Declaration of noise and vibration emission
All values are current as of the date of this publication.
These declared values were obtained by laboratory type testing in
accordance with the stated standards and are suitable for comparison
with the declared values of other tools tested in accordance with the
same standards. These declared values are not adequate for use in risk
assessments and values measured in individual work places may be
higher. 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 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 reecting the actual
exposure, in an individual risk assessment in a work place situation over
which we have no control.
This tool may cause hand-arm vibration syndrome if its use is not
adequately managed.
INSTRUCTION MANUAL
Machine Type:
Power tool equipped with 3/8”, 5/8” & M14 spindle with
various grinding wheels for grinding - No other use is
permitted.
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 tting sizes
shown in the diagram below.
3. Do not install a quick coupler directly into the sander
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.
Maintenance
1. Disassemble and inspect tool 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:
Tune-Up Kit:
2050504823 (Incl: 7, 8, 11, 16, 20)
Bevel Gear Kit:
2050504833 (Incl: 13, 22, 24, 27, 29, 30, 31, 32, 34)
