Weekly Maintenance (Prior to Start or End of
Production Week)
•
Monitor rotational speed of all belts at the
speed control. Investigate cause if abnor-
mal.
•
Monitor high voltage and current output indi-
cated on the MicroPak display. Investigate
cause if abnormal.
•
Check paint flow on all bells at minimum
and maximum specified settings by taking
beakered readings.
•
Check solvent flow by opening solvent valve
and taking a beakered reading (should be
within approx. 10% of target flow rate).
•
Paint residue found in the shaping air holes
is not acceptable and must be removed pri-
or to applicator use (see “Cleaning Shaping
Air Holes” in the “Maintenance” section).

taining d-Limonene.)

signs of solvent or paint leakage. Clean as

assembly following the disassembly proce-
dures and clean out the inside diameter of
the motor shaft using a tube brush and sol-
vent. Clean the outer surfaces of the feed
tube.
