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 380 E)
Damages to power cables or blown fuses Check the power cables, install the approp-
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 380)
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 380)
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.
