GASOLINE/PROPANE POWERED EQUIPMENT
• 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 oper ation in an enclosed 100,000 cu. ft. area with only one
change of air per hour is capable of providing deadly con-
centrations of CO in less than fteen minutes. Five changes
of air in the same area will produce noxious fumes in less
than 30 minutes. Gasoline or propane powered equipment
should not be used in enclosed or partially enclosed areas.
Symptoms of CO poisoning include, headache, nausea,
weakness, dizziness, visual problems and loss of consciou ness. If symptoms occur - get into fresh air and seek medical
attention immediately.
ELECTRICAL POWERED EQUIPMENT
Extreme care must be taken when operating electric
models with water present: Ensure power cord is properly 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 motor 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.
• Do not disconnect power by pulling cord. To disconnect, grasp
the plug, not the cord.
• Unplug power cord at the machine when not in use and be
fore servicing.

What to Expect from your
CPU-10FC EDCO Concrete Scarier
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, 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 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 22 1/2” (57 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 machines 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 efcient 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 operation 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 efciency of the scarier is determined by 3 factors - the
hardness and type of surface to be removed, the type of 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 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 alternative method or equipment.
EDCO concrete scariers, when properly used, will
perform efciently 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/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 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.

and the Engine Manufacturer’s Owner’s Manual
before operating this equipment.
Death or serious injury can result if this machine is used improperly.
Safety Guidelines
Eye and ear protection must be worn at all times when this machine is in use. During normal use,
sound levels exceed 92dB. Use only ANSI approved safety glasses to help prevent eye injury. Everyday 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 or caught in moving parts. Steel toe safety shoes should be worn.
• Maintain the machine in safe operating condition with all guards in place and secure, all mechanical fasteners
tight, all controls in working order and the machine congured for the job application. Be sure all safety decals
can be clearly read and understood. Replace damaged or missing decals immediately.
• The CPU-10FC Scarier is designed to plane at, horizontal concrete or asphalt slabs. Scariers maybe equipped
with gasoline, propane or electric motors. They are designed to be operated by a single operator from a position at
the rear of the equipment.
• Keep a safe operating distance to other personnel in the area and never leave the machine running unattended.
• Avoid deck inserts, pipes, columns, openings, electrical outlets, or any objects protruding from slab surface.
• Never operate this machine while under the inuence of drugs, alcohol or when taking medications that impair the
senses or reactions, or when excessively tired or under stress.
• Avoid touching or handling accessories after use, they are hot and can cause burns.
For Electric Models:
Electrical motor must be properly grounded at all times. Check the outlet box to be sure the electrical
service is properly grounded. Be sure adequate power is available. Insufcient power will cause motor to overheat and
burn out.
(amp rating and length). Never use frayed, damaged, taped or underrated extension cords. Electrical shock could
result in death or serious injury to the operator and damage to the equipment.
Carbon monoxide is an invisible, odorless gas that can kill. NEVER REFUEL A HOT ENGINE OR AN ENGINE WHILE
IT IS RUNNING. Only refuel a cool “stopped” engine and in a well-ventilated area. Properly clean any spilled fuel
before starting the engine.
Use only grounded extension cords correctly sized for the current draw and voltage drop
For Gasoline Models:
Poisonous exhaust gas. Do not operate gasoline powered equipment without adequate ventilation.
