WARNING:
High Pressure Fluid Hazard. Stop the pump and relieve air
and fluid pressure before performing the following procedures. Failure to
observe this warning could result in personal injury or even death.
Daily
1. Remove and clean the high pressure fluid filter screen, unless
experience indicates less frequent cleaning is adequate. Install a clean
screen and soak the dirty screen in solvent. Discard any ruptured or
distorted screens.
2. Check the solvent chamber fluid level. Drain and replace the solvent
chamber fluid when the level drops 32-mm (1
1
/
4
-in.) below the top of the
solvent chamber, or if the solvent chamber fluid becomes contaminated
with coating material.
Fill the solvent fluid chamber with new fluid to 12.7 mm
(1
/
2
in.) from the
top. Use type-T solvent chamber fluid for waterborne coatings and
type-K solvent chamber fluid for solventborne coatings.
3. Drain the air filter. Remove the air filter bowl and dump out any
remaining water. Remove the air filter element, unless experience
indicates less frequent cleaning is adequate. Wash the element in
soapy water, then rinse, dry, and reuse it.
4. While the pump is running, check the air lubricator oil level and delivery
rate (1 drop every 15
−
20 strokes). Fill if necessary, using only Nordson
vitalizer oil or an approved substitute.
Weekly
1. Clean the exterior of system components with a cloth dampened with
solvent or soapy water. Do not soak any components in solvent. Hose
coverings and seals may be affected by some solvents.
2. Check all ground connections with an ohmmeter. Make sure the
resistance from pump to ground is less than one megohm.
