Operation
3A5578C 17
NOTE: On harder surfaces, it may be best to make
several passes in increments of 1/32 in. (0.8 mm) to get
to the desired depth.
• Make certain that the drum is positioned to where
only the cutter tips strike the surface, and that the
drum assembly never comes into contact with the
substrate. The cutter tips alone should strike the
surface.
• The drum will not withstand substrate contact.
Contacting the removal surface too deeply will
cause premature wear to cutters, shafts, drum and
other components. The correct depth setting is
indicated by relatively little machine vibration.
• Cutting too deep only has negative results. Try to
remove materials in several passes rather than one,
deep pass. Several tests will show the best, most
appropriate cutter impact. Use a forward, backward
and/or circular pattern to achieve your desired
finish.
NOTE: Positioning the machine over the surface in
many directions, as well as dialing the hand wheel up or
down can help create desirable surface patterns. After
several hours of practice, the operator will become
comfortable and should be able to remove materials
faster with enhanced results.
NOTE: The engine should not labor. Run engine at full
speed and adjust forward speed to fit the work being
performed. Harder concrete surfaces will have to be cut
at a slower pace than asphalt or other softer surfaces.
Cutting Drum Assemblies
Different drum configurations can be used for different
applications. Visit
www.graco.com/drumassembly for
instructions on how to assemble various drum
configurations.
Carbide Flail Cutter Assembly
Gradually adjust depth down to remove marking line
(minimal amount of paved surface should be removed).
Carbide Miller Cutter Assembly
Best results for deep cuts are achieved by making
several thin passes. A single pass should be no deeper
than 1/32 in. (0.8 mm) or damage to rods and cutters
could occur.
Diamond Blade Assembly (GrindLazer Pro
Models only)
Diamond Blades are designed to be cooled by airflow
around the blades. Lift blade out of cut every 10 to 15
seconds, then run at full speed for several seconds to
prevent excessive heat build up that could damage the
blades.
NOTE: Each increment on Drum Adjustment Dial (D) is
0.006 in. (0.15 mm) depth change of cutting drum.
NOTICE
Should you desire to tilt the machine, always tilt
forward. Tilting the machine backwards at any time
will flood the spark plug with oil and may cause dam-
age to your engine.
BURN HAZARD
Avoid touching or handling drum after use until it has
completely cooled.
