TELEHAWK FAULT FINDING CHART
–
PART 1
Symptom Fault Possible Solutions
High power
consumption.
Bale fed too quickly into crossbeater.
Hook rippers too aggressive.
Reduce bed chain speed.
Replace hook rippers with blades.
Fan rotor won't
start. Bale jammed hard against crossbeater. Move the bale away using the unload button.
Material in fan rotor housing jamming fan
rotor.
Hydraulic pipes wrong way around.
Reverse rotor to clear blockage.
Swap hydraulic pipes around.
All sections of
valve block
stop working
Bed chain no
longer
operates or
only very
slowly. Failure
may be
sudden or
Intermittent.
Hydraulic valve problem. Dirt or
contamination in the main inlet/flow divider
slice. Relief valve jammed open. Remove the main inlet/flow divider slice, inspect for
contamination clean and replace. If problem
persists or re
-
occurs regularly replace loader
hydraulic oil with new clean oil.
Loader hydraulic oil pressure low. Check pressure delivered by loader.
Relief valve setting too low. Adjust relief valve (175 bar) or replace if spring
worn.
Dirt or contamination in the 3 way flow
control.
Material jammed between bed chain and
bodywork.
Remove the cartridge, inspect for contamination
clean and replace.
Clear material and check bed chain tension (25 to
50 mm slack in centre of bed).
Bed chain has come off the sprockets. Check sprocket condition, replace the bed chain and
tension it.
Bed chain broken. Check sprocket groove is clean and that the
chamber below the floor is free from obstructions.
Repair chain and refit.
Scraper has jammed sprocket. Reposition/ repair scraper.
Motor not turning. Check connections and loader hydraulics. If motor is
seized, reverse flow to release. Consult your dealer if
this fails.
Sprockets seized. Replace bearings.
Slow
discharge.
Bed chain speed too slow. Increase forward speed of bed chain using speed
control dial.
Insufficient oil flow from loader. Check oil level on
loader or adjust flow rate. Consult dealer if hydraulic
flow cannot be controlled using loader valve.
Material jammed hard against bale
restraint above crossbeater. Move the bed chain in the unload direction until feed
is restored.
Hook rippers worn. Replace hook rippers.
Bale stops
discharging.
Oil getting
very hot.
Crossbeater not rotating. Check pressure switch operating correctly (see page
7).
Bed chain not rotating. See above.
Oil fittings/return pipe restricting flow. Replace small oil fittings with a minimum 3/4” flat
face fittings with a higher flow rate. Fit a free flow
return pipe if the return pipe is greater than 20bar
(290psi)
