
Safety is vital in the performance of 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 the new cylinder with oil before pres-
surising system. We recommend fitting the cylinder to the frame first and fill-
ing it with oil, before completing attaching at the top.
All maintenance and repair work on the machine may only be performed
when it is lowered to the ground or locked in transport position, the tractor is
braked, engine stopped and ignition key removed to prevent inadvertent
startups.
Particular attention must be paid to safety when repairing the hydraulics. Be-
fore commencing work, depressurise the hydraulic system and support the
part being worked on.
Always ensure that air is bled out of the hydraulic system after repairs and
before use to prevent mechanical breakdowns and personal injuries.
