RCC130H-CRACK SAW OPERATION AND PARTS MANUAL REV #1 (11/18/04) PAGE 22
ASSEMBLY INSTRUCTIONS/OPERATIONS
PROPERTY DAMAGE AND/OR PERSONAL
INJURY. EXCESSIVE LEVELS OF CARBON
MONOXIDE CAN CAUSE DEATH.
1) The Crack Saw is of a downcut type design as
viewed by the operator. The diamond blade is
intended to rotate toward the operator to enhance
visibility and overall productivity while following a
random crack. The down cut action results in a "self
propelled" effect toward the operator that
substantially enhances machine control and reduces
fatigue as long as the diamond blade does not come
in direct contact with a protruding obstruction from
the floor. Direct contact with such an obstruction can
result in rapid and jerky directional movement of the
machine. In most operating situations, direct contact
with a protruding obstruction from the floor will result
in serious damage to the diamond blade. This
occurrence may not allow the operator to remain in
proper control of the machine.
DANGER
ALWAYS MAINTAIN PROPER CONTROL OF THE
CRACK SAW. IF AN OPERATOR LOOSES
CONTROL OF THE MACHINE, A "RUNAWAY"
CRACK SAW CAN RESULT IN PROPERTY
DAMAGE AND/OR PERSONAL INJURY.
BECAUSE OF THE UNIQUE OPERATING
CHARACTERISTICS OF THE CRACK SAW,
THERE IS NO PROVISION FOR THE ELECTRIC
MOTOR/ENGINE TO AUTOMATICALLY STOP IF
THE OPERATOR FAILS TO MAINTAIN PROPER
CONTROL.
DANGER
WHEN OPERATING THE CRACK SAW ON
ABOVE GROUND FLOOR LEVELS, EXERCISE
EXTREME CAUTION TO PREVENT LOSS OF
CONTROL THAT COULD ALLOW THE MACHINE
AND/OR OPERATOR TO FALL DOWN TO
LOWER LEVELS. SUCH AN OCCURRENCE CAN
RESULT IN PROPERTY DAMAGE AND/OR
PERSONAL INJURY.
2) The crack sawing process is not intended to
require additional weight to be applied to the
machine for the purpose of increasing productivity
and/or stability. No provision for attaching weight is
made.
DANGER
DO NOT OPERATE THE CRACK SAW WITH
ADDITIONAL WEIGHT APPLIED DIRECTLY TO
THE MACHINE TO INCREASE PRODUCTIVITY
RATES AND/OR MACHINE STABILITY.
PROPERTY DAMAGE AND/OR PERSONAL
INJURY CAN RESULT. PRODUCTIVITY AND/OR
STABILITY RELATED PROBLEMS SHOULD BE
DIRECTED TO SPECIFIC MECHANICAL
PROBLEMS WITH THE MACHINE,
OPERATIONAL PROCEDURES AND/OR
SPECIFIC MECHANICAL PROBLEMS
ASSOCIATED WITH THE DIAMOND BLADE.
CONTACT THE CUSTOMER SERVICE
DEPARTMENT FOR ASSISTANCE. THERE IS NO
CHARGE FOR THIS SERVICE.
3) The Crack Saw is designed to be pulled toward
the operator during normal operation to enhance
visibility and overall productivity while the blade
follows a random crack.
CAUTION
Operating the Crack Saw by pushing it forward
will substantially reduce overall productivity and
reduce operator control. The diamond blade will
deposit dust and residue materials under the
feet of the operator. This configuration will not
allow the machine to be utilized with a vacuum
system. This occurrence can also reduce
operator stability on the work surface and lead
to property damage and/or personal injury.
4) Position the Crack Saw over the random crack
with the diamond blade directly above and parallel
with the crack direction. Align the front casters of the
machine parallel with the crack direction to maximize
operator control at the start of the sawing process.
