To Install Blades:
The upper and lower blades are inter­
changeable. When fastening the blade mount­
ing screws, torque them uniformly (Torque: 100
to 130 in-lbs)
To Sharpen Blade:
1 . When the corners of cutter become
rounded and the cutting edges become
dull, resharpen using a small disk grinder,
etc.
Do not round the corners.
2. When sharpening, offset the top and bot­
tom blade teeth by 1/8 inches, as shown in
the illustration.

Resharpen these 3 surfaces
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 re­
peated use and resharpening. Replace
with a new blade when the width at the
end becomes less than 5/16 in.

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:
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.
