E-CPM-4-8-10-SL8-I-0309
The CPM-4-8-10-ScariLite-8 EDCO concrete Planers were
designed to remove material from the surface of concrete
slabs. The material may consist of excess concrete, coat-
ings, contaminants such as industrial debris, sealer, paint,
production line spill and virtually any foreign substance that
creates a safety or health hazard on walks, passageways
or fl oor surfaces.
The EDCO planers are primarily used for surface preparation
in commercial and industrial buildings. The machine’s total
weight is an advantage when used on upper fl oors where lbs
per sq. feet is an important factor. We have kept the overall
width to less than 36 inches (91 cm) to allow for passage
through most commercial doorways.
Since the maximum depth of cut is 1/2” (2 cm) in increments
of 1/32” to 3/16”, it is not suited for removal of very hard
concrete such as the kind found on roads, bridge decks or
runways. This work is best accomplished by heavy duty
milling machines built for that purpose.
The basic mechanical structure consists of a fabricated steel
frame, a power source - electric, gasoline, or propane (an air
motor can also be adapted), and a rotating drum like cutter
head that can be raised or lowered to a chosen depth by
the operator.
The CPM-4 model is designed with an “up-cut” rotation of
the cutter drum assembly, consequently a milling type action
occurs which is more effi cient than the “down-cut” found on
other manual units. The CPM-8, CPM-10 and ScariLite-8 are
down-cut machines.
The push units require very little manual labor to operate -
the operator controls speed, forward and reverse directions.
Note that it will cut in forward or reverse directions.
The 4” to 10” inch wide drum assemblies consist of a welded
cage holding 4, 6 or 8 hardened shafts - locked in place during
operation and removable when replacing cutters.
Several styles and sizes of cutter are available. All types of
cutters may be used on all sizes of drum assemblies. Cutters
vary in size - 2 3/8” for light removal, 3” diameter for longer
life. Additional cutter wheel specifi cations can be found on
literature and price lists.
The effi ciency of the planer is determined by 3 factors - the
hardness and type of surface to be removed, the type of
What to Expect from your
CPM-4, CPM-8, CPM-10, ScariLite-8 EDCO Concrete Planer
cutting tool and the power behind the cutters.
Since the hardness of the surface cannot be changed
and the cutter type is limited to present state of the art
material and the power source is fi xed - there may be
conditions that are beyond the capability of the planer.
To exceed these limits will only cause problems. Cutter
life will be shortened drastically, excessive vibration will
most likely cause the scarifi er to self destruct.
EDCO cannot accept responsibility if the conditions found
on the job site exceed the ability of the equipment to meet
the contractors expectations. It is the obligation of the
purchaser, user or renter to determine the compatibility
of the planer with the job to be performed.
We at EDCO are prepared to assist the user. We can
provide technical information and comparison data on
jobs of a similar nature. Given information on the project
we can advise the contractor which tools, in our opinion,
will suit the job best, approximate production rates and
possibly arrange a demonstration or suggest an alterna-
tive method or equipment.
EDCO concrete planers, when properly used, will perform
effi ciently and economically, but as with all “demolition”
equipment, unless proper maintenance is provided they
tend to wear out faster than other mechanical devices.
It is important that each job be considered individually.
Testing should be carried out and a determination made
if the project is feasible under the circumstances. In
those instances where no other alternative is available,
various changes in procedure can be tried - shallower
cutting depth, slower forward speeds, spacing of cutters
changed - extra weight added. We do not guarantee
life of cutters, depth of cut, life of equipment (except for
workmanship). Equipment of this type is capable of self
destruction through misuse or abuse and the owner/op-
erator is the vital component that can mean success or
failure of the project.
Our technical information has been obtained from years
of experience on all types of job sites and we will gladly
share this information with you. New materials are con-
stantly being introduced - concrete is made harder with
additives, chemicals and new curing techniques. We try
to keep up with these changes, it’s a never ending job
for us and we need your cooperation to provide us with
accurate job site conditions and information.
