7.0 PREVENTIVE
MAINTENANCE
7.1
Air Motor Air-Supply Line
7.1.1
Make sure the air supply hose fittings are clean
before connecting the hose to the tool’s air connections.
NOTICE
The filter/regulator in the air supply line protects
the air motor from contamination in the air line.
Take special care to prevent contaminants from
the blasting environment from entering the air
motor or air motor supply hose. Any dust or
abrasive in the air supply that enters the air
motor will cause the air motor to fail. To prevent
contamination, cover the air hose connections
and air motor tubing whenever the air supply or
return hoses are removed. Motor failure from
ingress of dust, abrasive, or any foreign matter
voids the warranty.

Make sure the nozzle washers in the head and
in the extensions are in good condition before screwing
