READ AND UNDERSTAND THE OPERATORS INSTRUCTION MANUAL THOROUGHLY
BEFORE ATTEMPTING TO OPERATE THIS EQUIPMENT.
Death or serious injury could occur if this machine is used improperly.
Extreme care must be taken when operating electric
models with water present: Ensure power cord is prop-
erly grounded, is attached to a Ground-Fault-Interrupter
(GFI) outlet, and is undamaged.
• Check all electrical cables - be sure connections are tight and
cable is continuous and in good condition. Be sure cable is
correctly rated for both the operating current and voltage of
this equipment.
• Improper connection of the equipment-grounding conductor can
result in a risk of electric shock. Check with qualied electri-
cian or service person if there is any doubt as to whether the
outlet is properly grounded. Adhere to all local codes and
ordinances.
• NOTE: In the event of a malfunction or breakdown, grounding
provides a path of least resistance for the electric current to
dissipate. The machine is equipped with a grounded plug
and must be connected to an outlet that is properly installed
and properly grounded. DO NOT modify the plug provided on
the motor. If the plug does not t the outlet have a qualied
electrician install the proper receptacle.
• Switch motor OFF before disconnecting power.
• Engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproduc-
tive harm.
• Gasoline is extremely ammable and poisonous. It
should only be dispensed in well ventilated areas,
and with a cool engine.
• Small gasoline engines produce high concentrations of car-
bon monoxide (CO) example: a 5 HP 4 cycle engine opera-
tion in an enclosed 100,000 cu. ft. area with only one change
of air per hour is capable of providing deadly concentrations
of CO in less than fteen minutes. Five changes of air in the
same area will produce noxious fumes in less than 30 min-
utes. Gasoline or propane powered equipment should not be
used in enclosed or partially enclosed areas. Symptoms of
CO poisoning include, headache, nausea, weakness, dizzi-
ness, visual problems and loss of consciousness. If symp-
toms occur - get into fresh air and seek medical attention
immediately.

The CPU-10FC EDCO concrete scarier was designed to
remove material from the surface of concrete slabs. The
material may consist of excess concrete, coatings, contami-
nants 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 oor surfaces.
The EDCO scariers are primarily used for surface prepara-
tion in commercial and industrial buildings. The machine’s
total weight is an advantage when used on upper oors
where lbs per sq. feet is an important factor. We have kept
the overall width to 24” (61 cm), with outrigger 30” (76.2cm)
to allow for passage through most commercial doorways.
Since the maximum depth of cut is 1/2” (2 cm) in increments of
1/8” 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 ma-
chines built for that purpose.
The basic mechanical structure consists of a fabricated steel
frame, a power source - electric or gasoline and a rotating
drum like cutter head that can be raised or lowered to a
chosen depth by the operator.
The CPU-10FC model is designed with an “up-cut” rotation of
the cutter drum assembly, consequently a milling type action
occurs which is more ecient than the “down-cut” found on
the manual units.
The self propelled units require very little manual labor to
operate - a single lever controls speed, forward and reverse
directions. Note that it will cut in forward or reverse directions.
The 10 inch wide drum assembly consists of a welded cage
holding 4 or 6 hardened shafts - locked in place during op-
eration and removable when replacing cutters.
Several styles and sizes of cutter are available. All types
of cutters may be used on both sizes of drum assemblies.
Cutters vary in size - 2 3/8” for light removal, 3” diameter
for longer life. Additional cutter wheel specications can be
found on literature and price lists.
The eciency of the scarier is determined by 3 factors - the
hardness and type of surface to be removed, the type of cut-
ting tool and the power behind the cutters.
What to Expect from your
CP-C C Concrete Scarier
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 xed - there may be
conditions that are beyond the capability of the scarier.
To exceed these limits will only cause problems. Cutter
life will be shortened drastically, excessive vibration will
most likely cause the scarier 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 scarier 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 scariers, when properly used, will
perform eciently and economically, but as with all
“demolition” equipment, unless proper maintenance is
provided they tend to wear out faster than other mechani-
cal 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/
operator 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 gladly share
this information with you. New materials are constantly
being introduced - concrete is made harder with addi-
tives, 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 ac-
curate job site conditions and information.

Safety Guidelines
Read and understand this Operator’s Instruction Manual,
and the Engine Manufacturer’s Owner’s Manual
before operating this equipment.
Death of serious injury can result if this machine is used improperly.
Eye and ear protection must be worn at all times while the saw is in use. During normal operation,
sound pressure levels exceed 85dBA. Use only ANSI approved safety glasses to help prevent eye
injury. Standard eyeglasses have only impact resistant lenses; they are NOT safety glasses.
Operator must wear appropriate clothing and footwear. Do not wear loose clothing or jewelry that
can get tangled in moving parts. Footwear should provide sure footing and protection from debris that
may be dropped. Take steps to insure hair will not be caught in moving parts. If necessary, tie it back.
• When loading or unloading the saw, use caution. Make sure rolling table is locked so that the blade will not be
damaged. Do not move the saw while the engine is running.
• Never exceed the maximum operating speed of the blade. Match the blade speed rating with the arbor shaft speed.
(See page 11)
• Never leave the saw running unattended.
• Never operate this saw under the inuence of drugs, alcohol or when taking medications that impair the senses or
reactions, or when excessively tired or under stress.
• Do not lend or rent this equipment without including the Operator’s Instruction Manual and the Engine Manufacturer’s
Manual.
• Make sure all safety decals can be clearly read and understood. Replace damaged or missing decals immediately.
For Electric Models:
• Electric motor must be properly grounded at all times. Check the outlet box to be sure the electrical service is
properly grounded and that adequate power is available. Insucient power will cause motor to overheat and burn out.
Use only grounded extension cords correctly sized for the current draw and voltage drop (amp rating and length).
Never use frayed, damaged, taped or underrated extension cords. Electrical shock could result in death or serious
injury and damage to the equipment.
For Gasoline Models:
• Poisonous exhaust gas. Do not operate gasoline powered equipment without adequate ventilation. Carbon monox-
ide is an invisible, odorless gas that can kill. NEVER REFUEL AN ENGINE WHILE IT IS HOT OR AN ENGINE
WHILE IT IS RUNNING. Only refuel in a well-ventilated area and only refuel after the engine has cooled completely.
Thoroughly cleanup any spilled fuel before starting the engine.
Dry cutting creates a large volume of airborne dust. For health reasons, the operator should wear an ap-
plicable respirator. The dust may contain chemicals known to cause serious illnesses, including Silicosis
- a fatal disease of the lungs. Check the chemical properties of the material to be cut and follow all EPA/
OSHA regulations.
Safety warnings and guidelines do not by themselves eliminate danger.
They are not substitutes for proper accident prevention procedures and good judgement.

Operating Instructions
Before Starting the Machine:
• Perform a visual inspection of the entire machine and all daily maintenance according to the Maintenance
Schedule on page 15.
• Locate and be familiar with all engine/motor and operating controls (Figures 2).
• For Gasoline models, obtain the Engine Manufacturer’s Owner’s Manual. Read it and understand it before con-
tinuing. Follow the engine manual for break-in instructions.
• Use the correct cutters for the job. Be sure cutter drum is balanced, the number, size and type of cutter wheels
are correct and the cutter drum shaft is locked and secured.
• Be sure all fasteners are tight and secure, check for signs of metal cracking or fatigue, inspect for damage to
electrical wiring, damage to fuel lines, check bearings, etc.
• Be sure all guards are in place. Do not operate unless cutter drum guard is in place and secure.
• Inspect work area to determine the presence and location of deck inserts, pipes, columns and objects protrud-
ing from the slab surface so that they may be avoided during operation.
• Adjust the handles for operator comfort and safe operation. Be sure to retighten knobs. (Figure 2, Item 9)
• Raise the cutter head to the full “up” position using the cutter head lever on the console. (Figure 2, item 1)
• Move the machine into operating position by disengaging the clutch (Figure 2, item 2). Lower clutch lever when
unit is in position.
DO NOT disengage clutch when engine is running and cutter drum is in contact with slab surfaces.
Failure to comply could result in serious bodily injury and/or damage to the equipment.
Starting the Engine/Motor:
For Electric Models:
• Be sure the “OFF” button is depressed on the motor starter box.
• Hook up the correct voltage/phase electrical power source by plugging into the connector provided. If the cord
does not mate with the connector, consult a qualied licensed electrician before continuing.
• Verify that the electrical current being supplied is the proper voltage and phase required to run the equipment
• Check motor rotation. Cutter drum rotation on the model CPU-10FC is “upcut.” DO NOT use if drum rotation is
incorrect - have a qualied electrician make the necessary change in the main control panel or motor connection box.
For Gasoline Models:
• Consult the Engine Manufacturer’s Owner’s Manual and follow the directions for starting the engine and allow the
engine to warm up.

Operating Instructions
Starting the Cut:
• Crank Depth Control up.
• Slowly lower the cutter head to the slab surface with the cutter head lever. (Figure 2, Item 1)
• Lift the knob of the Depth Control to unlock and turn the hand wheel slowly until the cutter head contacts the slab
(you will hear the sound of the cutter wheels contacting the slab). Continue adjusting the depth of cut until the
desired depth is reached; max depth of cut 3/8” (9.5 mm).
• Use an Industrial Vacuum Dust Control System for dry planing operations.
Forward/Reverse Ground Speed Control:
• The drive control lever (Figure 2, Item 8) provides variable ground speed in both forward or reverse directions.
The lever is spring loaded and returns to neutral when released. Ground speed is increased by moving the lever
forward away from the neutral position. Depth of cut and hardness of material will determine the most ecient cutting
speed. Deep cutting requires slower forward speeds, allow engine to run at full RPM during the cutting operation.
To Stop Cutting:
• Move drive control lever to neutral, raise cutter head assembly above slab surface.
• For gasoline models, close throttle and turn the ignition switch to the “o” position.
• For electric models, depress the “OFF” button.
After Cutting:
• At the end of the day, clean the entire machine after it has cooled. Check for worn or damaged cutters and per-
form any required maintenance. See Maintenance Schedule and Instructions on page 13.
Transporting:
• Before hoisting, always inspect frame and attachment hardware for damage. Use proper and
safe hoisting techniques and approved hardware. CPU-10FC weight is approximately 530 lbs (240 kg).
Never hoist a machine over top of where people are working or standing. Never hoist a machine while the engine is
running. Serious person injury or damage to the equipment can result.

Operating Instructions
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 t 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 ne 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: Specic 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.

rac ine eoal
• For this operation, be sure to set depth of cut to just penetrate the paint. Most state and municipal agencies
require 70% to 80% removal. If the road surface was pitted (worn or just old and full or uneven areas when it
was painted), it will be impossible to remove the paint from the depressions without changing the depth setting.
• We suggest leaving these areas to be completed last after the majority of the lines have been removed. Return
to the problem spots , reset the depth and proceed to remove the paint. This procedure will minimize the time
necessary to do the job and will prevent cutting into the road surface.
• The EDCO CPU-10FC model is ideally suited to remove thermoplastic lines - the upcut feature removes the plas-
tic 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 tends to build up on the tires changing the cutting depth setting.
• To keep thermoplastic from heating up, we recommend to spray water on the work surface whenever possible.
Note: If the CPU-10FC will be used for trac line removal, the optional front outrigger wheel assembly will follow the
contour of the surface to be cut. By doing this you can control the amount of surface to be removed with little or no
damage beneath the paint.
Refer to the CPU-10FC Assembly Instructions booklet
for suggested Cutter Drum setups.
Cutter Wheels
Use only EDCO approved cutter wheels. Cutter wheels for all application are available - sizes and types
vary. Complete information is available from EDCO.
CP-403: Hardened steel spacers for use
with all cutter wheel set ups.
CP-404: 2-3/8” diameter -1” ID x 3/16”
max.depth of cut - 1/2” - hi-carbon cutters -
use on concrete 3500 PSI or less.
CP-404P: Same as above, except teeth
are pointed to aid in removal of paint or
similar surface material - points wear and
become at. When this happens, use as
you would standard CP-404.
CP-405: 3” diameter - 1” ID x 3/16” - max.
depth 3/4” - hi-carbon steel cutters - use on
concrete 3500 PSI or less.
CP-405P: Same as above, except teeth

Outrigger Wheel Assembly: (Optional)
Outrigger wheel assembly (Figure 5) is designed to al-
low the drum to follow the contour of the slab. Wheels
are aligned with cutting drum to follow highs and lows
of the slab removing a consistent depth over the entire
surface. Can be used with all accessories but highly
recommended for diamonds and heavy duty roto peen,
removing trac lines or thin coatings.
Do Not Bottom Cutter Assembly
If front wheels are not in contact with slab surface when
planing you are bottoming the cutter head. You are riding
on the drum & cutter wheels. Cutter wheels will wear
uneven or break if this is continued. (Figure 6)
Re-adjust depth - turn ne adjustment in “up” direction
until cutters are free and cutting is being accomplished
by “hammering” action only.
Failure to follow these instructions will cause undue cut-
ter wear, breakage, bearing failure or excessive vibration
that will be transmitted back to the machine frame and
engine eventually causing a virtual self-destruction of
the unit.

Important!
• Check oil level before operation. Change engine oil and lter according to engine manufacturers recommendations.
• Clean air lter element daily.
Belts:
• On new equipment, and after replacing a set of belts, they should be re-tensioned after the rst four hours of use.
• New belts will be sti and will loosen with use. Proper belt tension must be maintained to transmit the engine
power to the cutting drum. Slipping belts will overheat, the blade life will be shortened and the cutting speed lim-
ited. Over tensioned belts will shorten the belt and bearing life.
• Damaged, stretched or excessively worn belts should be replaced with a new matched set.
• To tension belts, loosen motor mounting hardware slightly. Use the jacking bolt to adjust the motor until the belts
are tight. Re-torque the engine mounting hardware.

Drum Bearing Replacement
Important!
1. Remove hood and belt cover.
2. Remove spindle shaft. Remove 2 left hand nuts on left side of shaft. Note: These nuts loosen to the right. Set aside.
Remove shaft. If the debris has hardened on shaft you might need to tap out with a hammer and drift pin. Remove
drum and set aside.
3. Remove 4 - 3/8th - 24 x 1 1/2 HH bolts, washers, and lock nuts from each bearing and set aside. Check to see if
bearings have factory installation shims. If so, note the placement.
4. Install new bearings placing the factory shims in there original position. Note: Make sure to reinstall the dust shields
with the new bearings.
5. When assembly is complete slide the shaft through both bearings. If it doesn’t slide through smoothly repeat steps 3
and 4 until it does. This is required. If the shaft doesn’t pass through both bearings easily it will put excessive side-
load on the bearings and cause premature failure.

DUST AND CRYSTALLINE SILICA WARNING
Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust,
mists and fumes containing chemicals known to cause serious or fatal injury or illness, such as
respiratory disease, cancer, birth defects or other reproductive harm. If you are unfamiliar with
the risks associated with the particular process and/or material being cut or the composition of
the tool being used, review the material safety data sheets and/or consult your employer, the
manufacturers/suppliers, governmental agencies such as OSHA and NIOSH and other sources
on hazardous materials. California and some other authorities, for instance, have published lists
of substances known to cause cancer, reproductive toxicity, or other harmful eects.
Control dust, mist and fumes at the source where possible. In this regard use good work practices
and follow the recommendations of the manufacturers/suppliers, OSHA/NIOSH, and occupa-
tional and trade associations. Water should be used for dust suppression when wet grinding/
cutting/drilling is feasible. When the hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should always wear a respirator approved by
NIOSH/MSHA for the material being used.
Grinding/cutting/drilling of masonry, concrete and other materials with silica in their composi-
tion may give o dust or mists containing crystalline silica. Silica is a basic component of sand,
quartz, brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial
inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other authorities have listed respirable crystalline silica
as a substance known to cause cancer. When grinding/cutting/drilling such materials, always
follow the respiratory precautions mentioned above.
