CRANE RANGE

• Do not start the tractor without having disconnected the hydraulic pressure to the crane.
• Support the crane during maintenance work to ensure that no parts are dependent on the hydrau-
lic cylinder.
• Pinpoint the fault before carrying out repair work, so that you do not open the hydraulic system
unnecessarily.
• If possible, engage trained service personnel for any work on the machine’s hydraulic functions.
• The crane’s hydraulic valves are supplied with both main pressure limiters and choke valves to pre-
vent the crane from being overloaded. Modifications may not be carried out under any circum-
stances.
• The crane’s hydraulic hoses and pipes must always be kept in good condition. Replace the relevant
components in the event of any defects. Defects in hoses, for example, can result in a high-pressure
jet of oil that can penetrate skin on contact and cause a serious infection. If this occurs, consult a
doctor immediately.
Note: When the hydraulic system is brought back into use following repair work, be extremely carefully.
Air in the system can result in unforeseen crane movements. You should therefore bleed the system by
operating all the cylinders to their limit positions a few times.
Note: When using the hydraulic functions, you should use them gently. Do not operate them at full
speed from one position to the next. This can cause damage to hydraulic seals and other parts.

Replacing hydraulic components
Always use genuine parts when it comes to hoses, seals, bolts, etc. Using genuine parts guarantees us-
age that is as fault-free as possible.
REPLACING SEALS
If a cylinder seal is damaged, replace all the seals in the
cylinder.
Take care when replacing seals to ensure you do not
damage them during installation.
1. Once the old seals have been removed, carefully
clean the cylinder and piston rod before installing
the new seals.
2. Lubricate the new seals with hydraulic fluid.
3. If possible, engage the specified service personnel
for any work on hydraulic functions.
