Equipment Procedure
Air Dryer
Check the air dryer operation. Refer to your air dryer manual for
maintenance procedures and schedules.
Bearings
Every six months, lubricate the fan shaft bearings with two shots
of No. 2 lithium grease from a grease gun. The grease fittings
are on the front of the fan section, between the final filters.
Differential Pressure Gauges
Observe and record the differential pressure gauge readings.
Pressure drop across cartridge filters: 4
− 6-in. wc
Pressure drop across final filters: 1 − 2.5-in. wc
If the pressure drop across the cartridge filters exceeds 6-in. wc,
the filters are clogged. If the pressure drop across the final filters
exceeds 2.5-in. wc, the system will shut down.
Electrical Connections
Check all terminal blocks and junction boxes for loose wires.
Tighten any loose connections and inspect the system wiring.
Replace any wires with damaged insulation.
Exhaust Fan V-belts
Every six months, adjust the tension of the exhaust fan V-belts.
You should not be able to deflect the belts more than 13 − 19 mm
(0.5 − 0.75 in.) (one belt diameter).
Gaskets
Inspect all gaskets and seals for damage. Replace them if they
are damaged.
Guns and Cables
Perform electrostatic resistance checks as described in the spray
gun, and gun control unit or electrostatic power unit manuals.
Powder Feed and Transfer Hoses
Disconnect the hoses from the pumps. Blow the powder out of
the hoses with compressed air. Never blow air through the
hoses toward the pumps. Replace the hoses if they are clogged
with impact-fused powder.
Rotary Sieves
AZO sieves: Every three months, lubricate the lip seals with a
white lithium grease as described in your AZO sieve manuals.
Nordson sieves: Refer to your sieve manual for instructions.
Wheels and Casters
Lubricate the casters and flanged wheel bearings (roll/on-roll/off
booths) with 2 shots of white lithium grease every six months.
