Safety is vital for all repair work on the machine. Always observe the
following points, plus those under Safety First in the instruction manual.
When replacing cylinders, always fill new cylinder with oil before
pressurising system. We recommend fitting cylinder to frame first, fill with
oil, before completing fitting at top.
Never perform maintenance unless the machine is lowered onto the ground,
the tractor brake is applied, the engine switched off and ignition key removed
to prevent accidental start and injury.
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.
