Lubricants and
Anti-Corrosive Agents
Use the specified lubricants for engine
andtransmission(see“Specifications”).
We recommend using bio-lubricating
oil orbio-lubricating grease for“open”
lubricating points or nipples (as speci-
fied in the operating instructions).
Werecommendusingbioanti-corrosive
oil for preservation of machines and im-
plements (do not apply on painted ex-
ternal covers). Oil can be brushed or
sprayed on.
Anti-corrosive agents are kind to the
environment and degrade fast.
Using ecologically safe bio-lubricants
and bio-anti-corrosives, you contribute
to environmental protection and to the
wellbeing of humans, animals and
plants.
Maintenance and
Repair
The trained mechanics of your agria
workshop carry out expertmaintenance
and repair.
you should only carry out major main-
tenance work and repairs on your own,
if you have the proper tools and knowl-
edge of machines and internal combus-
tion engines.

Petrol Engine
This engine runs perfectly using
commercially available lead-free Nor-
mal and Super petrol (also E10) as
well as Super plus.
Do not add oil to petrol.
If, for environmental reasons, you use
unleaded petrol, make sure the fuel is
drainedcompletelywhenshuttingdown
the engine for more than 30 days.This
is to prevent resin residues from depos-
iting in the carburetor, fuel filter, and
tank. Or add a fuel stabilizer.
For further instructions refer to "Engine
Preservation".
Recommendations Fuel
Diesel Engine
ThisDieselengine runsonconventional
Diesel fuel of a min.cetane rating of 45.
Do not use Diesel fuel oil substitutes,
they may be harmful to the fuel system.
Fuel should be free of water or dust.
Winter operation:
To ensure reliable winter operation use
“winter diesel fuel”, to be purchased at
filling stations.
At outside temperatures of below -
15°C , take the following additional pre-
cautions:
add commercial flow conditioners
or
add paraffine oil to depress diesel pour-
point:

Engine
l The four-stroke petrol engine runs
on commercial petrol (refer to fuel rec-
ommendations page 7).
Ignition System
The engine is equipped with a contact-
less ignition system.We recommend to
have necessary check-ups done by an
expert only.
l The four-stroke diesel engine runs
on commercial diesel fuel (refer to fuel
recommendations p7). See to using
proper fuel in winter.
During the first 20 operating hours
(break-in period) do not use engine to
maximum power.
Even after break-in period never use
engine at higher speed than necessary
for the work in hand.
IHigh engine speed is harm-
ful to any engine and consid-
erably affects its durability. This ap-
plies especiallyfor no load operation.
Any overspeed (have the engine roar)
can result in immediate damage.
Cooling System
Thecooling systemis fan-cooled.There-
fore keep screen at recoil starter and
cooling fins of cylinder clean and free
from sucked-in plant trash.
Idling-speed
Always ensure that idling-speed is ad-
justed correcty.At low speeds and with
the speed control lever set to idle, the
engineissupposedtorun smoothlyand
without run-out.
Air Filter
The air filter purifies the air intake. A
clogged filter reduces engine output.
