Replacement and repairs

Safety is vital for all repair work on the machine. Always observe the following
points, plus those under Safety First in the instruction manual.
All maintenance and repair work can only be performed when the machine is low-
ered to the ground or locked in transport position, tractor is braked, engine stopped
and ignition key removed to prevent accidental start.
Particular attention must be paid to safety when repairing hydraulics. Before
commencing work, depressurise hydraulic system and support part being worked
on.
Always ensure hydraulic system is bled after repairs and before use to prevent
mechanical breakdown and injury to person.
Replacing gaskets on NSH system cylinder
1. Support the machine so that the tines are clear of the ground.
2. Depressurise the NSH system.
3. Disconnect hoses and pins, and remove cylinder.
4. Fit new cylinder, replace pins and split pins.
Bleed the system by applying pressure up to 150 bar and then depressurising to 0
bar again. Repeat several times.
NEVER try to dismantle the accumulator in the system. It is charged with nitrogen
gas under high pressure. This unit must be serviced by an authorised DALBO ser-
vice engineer only.
