Air Supply; Lubrication And Maintenance - Sunex Tools SX246 Mode D'emploi

Operating Instructions • Warning Information • Parts Break down
fig. 1.

AIR SUPPLY

Tools operate on a wide range of air pressures. It is recommended
that air pressure measures 90 psig at the tool with the trigger fully
depressed and no load applied to the tool. Higher pressure (over 90
psig; 6.2 bar) raises performance beyond the rated capacity of the
tool, which will shorten tool life and could cause injury.
Always use clean, dry air. Dust, corrosive fumes and/or water in the
air line will cause damage to the tool. Drain the water from air lines
and compressor prior to running tool. Clean the air inlet filter screen
weekly. The recommended hookup procedure can be viewed in FIG. 1.
The air inlet used for connecting air supply has standard 1/4" NPT.
Line pressure should be increased to compensate for unusually long
air hoses (over 25 feet). Minimum hose diameter should be 3/8" I.D.
and fittings should have the same inside dimensions and be tightly
secured.
Ensure an accessible emergency shut off valve has been installed
in the air supply line and make others aware of its location.
TROUBLESHOOTING
Other factors outside the tool may cause loss of power or erratic
action. Reduced compressor output, excessive drain on the air line,
moisture or restrictions in air pipes or the use of hose connections
of improper size or poor conditions may reduce air supply. Grit or
gum deposits in the tool may cut power and may be corrected by
cleaning the air strainer and flushing out the tool with gum solvent
oil or an equal mixture of SAE #10 and kerosene. If outside conditions
are in order, disconnect tool from hose and take tool to your nearest
authorized service center.

LUBRICATION AND MAINTENANCE

Lubricate the air motor daily with high quality air tool oil. If no air line
oiler is used, run 1/2 oz. of oil through the tool. The oil can be squirted
into the tool air inlet or into the hose at the nearest connection to
the air supply, then run the tool. A rust inhibitive oil is acceptable for
air tools.
WARNING: After an air tool has been lubricated, oil will discharge
through the exhaust port during the first few seconds of operation.
The exhaust port must be covered with a towel before applying air
pressure to prevent serious injury.

OPERATION
Always turn off the air supply, drain hose of air pressure and
detach tool from air supply before installing, removing or adjusting
any part or accessory on this tool, or before performing any
maintenance on this tool.
Needle Scalers are used for removal of rust, old paint, concrete
and slag from new welds on many uneven metal surfaces. Needles
adapt themselves to flat, curved and uneven surfaces. Excessive
speed reduction indicates too much force being applied to the work
surface. Apply moderate hand pressure to the tool and allow the tools
accessories to do the work.
NOTE: During operation, safety goggles should always be worn to
guard against flying debris (users and bystanders).
