General

WARNING! Running an engine in a confined
!
or badly ventilated area can result in death
due to asphyxiation or carbon monoxide
poisoning. Do not use the machine in
enclosed spaces.
Fuel and fuel fumes are flammable and can
cause serious injury when inhaled or
allowed to come in contact with the skin. For
this reason observe caution when handling
fuel and make sure there is adequate
ventilation.
The exhaust fumes from the engine are hot
and may contain sparks which can start a
fire. Never start the machine indoors or near
combustible material!
Do not smoke and do not place any hot
objects in the vicinity of fuel.

Fuel

• Top up with diesel fuel. Gasoline may not be used under
any circumstances.
• Use fuel with a cetane rating over 45. Max RME mixing
5% in mineral oil-based fuels.

Winter fuel

When driving in very cold weather operating problems due to
paraffin precipitation can occur if you run on standard fuel. To
counteract this, winter fuel is sold in the climate areas
affected. In some regions, different fuel is sold in summer and
winter. Ask your fuel supplier and use only winter fuel below
0°C (+32°F).

Fueling

WARNING! Diesel is highly flammable.
!
Exercise care and refuel outdoors.
Clean the area around the fuel cap.
Tighten the fuel cap carefully after refuelling.
If the cap is not properly tightened the cap
might vibrate lose and fuel may escape from
the fuel tank creating a fire hazard.
Move the machine at least 3 m from the
refuelling point before starting it.
The fuel level in the tank is shown by the gauge on top of the
tank.
• Allow the engine to cool before refuelling.
• Check the fuel level before each use and leave space for
the fuel to expand, because the heat from the engine and
the sun may otherwise cause the fuel to expand and
overflow.

FUEL HANDLING

The diesel engine injection system is very sensitive and can
be damaged by the slightest contamination. Observe the
greatest possible fuel cleanliness. Use only clean containers.
• Clean the area around the fuel cap. Contamination in the
tank can cause operating problems.
• When refuelling, open the fuel cap slowly so that any
excess pressure is released gently.
• Wipe up any spillage. Materials contaminated by fuel must
be moved to a safe location.
• Handle oil, oil filters, fuel and the battery carefully, of
environmental considerations. Follow the local recycling
requirements.
Never start the machine:
• If you have spilled fuel on yourself or your clothes, change
your clothes. Wash any part of your body that has come in
contact with fuel. Use soap and water.
• If you have spilled fuel or engine oil on the machine. Wipe
off the spill and allow the remaining fuel to evaporate.
• If the machine is leaking fuel. Check regularly for leaks
from the fuel cap and fuel lines.
• Unless the fuel cap is securely tightened after refueling.

Transport and storage

• Store and transport the machine and fuel so that there is
no risk of any leakage or fumes coming into contact with
sparks or open flames, for example, from electrical
machinery, electric motors, electrical relays/switches or
boilers.
• When storing and transporting fuel always use approved
containers intended for this purpose.
• Store the machine and fuel in such a way that there is no
risk that leaking fuel or fumes can cause any damage.
Fuel which is left to stand for long periods (30 days or more)
can leave sticky deposits and interfere with the engine
function. Fuel stabiliser is an acceptable alternative to avoid
tacky deposits during storage.
• Add stabiliser to the fuel in the tank or the storage
container.
• Always use the mixing ratios indicated by the
manufacturer.
• Run the engine for at least 10 minutes after adding the
stabiliser.
!
WARNING! Never store a machine with fuel
in the tank indoors or in poorly ventilated
spaces where fuel vapour can come in
contact with open flames, sparks, or a pilot
light such as in a boiler, hot water tank,
clothes drier, etc.
Exercise caution when handling fuel. It is
highly inflammable, and careless use can
cause serious injury and damage to
property.
