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).
Werecommend usingbio anti-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
workshopcarry outexpert maintenance
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.
Donothammer againsttheflywheelwith
a hard object or metal tools as it might
crack and shatter in operation causing
injuries and damage.Only use suitable
tools for pulling the flywheel.

Engine
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 50 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 especially for no load operation.
Anyoverspeed (have the engine roar)
can result in immediate damage.
Cooling System
Thecoolingsystem isfan-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
engineis supposedto runsmoothlyand
without run-out.
Air Filter
The air filter purifies the air intake. A
clogged filter reduces engine output.

the lever will automatically go to STOP position!
Solenoid valve for fuel supply
(at the left side of the engine in front of the air cleaner)
the engine stops by the electrical command of the safety
circuit or starter lock in position 0, if the lever at the sole-
noid valve is at position ! The lever position is
leaded and has to be leaded again if there is any repair.
WThe lever position at the solenoid valve may
not be used for operation, because no electrical
disconnection takes place and also the safety circuit
