OPERATING INSTRUCTIONS
Please review the operator’s manual for the CC8000 rider saw for additional
instructions (Part #1800452).
CURBCUTTER CONTROLS :
Two sets of controls allow positioning the blade from either the drivers seat or
from the front of the unit. Both sets are always active. As one faces either set
of valves, the order of control from left to right is: Vertical, Horizontal, Roll,
and Pitch. Speed is controlled by both engine speed and how far the levers are
pushed. The levers will automatically return to the center position. Note: The
cylinder driven roll motion is much quicker than the others at full flow.
BRAKE / PITCH CONTROL
A hydraulic brake caliper and rotor are mounted at the pitch control shaft to
further lock the pitch position. The caliper hydraulic pressure is supplied by
using a line at the raise/lower cylinder. The cylinder is disconnected when the
curb cutter is mounted. One of the cylinder raise/lower control buttons will
activate and lock the brake on, and the other will depressurize it. A gage shows
when the brake is energized. The brake should be applied only after the pitch
position is confirmed. If the brake is not deactivated, pitch adjustment will be
difficult or impossible. The rotor should be clean and dry for maximum holding
power.
BLADE SIZE
Blade guards are available for 24, 30, and 36 inch blades. With the 30 inch
being standard. The 24 inch blade has less reach but is more rigid and may give
a smoother cut. The 36 inch blade allows more reach but has more flex.
The larger blade is also more likely to interfere with the crown of the road and
prevent lowering the blade to the desired level. A high crown or other road
conditions may require the use of the 24 inch blade to avoid interference.
