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).

Clean any paint on outer surface of front

and rear housing with a soft cloth damp-

ened with solvent. (See “Warning” on

avoiding the use of cleaning solvent con-

taining d-Limonene.)

Remove the front shroud and check for any

signs of solvent or paint leakage. Clean as

required as required.

Remove bell cup and soak in solvent for 1-2

hours. Clean with a soft brush as required.

Remove from cleaning solution and blow

dry before replacing.

With bearing air off, carefully inspect the

feed tube tip and clean any paint build-up

that has occurred on the feed tube tip. Us-

ing a pen light, determine if there is build-up

of paint in the motor shaft and/or around

the paint feed tube. If so, remove the motor

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.

components, including internal portion of

shroud.

Reinstall bell cup and front shroud, replace

cover on the outer housing. (Refer to “Dis-

assembly Procedures” in the “Maintenance”

section for definite instructions.)

Recheck bell cup tightness. Torque to 50-

70 lbs•in (5.65-7.91 Nm).

Bell cup failure due to inadequate cleaning or

handling will not be covered under the War-

attempted for any reason.
