9. Avoid using an unnecessarily long air hose. Choose a hose that is appropriate for the situation, as a hose
that is too long and running across the floor can be more dangerous than helpful.
10. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections
are secure.
11. Always carry a tool by its handle, never carry the tool by the air hose.
12. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The hose
diameter should be 3/8 in. l.D.
13. Air tool CFM consumption ratings are based upon a 25% duty cycle. If you require continuous duty, a larger
compressor will be required (eg. 4.0 CFM tool at continuous duty requires 16.0 CFM to function at
maximum torque).
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. Use two drops of air
tool oil to lubricate the tool and run the tool under no load until exhaust is clear.
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.
VIBRATION PRECAUTIONS
This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and shoulders.
1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and
then have regular medical check ups to ensure medical problems are not being caused by or worsened from
tool use. Pregnant women or people who have impaired blood circulation to the hands, past hand injuries,
nervous system disorders, diabetes or Raynaud's Disease should not use this tool. If you feel any medical
symptoms related to vibrations (such as tingling, numbness, and white or blue fingers), seek medical
attention as soon as possible.
2. Do not smoke during use. Nicotine reduces the blood flow to the hands and fingers, increasing the risk of
vibration-related injury.
3. Wear suitable gloves to reduce the vibration effects on the user.
4. Use tools with the lowest amount of vibration when there is a choice between different processes.
5. Do not use for extended periods. Take frequent breaks when using this tool.
