Lubricants and
Anti-Corrosive Agents:
Use the specified lubricants for engine
and gearbox (see “Specifications”).
We recommend using bio-lubricating
oil orbio-lubricating grease for“open”
lubricatingpointsornipples(asspecified
in the operating instructions).
We recommend using bio-slushing oil
forpreservation of machines and imple-
ments (do not apply on painted external
covers). Oil can be brushed or sprayed
on.
Anti-corrosive agents are environmen-
tally friendly 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.
Fuel:
This engine runs smoothly on
commercial unleaded regular and
supergrade 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
drained completely when shutting down
the engine for more than 30 days.This
is to prevent resin residue from deposit-
ing in the caburetor, fuel filter, and tank.
Or add a fuel stabilizer to the fuel.
For further instructions refer to "Engine
Preservation".
Maintenance and
Repair
The trained mechanics of your agria
workshop carry 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
knowledge of machines and internal
combustion engines.
Donot hammeragainst theflywheelwith
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.

3. Devices and Operating Elements
The single wheel cultivator is a
motorised unit for turning over the
ground and may also be used with an
implement.
Thefollowingattachments areavailable:
l Tilling attachment 10–50 cm
l Ridging attachment
l Front weight
l Leaf deflector
Motor
The 4-stroke engine runs on
conventional petrol (see fuel
recommendations of p6).
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 harmful
to any engine and considerably
affects its durability. This applies
especially for no load operation. Any
overspeed (have the engine roar) can
result in immediate damage.
Cooling System
Coolingsystemisfan-cooled.Therefore
keep screen at recoil starter and cool-
ing ribs 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
engineissupposedtorunsmoothlyand
without run-out.
Air Filter
The air filter purifies the air intake. A
clogged filter reduces engine output.
Ignition System
The engine is equipped with a mainte-
nance-free, contactless electronic igni-
tion system. We recommend to have
necessary check-upsdone byan expert
only.
