This product is designed for installing and removing
threaded fasteners in wood, metal and plastic. No
other use permitted. For professional use only.
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.

3/8" (10mm)
Lubrication
1. Use an air line lubricator with SAE #10 oil,
adjusted to two (2) drops per minute. If an air line
lubricator cannot be used, add air motor oil to the
inlet once a day.
2. Monthly, lubricate the drive bushing and ratchet
yoke with a good grade bearing grease.
Periodically, depending upon use, the ratchet
head assembly should be removed, cleaned and
re-greased.
Maintenance
1. Tool should be oiled on a daily basis for best
performance. Every 3 to 6 months the tool's head
should be greased using approved CP Gear
Grease. If the tool loses performance over time,
tool should be sent to a CP Certified Service
Center to be checked and repaired as needed.
2. High wear parts are underlined in the parts list.

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.
