HOW TO USE YOUR SHREDDER
Do not attempt to shred or chip any material other
than vegetation found in a normal yard (i.e., branches,
leaves, twigs, etc.).
WARNING: The shredder discharges
material with considerable velocity. Keep
away from the area around the chute
deflector. Always stop the engine and dis­
connect the spark plug wire when remov­
ing or attaching the bag, when changing
containers or when removing the shred­
ded material, wear safety glasses and
gloves whenever using your shredder.
1. Leaves and small branches up to 1/2" diameter
can be fed into the hopper when it is in the raised
position. See figure 9. If it becomes necessary to
push material into the shredder, use a small diam­
eter stick—NOT YOUR HANDS. The stick cannot
exceed 1/2" in diameter so it will be ground up if it
gets into the impeller assembly.
WARNING: Do not put material larger than
1/2" in diameter into the hopper. Material
up to a maximum of 3" in diameter materi­
al may be fed into the chipper chute. Do
not attempt to shred or chip any material
larger than 3" in diameter. Personal injury
or damage to the machine could result.
A
Leaves and small twigs can be raked into the
shredder when the leaf ramp is lowered to the
ground. See figure 10. Small branches up to 1/2"
diameter can also be fed into the shredder in this
position. See figure 11.
