Maintenance
WARNING:
Allow only qualified personnel to perform the following tasks.
Follow the safety instructions in this document and all other related
documentation.
WARNING:
Stop the pump and relieve air and hydraulic pressures before
disconnecting air or fluid hoses, or before disassembling any equipment.
Daily
Do the following daily:
1. Make sure that all conductive equipment in the spray area, including the
pump and waste container (11), are securely connected to a true earth
ground.
2. Drain the air filter (2). Check the filter element and replace it if
necessary. Open the drop leg drain valve and drain collected moisture.
3. Clean the fluid filter (6) screens. Replace them as necessary.
4. Check the level of solvent chamber fluid in the solvent cup (3). The
solvent chamber fluid should be 12 mm (
1
/
2
in.) from the top. Add more
solvent chamber fluid as needed.
NOTE:
Coating material leaking past the upper packing gland will discolor
the solvent chamber fluid and cause its level to rise. A small amount of
leakage is normal.
If the solvent cup fills quickly and overflows,
relieve the hydraulic
pressure
, then tighten the solvent cup approximately
1
/
8
to
1
/
4
turn
clockwise with a round steel bar or screwdriver. This should compress the
packings and stop the leaking. If the leaking continues the packings need
to be replaced. Both upper and lower packings should be replaced at the
same time.
As Needed
Flush the pump and system with a compatible cleaning solution. Change
the solvent chamber fluid regularly. Clean the exterior of the pump.
