The turbine unit only requires minimal maintenance
●
Ensure its filter (28) element is kept clean at all times.
This is the filter underneath the main body of the turbine. Disconnect the unit from the power supply, turn on side and remove foam material. This
can be washed out if necessary and replaced when dry. From time to time this filter will need replacing (part no.L0058).
●
The turbine bearings are sealed and lubricated for life. There is no maintenance or adjustment required.
●
Clean the turbine and hose unit with a damp cloth after use.
●
The hose is stowed by coiling it between the motor housing and hose cover.
●
The power cord is stowed by wrapping around the base of the unit and locating the plug in the space at the back of the unit.
Gland washers (16) prevent leakage of air passing the needle. This leakage reduces the performance of the spray gun and must, therefore, be kept
to a minimum. After a period of use the gland washers will wear. This is normal and can be compensated by gradual adjustment of the gland nut (15).
Periodically check to ensure the gland nut is not loose. DO NOT OVER-TIGHTEN as this will increase wear of the washers. When necessary just
tighten the nut lightly using the special spanner (27) provided.
By tightening this nut, the inside diameter of gland washers reduce thereby closing any small gap that may have occurred between the needle and
gland washers, therefore, eliminating excessive leakage.
