3.3 Disconnecting the hydraulic
hoses
Check the machine's hydraulic system
is not pressurised before disconnecting
the hydraulic hoses. Risk of extremely
dangerous oil spray while under high
pressure .
Stop the engine. Neutralise any overpressure in the
machine's hydraulic system by moving all hydrau-
lic controls forward and backwards several times.
Disconnect the hydraulic hoses from the machine
output.
Install the plugs on the hydraulic outputs.
3.4 Mechanical disconnection
To facilitate the plough standing stable after dis-
connection the plough blade must be set angled
backwards before disconnection.
Mechanical disconnection is the connection de-
scribed above in reverse.
4 MAINTENANCE
4.1 Actions before operation
If the plough displays any faults during the checks
below, it must not be used before the faults have
been rectified.
• Check that all hydraulic hoses are sealed and do
not show any signs of wear or other damage.
• Check that the hydraulic cylinders are sealed.
• Check that there are no cracks in the plough
blade, along the hydraulic cylinder mountings
or in other locations.
• Check that the scraper blade has at least 5mm
remaining to the underside of the steel holder. If
the distance is less the scraper blade must be re-
placed or turned.
4.2 Lubrication
The plough's mechanical joints must be lubricated
with universal grease after 25 hours of operation
and before long term storage.
The plough has grease nipples in the following lo-
cations. The grease nipples are shown in fig. 1.
• A lubricating cup from the front for the centre
bolt (A).
• Four lubricating cups from the rear for the
plough blade bearing in the centre bolt (B).
• Four lubricating cups at the end of each hydrau-
lic cylinder (C).
