Chicago Pneumatic CP785 Series User manual

To reduce risk of injury, everyone using, installing,
repairing, maintaining, changing accessories on, or
working near this tool must read and understand
these instructions before performing any such task.
Air Supply Requirements
1. Supply tool with 90 psig (6.2 bar) of clean, dry air. Higher pressure drastically
reduces tool life.
Lubrication
Use an air line lubricator with SAE #10 oil, adjusted to two drops per minute. If
an air line lubricator cannot be used, add air motor oil to the inlet once a day.
Noise & Vibration Declaration*
2
Vibration value <2.5 m/s , re. ISO 8662-1. (CP785)
2
Vibration value <2.5 m/s , re. ISO 8662-1. (CP785H)
Maintenance
1. Disassemble and inspect air motor every three months if the tool is used every
day. Replace damaged or worn parts.
2. High wear parts are underlined in the parts list.
*These declared values were obtained by laboratory type testing in compliance with the stated
standards and are not adequate for use in risk assessments. Values measured in individual work places
may be higher than the declared values. The actual exposure values and risk of harm experienced by an
individual user are unique and depend upon the way the user works, the workpiece and the workstation
design, as well as upon the exposure time and the physical condition of the user. We, Chicago
Pneumatic, cannot be held liable for the consequences of using the declared values, instead of values
reflecting the actual exposure, in an individual risk assessment in a work place situation over which we
have no control.
2. Connect tool to air line using pipe, hose and fitting sizes shown in the diagram
on page 12.

The goal of Chicago Pneumatic is to produce tools that help you work safely and
efficiently. The most important safety device for this or any tool is YOU. Your
care and good judgment are the best protection against injury. All possible
hazards cannot be covered here, but we have tried to highlight some of the
important ones.
Air Supply And Connection Hazards
!Air under pressure can cause severe injury.
!Always shut off air supply, drain hose of air pressure and disconnect tool
from air supply when not in use, before changing accessories or when
making repairs.
!Never direct air at yourself or anyone else.
!Whipping hoses can cause serious injury. Always check for damaged or
loose hoses and fittings.
!Do not use quick disconnect couplings at tool. See instructions for correct
setup.
!Whenever universal twist couplings are used, lock pins must be installed.
!Do not exceed maximum air pressure of 90 psi/6.2 bar or as stated on tool
nameplate.
Projectile Hazards
!Always wear impact-resistant eye and face protection when involved with
or near the operation, repair or maintenance of the tool or changing
accessories on the tool.
!Be sure all others in the area are wearing impact-resistant eye and face
protection.
!Even small projectiles can injure eyes and cause blindness.
Entanglement Hazards
!Keep away from rotating bit and chuck.
!Do not wear jewelry or loose clothing.
!You can be cut or burned if you come in contact with the drill bit, chips or
work surface.
!Use intermittent drill pressure to avoid long shaved chips.
!Scalping can occur if hair is not kept away from tool and accessories.
!Choking can occur if neckwear is not kept away from tool and accessories.
Bit Binding Hazards
!The drill bit can suddenly bind and cause the work piece or tool to rotate,
causing arm and shoulder injuries.
!Enough torque is generated to cause falls.
!Always use sharp bits.
!Reduce downward pressure at breakthrough.
!ANSI recommends the use of a support handle on drills with a chuck
capacity larger than 3/8 in. or 10 mm.
!Operators and maintenance personnel must be physically able to handle
the bulk, weight and power of this tool.
Workplace Hazards
!Slip/Trip/Fall is a major cause of serious injury or death. Be aware of
excess hoses left on the walking or work surface.
!Maintain a balanced body position and secure footing.
!High sound levels can cause permanent hearing loss. Use hearing
protection as recommended by your employer or OSHA regulation (see 29
CFR part 1910).
!Repetitive work motions, awkward positions and exposure to vibration can
be harmful to hands and arms. If numbness, tingling, pain or whitening of
the skin occurs, stop using tool and consult a physician.
!Avoid inhaling dust or handling debris from the work process which can be
harmful to your health. Use dust extraction and wear respiratory protective
equipment when working with materials which produce airborne particles.
!Proceed with care in unfamiliar surroundings. Hidden hazards may exist,
such as drilling into electric or other utility lines.
!This tool is not intended for use in an explosive atmosphere and is not
insulated for contact with electric power sources.
!Some dust created by power sanding, sawing, grinding, drilling and other
construction activities contains chemicals known to the State of California
to cause cancer and birth defects or other reproductive harm. Some
examples of these chemicals are:
- Lead from lead based paints
- Crystalline silica bricks and cement and other masonry products
- And Arsenic and chromium from chemically-treated rubber
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as dust
masks that are specially designed to filter out microscopic particles.
!For professional use only.
