The quick-change height lever is intended to provide
a fast method to raise the blade for the following
reasons:
a) When the sawing process is completed for a
random crack, the blade can be quickly raised from
the work surface and the machine moved by the
operator to another random crack on the job site.
Lowering the quick change lever to the full down
position will return the diamond blade to the specific
depth as originally determined by the height
adjustment lever.
FIGURE 29. The quick change height lever is
intended to produce uniform sawing depths for any
specific job application.

DANGER
EXERCISE EXTREME CAUTION WHEN MOVING
THE CRACK SAW ON THE JOB SITE WITH THE
POWER SOURCE RUNNING AND THE QUICK
CHANGE HEIGHT LEVER OVER CENTER TO ITS
REAR MOST (UP) POSITION. IN THIS
OPERATING CONFIGURATION, THE DIAMOND
BLADE CAN COME IN DIRECT CONTACT WITH
FOREIGN OBJECTS AND THE WORK SURFACE
ITSELF. THIS OCCURRENCE CAN
SUBSTANTIALLY REDUCE MACHINE CONTROL
AND PRODUCE FLYING OBJECTS, RESULTING
IN PROPERTY DAMAGE AND/OR PERSONAL
INJURY. CAUTION ALL ONLOOKERS
REGARDING THE POSSIBILITY OF FLYING
OBJECTS.
b) If the sawing process overloads the power source
to cause complete stoppage, the diamond blade can
be readily raised by the operator to clear the work
surface before the power source is restarted.
DANGER
DO NOT START AND/OR RESTART THE POWER
SOURCE WITH THE DIAMOND BLADE IN
DIRECT CONTACT WITH THE WORK SURFACE.
BEFORE STARTING AND/OR RESTARTING THE
POWER SOURCE, RAISE THE QUICK CHANGE
HEIGHT LEVER OVER CENTER TO ITS REAR
MOST (UP) POSITION TO ALLOW THE DIAMOND
BLADE TO COMPLETELY CLEAR THE WORK
SURFACE. IF THIS ACTION DOES NOT
COMPLETELY RAISE THE DIAMOND BLADE
FROM THE WORK SURFACE, DETERMINE THAT
