!
Never use a grinding wheel marked with a speed lower than the air grinder
speed.
Grinding Wheel Mounting Hazards
!
Correct grinding wheel mounting is necessary to prevent injury from broken
wheels.
!
Do not use chipped or cracked grinding wheels.
!
Grinding wheels should be a free fit on the spindle to prevent stress at the
hole.
!
Use only wheel collars that come with the grinder for mounting the grinding
wheel.
!
Flat washers or other adapters may over stress the wheel. Always use heavy
paper blotter discs between the wheel collars and the grinding wheel.
!
Tighten the wheel on the spindle to prevent spin off when the air grinder is
turned off.
!
Before grinding, test grinding wheel by briefly running tool at full throttle. Be
sure to use a barrier (such as under a heavy work table) to stop any possible
broken wheel parts.
Workplace Hazards
!
Slip/Trip/Fall is a major cause of serious injury or death. Be aware of excess
hose left on the walking or work surface.
!
High sound levels can cause permanent hearing loss. Use hearing protection
as recommended by your employer or OSHA regulation (see 29 CFR part
1910).
!
Maintain a balanced body position and secure footing.
!
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.
!
Operators and maintenance personnel must be physically able to handle the
bulk, weight and power of this tool.
!
This tool is not intended for use in explosive atmospheres 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.

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.
Wheel Guard Usage
!
Always use the recommended wheel guard to prevent injury from broken
grinding wheel parts.
!
If a guard has withstood a wheel breakage do not continue to use it. It may
be damaged.
!
Position the guard between the grinding wheel and the operator.
!
Use barriers to protect others from wheel fragments and grinding sparks.
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.
!
A grinding wheel that bursts can cause very serious injury.
!
Daily measure the air grinder speed with a tachometer to make sure it is not
greater than the RPM marked on the grinding wheel.
Air Supply Requirements
1. Supply tool with 90 psig (6.2 bar) of clean, dry air. Higher pressure drastically
reduces tool life.
2. Connect tool to air line using pipe, hose and fitting sizes shown in the diagram
on page 12.
3. Do not install a quick coupler directly into the grinder throttle handle.
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*
Sound pressure level 85 dB(A), re. Pneurop 8N-1.
2
Vibration value < 2.5 m/s , re. ISO 8662-1.
Maintenance
1. Disassemble and inspect air motor and governor assembly 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.
3. To keep downtime to a minimum, the following service kit, detailed on page 12,
is recommended: C138089 Tune-Up Kit
*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.
For sound power, add 10
dB(A).
