Maintenance
Your NT8000 has been designed with minimum
maintenance in mind, however regular mainte-
nance will ensure trouble free operation for
the life of the implement. It is recommended
that when replacing parts you use genuine
components and fasteners of the same grade
and quality.
Gason require all service personnel read the
Safety section of this manual.
It is also suggested that the following be com-
pleted prior to beginning any service or
maintenance.

Park Tractor and Implement on flat level
ground.

Shut off tractor engine and remove igni-
tion key.

Relieve pressure in hydraulic lines.

Ensure all moving parts are in the resting
position and not lodged. E.g. Tines, Paral-
lelograms, press wheel arms. If lodged,
these components may risk falling into
the resting position.
10 Hours or Daily

Inspect all points and sowing boots for ex-
cessive wear, chips, cracks and bends. Re-
place or repair when necessary.

Check the state of ground tool hardware to
ensure spear points/sweeps remain tight
and in place.

Check sowing boots, for blockages, dam-
age or excessive wear.

Check the tightness of any newly replaced
nuts and bolts after the first 10 hours of
operation, then weekly.

Check all hardware is tight and secure.

Check all hydraulic fittings and compo-
nents for any signs of external leaks.

Check depth control circuit remains
phased (cylinder rod lengths all the same).

Check tension on the tine toolbar mount
and shank hardware. This need only be
done for the first couple of days of opera-
tion until the tine settles in.
100 Hours or Weekly
General:

Grease wing pivots, wheel crank arm piv-
ots and depth control cylinder pivots using
any high quality lithium based extreme
pressure multi-purpose grease, e.g. MOBIL
GREASE XHP 222.

Grease Scari/HydraTILL tine pivots. Gason
recommend a superior lithium complex
multi-purpose grease containing molyb-
denum disulphide, e.g. MOLYBOND OPAL
HI-LOAD (TPG).

Check hubs for bearing play and condition
of seal.

Rotate wheels, feeling for any sideways
movement or notchiness.

Check tyres for wear & inflation pressure.

Inspect all hydraulic hoses for external
wear.

Check the tension on tine shank to pivot
bracket hardware i.e. M20 set screws and
nuts.

Check ground tool wear and/or damage -
replace as required.
Note: When replacing ground tools, it is rec-
ommended to replace the relevant hardware
with genuine new parts at the same time. Re-
fer to the Spare Parts section of this Manual
for details.
500 Hours or Seasonally
The amount of maintenance required will de-
pend on the area of seeding and the condi-
tions.

Grease all main axle hub bearings. Be care-
ful not to over grease.

Check the tension on fasteners across the
implement, especially those attaching
tines.
Cleaning and Storage
To maximize the life of your Implement, Gason
recommend that basic cleaning and protection
of some areas be performed at the end of the
working season.
