Operation
When operating...
SEVERE ELECTRIC SHOCK HAZARD
Electric: Keep the extension cord clear of machine
travel path.
Adjust the height of the cutter drum. Set the depth of cut
to allow the cutters to go through only the materials to be
removed. Make certain that the drum is positioned to
where only the cutters strike the work surface, and that
the drum assembly never comes in to contact with the
work surface. The cutter tips alone should strike the
work surface (1/8" to 1/4" maximum depth per removal
pass on new cutters). The drum will not survive work
surface contact.
Cutting too deep will cause premature wear to cut-
ters, shafts, drum and other components.
Remove materials in several passes rather than one
deep pass. Several tests will show the best, most
appropriate cutter depth. Use a forward/backward
pattern to achieve your desired finish.
When the job is complete, or the operator wants to cease
work, raise the drum above the work surface by pressing
home button on DCS control.
•
For gas units, stop the machine with the key switch
or power switch.
•
For propane units, stop machine with the key
switch or power switch, then close the propane
supply valve.
•
For electric units, stop machine by turning motor
power switch OFF, and unplug the machine from
the electrical source.
The drum assembly must be removed daily and
inspected for drum wear, hole elongation and possible
weld separation. Replace the cutter shafts every 40
hours, or prior to any drum wear. If the drum's center
holes are elongated, order another Graco cutter drum.

NOTICE
Hydrostatic Drive Operation
Engine/motor must be warmed up and at desired speed.
Verify the Forward/Reverse Control Lever is in the
neutral (N) position. Lower the unit to raise the carriage
wheels off the work surface and set the unit onto the
drive wheels. The Forward/Reverse Control Lever
should be in the neutral (N) position and the wheels
should not be turning. At this point the unit can be
propelled forward or reverse by pressing down on the
Control Lever and moving the Control Lever either
forward or backward.
The "live" axle will help move the unit in a straight line.
However, keep both hands on the handle for safe
operation and minor directional corrections.
