6. Fuel and Lubrication
We recommend that you use apremixed blend of environmentally friendly 2-stroke engine petrol and 2 % oil.
Caution! Petrol is highly flammable. Avoid smoking close to where fuel is handled, do not cause any sparks,
embers or naked flames either. Switch off thebrush cutter/grass trimmer and let it cool before refuelling it.
Refuel outdoors and always move at least 3 metres away from therefuelling site before starting thetrimmer.
Mix petrol (unleaded 95 octane without added ethanol) with agood quality 2-stroke oil intended for air-cooled
2-stroke engines.
Recommended mixture: Petrol/oil 50:1 (2 %).
• The engine is designed to be used with unleaded fuel.
• Use at least an87 octane rated fuel.
• Use unleaded fuel to protect theenvironment and your health.
• Poor quality fuel or oil can damage seals, fuel pipes or thefuel tank.
6.1 Mixing the fuel
N.B. Be precise with themixture.
1. Measure out thepetrol and oil precisely before mixing.
2. Pour asmall amount of thepetrol into aclean fuel can.
3. Pour in all of theoil and agitate thefuel can.
4. Pour in therest of thepetrol and agitate thefuel can for at least aminute. Certain oils do not mix well;
therefore it is important that thefuel can be agitated to mix theoil and petrol. The engine will last longer
if thefuel is well mixed. If thefuel is not mixed properly themixture will be too lean and theengine may
be damaged.
5. Label thefuel can clearly to avoid therisk of misidentification.
6. Fuel containing oil is only intended for 2-stroke engines. Pure petrol is for 4-stroke engines. It is therefore
very important to label fuel containers clearly.
N.B. Do not mix too much fuel; it should be used within one month.
Caution! Only use fuel containing oil for 2-stroke engines, using pure petrol without theaddition of oil will
inevitably cause engine damage which is not covered by theguarantee.
6.2 Filling the fuel tank
1. Unscrew and remove thefuel cap.
2. Fill with fuel until thetank is roughly 80% full.
3. Replace and tighten thefuel cap and wipe up any spilt fuel on or around thegrass trimmer.
Caution!
• Refuel outdoors and on theground.
• Always move at least 3 metres away from therefuelling site before starting thetrimmer.
• Switch off thegrass trimmer and let it cool before refuelling it. Only refuel when you are sure that thefuel
can contains 2-stroke fuel!
5.7 Assembling the shaft
Unscrew thelocking knob (26), hold in therelease
catch (27) and push thebottom half of theshaft into
thetop half of theshaft. Twist thetwo halves until
thecatch locks and then tighten thelocking knob.
