12.1 General
troubleshooting
PROBLEM:
SOLUTION:
1.
Weighing display won’t work properly
Check section 12.2 on weighing.
2.
VFC-door does not move
Check hydraulic hoses and ensure that valves are
open.
Check tractor hydraulic oil level.
Check ram condition and ensure that pins are
secure.
3.
VFC-door drops during mixing
Insufficient hydraulic pressure
—
check spool valve
on tractor or fit non-return valve in line.
Check ram for signs of leakage.
4.
VFC-door closes unevenly/sticks
Rams operating out of sequence. Move door to fully
open position and hold level to allow oil to bypass
the ram when the door is fully open and level.
Repeat fully closed, until the door is even.
5.
Excessive shear bolt breakage
Machine overloaded.
Driving chain too loose
—
check condition and
adjust idler springs.
Feed-out too fast
—
open feed-out door, slowly at
first, then open fully.
Turn paddle a few times before opening the feed-
out door to avoid putting a huge load on the
machine, especially after feed has settled in the
body of the machine.
Run machine slower.
For non-bale handler models, never load bales
directly down on the paddle in one go. Always chop
up into at least four pieces.
6.
Noisy operation
Oil chains liberally. Adjust tension on chains.
Grease all nipples.
Check chain alignment.
7.
Feed is not properly mixed
Insufficient mixing time.
Loading materials in wrong order.
Not enough time given for chopping.
Overloading of machine.
8.
Feed-out is too slow
Check condition of paddle rubbers.
Slow down tractor ground speed.
Reduce engine revs to give paddle more time to push
material into auger. Ensure material is fully chopped
before unloading.
