LOWERING FEEDER
1. Before lowering the feeder, make sure that the
area under the feeder is clear of tools or foreign
objects.
2. Release safety prop carefully. If feederhas dropped
firmly down onto safety prop, it will be necessary to
raisethe feeder. After raising the feeder,
tum engine
offand release safety propas instructed.
3. Lower feeder, but not under pressure. Allow
feeder to come down with engine not running.
4. Fold side panels back with same in and out knuckle
motion used to raise
them.
5. Replace the hold down bolts on each side panel,

FEEDER FLIGHT CHAIN ADJUSTMENT
1. Raise feeders.
2. Secure safety prop to prevent feeders from
accidentally lowering.
3. The feeder conveyor should run smooth when feeder
chain is properly
adjusted. These chains should be
adjusted every 100 hrs.,to maintain smooth operations.
If irregular movement of the conveyor occurs, this is
generally a sign that an adjustment is needed. Follow
the procedures below in making
this adjustment.
a. Refer to figure 33 and loosen the lock nut.
b. Turn adjustment bolts alternatively on both sides of
the feeder. You can feel the pressure on the chain
as you tighten the bolts.
(VVe recommend turning
one bolt one
half tum then the other bolt one half
turn. Continue alternating tightening until chains
are tight).
c. After the feederchain tension is set, tighten lock nuts.
d. If the adjustment bolts have been run out, it will
be necessary to remove a link in the feeder chains and
add a half link. This repair should bringthe adjustment
boltsbackto fulltravel.

FIGURE 33
AUTOMATIC TRACK ADJUSTMENT
General
Hydraulic Adjustment Cylinders provide even tension
on track which prevents excessive wear to paver
undercarriage. This feature, however, will require the
operator when backing with load to maintain at least
one half throttle setting. Hydraulic pressure below
one half throttle is not adequate to maintain track
adjustment.
FAILURE TO MAINTAIN ADEQUATE THROTTLE
SETTING
MAY CAUSE IMPROPER ADJUSTMENT
TO TRACK.
! CAUTION!
WHEN BACKING THIS MACHINE WITH LOAD, MAIN-
TAIN AT LEAST A ONE HALF THROTTLE SETTING:
FAILURE TO DO SO MAY CAUSE IMPROPER TRACK
TENSION, RESULTING IN POOR PERFORMANCE
AND DAMAGE.
