MAINTENANCE

Service

IMPORTANT! All types of repairs may only be carried out by
authorised repairmen. This is so that the operators are not
exposed to great risks.
After 100 hours of operation, the message "Time for
servicing" is displayed. The entire equipment shall then be
taken to an authorized Husqvarna dealer for servicing.
Maintenance
IMPORTANT! Inspection and/or maintenance should be
carried out with the motor switched off and the plug
disconnected.
Oil change hydraulic unit
There is a magnetic plug on the underside of the tank for
draining the hydraulic fluid. Clean the magnet.
!
Open the screw cap on the tank and fill with hydraulic oil with
a viscosity of 68. Make sure that the fluid level is about 10 mm
below the max. mark on the level indicator.
About 16 litres of hydraulic fluid is required when changing.
Filter replacement
To change the filter, remove the tank cap after loosening the
twelve screws. Loosen the three screws for the filter housing
cover and remove it as well. Lift out the old filter cartridge and
press in the new one, making sure it engages with the end of
the tube in the bottom of the housing.
Daily maintenance
Regularly check:
• The hydraulic fluid level in the hydraulic power unit, to
make sure it lies between the marks on the level glass.
• Check the tyre pressures.
• Any abnormal noises.
WARNING! Remember that oil can pose a
hazard to health and the environment.
