Carefully examine the accelerator for excessive wear
(Figure 25). Because sand and abrasive material can
wear away the metal (especially in the area shown
as item 2 in Figure 25), check the accelerator before
using the machine. If you notice that a tab on the
accelerator has been worn down to a sharp edge or
there is a crack, replace the accelerator.

thickly padded glove.
2. Remove the blade bolt, the lock washer, the
accelerator, and the blade
Sharpening the Blade
Service Interval: Every 50 hours—Sharpen or
replace the blade. Maintain it more
frequently if the edge dulls quickly in
rough or in sandy conditions.
File the top side of the blade to maintain its original
cutting angle (Figure
radius (Figure 26B). The blade will remain balanced if
you remove the same amount of material from both
cutting edges.
1. Sharpen the blade at this
angle only.
Balancing the Blade
1. Check the balance of the blade by placing
the center hole of the blade over a nail or
screwdriver shank clamped horizontally in a vise
(Figure 27).
Note:
You can also check the balance using a
commercially manufactured blade balancer.
2. If either end of the blade rotates downward, file
that end (not the cutting edge or the end near
the cutting edge) until neither end of the blade
drops.
