5.2 TROUBLESHOOTING

PROBLEM
The machine does not react to control
handle commands.
Machine vibrates excessively
Machine is overheating.
No hydraulic component is operational
and the control indicators on the valves
do not light when you move the control
handle.
The machine became loud.
Discharge conveyor is not operating.
Feed conveyor belt is not operating or
is slipping and the gauge shows the
pressure (90-100bar / 1305-1450 psi)
The conveyor belt is pulling in one
direction. Applicable to both feed and
discharge conveyors.
Hydraulic cylinder is leaking.
POSSIBLE CAUSES
Electrical cable is not connected.
Electric cable connected, no voltage in the socket or
wrong polarity.
RESET button wasn't pushed.
Improper tractor and machine postion is causing
vibrations of the P.T.O. shaft.
Worn-out P.T.O. shaft.
Not enough oil in the reservoir.
Worn-out oil.
Clogged oil filter, the filter gauge is in the red zone
when the oil is warm.
Excessive P.T.O. shaft rotating speed is causing
increased oil flow, higher losses and heating of the
oil.
Splitting cylinder cannot return in the primary posi-
tion as too much sawdust and wood particles have
accumulated behind the cylinder. This is also indi-
cated by higher pressure when idling.
Overheating and the loss of splitting force can be
caused by internal splitting cylinder leakage.
Interrupted connection between angle multiplication
gear and hydraulic pump.
Excessive P.T.O. shaft rotating speed.
Not enough oil in the multiplication gear.
P.T.O. shaft with built-in clutch is causing the noise. We do not recommend using P.T.O. shafts with clutches.
Improper tractor and machine positioning; vibrations
are also present.
P.T.O. shaft is not lubricated.
Before staring up you didn't push the RESET button. Before every startup or after opening the safety cover, it
Conveyor belt speed regulator is set in the lowest
position.
Conveyor belt is not moving although driving roller
is spinning. Conveyor belt is not tensioned enough.
Piece of the wood is blocking the rotation.
Hydraulic pipes for driving the log loader cylinders
are connected improperly and the oil flow is inter-
rupted.
Log loader is not connected and quick couplings
under the table are loose.
The roller is slipping, the belt isn't tensioned enough. Tension the belt.
Log is too heavy and getting stuck.
Bad positioning of the driven rollers.
Damaged seal.
Damaged piston rod.
SOLUTION
Connect the cable to the tractor outlet.
Switch the tractor lights on, check the fuses (in the mac-
hine el. box and on the tractor), check the polarity.
Before every startup or after opening the safety cover it is
necessary to push the green RESET button (4.1) to re-
store all machine functions.
Reconnect the tractor and the machine according to the
instructions (Chapter 3).
Check and replace P.T.O. shaft if necessary.
Add suitable quality oil (5.5).
Check the oil quality and replace the oil, if necessary.
Replace the oil filter insert.
Check the P.T.O./shaft rotating speed; it should be 400 to
430 rpm.
Lift the splitting cylinder cover and clean the wood re-
mains. Afterwards clean the area under the machine
regularly (4.6).
Servicing may be required due to possible loosening of
the piston in the cylinder.
Replace the sprocket which connects multiplication gear
and hydraulic pump (servicing).
Check the P.T.O./shaft rotating speed, which should be
400 to 430 rpm.
Check the oil level and replace it, if necessary (5.7)
Use the regular P.T.O. shaft or P.T.O. shaft with wide
angle linkages on both sides which ensure constant trans-
fer of rotating speed.
Reconnect the tractor and the machine according to the
instructions (Chapter 3).
Lubricate the shaft according to P.T.O. shaft instructions.
is necessary to push the green RESET button (4.1) to
restore all machine functions.
Set higher speed using the regulator (Figure 8c).
Discharge conveyor valve (T-Figure 5) must be turned
down totally to prevent oil from exiting the cylinder
which tensions the belt.
Remove the foreign piece and regularly clean the area
under the driving roller.
Check the pipe connectors and push the couplings (3.3)
deep enough.
Connect both couplings with the connecting pipe (3.3).
Saw the log in shorter pieces.
Set the driven roller so the conveyor belt will run in the
middle.
Seal replacement (servicing).
Cylinder replacement (servicing).
