Recommendations
Lubricants and
Anti-Corrosive Agents:
Use the lubricants specified for en-
gine and gearbox (see “Specifica-
tions”).
We recommend using Bio-lubricat-
ing oil or Bio-lubricating grease for
“open”lubricationpointsornipples(as
specified in the operating instruc-
tions).
We recommend using Bio-slushing
oil to preserve machines and attach-
ments (do not apply on painted cov-
ers). You can brush or spray the oil.
Anti-corrosive agents are environ-
mentally friendly and degrade fast.
Usingecologically safe Bio-lubricants
and Bio-anti-corrosives, you contrib-
ute to environmental protection and
to the wellbeing of humans, animals
and plants.
Maintenance and
Repair:
ThetrainedmechanicsofyourAGRIA
workshopexpertlycarryoutanymain-
tenance and repair work.
Youshouldonlycarry out major main-
tenance work and repairs on your
own, if you have the proper tools and
knowledge of machines and internal
combustion engines.
Do not hammer against the flywheel
with a hard object or metal tools as it
might crack and shatter in operation,
causing injuries and damage. Only
use suitable tools to pull off the fly-
wheel.

Fuel Recommendations
Petrol Engine
Robin EH 25 D
This engine runs smoothly on conven-
tional unleaded regular and super-
grade petrol as well as on leaded
supergrade petrol.
Do not add oil to petrol.
If, for environmental reasons, you use
unleaded petrol, make sure the fuel is
drainedcompletely when shuttingdown
the engine for more than 30 days. This
is to prevent resin residue from deposit-
ing in the caburetor, fuel filter, and tank.
Oradda fuel stabilizing liquidtothefuel.
When storing the two-wheel tractor at
theend of the season,also drain leaded
fuel completely or add a fuel stabilizing
liquid.
For further instructions see “Engine
Preservation”.
Diesel Engine
Lombardini 6LD 400
Thisenginerunssmoothlyonconven-
tional diesel fuel or oil seed rape.
Winter operation:
Toensure reliable winteroperation of
the diesel engine use “winter diesel”,
which is sold at filling stations in win-
ter.
At outside temperatures of below
-15° C, additionally, take the follow-
ing precautions:
add conventional flow conditioners
or
add paraffine oil to lower the diesel
pour-point:
Paraffine oil: winter summer
diesel diesel
pour-point
50% ca. -31°C ca. -25°C
30% ca. -26°C ca. -15°C
10% ca. -20°C ca. - 9°C
As a last resort, you can add up to
30% of regular petrol to avoid
paraffine depositing in the machine.
However,this has negative effectson
fuel economy and driving.
