Tightening the V-belt / Checking V-belt tension IMPORTANT: Exact V-belt tension is essential for maximum cutting performance with minimum fuel consumption. Improper V-belt tension will result in premature wear to the V-belt and V-belt wheel or damage to the clutch bearing. NOTE: The two hex. nut (9) must be loosened before tightening the V-belt or checking the tension. To increase the belt tension, turn the tension screw (10) to the right (clockwise) with the combination wrench included with the 11 Power Cutter. The belt tension is correctly adjusted when the nut (11) is located as shown in the figure compared to the position of the mark (12). IMPORTANT: • After tightening/inspection, make certain to tighten the hex. nut (9) (25 - 31 Nm). • Do not adjust the belt tension while the machine is hot. There is a risk of burn injury. Before operating 1. Checking/replenishing engine oil • With 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 SAE 10W-30 oil (automobile 4-stroke engine oil).
