IMPORTANT

SAFE OPERATION PRACTICES

1. Read the Operating and Service Instruction Manual
carefully. Be thoroughly familiar with the controls

and proper use of equipment.

2. Never allow children to operate a power shredder.

3. Keep the area of operation clear of all persons,

particularly small children and pets.

4. Check fuel before starting engine. Do not fill gas

oline tank indoors, when engine is running, or
while engine is still hot. Wipe off any spilled gas
oline before starting engine.

5. Do not change engine governor settings or over
speed engine.

6. Do not put hands near rotating parts. Keep clear

of discharge opening at all times.

7. If the equipment should start to vibrate abnor
mally, stop the engine (motor) and check imme
diately for the cause. Vibration is generally a
warning of trouble.

8. When cleaning,, repairing or inspecting, make cer
tain blade and all moving parts have stopped. Dis
connect spark plug wire and keep wire away from

plug to prevent accidental starting.

9. Shut engine (motor) off and wait until blade comes

to a complete stop before unclogging chute.

10. Check blade and engine mounting bolts at fre
quent intervals for proper tightness.

11. Keep ail nuts, bolts, and screws tight to be sure
equipment is in safe working condition.

12. Never store equipment with gasoline in the tank
inside of a building where fumes may reach an

open flame or spark. Allow engine to cool before

storing in any enclosure.

13. To reduce fire hazard keep free of grass, leaves or

excessive grease.

USING YOUR SHREDDER

Your shredder is designed for safe, efficient, operation.
CARE, OF COURSE, MUST BE EXERCISED THAT HANDS
ARE KEPT AWAY FROM ALL OPENINGS.
Your shredder guide extension is adjustable. It may be
adjusted to desired height by loosening the hand knob

as shown in figure 1.

FIGURE 1. GUIDE EXTENSION ADJUSTMENT

Feed the material so that it slides down the guide ex

tension. See figure 2.

OPERATION

Service engine with gas and oil. See engine man
ual packed with shredder for complete instruc
tions for the care and maintenance of engine.

READ DIRECTIONS CAREFULLY.

When ready to start engine, place throttle control

lever in START position and start engine in accord
ance with instructions in engine manual. After en
gine starts, move throttle control lever to desired

engine speed. The engine is stopped by placing

control lever in the STOP position.

CAUTION:

The manufacturer recommends that the operator ^

' wear safety glasses or some other suitable eye protec- .

tion as it is possible for chips to be ejected out of the

I inlet openings while feeding material.

FIGURE 2. FEEDING MATERIAL INTO GUIDE

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.

FIGURE 3. FEEDING MATERIAL INTO UPPER GUIDE

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.

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.)
