Compatible compressor and air tool:
GUIDELINES FOR PROPER USAGE AND POERATION
Always ensure the use of appropriately matched air tools and compressors. The compressor should be able to supply a
minimal air delivery of 3.8 SCFM@90PSI to ensure the compressor can run continuously with the RONGPENG Air-Powered
drill. Using tools or a combination of tools that together or separately require air pressure more than that of which the air
compressor can deliver will reduce performance and could void the compressor or tool guarantee/warranty.

AIR SYSTEM
Always use clean, dry, regulated, compressed air at 4 to 7bar (60 to 100PSI).
Do not exceed the maximum and minimum pressure. Operating the tool at the wrong pressure (too low or too high)
will cause excessive noise or rapid wear.
It is recommended that a filter-regulator-lubricator be used and be located as close to the tool as possible.
If a filter-regulator-lubricator is not installed, place up to 6 drops of pneumatic tool oil into the air inlet plug before
each use.
If a filter-regulator-lubricator is installed, keep the air filter clean. A dirty filter will reduce the air pressure to the tool,
which will cause a reduction in power, efficiency, and general performance.
