10. Check that the chain can be

 

smoothly pulled around the

 

guide bar by hand and that

����

it maintains contact with the

�����

guide bar, top and bottom.

�����

To check tension, rotate the

 

chain to its tightest condition

 

then suspend a 0.9kg weight from the chain at the mid point of the underside of the bar. The maximum distance between the driving links and the bar should be 6.5mm.

Note. Ensure the engine is switched off when making any adjustments to the chain and bar.

CAUTION. A new chain will stretch after just a few minutes of use. Check and, if necessary, re-adjust the chain tension. A loose chain causes rapid wear to both the chain and the guide bar and could derail causing a major safety hazard.

Filling up with fuel and oil

WARNINGS. Petrol is very flammable. Avoid smoking or causing any sparks or flames near fuel. Make sure that you stop the motor and allow it to cool before refuelling the machine. Select outdoor bare ground for fuelling and move at least 3m away from the fuelling point before starting the motor.

•Only use oil that is expressly labelled for use with air- cooled 2-stroke engines. DO NOT use BIA or TCW (2-stroke water-cooling type) mixed oil.

The recommended mixing ratio is PETROL 35: OIL 1

•Use unleaded petrol with a minimum Octane number of

89. If you use petrol with an Octane number lower than 89, there is a danger that the engine might overheat and the piston seize.

•Poor quality petrol or oil may damage sealing rings, fuel lines or the fuel tank. Do not use wasted or regenerated oil, it can damage the oil pump.

CAUTION. To maximise the lifetime of the engine, avoid the following:

•Do not use raw petrol, it will severely damage the engine very quickly.

•Do not run the tank dry, as this will cause damage to the engine.

•Do not use oil meant for 4-stroke engines, it will cause spark plug fouling, exhaust blocking and piston ring sticking.

•Do not use fuel mixtures that have been left standing for one month or more, they can cause clogging of the carburettor.

Before storing the chainsaw for an extended period, empty the fuel tank, clean it then run the motor to empty the carburettor.

Note. Do not discard an unwanted fuel container with household waste. It must be taken to an authorised repository site.

Mixing fuel (35:1 mixing ratio)

1.Measure out the quantities of petrol and oil to be mixed.

2.Put some of the petrol into a clean, approved fuel container.

3.Pour in all of the oil and mix well.

4.Pour in the rest of the petrol and again mix well (at least one minute).

5.It is very important to mix the two ingredients properly to prevent unnecessary engine wear.

6.Make sure that the container is clearly labelled that it is 2-stroke mixture.

Fuelling the chainsaw

1.The engine must be stopped and cool. Place the chainsaw on its side with the fuel tank cap facing upwards.

2.Make sure that the fuel mixture is well mixed.

3.Remove the fuel tank cap (23).

4.Fill the fuel tank to about 80% of its capacity.

5.Fasten the fuel cap securely and wipe up any fuel spillage around the machine.
