8. Maintenance

To Sharpen Blade:

1. When the corners of cutter become rounded and

the cutting edges become dull, resharpen using

a small disk grinder, etc. (MA2)

2. When sharpening, offset the top and bottom

blade teeth by 1/8 inches (3.125mm), as shown

in the illustration. (MA3)

(1) Offset

(2) Top blade

(3) Bottom blade

Apply the grinder lightly and quickly. Pressing too

strongly or grinding for too long will generate heat

which can soften the temper of the blade and

accelerate wear.

3. The width of cutter decreases with repeated use

and resharpening. Replace with a new blade

when the width at the end becomes less than

5/16 in (7.75mm). (MA4)

(1) New blade

(2) Worn out blade

Using a worn blade can cause chipping of cutters,

resulting in a loss of operation time and shorter

service life of the machine.

To Rotate Blade By Hand: (MA5)

When resharpening an old blade or replacing with

a new blade, insert the accessory hex wrench into

the hex hole in the top of the crankcase and turn

strongly 2~3 times. This removes burrs and uneven

painting from the blade and makes starting easier.

(1) Turn

(2) Hex wrench

Never perform this operation while the engine

is running because this is extremely

dangerous. Always stop the engine before

inspecting the blade for any reason.
