INSTRUCTIONS FOR EDCO MODEL CD-5 & CD-3 “CHIP-DEK”
SCABBLER
BEFORE STARTING OPERATION:
For effi cient operation of the CD-5 & CD-3, be sure to use a compressor with adequate output. A
compressor output of 150 CFM @ 90 PSI or larger is recommended.
Also, check the level of the lubricator. The proper oil to use is one with a viscosity of 32
centi-strokes (ISO-32). For example, Citgo AW-32 hydraulic oil or Lubriplate HO-32 hydraulic oil.
Tilt machine backwards and check the condition and secureness of the fi ve or three carbide bits.
Use an industrial vacuum to control dust with suffi cient CFM, hook-up the EDCO VAC-500 or
VAC250 Industrial dust control vacuum system, or equivalent, to the three inch vacuum port or
a CD-5 and a VAC-250 or VAC-160 or equivalent on a CD-3.
Determine if the slab is structurally sound and safe. While the CD-5 & CD-3 delivers
a controlled impact and should not damage the base, care should be taken that the
slab is strong enough to withstand the impact of repeated hammering. A slab less than 4 inches
thick may crack under repeated hammering.
OPERATING MACHINE:
Before starting, this machine be sure to read and understand this entire operator’s manual. Hook
air hose (3/4” minimum) from a regulated and fi ltered air supply to the coupler on the handle of the
CD-5 or CD-3 and do not exceed 60 feet of 3/4” hose.
Be sure to us a “whipchek” safety cable at this joint. Failure to do so could result in
serious bodily injury or death. Before supplying the air hose with air, ensure that the
operating valve on the console of the CD-5 or CD-3 is in the “OFF” position.
To start operation of the CD-5 or CD-3, grasp handle bars and turn operating valve to the “ON”
position and pistons will start pounding the pavement. The CD-5 or CD-3 will feel as though the
front head is fl oating. It will be necessary to move the machine so that it will not pound pockets
into the slab. The CD-5 or the CD-3 should be moved slowly in a side to side sweeping motion to
ensure a consistently uniform removal of material. As the machine is operating, it may become
necessary to adjust the hammering action of the CD-5 or CD-3. The addition of an air pressure
regulator between the machine and your compressor will allow for this adjustment. The air
pressure fl owing to the pistons in the cylinder head may be adjusted from 0 PSI, minimum, to 90
PSI, maximum.
