5.9 MANUAL ROLLER OPEN PROCEDURE
To raise the upper roller in a safe manner, use the turnbuckle to raise the roller bridge as described in the
following procedure.
a. Ensure the machine is in
safe condition
before beginning
this procedure (see 2.2)
b. Remove the bridge guard: remove the bolts that hold on
the bridge guard, and store them in a safe area.
c. Find the turnbuckle stowed on top of the
hopper. Remove the lower link pin, and turn
out the turn buckle so that it extends to the
bridge clevis.
d. Mount the turnbuckle on the bridge clevis,
ensure the turnbuckle is equally extended
at both ends. Use the link pin to secure the
turnbuckle in place.
e.
Free up the roller tension springs: find the
spring yoke attached to the upper roller and
remove the latch pin, then carefully remove
the 2 nut handle adjusters.
f. Repeat for the opposite side.
g. The upper roller bridge is free to move, be-
gin rotating the turnbuckle so that the bridge
begins to lift.
h. When the roller is at its maximum, engage
the roller lock plungers located on each side
of the roller. This will lock the roller in place.
