MAINTENANCE AND SERVICE
Cleaning
Cleaning method
The cleaning method varies depending on type of
contaminants and how dirty the machine is. A mild
degreasing agent can be used. Avoid skin contact.
Bear the following in mind when using high-pressure
washing:
• High-pressure washing with the wrong nozzle or high
pressure can damage electrical components, electric
cables and hydraulic hoses.
• The high pressure jet can damage seals and lead to water
and dirt permeating into the machine, resulting in serious
damage.
• Stickers can be washed away.
• The surface finish can be damaged.
Cleaning of components
There are a number of components that require special
consideration when cleaning.
Hydraulic tank
Place a plastic bag over the tank’s air filter and seal it with a
rubber band to avoid water getting into the tank.
Cooler
Allow the cooler to cool down before cleaning. Use
compressed air to clean the air fins. If necessary, use high-
pressure washing and degreasing agent. Incorrect use of
high-pressure washing or compressed air can distort the
cooler’s fins and thereby impair the cooling capacity.
• Max. pressure 100 Bar.
• Spray directly towards the cooler, in parallel with the fins.
• Keep a distance of at least 40 cm between the cooler and
the nozzle.
Electrical components
Clean electric motor, electric cabinet, terminals and other
electrical components with a cloth or with compressed air. Do
not spray water at electrical components. Dry the remote
control with a damp cloth. Never use high-pressure washing.
Blow clean internally using compressed air.
After washing
• Lubricate all the machine’s lubrication points.
• Blow electrical terminals dry using compressed air.
• Exercise caution when the machine is started after
washing. If any components have been damaged due to
moisture, the machine’s movements can be defective.
!
CAUTION! Turn off the motor. Disconnect the
power cable and place it so that it cannot be
connected by mistake.
The area around the machine must be free of
dirt in order to minimize the risk of slipping.
Use appropriate personal protective
equipment.
When cleaning the machine there is a risk of
getting dirt and harmful substances in the
eyes, for example.
Dirt and harmful substances can be released
from the machine when using high pressure
equipment.
High-pressure jetting using water or air can
permeate into the skin and cause serious
injury. Never aim a high-pressure jet towards
the skin.
NOTICE! High-pressure washing and compressed air
should be used with extreme caution, incorrect use can
damage the machine.
