DISCONNECTING AIR SOURCE
WARNING! Failure to follow these steps could result in severe injury, tool or property damage.
Disconnect the butterfly air impact wrench from the air source before cleaning, servicing, changing parts /
accessories or when not in use.
1. Turn the air regulator to the OFF or L position.
2. Turn off the air compressor.
3. Disconnect the air pressure hose.
4. Discharge any residual pressure inside the butterfly air impact wrench.
LUBRICATION
1. It is very important that the tool be properly lubricated. Without proper lubrication, the tool will
not work properly and parts will wear prematurely. Manually dropping a drop or two of air tool
oil once a day into the tool’s male connector is better than using an automatic in-line lubricator,
which should only be required when there are multiple users of the same tool.
2. Keep the air line lubricator filled and correctly adjusted. The in-line lubricator should be
regularly checked and filled with air tool oil. Proper adjustment of the in-line lubricator is
performed by placing a sheet of paper next to the exhaust ports and holding the throttle open
approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the
paper. Excessive amounts of oil should be avoided.
3. Air tool oil is the only recommended lubricant for use in all air tools. Do not try to use other
types of lubricants to oil your tools. Using the wrong lubricant will cause premature tool
failure and / or loss of power. Use only recommended lubricants, specially made for pneumatic
applications. Substitutes may harm the rubber compounds in the tool’s O-rings and other
rubber parts.
4. Oiling your air tool regularly is important, but it is also important not to over oil your air tool.
Over oiling can cause premature tool failure. Your tool may not be ruined, but it will begin to
experience loss of power that will continually get worse until it no longer works. The tool then
has to be taken apart and cleaned of excess oil.
5. All air tools are packed in grease to prevent corrosion of internal parts during shipping and
storage. We recommend you clean this out to have optimum performance from your new air
tool. Add a generous amount of air tool oil in the air inlet, and then run the tool under no load
until exhaust is clear to remove packing grease. To maintain, add only one or two drops daily or
every 6 to 8 hours of use.
6. In the event that it becomes necessary to store the tool for an extended period of time
(overnight, weekend, etc.), it should receive a generous amount of lubrication at that time.
The tool should be run for approximately 30 seconds to ensure oil has been evenly distributed
throughout the tool. The tool should be stored in a clean and dry environment.
WARNING! Never use penetrating oil to clean or lubricate your air tool. Penetrating oils are a solvent
that will break down the internal grease and cause the air tool to seize up.
