EXTENSION
A steady flow of material provides the best results.
Bulky material, such as stalks or heavy branches, should
be fed into the upper guide extension. See figure 3.
When sharpening blade, follow the original angle of
grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade
will cause excessive vibration when rotating at high
speeds and may cause damage to the unit. Upon reas­
sembly, make certain all parts are assembled properly
and tightened securely.

EXTENSION
It is possible to feed too fast and you will find it will
take some experimenting with feeding rates to get
the most out of your shredder without stalling the en­
gine.
Under certain conditions, it may be necessary to push
the materials into the inlet guide assembly. When this
becomes necessary, use a small diameter stick—NOT
YOUR HANDS. The stick should be of a size that will be
ground up if it gets into the impeller assembly.
The discharge chute will direct the shredded material
into a pile or a container. NOTE: Your shredder is
equipped with a nylon bag with drawstring lock. This
will accommodate a perforated disposable plastic bag.
CAUTION: Keep clear of the chute area since the
shredded material comes out with considerable velo­
city. Always stop engine and disconnect spark plug
wire when changing bags.
MAINTENANCE
CAUTION: Always stop engine and disconnect spark
plug wire before doing any maintenance.
Cutting Blade— The blade may easily be removed for
grinding or replacement as follows:
1. Remove guide extension assembly by removing
four elastic locknuts. See figure 3.
2. Remove bolt (Ref. No. 54), lockwasher (Ref. No.
55) and flat washer (Ref. No. 20) holding blade
(Ref No. 56) to engine crankshaft. See figure 4.
3. NOTE: Blade is reversible and can be assembled
to crankshaft with either side showing.
LUBRICATION
WHEELS—Wheel bearings are of lifetime Fortiflex. They
require no lubrication.
ENGINE—Follow engine manual for lubrication instruc­
tions.
CAUTION
Do Not deposit material larger
than Vi" diameter in hopper.
This may cause damage to the
shredding mechanism.
BEFORE STARTING
NOTE
Do not mix oil with gasoline.
1. Fill fuel tank with fresh regular gasoline. (See fig­
ure 4.)
2. Fill crankcase with oil. (See figure 4.)
