Cutting Heads / Drums:
• Drum assembly revolves at approximately 2000 R. P. M.; Model CPU-10FC is an “up-cut” planer. Depth of cut
is completely determined by the material to be cut, horsepower of the engine and spacing of the cutter wheels on
the cutter head.
• All cuts should be started from a stationary position - when the cutting depth is reached the plane should then
move forward.
• The engine should not labor. Run at full throttle and adjust forward speed to fit the work being performed. Very
hard concrete will have to be cut at a slower pace then asphalt or deteriorated surfaces.
•
If it is necessary to make deep cuts - make several shallow cuts to achieve the desired depth. If the cutting depth
is set too deep the cutter wheels will not be able to absorb the shock and damage to the equipment will result.
•
The cutter wheels have an oversized arbor hole. This “play” is needed to absorb some of the shock of the cutter
contacting the concrete.
•
Cutting speed is directly proportional to the amount of material to be removed in one pass; an example - cutters
spaced on 1” centers will penetrate to a greater depth than those spaced at 1/2” centers, and the planer will move
forward faster. Most of the material in the path of the cutting head will be removed either by the cutters them-
selves or through the natural hammering action and spalling of the material being cut. A later pass with cutters
spaced closer together will remove the ridges.
To Reach Maximum Depth in Concrete:
•
It is best to make several passes - increments of 1/8” or even less if surface is extremely hard.
•
Use coarse (wide spacing) for initial passes. Complete job with medium spacing. Never use a fine spaced cutter
head to cut deeper than 1/8”.
•
Some concrete slabs, especially if they are covered with water a good deal of time or if they have been treated
with hardeners, develop an extremely high surface strength.
•
Material removal depth should not exceed 1/8” per pass thus requiring several passes to reach the desired depth
of cut.
To Cut Asphalt:
•
This surface is usually easy to penetrate - depths of 1/4” can be reached using medium spacing. Let the job
guide your selection of cutter spacing. Deep cuts require wide cutter spacing. Asphalt will usually break out be-
tween cutters and a fairly uniform clean cut is the result.
Note: Specific information on asphalt cutting is available upon request.
Fine Cutting:
•
This assembly should be used for very shallow or cleaning operations. Check with dealer for special cutter
wheels for removal of paint build-up or similar surface coatings.
