Hydro-pneumatic accumulator
A hydro-pneumatic accumulator contains nitrogen under
pressure (risk of suffocation in closed rooms).
Repairs, maintenance or commissioning may only be
carried out by competent persons. Wait for the
accumulator to cool down before handling it. Only use
nitrogen to precharge it.
Depressurize the gaz and oil sides of the hydraulic
accumulator before opening it.
It is strictly forbidden to weld, grind or drill onto a hydro-
pneumatic accumulator.
Make sure that the accumulator and its' fittings are in
good condition.
Precautions for maintenance and repair
work
Before leaving the tractor or before adjusting,
maintaining or repairing the machine, disengage the
PTO drive, turn off the engine, remove ignition key and
wait until all moving parts have come to a complete stop
and apply park brake.
Rest the machine on the ground, release the pressure
from the hydraulic circuit and leave the machine to cool
down.
Make sure that the parts of the machine that need to be
lifted for maintenance or repair work are firmly propped
up.
Before any work is done on the electric circuit or before
any electric welding is carried out on the attached
machine, disconnect the machine from the tractor
electrical circuit. Also disconnect alternator and battery
terminals.
Repairs on elements under pressure or tension (springs,
pressure accumulators, etc.) must only be carried out by
competent persons with regulation equipment.
Wear the appropriate protective clothing for the work in
hand (gloves, shoes, goggles, helmet, ear defenders,
etc.).
Do not solder, weld or use a blow torch near fluids under
pressure or inflammable products.
For your own safety and for correct machine operation,
only use original manufacturer parts.
It is strongly recommended to have your machine
checked by your Kuhn dealer after each season,
especially tools and their attaching hardware.
