OPERATION

WARNING: Be sure to read the fuel information in the safety rules before you be- gin. If you do not understand the safety rules, do not attempt to fuel your unit. Contact an authorized service dealer.

FUELING ENGINE

WARNING: Remove fuel cap slowly when refueling.

This engine is certified to operate on unleaded petrol. Before operation, petrol must be mixed with a good quality 2-cycle air-cooled engine oil. We recommend McCulloch brand oil mixed at a ratio of 40:1 (2.5%). A 40:1 ratio is obtained by

mixing 5 liters of unleaded petrol with 0,125 liter of oil. DO NOT USE automotive oil or boat oil. These oils will cause engine damage. When mixing fuel, follow instructions printed on oil con- tainer. Once oil is added to petrol, shake con- tainer momentarily to assure that the fuel is thor- oughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit.

IMPORTANT

Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic petrol can damage the fuel system of an engine while in storage. To avoid engine problems,
