Adjusting the blade clearance
The upper/lower blades wear out gradually after operations. If you
cannot get a clean cut though the blades are sharp enough, adjust
the clearance as follows.
The tightness of the hex bolt decides the clearance of the blades.
The nut holds the hex bolt with certain tightness. Too loose clearance
causes blunt cut, but too tight clearance causes unnecessary heat
and sooner worn-out of the blades.
1.
Loosen the nuts with a wrench.
2.
Tighten the hex bolts lightly till they stop. And then, screw them
back a quarter to half turn each to gain necessary clearance.
3.
Hold the hex bolts and tighten the nuts.
4.
Apply light oil on the friction surface of the blades.
5.
Start the motor and operate the throttle on and off for a minute.
6.
Measure the time necessary for the blades to stop after releasing
the throttle. If it is two seconds or longer, switch off the motor and
repeat the step 1 to 6.
7.
Switch off the motor and touch the blade surface. If they are not
too hot to touch, you have made a proper adjustment. If they are too
hot to touch, turn the hex bolts back a little and repeat the step 5 to 7.
