Sharpening Or
Replacement
Thefourfree-swinging shreddercutting blades inside
the housing
do
all the shredding. Because
of
the
con-
stant
grinding
action they provide, they're subject
to
wear. To lengthen their lifespan, these blades have
been designed with
four
cutting surfaces (one at each
corner) - only one cutting surface on each blade is
working at any given time. When that edge gets dull,
just rotate the blade so one
of
the three other fresh
edges gets used (see Illustration 5-6). When all
four
edges become dull, it's time
to
replace the
sh
redder flaiI
blade. Directions on
how
to
inspect, then rotate
or
replace, the blades follow.
The chipper blade may also be removed
for
sharpen-
ing,
or
replaced if it is damaged. Instructions follow.
