FUEL MIXTURE

Refer to the values in Figure 9.

Use a 2% (50:1) oil/gasoline mixture.

Two-stroke engines have high specific horsepower and we therefore recommend the use of well- known, super gasoline, without lead and an octane rating of no less than 90. When preparing the mixture, only use a high quality oil designed for air- cooled two stroke engines. Shake the fuel canister before filling. Refill (Fig. 10) when the engine is switched off and far away from an open flame. Before unscrewing the fuel tank cap, position the chain saw on a flat, solid surface to prevent fuel spills. Only prepare the quantity of mixture for each job, do not leave the mixture in the fuel tank or in a fuel canister for prolonged periods.

CHAIN LUBRICATING OIL

Proper chain lubrication during the cutting phase will reduces wear to a minimum between the chain and bar. Correctly lubricating the chain will prolonging the chain saw’s life. Always use a good quality oil (Fig. 11). Refill the oil reservoir each time you refill the unit with fuel.

Never use waste oil. Always use biodegradable lubricant (part number em-1108014) which is specific for bar and chain and also respectful towards nature and the chain saw's parts.
