TWO-STROKE OIL
• Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rat-
ed TCW).
• Never use oil intended for four-stroke engines.

MIXING
• Always mix the petrol and oil in a clean container
intended for fuel.
• Always start by fi lling half the amount of the petrol
to be used. Then add the entire amount of oil. Mix
(shake) the fuel mixture. Add the remaining amount
of petrol.
• Mix (shake) the fuel mixture thoroughly before fi lling
the machine’s fuel tank.
• Do not mix more than one month’s supply of fuel at
a time.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Chain oil
• We recommend the use of special oil (chain oil) with
good adhesion characteristics.
• Never use waste oil. This results in damage to the oil
pump, the bar and the chain.
• It is important to use oil of the right grade (suitable
viscosity range) to suit the air temperature.
• In temperatures below 0°C (32°F) some oils become
too viscous. This can overload the oil pump and re-
sult in damage to the oil pump components.
• Contact your service agent when choosing chain oil.
FUELLING
WARNING! Taking the following precautions,
will lessen the risk of
fi re: Do not smoke and
do not place any hot objects in the vicinity of
fuel. Always stop the engine and let it cool for a few
minutes before refuelling. When refuelling, open the
fuel cap slowly so that any excess pressure is released
gently. Tighten the fuel cap carefully after refuelling.
Always move the machine away from the refuelling
area before starting.
ASSEMBLY
FITTING THE BAR AND CHAIN
WARNING! Switch off the engine before car-
rying out any checks or maintenance. The
stop switch automatically returns to the start
position. In order to prevent unintentional starting, the
spark plug cap must be removed from the spark plug
when assembling, checking and/or performing mainte-
nance.
Always wear gloves, when working with the chain, in
order to protect your hands from injury.
Check that the chain brake is in disengaged position by
moving the front hand guard towards the front handle.
Remove the bar nuts and remove the clutch cover
(chain brake). Take off the transportation ring.
Fit the bar over the bar bolts. Place the bar in its rear-
most position. Place the chain over the drive sprocket
locate it in the groove on the bar. Begin on the top edge
of the bar.
Make sure that the edges of the cutting links are facing
forward on the top edge of the bar.
Fit the clutch cover (the chain brake) and locate the
chain adjuster pin in the hole in the bar. Check that
the drive links of the chain
fi t correctly over the drive
sprocket and that the chain is correctly located in the
groove in the bar. Tighten the bar nuts
fi nger tight.
Tension the chain by turning the chain tensioning screw
clockwise using the combination spanner. The chain
should be tensioned until it does not sag from the un-
derside of the bar.
The chain is correctly tensioned when it does not sag
from the underside of the bar, but can still be turned
easily by hand. Hold up the bar tip and tighten the bar
nuts with the combination spanner.
When
fi tting a new chain, the chain tension has to be
checked frequently until the chain is run-in. Check the
chain tension regularly. A correctly tensioned chain en-
sures good cutting performance and long life.
FUEL
Note! The machine is equipped with a two-stroke en-
gine and must always be run using a mixture of petrol
and twostroke oil. It is important to accurately measure
the amount of oil to be mixed to ensure that the cor-
rect mixture is obtained. When mixing small amounts
of fuel, even small inaccuracies can drastically affect
the ratio of the mixture.
WARNING! Always ensure there is adequate
ventilation when handling fuel.
Petrol
• Use good quality unleaded or leaded petrol.
• The lowest recommended octane grade is 92.
• When working with continuous high revs (e.g. limb-
ing) a higher octane is recommended.
Running-in
Avoid running at a too high speed for extended periods
during the
fi rst 10 hours.
