Additional Information:
• Since cutter wheels wear, the cutting depth will change. Compensate for wear by adjusting the depth control.
To reach greater depth in the concrete it is best to make several passes at increments of 1/8” to 3/16” per pass.
Never use a fi ne spaced cutter head to cut deeper than 1/8”. All deep cuts should be started from a stationary
position. When the cutting depth is reached the plane should then move forward.
• The cutter wheels have an oversized arbor hole (1/4” larger diameter then the shaft diameter on which it is mount-
ed). This “play” is needed to absorb some of the shock of the cutter contacting the concrete. 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.
• For general use, EDCO recommends the use of tungsten carbide cutter wheels (CP-408-TV).
Concrete:
• 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 hard surface. Material removal depth should not exceed 1/8” per pass thus
may require several passes to reach the desired depth of cut.
Asphalt:
• When cutting asphalt, depths of 1/4” per pass can be reached using a medium set up. Let the job requirements
guide your selection of cutter spacing. Deep cuts require wide cutter spacing. Asphalt will usually break out
between cutters and a fairly uniform clean cut is the result. Specifi c information on asphalt cutting is available
from EDCO upon request.
Thermoplastic Lines:
• The EDCO CPU-12 model is ideally suited to remove thermoplastic lines - the upcut feature removes the plastic
from the surface by “milling” or lifting. In excessively hot weather it may be necessary to sweep the plastic away
from in front of the planer. Hot plastic can build up on the wheels changing the cutting depth setting. To keep
the thermo plastic from heating up, we recommend that whenever possible water be sprayed on the work sur-
face.
CP-405 cutter wheels have a maximum depth
of 3/4” when new (hi-carbon).
CP-404 cutter wheels have a maximum depth
of 1/2” when new (hi-carbon)
