Recommendations
Maintenance and
Repair
The trained mechanics of your agria
workshopcarryout expert maintenance
and repair.
You should only carry out major
maintenance work and repairs on your
own, if you have the proper tools and
knowledge of machines and internal
combustion engines.
Donothammer against 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.
Fuel
Petrol Engine
This petrol engine runs smoothly on
commercial unleaded regular 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 residues from
depositing in the carburetor, fuel filter,
and tank. Or add a fuel stabilizer.
For further instructions refer to „Engine
Preservation“.
Diesel Engine
ThisDieselengineruns on conventional
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:
Paraffine winter summer
oil: diesel diesel
fuel fuel
pour-point
50% app.-31°C app.-25°C
30% app.-26°C app.-15°C
10% app.-20°C app.- 9°C
As a last resort,youcanaddup to 30%
of regular petrol to avoid paraffine de-
posits.However, this has negative ef-
fects on consumption rate and perfor-
mance.

Theride-onbrushcutteragriaSitting Bull
is suited for use in farming and forestry
as well as grass maintenance, such as
for example the mowing of grass and
meadows.
Engine
l The four-stroke petrol engine runs
on commercial unleaded petrol (refer to
fuel recommendations page 6).
Ignition System
The engine is equipped with a
contactless 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
recommendationsp6).Seeto using pro-
per 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
applies especially for no load
operation. Any overspeed (have the
engine roar) can result in immediate
damage.
Cooling System
The cooling system is fan-cooled.
Therefore 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
adjusted correctly.At low speeds and
with the speed control lever set to idle,
the engine is supposed to run smoothly
and without run-out.
Air Filter
The air filter purifies the air intake. A
clogged filter reduces engine output.
