Before Beginning Repair

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 (EF) or air assist check valve may be plugged, or
the bleed stick (J) may not be tightened. A plugged air
assist check valve prevents air from reaching the under-
side of the plate to assist in raising it from the pail. If the
bleed stick is not tightened no pressure will build.
1. Follow the Pressure Relief Procedure on page 10.
Refer to platen parts illustration on page 28 and dis-
assemble air assist check valve (414) as shown.
2. Clear air assist tube (EF) in platen. Clean all parts of
air assist check valve (414) and reassemble.
3. Remove bleed stick (J) from platen. Push bleed
stick through bleed relieve ports to remove material
residue.
