Flush Before Using Equipment

The pump was tested with lightweight oil, which is left in
the fluid passages to protect parts. To avoid contaminat-
ing your fluid with oil, flush the pump with a compatible
solvent before use. See your pump manual for flushing
directions.

Maintenance Procedures

To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief procedure.

Platen Maintenance

See F . 10. If the platen does not come out of the pail
IG
easily when the pump is being raised, the air assist tube
(F), or check valve may be plugged. A plugged valve
prevents air from reaching the underside of the plate to
assist in raising it from the pail.
1. Relieve pressure. Refer to parts illustration on page
58 and disassemble air assist valve as shown.
2. Clear air assist tube (F) in platen. Clean all parts of
valve and reassemble.
3. Remove bleed stick (EK) from platen. Push bleed
stick through bleed relieve ports to remove material
residue.
