Examine the blade whenever you run out of fuel. If the blade
is damaged or cracked, replace it immediately. If the blade
edge is dull or nicked, have it sharpened or replace it.

in serious personal injury.

very tight. While holding the blade with a block
of wood, put your weight behind the ratchet or
wrench and tighten the bolt securely. This bolt is
very difficult to overtighten.
