Feed rake conveyor
Installing the intermediate floor
1. Push the intermediate floor into the feed rake
conveyor.
2. Using a suitable tube, raise the intermediate floor
and bolt it into position at the sides.
3. Remove the two straps.
4. Place the feed rake chains on the bottom roller
so that the feed rake slats (E) are correctly
positioned, i.e. staggered with one another.
5. Install the chain connectors and secure with new
split pins.
6. Tensioning the feeder chains:
Once the clamping bolt (A) and the lock nut (C)
have been slackened, the feeder chains may be
tensioned using adjusting nuts (B).
Tension the chains evenly on both sides and only
adjust to such an extent that the feed rake slats
are just touching the runners (G).
The tension of the chains can also be checked
with a cutterbar fitted, using the inspection
door (P) provided on the feed rake conveyor.
7. Refit the guard on the left-hand side and the
universal coupling.
8. Bolt down the dust guard, the right-hand end
piece, the left-hand guide plate and the inspection
doors.

Replacing the runners
Raise the feed rake conveyor and support it safely.
Using a suitable tube raise the front roller and secure it
using wooden blocks (H).
Remove the mushroom head bolts and pull them out
inside the feed rake conveyor.
Pull the runners (G) towards the front and replace by
new ones.
Installing the runners:
CAUTION!
Tape the mushroom head bolts to the runners.
Slide the runners up into the feed rake conveyor, then
bolt into position.
