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.
UrPER nUIDL I «IFNSI JN
ELASTIC LOCK NUT
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.)
Fill with regular gasoline
Shorting Clip
Oil Dip Stick
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.
Drain Plug

Drain Plug
FIGURE 4.
PosiHon equipment so that engine is setting level.
Remove dip stick or oil filler plug (Figure 1). Pour
oil into oil filler tube from which dip stick was re
moved and fill to FULL mark on dip stick. Do not over
fill. After initial filling follow instructions on dip stick.
Be sure dip stick is screwed into filler opening as far
as it will go when measuring oil level.
During initial break-in period, oil level should be
watched closely See ENGINE MAINTENANCE.
Use MS classification oil. Do not use oils marked only
MM or ML or unmarked.
Above 32° use SAE 30; below 32° use SAE lOW These
recommendations must be followed for best perform
ance and long life.
Change oil first two (2) hours of operation and check
oil level every five (5) operating hours or each time
equipment is used.
Change oil every twenty-five (25) operating hours or
sooner if equipment is operated in extremely dusty or
dirty conditions.
TO STOP ENGINE
1. Press shorting clip against end of spark plug (fig
ure 4) and hold until engine stops running. If short
ing clip is not present move carburetor control to
STOP position, if key starting is used, turn key to
OFF position.
2. Turn off gasoline shutoff valve at underside of tank,
if engine is so equipped. Some engines may have
two valves, one at each end of tank.
3. Remove high tension wire from spark plug to pre
vent accidental slating by children while equip
ment is unattended.
ENGINE MAINTENANCE
To obtain long life and trouble-free service from
your engine, certain normal maintenance must be per
formed as outlined below:
NOTE: Carburetors are preset at the factory. DO NOT
attempt to make adjustments at this time. See carbu
retor instructions outlined under CARBURETOR AD
JUSTMENT.
NOTE: If engine is equipped wth 6:1 gear reduction

WARRANTY PARTS AND SERVICE POLICY
The purpose of warranty is to protect the customer from defects in material and workmanship, defects
which are not detected at the time of manufacture.
Our aim is to build into our product quality and reliability. Considerable emphasis is placed on quality
control in order to assure our customer of satisfactory product performance. To achieve this goal, it is
necessary to gain the cooperation of all concerned, MTD, our sales force and our customers.
MTD's responsibility is to build a quality product and to back up that product. MTD must build this
quality product at a competitive price. This cannot be achieved without production in quantity. Quantity
production is mass production. In mass production it is always possible for undetected defects to be
present when the product reaches the customer. Our warranty is extended to assure the customer that
any such defects will be corrected.
Use and maintenance are the responsibility of the customer. MTD cannot assume responsibility for con
ditions over which it has no control. MTD's responsibility does not cover misuse, excessive use, accident
neglect, improper maintenance or alterations by unauthorized persons. Satisfactory product performance
can only result when a manufacturer provides and backs up a quality product and the customer follows
through with proper use and proper maintenance of that product. When both the manufacturer and the
customer recognizes and assumes his responsibility, satisfactory product performance and customer sat-
isfactjon ere assured.
