WARNING: The MC-800 maximum blade operating speed is 5,850
rpm as labeled on the blade guard. Use only dry cut diamond blades
rated higher than 5,850 rpm safe operating speed. Do not use a blade
rated for less than 5,850 rpm. Do not use a blade that is not a dry cut
diamond blade. Using a non dry cut diamond blade or a blade rated
below 5,850 rpm could result in severe blade failure, personal injury
or death. See Figure 8 and Figure 9. Never cut material for which
the blade was not designed. Check blade manufacturer's guidelines
on material to be cut. Never operate a blade in the wrong rotation
direction. Verify blade direction when changing blades. The MC-800 is
designed to cut in a straight line. Never attempt to cut any pattern or
follow any joint that is not a straight line.

AVOID STATIC ELECTRICITY RISK
WARNING: Ultra-Low Sulfur Diesel (ULSD) poses a greater static ignition
hazard. Consult with your propane supplier to ensure the delivery system
is in compliance with fueling standards for proper grounding and bond-
ing practices. Maintaining a discharge strap must be connected to any
U.S.SAWS vacuum at all times when equipment is being used.
WARNING: Exhaust gas engines contains dangerous carbon monox-
ide. Breathing it can cause unconsciousness and even kill you. Always
operate in a well-ventilated area. Do not operate in areas where exhaust
fumes could accumulate without wearing appropriate respiratory protec-
tion. Consult your employer and OSHA regarding use of appropriate
respirator for dangerous carbon monoxide gases. See Figure 7.
