Use with Pneumatic Nailers:
Do not exceed the maximum recommended pressure (PSI) for your pneumatic nailer.
Air hoses may cause up to 15 PSI drop in pressure, so you may need to set the
compressor and/or regulator to a higher output to maintain the required pressure
at the tool.
The airflow (CFM) required to power multiple nailers simultaneously is dependent
on the number of nailers and the rate at which they are being used. For example,
a smaller portable compressor rated at 3 - 4 CFM may be able to sufficiently operate
up to three nailers that are only being used occasionally. However, a much larger
compressor with a CFM rating of 14 or higher may be required to simultaneously
operate four nailers being used steadily at rapid production rates.
Consult the owner's manuals included with your pneumatic nailers for specific
details on airflow and air pressure requirements.

OPERATING INSTRUCTIONS
CARE AND MAINTENANCE
1. Always operate the product with care by following all the warnings and instructions
in this manual.
2. Always place the product on a flat surface or have it fixed safe and secure to a
stable place for operation.
3. Always disconnect air connection hose and air supply when the product is
not in use.
4. Inspect the product periodically and, if damaged, have it repaired by an authorized
technician. When servicing, use only identical replacement parts. Use of any other
parts will void the warranty. Only use accessories intended for use with this
product. For your safety, maintenance should be performed regularly by a qualified
technician.
5. When you are not using the product for a long time, disconnect it from air hoses,
wipe it clean with a dry cloth and store it in a dry and safe place out of reach
of children.

Use with Other Pneumatic Tools:
Other pneumatic tools such as impact wrenches, grinders, sanders and spray guns
typically have much higher airflow requirements than pneumatic nailers due to their
longer operating cycles and run times.
Air hoses may cause up to 15 PSI drop in pressure, so you may need to set the
compressor and/or regulator to a higher output to maintain the required pressure at
the tool.
The airflow (CFM) required to power multiple pneumatic tools simultaneously is
dependent on the number of tools connected and the rate at which they are being
used. For example, a compressor rated at 8 - 12 CFM may be able to sufficiently
operate two pneumatic tools that are only being used occasionally. However, a much
larger compressor with a CFM rating of 20 or higher may be required to
simultaneously operate two or more pneumatic tools being used frequently or
continuously.
Consult the owner's manuals included with your pneumatic tools for specific details
on airflow and air pressure requirements.
