English Working Technique Vertical cut Swing the cutting blade from the bottom upwards in an arc - lower the nose of the blade, move along the hedge and then swing the blade up again in an arc. Any working position above head height is tiring. To minimize the risk of accidents, work in such positions for short periods only. 0008BA003 KN Horizontal cut Hold the cutter bar at an angle of 0° to 10° as you swing the hedge trimmer horizontally. Swing the cutting blade in an arc towards the outside of the hedge so that the cuttings are swept to the ground. Repeat the procedure several times on wide hedges. 0008BA005 KN 0008BA004 KN Fuel This engine is certified to operate on unleaded gasoline and with the mix ratio 50:1. Your engine requires a mixture of highquality premium gasoline and highquality two-stroke air-cooled engine oil. Use premium branded unleaded gasoline with a minimum octane rating of 89 RON. Note: Models equipped with a catalytic converter require unleaded gasoline. A few tankfuls of leaded gasoline can reduce the efficiency of the catalytic converter by more than 50%. Fuel with a lower octane rating may result in preignition (causing "pinging") which is accompanied by an increase in engine temperature. This, in turn, increases the risk of the piston seizure and damage to the engine. The chemical composition of the fuel is also important. Some fuel additives not only detrimentally affect elastomers (carburetor diaphragms, oil seals, fuel lines etc.), but magnesium castings as well. This could cause running problems or even damage the engine. For this reason it is essential that you use only high-quality fuels! Fuels with different percentages of ethanol are being offered. Ethanol can affect the running behaviour of the engine and increase the risk of lean seizure. 8 HS 46, HS 46 C, HS 56 C
