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
