TOMAHAWK C12 FAULT FINDING CHART – PART 1
Symptom
Fault
Possible Solutions
High power
Consumption.
Bale fed too quickly into the rotor or worn
hammers.
Bale chamber speed too high
Rotor housing / Screen blocked
Reduce bale chamber speed.
Remove blockage
Belts slipping on
rotor drive.
Incorrect belt tension
Tension the rotor drive belts according to section
12.8.2
Rotor won't start. Blockage in the rotor housing
Remove blockage within the housing
Too high a PTO speed
Start PTO in 540rpm until it run smoothly & re-start in
1000rpm then blockage clears.
Shear bolt has failed
Replace shear bolt
Belts slipping on rotor
Tension the rotor drive belts according to section
12.8.2
Bale chamber no
longer
operates or only
very
slowly.
No power supply
Check Bluetooth is connected & investigate power
supply.
Auxiliary stop button depressed.
Release stop button.
Oil tank isolation tap closed.
Open tap.
Material jammed between bale chamber
and bodywork.
Check edges of bale chamber for material blockage.
Maximum tub speed not calibrated
correctly.
Follow calibration procedure in section 9.3.
Bale chamber chain has come off
sprockets.
Check sprocket condition, fit the chain and tension it.
Bale chamber chain broken.
Check sprocket condition and replace chain.
Bale chamber chain is slipping
Check tension of both bale chamber drive chains.
Motor not turning.
Check connections. See hydraulic valve fault solutions
Dirt or contamination in the proportional
flow slice or relief valve controlling the
Bale Chamber speed.
Remove the proportional cartridge and relief valve from
the flow control slice inspect for contamination clean
and replace. If problem persists or re occurs regularly
replace filters and hydraulic oil with new clean ISO
HV46 grade oil.
Slow
Discharge.
Bale chamber speed too slow.
Increase rotation speed of the bale chamber (see
section above).
Material lodged against side of bale
chamber.
Reverse tub for at least two rotations to remove
blockage then resume chopping.
Blockage in rotor housing.
Unblock the rotor housing.
Screen blocked.
Remove blockage from screen.
Hammers are worn.
Turn or replace hammers.
Rotor speed low.
Check tractor PTO Speed is 1000 RPM.
Bale stops
discharging.
Rotor not rotating.
Replace shear bolt in PTO shaft
See solutions in rotor section .
Bale chamber not rotating.
See solutions in Bale chamber section above.
Conveyor is not moving.
See solutions in Conveyor section .
