FILL GAS:

The engine is certified to comply with California and US EPA emission regula-

tions for ULGE (Utility or Lawn and Gar- den Equipment) engines. ULGE

engines are certified to operate on reg- ular unleaded gasoline.

_ ARNING: Alcohol blended

fuels (called gasohol or

those using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel sys- tem of an engine while in storage.

NOTE: To avoid engine problems, the

fuel system must be emptied before storage for 30 days or longer. Start the engine and let it run until the fuel lines

and carburetor are empty. Use fresh fuel next season. See the Storage

FROZEN STARTER

Ifthe starter is frozen and will not turn

engine:

1. Pull as much rope out of the starter as possible.

2. Release the starter handle and let it snap back against the starter. Re-

peat until the engine starts.

To help prevent possible freeze-up of recoil starter and engine controls, pro-

ceed as follows after each snow remov- al job.

1. With the engine running, pull the starter rope hard with a continuous

full arm stroke three or four times.

Pulling of starter rope will produce a loud clattering sound. This is not harmful to the engine or starter.

2. With the engine not running, wipe all snow and moisture from the carbu-

retor cover in area of control levers.

Also move throttle control, choke

control, and starter handle several

times.

HOW TO REMOVE OBJECTS FROM AUGER

_ ARNING: Do not attempt

without taking the following precau- tions:

to remove any item that may become lodged in auger

• Release auger drive lever.

• Move throttle lever to stop position.

• Remove (do not turn) ignition key.

• Disconnect spark plug wire.

• Do not place your hands in the au- ger or discharge chute. Use a pry

bar.

SNOW THROWING TIPS

1. For maximum snow thrower efficien- cy in removing snow, adjust ground

speed, NEVER the throttle. Go slower in deep, freezing or wet snow. If the wheels slips, reduce forward speed. The engine is de- signed to deliver maximum perfor-

mance at full throttle and should be run at this power setting at all times.

2. Most efficient snow throwing is ac- complished when the snow is re- moved immediately after if falls.

3. For complete snow removal, slightly overlap each path previously taken.

4. The snow should be discharged down wind whenever possible.

5. For normal usage, set the skids so that the scraper bar is 1/8" above the skids. For extremely hard- packed snow surfaces, adjust the

skids upward so that the scraper bar touches the ground.

6. On gravel or crushed rock surfaces, set the skids at 1-1/4" below the

scraper bar. See To Adjust Skid Height paragraph in the Service &

Adjustments section of this manu-

al. Rocks and gravel must not be picked up and thrown by the ma-

chine.

7. After the snow throwing job has been completed, allow the engine to

idle for a few minutes, which will melt snow and accumulated ice off

the engine.

8. Clean the snow thrower thoroughly after each use.

9. Remove ice and snow accumulation and all debris from the entire snow

thrower, and flush with water (if pos-

sible) to remove all salt or other chemicals. Wipe snow thrower dry.

GENERAL RECOMMENDATIONS The warranty on this snow thrower

does not cover items that have been subjected to operator abuse or negli- gence. To receive full value from the

warranty, the operator must maintain the snow thrower as instructed in this

manual. Some adjustments will need to be

made periodically to properly maintain your snow thrower.
