Sharpening the blade

If the cutting blades have become blunt and cutting performance is poor, have the
blades sharpened by an authorized service agentέ
Adjusting blade clearance
The upperήlower blades wearέ If you cannot get a clean cut though the blades are sharp enough, adjust the clearance as followsέ
The tightness of the truss bolt decides the clearance of the bladesέ The nut holds the truss bolt with certain tightnessέ Too loose clearance
causes blunt cut, but too tight clearance causes unnecessary heat and sooner wornάout of the bladesέ
1έ δoosen the nut (1) with a box or openάended wrenchέ
βέ Tighten the truss bolt (β) with a hex wrench lightly till it stopsέ And then, screw it back between a quarter turn and a half turn to gain
necessary clearance.

4έ Apply light oil on the friction surface of the bladesέ
ηέ Start the engine, operate the throttle on and off for a minuteέ
θέ Stop the engine and touch the surfaceέ If they are not too hot to touch, you have made a proper adjustmentέ If they are too hot to touch, turn
the truss bolt (β) back a little and repeat the step η to θέ
στTEμ Before making the adjustment, stop the engine and wait for the blades to stopέ
