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.
2. Connect tool to air line using pipe, hose and fitting sizes shown in the diagram
on page 12.
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.
Die Adjustment
Loosen clamp nut (9), rotate die (8) aligning slot with pin (4) at desired position.
Tighten clamp nut before operating tool.
Noise & Vibration Declaration*
2
Vibration value < 2.5 m/s , re. ISO 8662-1.
Maintenance
1. Disassemble and inspect parts 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.
Punch Replacement
Remove clamp nut (9) and die (8). Loosen set screw (6) and remove punch.
Reverse procedure to install new punch.
*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.
Sound pressure level 93.0 dB(A) in accordance with Pneurop 8N-1. For sound
power, add 10 dB(A).

Signature of Issuer
!Avoid direct contact with accessory and work surface during and after
work.
!Cutting edges and saw blades can become hot during use. Do not
touch.
!Never force the tool to cut faster or through heavier gauge material than
rated capacity.
!To prevent damage to the tool and accessory, accessory must be held
firmly against work surface while cutting.
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.
!Proceed with care in unfamiliar surroundings. Be aware of potential
hazards created by your work activity.
!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.
