INSTRUCTION MANUAL
Air Supply Requirements
1. Supply tool with 90 psig (6.3 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 below.
3. Do not install a quick coupler directly into the grinder
throttle handle.
4. Minimum compressor requirement: 3hp (2238 w), 60 gal.
air tank.
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.
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.
3. To keep downtime to a minimum, the following service kits
are recommended:

re. ISO 8662-13.
For making estimates of daily vibration exposures, useful
information may be found in CEN/TR 15350: 2006,
“Mechanical vibration - Guideline for the assessment of
exposure to hand-transmitted vibration using available
information including that provided by manufacturers of
machinery”
*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.
