▪ Do not wear loose fitting clothing and jewelry which may become caught in moving
parts and result in serious injury.
▪ Do not depress trigger when connecting the air hose.
▪ Never trigger the tool when not applied to a work object. Accessories must be
securely attached.
▪ Make sure all connections are secure and check air hoses for weak or worn condition
before each use.
▪ WARNING! Disconnect air supply before installing or any maintenance.
5 AIR SUPPLY
▪ The air supply MUST be greater than air requirement of the tool. Recommended air
compressor is 3/4HP.
▪ Air Hose: Using 3M or7.5M long with 5mm I.D. and 1/4"PT threads is recommended.
However, hoses longer than 7.5M should use 10mm even 12 mm I.D. For proper
performance and more convenience. Using fittings or air hoses which are too small
can create a pressure drop and reduce the power of the die grinder.
WARNING! Keep hoses away from heat, oil and sharp edges. Replace any
hose that is damaged, weak or worn. The use of air filters and air line
lubricators is recommended.
6 LUBRICATION
An automatic in-line filter-regulator-lubricator is recommended (Fig 1) as it increases tool life
and keeps the tool in sustained operation. 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.
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.
▪ It is most important that the tool be properly lubricated by keeping the air line
lubricator filled and correctly adjusted. Without proper lubrication the tool will not work
properly and parts will wear prematurely.
▪ Use the proper lubricant in the air line lubricator. The lubricator should be of low air
flow or changing air flow type, and should be kept filled to the correct level. Use only
recommended lubricants, specially made for pneumatic applications. Substitutes may
harm the rubber compounds in the tools, O-rings and other rubber parts.
7 IMPORTANT!!!
If no filter/ pressure regulator/ lubricator is installed in the compressed air system, then
pneumatic tools must be lubricated with 2 to 6 drops of oil at least once a day or after every
two hours of use. This must be done directly along the male coupler or the screw (OIL)
provided for the purpose on the side of the tool’s housing.
