Safety is vital for

all

repair work on the machine. Always observe the fol-

lowing points, plus those under Safety First in the instruction manual.

All maintenance and repair work can only be performed when the machine is
lowered to the ground or locked in transport position, tractor is braked, en-
gine 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 pre-
vent mechanical breakdown and injury to person.
