Maintenance
Daily
The turbine systems are lifetime lubricated. The only
maintenance required is filter cleaning and replace-
ment.
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 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.
The HVLP 3800 and 4900 ProCompt sprayers 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. 6 below.

To clean filter:
1. Turn off and unplug turbine.
2. Loosen four thumbscrews (16), remove filter
retainer (15) and pre-filter (22). See Fig. 7.
3. Remove main filter (21) and clean by using one of
the following three methods:
D Tap filter gently on flat surface, dirty side
down.
CAUTION
To prevent damage to filter, do not use compressed
air on a wet filter.
D Direct compressed air (100 psi [7 bar, 70 kPa]
maximum) through filter panel in the opposite
direction of arrows on side of filter (from the
clean side to the dirty side).
D 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.
