MAINTENANCE
1. The machine may only be serviced and
repaired by professionals.
2. Electrical and hydraulic faults may only be
repaired by authorized professionals.
3. In cases requiring welding, contact the
manufacturer.
4. Turn off the tractor engine and dis-
connect the universal joint before begin-
ning service or maintenance actions.
5. Before any maintenance work, turn the
main power switch of the tractor to OFF.
6. Take out the key from the tractor's ignition
for the duration of the servicing or mainte-
nance. Check that the power is off from the
machine you are working on.
7. Before disconnecting the hydraulic hoses
from tractor, ensure that the hydraulic
system is depressurized.
8. When servicing the machine, place it on a
level surface and ensure that it cannot be
moved.
9. Observe the service intervals and annual
safety inspections.
10. All spare parts and equipment must fulfill
the manufacturer's requirements. This can
be guaranteed by using original parts.
11. Put all safety devices back into place imme-
diately once servicing or maintenance is
complete.
When lifting the machine,
check that the lifting/hois-
!
ting equipment is in per-
fect working order. Check
the weight of the machine
CAUTION!
before lifting it. Choose lif-
ting trajectories so that they do not cause any
danger.
Many countries have specific legislation on lif-
ting, hoisting cables and hoists. Always comply
with local safety regulations.

OILS AND LUBRICATION
1. Always use the oil types recommended by
the manufacturer. Other types of oil may
cause faults or improper operation of the
equipment, which could lead to serious da-
mage to people or property.
2. Never mix different liquids or oils.
3. Always follow the manufacturer's lubri-
cation instructions.
4. Use control equipment carefully until the
hydraulic oil has had time to reach its opera-
ting temperature.
SAFETY INSTRUCTIONS FOR HYDRAULIC
CIRCUITS
1. Work on hydraulic equipment may only
be carried out by professional hydraulic
engineers.
2. Be cautious when using the equipment in
cold conditions.
3. Check the machine for leaks. Do not use the
machine if there is a leak from any system.
Check all hydraulic hoses – particularly tho-
se which are bent during use – and replace
any that are in poor condition or have leaks.
Ensure that all joins are tight and that the li-
nes are not damaged. Check that all protec-
tive caps and filler caps are closed properly.
Check the hose sheathing for damage.
4. Check that all hose connectors, lengths
and qualities comply with applicable requi-
rements. When replacing or repairing hoses,
use original parts or hoses and connectors
recommended by the manufacturer. Check
particularly that the pressure classes of the
hoses and connectors are suitable to the
operating pressure levels.
5. Check that all safety devices such as
pressure relief valves, etc., are in place and
work properly. Familiarize yourself with their
use. Safety systems may never be bypassed.
6. Check the main hydraulic parts daily, and
always after a fault. Replace any damaged
parts immediately.
7. If a component is damaged, clean it before
repairing it. Do not use solvents when clea-
ning parts.
