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.
