General

WARNING! The user must only carry out the
!
maintenance and service work described in
this manual. More extensive work must be
carried out by an authorized service
workshop.
Inspection and/or maintenance should be
carried out with the motor switched off and
the plug disconnected.
The life span of the machine can be reduced and the risk of
accidents can increase if machine maintenance is not carried
out correctly and if service and/or repairs are not carried out
professionally. If you need further information please contact
your nearest servicing dealer.

Daily maintenance

Check that the machine's safety equipment is
undamaged. See instructions in the section "Machine's
safety equipment".
Check that the cord and extension cord are intact and in
good condition.
Check the hydraulic oil level in the power pack. The high
pressure jet can damage seals and lead to water and dirt
permeating into the machine, resulting in serious damage.
Always clean all the equipment at the end of the working
day. Use a heavy-duty hand-held brush or a large paint
brush.
Make sure to keep the connectors and pins clean. Clean
with a rag or brush.
NOTICE! Do not use a high pressure washer to clean the
machine.
Check the tire pressures.

Oil change

WARNING! Remember that oil can pose a
!
hazard to health and the environment.
There is a magnetic plug on the underside of the tank for
draining the hydraulic oil. Clean the magnet.
Open the screw cap on the tank and fill with hydraulic oil
with a viscosity of 46. It is recommended to use a
hydraulic oil with a viscosity of 68 in warmer climates.
Make sure that the oil level is about 10 mm below the max.
mark on the sight gauge.
About 16 litres of hydraulic oil 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.
