Maintenance
Daily
The System HVLP Turbine Sprayers are lifetime
lubricated. The only maintenance required is filter
cleaning and replacement.
The turbine filter must be clean at all times to provide
sufficient air flow to cool motor and atomize the fluid.
Check turbine pre-filter (22) daily for cleanliness.
Check the main paper filter (21) weekly, minimum.
Clean as necessary.
NOTE: To check filter, turn on turbine and place piece
of paper against pre-filter. If air intake holds paper in
place, filter is okay.
System 3800
and System 4900
models have an
air filter indicator light on the front panel. If the filter is
good the light is out. If the filter is clogged or has low
airflow the light will come on as in Fig. 7 below.

To clean filter:
1.
Turn off and unplug turbine.
2.
Loosen four thumbscrews (16), and remove filter
retainer (15) and pre-filter (22). See Fig. 8.
3.
Remove main filter (21) and clean by using one of
the following three methods:
Tap filter gently on flat surface, dirty side
down.
CAUTION
To prevent damage to filter, do not use compressed
air on a wet filter.
Direct compressed air (100 psi [7 bar, 70 kPa]
maximum) through filter panel in opposite
direction of arrows on side of filter (from the
clean side to the dirty side).
Soak filter for 15 minutes in water and mild
detergent. Rinse filter until clean. Air dry. Do
not use compressed air on damp or wet filter.
WARNING
To avoid damage to the turbine and possible elec-
tric shock, never install a damp filter in the turbine.
CAUTION
To keep out dirt, do not operate the turbine sprayer
without both filters installed.
