LUBRICATION

hours of operation, if a lubricator is not used on the compressed
air network, inject 1/2 to 1cm3of approved air tool oil through the

OPERATING FEATURES
GETTING STARTED
Always operate, inspect and maintain this tool in accordance with all regulations (local, state, federal
and country) that may apply to hand-held / hand-operated pneumatic tools.
Be sure all hoses and fittings are the correct size and are tightly secured.
Always use clean, dry air at 90 psig maximum air pressure. Dust, corrosive fumes and/or excessive mois-
ture can ruin the motor of an air tool.
The use of a hose whip is recommended. A coupler connected directly to the air inlet increases tool bulk
and decreases tool maneuverability.
For maximum performance, the coupler on the wall should be the next size larger than the coupler used
on the tool. The coupler closest to the tool should not be less than the proper air supply hose size.
