Checking/replenishing engine oilWith the engine in a cool state, check/replenish engine oil in•the following way.Position engine on a flat level, and check to see whether oil is•within the range of MAX and MIN of the oil tank.If oil is insufficient (near the MIN mark of the oil tank), fill the•oil tank with oil to the MAX mark.Oil quantity can be checked externally without removing the oil•cap as the oil level can be seen at the external, see-through,measuring mark window.For reference, oil needs to be replenished every ten operating•hours (one tank of oil for ten fuel refuels).Replace extremely dirty or discolored oil.• .... Use API grade SF class or higher SAE10W-30 oil (automobile 4-stroke engineoil). ...............0.22 L (220 mL)NOTE:If the engine is not stored in the upright position, oil will•circulate through the engine, which will mean that there will beexcessive oil in the Power Cutter when replenishing.If oil exceeds the MAX mark, it may leak out causing dirtying•or white smoke.Oil replacement Point 1 Interval of replacement: Initially, after 20 operating hours, andsubsequently every 30 operating hours.Clean away the dirt from around oil filling neck and then•remove oil cap.Place the oil cap on a surface where it will not pick up grit and•dirt. If the cap is put back on in a dirty state, oil circulation maydeteriorate and engine parts become worn, which may causemechanical failure.MAX markMIN markOilThe oil is visible from here, sothe MAX and MIN marks canbe used to check the quantityof oil.
