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 incontact 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 rep_iir.

PREPARATION

1. Wear safety glasses provided with your unit

while operating the chipper-shredderto prevent in-

jury from any chips which may be ejected outof

the openings.

2. Wear proper apparel. Avoid wearing loose fitting

clothing, Wear gloves when handling material,

3. HANDLE FUEL WITH CARE as gasoline is an

extremely flammable fuel,

A. Check the fuel before starting the engin_ Do

not fill the fuel tank indoors, while the engine

is running, or while the engine is still hot. Turn

the unit off and let the engine cool before

refueling.

B. Fuel your chipper-shredder in a clean area. Do

not smoke while refueling.

.... C. Fuel tank cap must be secure at all times

.... except during refueling.

D. Avoid spillir_ggasoline or oil. Wipe the unit

clean of any spilled fuel or oil.

E. Store fuel and oil in approvedcontainers, away

.: from,heat or open flame, and out of reach of

children.

4. This machine should be operated only upon a

level earthen surface.

5. Assure that all screws, nuts and bolts and other

_fasteners are property secured.

=OPERATION

'i. _=When feeding shreddable material into this equip-

ment, be extemely careful that pieces of metal,

4. Do not allow an accumulationof processedmaterial

to build up in the discharge area as this will pre-

vent 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 _s 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 machin_

8. Keep your face and body back from the feed

opening to avoid accidentatbounce 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 governorcontrolsthe maximum safe operating

speeds and protects theengine and all moving

parts from damage caused by overspeed.

11. Do not transport machine while engine is running.

12. Do not operate=engine if air Cleaner or cover

directly over carburetor air it_take is removes,

except for adjustment. Removal of such parts

could create afire hazard.

MAINTENANCE AND STORAGE

1. When this equipment is stopped for servicing,

inspection, storage or to change an accessory,

make surethe sparkplug wire is disc0nnectedfrom

the spark plug. The machine should be allowed to

cool down before making such inspection, ad-

justments, service, etc Maintain your machine with

•OFF'SEASON STORAGE

It is important to prevent gun deposits from forming

in essential fuel system parts such as the carburetor,

fuel hose or fuel tank during storage. Also, experience

indicates that alcohol blended fuels (called gasohol or

using-ethanol or methanol} can attract moisture which

.lead_, to separation and formation of acids during

storage. Acidic gas can damage the fuel system'ofan

engine while in storage.

_To avoid engine problems, the fuel system should .be

"emptied before storage of 30 days or !onger. Follow

these instructions.

1. Drain the fuel tank. Start the engine, and let it run

Until the fuel lines and carburetor are empty.
