starter and recoil starter. Before start- ing the engine, be certain that you have

read the following information.

How To Start A Cold Engine

1. Be sure auger drive and traction

drive levers are in the disengaged

(RELEASED) position.

2. Move throttle control to "FAST"

position.

3. Insert the ignition key into the igni-

tion slot. Make sure it snaps into

place. Do not turn key.

4. Rotate choke knob clockwise to the choke ON position.

5. (Electric Start) Plug the power cord into the switch box on the engine. Plug the other end of power cord into a three-hole, grounded 120

VOLT, AC receptacle.

6. Pushthe primer button as speci-

fied below. Remove finger from

primer button between pushes.

• Do not push if temperature above 50 ° F (10 ° C).

• Push two times if temperature is 50° F (10 ° C) to 15°F (-10 ° C).

• Push four times if temperature is

below 15 ° F (-10° C).

• Push five times if temperature is

below 0° F (-18 ° C).

7. (Electric Start) Push down on the starter button until the engine

starts. Do not crank for more than 10 seconds at a time. This electric

starter is thermally protected. If overheated it will stop automatically and can be restarted only when it has cooled to a safe temperature (a

wait of about 5 to 10 minutes is re- quired).

8. (Recoil Start) Rapidly pull the re-

coil starter handle. Do not allow the recoil starter handle to snap

back, Slowly return the recoil start- er handle.

9. If the engine does not start in 5 or 6 tries, See Difficult Starting in the "Troubleshooting Table".

10. When the engine starts, move the choke control to "1/2 choke" posi- tion. When engine runs smoothly,

move choke control to the off Position.

11. (Electric Start) First disconnect

power cord from receptacle. Then, disconnect the power cord from the

switch box.

12. Run engine at full throttle "FAST" when throwing snow.

Allow the engine to warm up for several

minutes before blowing snow in temper- atures below 0°F.

How To Start A Warm Engine

If restarting a warm engine after a short

shutdown, leave the choke lever in the off position and do not push the primer

button. If the engine fails to start, follow

the Cold Start instructions.

FROZEN STARTER

If the 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.

gine exhaust contains CARBON

MONOXIDE, AN ODORLESS AND DEADLY GAS. Keep hands, feet, hair and loose clothing away from

any moving parts on engine and snow thrower,

gine indoors or in enclosed,

poorly ventilated areas. En-

The temperature of muffler and

nearby areas may exceed 150°F.

Avoid these areas.

DO NOT allow children or young

teenagers to operate or be near snow thrower while it is operat-

ing.

TO REMOVE SNOW FROM AUGER

A ARNING: Do not attempt

• auger without taking the following

precautions:

A cleaning stick is attached to the top of the auger housing. Use the cleaning

to remove snow or debris that may become lodged in

stick to remove snow from the auger

housing.

• 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 the

cleaning stick to remove snow.

SNOW THROWING TIPS

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.

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

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

The snow should be discharged

down wind whenever possible.

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.

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.

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.

Clean the snow thrower thoroughly

after each use.

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.
