stop engine and remove key from the ignition switch.
Chock wheels to prevent ProPass machine from mov-
ing.
2. Loosen conveyor belt tension:
A. Loosen cap screws (item 1) and flange nuts (item
2) that secure adjuster plates (item 3) and flange
bearings (item 6) to conveyor cover.
B. Loosen jam nuts (item 5) and flange head screws
(item 4) that adjust location of adjuster plates which
will loosen conveyor belt tension.
CAUTION
Before disconnecting any hydraulic compo-
nents, operate all hydraulic controls to relieve
system pressure and avoid injury from pressur-
ized hydraulic oil. See Relieving Hydraulic Sys-
tem Pressure in the General Information section
of this chapter.
3. Relieve hydraulic system pressure.
4. Clean conveyor motor and all hydraulic connections
at motor. Label hydraulic lines for assembly purposes.
5. Disconnect hydraulic hoses from hydraulic fittings on
conveyor motor. Allow hydraulic oil to drain from lines
into a suitable container. Put caps or plugs on open hy-
draulic lines and fittings to prevent contamination.
6. Support drive roller (item 15) to prevent it from shift-
ing.
