5.8 TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSES
SOLUTION
The machine does not react to movements
of the sawbar activation handle
Check the machine drive (P.T.O. shaft or
electric motor must be connected and in
operation, otherwise the pump and
chainsaw drive do not work)
Check the level of the oil in the tank
Damaged control mechanism
Repair or replace the control mechanism
⊗
Electric motor does not start or it often
shuts down (RCA 320-2 E)
Damages to power cables or blown fuses
Check the power cables, install the approp-
riate fuses
Motor protection is shutting the motor
down.
Power cable size is not appropriate, the
machine is overloaded
Hydraulic oil is overheating
Not enough oil in the reservoir
Check the oil level and add more if
necessary.
Worn-out hydraulic oil
Change the hydraulic system oil.
Clogged oil filter
Clean the oil filter. (5.5)
Clogged hydraulic pipes
Check the hydraulic pipes and clean them if
necessary.
Splitting cylinder did not reach the final
position.
Reverse the cylinders, clean the splitting
chute
High Outside Temperature
Install the oil cooler
Machine is loosing power
Hydraulic oil is overheating
Refer to “ Hydraulic oil is overheating“
Not enough oil in the reservoir
Check the oil level and add more if
The machine is overloaded
Remove the overloading causes
Excessive power consumption during
sawing
The chain is dull
Sharpen or replace the chain
The chain is not properly tensioned
Tension the chain
The chain is covered with resin
Clean the chain using the solvent (i.e. Nit-
ro-Solvent) or replace the chain
Louder operation of the machine
Revolution speed of the tractor is exceeded
(RCA 320-2)
Consider the recommended revolution
speed.
Clogged filter
Clean the filter
Not enough oil in the reduction gear
Check the oil level and add more if
necessary.
The machine is not connected to the tractor
– only P.T.O. shaft is connected
(RCA 320-2)
Connect the machine to the tractor or posi-
tion the tractor
perpendicular
to machine
P.T.O. shaft is not lubricated
Lubricate P.T.O. shaft appropriately
Hydraulic hoses are overheating
Not enough oil in the hydraulic system
Check the oil level and add more if
necessary.
Worn-out hydraulic oil
Replace the hydraulic system oil. (**)
Hydraulic cylinder is leaking
Seals are worn-out
Replace worn-out seals.
Damaged piston-rod
Replace the cylinder
In-feed conveyor is slipping or not opera-
ting
Conveyor belt is not tensioned enough
Tension the conveyor belt
Not enough oil in the hydraulic system
Check the oil level and add more if
necessary.
