D.FUELMIX

Use only fuel recommended by this manual.

This product is fitted with a 2-stroke engine and therefore requires a 2-stroke petrol and oil mix. Use leaded (4 Star) or unleaded petrol with a minimum octane rating of 90.

Only use oil from sealed containers. In order to obtain a good fuel mix, put the oil into the container before the petrol.

The use of sub-standard petrol or oil may reduce performance or reduce the life of certain components.

Leaded Petrol

If using leaded petrol, the correct fuel mix is achieved by either using 5% (20:1) of a well known brand of 2-stroke engine oil, or else 2.5% (40:1) of special engine oil.

Unleaded Petrol

If using unleaded petrol, you must use a totally synthetic 2-stroke engine oil or branded 2-stroke engine oil. In either case use 2.5% (40:1) of oil.

IMPORTANT

Always shake the fuel mix container thoroughly before pouring any fuel mix.

Fuel mix properties may deteriorate with time and should be used up within 2 months.

We recommend that you prepare fuel mix according

to your immediate requirements only. Never use fuel mix more than 2 months old so as to avoid possible engine damage.

WARNING

Do not smoke when re-fuelling.

Always open the fuel cap slowly, to release any pressure build up in the tank.

Re-fuel in open spaces only, keeping away from naked flames or sparks.

Safe Storage of Fuel

Petrol fuel mix is highly inflammable. Put out all cigarettes, pipes and cigars before working with fuel. Avoid spilling fuel.

Store fuel in a cool, well ventilated place, in an approved container specifically designed for the purpose. Never store engine with fuel in the tank in enclosed, poorly ventilated areas, where fuel fumes may reach an open flame, spark or pilot light such as in a furnace, water heater, clothes dryer etc.

Petrol fumes can cause an explosion or a fire. Never store large amounts of fuel.

To prevent possible restarting problems avoid running the fuel tank dry. This also helps to extend engine life.
