time. The optional RCCWC Wet Sawing Kit can be installed to direct a continuous stream of water to both sides of the diamond blade. FIGURE 27. The kit includes a standard globe type valve to control water feed rates and is directly coupled to a water hose. Potential negative effects of this procedure is that the water and slurry mixture will require additional time for disposal and proper drying before
crack filling work can be initiated. Under specific circumstances, the resulting slurry mixture can also be classified as a hazardous material, requiring proper disposal procedures.
13)The Crack Saw is equipped with a quick change height lever designed to raise the diamond blade clear
