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 manu-
facturer.
4.
When servicing the machine, place it on a level
surface and ensure that it cannot be moved.
5.
Turn off the tractor engine and disconnect the
PTO drive shaft before beginning service or mainte-
nance actions.
6.
Before any maintenance work, turn the main
power switch of the tractor to OFF.
7.
Take out the key from the tractor's ignition for the
duration of the servicing or maintenance. Check that
the power is off from the machine you are working
on.
8.
Before disconnecting the hydraulic hoses from
tractor, ensure that the hydraulic system is
depressurized.
9.
Observe the service intervals and annual safety
inspections.
10. All spare parts and equipment must fulfill the manu-
facturer's requirements. This can be guaranteed by
using original parts.
11. Put all safety devices back into place immediately
once servicing or maintenance is complete.
When lifting the machine, check that
the lifting/hoisting equipment is in
perfect working order. Check the
weight of the machine before lifting
ATTENTION
it.
Choose lifting trajectories so that
they do not cause any danger.
Many countries have specific legislation on lifting,
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 damage to people or property.
2.
Never mix different liquids or oils.
3.
Always follow the manufacturer's lubrication
instructions.
4.
Use control equipment carefully until the hydraulic oil has
had time to reach its operating 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 those 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 lines are not damaged. Check that all
protective 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 requirements. 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 val-
ves, 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 cleaning parts.
8.
Do not attempt to carry out repairs that you are not fully
familiar with.
9.
Never carry out repairs of the hydraulic circuit when the
system is pressurized. When pressurized, the oil spray
can penetrate the skin and cause mortal danger.
10. Never work below a device or component that is only
being held up by hydraulics. Use separate supports
when carrying out maintenance or repairs. Do not
disconnect cylinders or their valves until the machine
is well supported.
11. Most hydraulic oils do not evaporate easily. Risk factors
include hot oil, spills and oil mist (pressurized).
12. If oil gets into your eyes, rinse with plenty of water
and contact a doctor.
