SAFE OPERATION PRACTICES FOR POWER SHREDDERS
TRAINING
1. The operator should become fully familiar with
all of the different sections of this owner's
manual before attempting to operate this equip¬
ment.
2. Children must never be allowed to operate this
equipment.
3. No one should operate this unit while intoxicated
or while taking medication that impairs the senses
or reactions.
4. This equipment should never be operated in the
vicinity of children, pets or other persons.
5. Never run your machine in an enclosed area as the
exhaust from the engine contains carbon mon¬
oxide, which is an odorless, tasteless and deadly
poisonous gas.
6. Never allow your hands or any part of your body
^ or clothing inside the feeding chamber, discharge
chute, or near any moving part while the machine
or engine is running.
7. If it is necessary for any reason to inspect or repair
the feeding chamber or any part of the machine
where a moving part can come in contact with
your body or clothing, stop the machine, allow it
to cool, and disconnect the spark plug wire from
the spark plug before attempting such inspection
or repair.
•REPARATION
. It is recommended that the operator of this equip¬
ment obtain and wear safety glasses at all times
while operating the machine.
!. Wear proper apparel. Avoid wearing loose fitting
clothing.
I. This machine should be operated only upon an
earthen level surface.
k Assure that all screws, nuts and bolts and other
fasteners are properly secured.
)PERATION
. When feeding shreddable material into this equip¬
ment, be extremely careful that pieces of metal,
rocks, bottles, cans or other foreign objects are
not included.
If the cutting mechanism strikes any foreign ob¬
ject or if your machine should start making an
unusual noise or vibration, immediately stop the
engine and disconnect the spark plug wire from
the spark plug. Allow the machine to stop and
take the following steps:
A. Inspect for damage.
B. Replace or repair any damaged parts.
C. Check for any loose parts and tighten to assure
continued safe operation.
3. The engine must be kept clean of debris and other
accumulations.
4. Do not allow an accumulation of processed mate¬
rial to build up in the discharge area as this will
prevent proper discharge and can result in kick-
back from feed opening.
5. Never allow your hands or any other part of your
body or clothing inside the feeding chamber,
discharge chute or near any moving part while the
engine is running.
6. Keep all guards and deflectors in place and in
good working condition to assure continued safe
operation.
7. Always stand clear of the discharge area when
operating this machine.
8. Keep your face and body back from the feed
opening to avoid accidental bounce back of any
material.
9. Do not over-reach. Keep proper balance and
footing at all times.
10. The engine governor settings on your machine
must not be altered, changed, or tampered with.
The governor controls the maximum safe oper¬
ating speeds and protects the engine and all
moving parts from damage caused by overspeed.
11. Do not transport machine while engine is running.
MAINTENANCE AND STORAGE
1. When this equipment is stopped for servicing,
inspection, storage or to change an accessory,
make sure the spark plug wire is disconnected
from the spark plug. The machine should be
allowed to cool down before making such inspec¬
tion, adjustments, service, etc. Maintain your

FIGURE 12. FEEDING MATERIAL INTO CHIP-IT
GUIDE
Leaves and smaller branches can be fed into the
hopper. See figures 13 and 14.
^^^CAUTION
Do not deposit material larger than
1/2" diameter in hopper. This may
cause damage to the shredding mech¬
anism. Any material heavier than 1/2"
should be fed into the chip-it guide
extension. See figure 12.
It is possible to feed too fast. It will take some
experimenting with feeding rates to get the most
out of your shredder without stalling the engine.
Rotate the material. A steady flow of.material pro¬
vides the best results.
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, a container or the bag.
Your shredder is equipped with a ny¬
lon bag with drawstring lock. This will
accommodate a perforated disposable
plastic bag.
A CAUTION
Keep away from the chute area since
the shredded material comes out with
considerable velocity. Always stop
engine and disconnect spark plug wire
when changing bags.

ADJUSTMENTS
WARNING
If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
CARBURETOR ADJUSTMENTS
Do not make unnecessary adjustment. Factory set¬
tings are correct for most applications. If adjustments
are needed, refer to the engine manual packed with
your shredder.

LUBRICATION
WHEELS - The wheels require no lubrication.
-^ENGINE - Follow engine manual for lubrication
istructions.
MAINTENANCE
A CAUTION
Always stop engine and disconnect
spark plug wire before performing 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 lock nuts (Ref. No. 11). See page 10.
2. Remove bolt (Ref. No. 38), lock washer (Ref. No.
37) flat washer (Ref. No. 36) which holds blade
(Ref. No. 45), and blade retainer (Ref. No. 48)
to engine crankshaft. See page 10.
NOTE
Blade is reversible and can be as¬
sembled to crankshaft with either
side showing.
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
reassembly, make certain all parts are assembled prop¬
erly and tightened securely.
FLAILS AND FINGERS
The flails and fingers can be reversed when they
become dull.
ENGINE OIL
1. Change oil in crankcase after first two (2) hours
of operation. Then change oil every twenty-five
(25) operating hours or sooner if equipment is
operated in extremely dusty or dirty conditions.
Unscrew oil drain plug located on the side at the
bottom of the engine (see figure 15). Always tip
engine towards oil drain hole. Be sure oil drains
completely.
Replace oil drain plug and refill with oil as directed
on page 6.
FIGURE 15
2. Check oil every five (5) operating hours or each
time equipment is used. Add oil as necessary to
keep level full to point of overflowing.
CLEAN ENGINE
Clean cylinder fins and underside of tank or housing
thoroughly of all accumulated grass and debris. This
is an aircooled engine which operates most effeciently
when the cooling fins are clean.
AIR CLEANER
The air cleaner prevents damaging dirt, dust, etc. from
entering the carburetor and being forced into the
engine and is important to engine life and perfor¬
mance.
To service air cleaner, refer to the engine manual
packed with the shredder.
NEVER RUN YOUR ENGINE WITHOUT AIR
CLEANER COMPLETELY ASSEMBLED.
OFF SEASON STORAGE
In event engine is to be stored for any length of time
(30 days or more), prepare as follows:
1. Drain gasoline by tipping or syphone hose, then
run engine until remainder is used and tank and
carburetor are empty.
CAUTION
Drain gasoline into container outdoors,
away from fire or flame.
2. Protect the inside of engine for storage by remov¬
ing spark plug and pouring one ounce of SAE 30
oil through spark plug hole into cylinder. Crank
engine, without starting, several times to spread
oil over cylinder walls.
A CAUTION
When storing any type of power equip¬
ment in an unventilated or metal
storage shed, care should be taken to
rust proof the equipment. Using a
light oil or silicone, coat the equip¬
ment, especially all moving parts.
