OPERATION

TO USE WEIGHT TRANSFER SYSTEM ...................... ..............................

In hard packed or heavy snow conditions, conventional

snow throwers tend to ride up and leave uneven mounds

of snow behind. For these conditions, your new tracked

snow thrower has a unique weight transfer system (See

Fig, 11) designed to minimize ride-up,

Stepping on the weight transfer pedal shiit s more weight

to the auger housing. This weight transfer keeps the

snow thrower in contact with the ground and reduces

ride-up.

In Iighter snow conditions or when transporting, you

should release the weight transfer system 1or easier

steering.

e To use the weight transfer, hold the upper handle

firmly and push down on the weight transfer pedal

(See Fig_ 12) with the ball of your foot.

e To release, pull up on the weight transfer pedal with

the top of your foot.

BEFORE STARTING THE ENGtNE

FILL! ADD OIL:

The engine on this snow thrower was shipped without

oil, Add oil before you start the engine.. Remove the oil

fill cap/dipstick and fill the crank case to FULL line on

dipstick (about 21 ounces) (See Fig.. 13) with S.AE.

10 W-30 motor oil (or equivalent). Do not overfill. Tighten

the fill cap/dipstick securely each time you check the oil

level,,

NOTE: SAE. 5W-30 motor oil may be used to make

starting easier in areas where temperature is consis-

tently 20° F, or lower..

FILL GAS:

Fill the fuel tank with clean, fresh, unleaded grade auto-

motive gasoline., Be sure that the container you pour the

gasoline from is clean and free from rust or other foreign

particles.. Never use gasoline that may be stale from long

periods of storage in the container°

WARNING: Experience indicates that alcohol blended

fuels (called gasohol or' using ethanol or methanol) can

attract moisture which leads to separation and formation

of acids during storage.. Acidic gas can damage the fuel

system of an engine while in storage,

To avoid engine problems, the fuel system should be

TO STOP ENGmNE

eTo stop engine, move the throttle control lever to

"STOP" position and remove key. Keep the key in a

safe place_ The engine will not start without the key.

TO START ENGINE

Be sure that the engine has sufficient oil. Before starting

the engine, be certain that you have read the following

information:

COLD START (See Fig. 14)

OBe sure the auger and the traction clutch levers are

in the disengaged "RELEASED" position.

®Move the throttle control up to "FAST" position.

®Push the key into the ignition slot. Be sure it snaps

into place, Do not turn key.

o

o

o

Rotate choke control to "FULL" choke position,

Press the primer button two or three times, while

keeping your finger' over the vent hole on the primer

button. Additional priming may be necessary for the

first start if the temperature is below 15° F,

Pull the starter handle rapidly, Do not allow the

handle to snap back, but allow it to rewind slowly

while keeping a firm hold on the starter handle.

As the engine warms up and begins to operate

evenly, rotate the choke knob slowly to "OFF" posi-

tion. If the engine falters, return to "FULL" choke,

then slowly move to "OFF" choke position.

NOTE: Allow the engine to warm up for a few minutes

because the engine will not develop full power until it

reaches operating ternperature.

eRun the engine at or near the top speed when

throwing snow..

FROZEN STARTER

tf the starter is frozen and will not turn engine:

oPutl as much rope out of the starter as possible.

eRelease the starter handle and let it snap back

against the starter_

If the engine still fails to start, repeat unlit it starts..

To help prevent possible freeze-up of recoil starter and

engine controls, proceed as follows after each snow

removal job,.

o With the engine running, putl 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 harmlu! to the engine or starter

eWith the engine not running, wipe all snow and

moistu refrom the carburetor cover in area of control

levers_ Also move throttle control, choke control,

and starter handle several times.

SNOW THROWING TIPS

o For maximum snow thrower efficiency, adjust ground

speed, not throttle. Ifthe track slips, reduce forward

speed_ The engine isdesigned to deliver maximum

performance at full throttle and shou{d be run at this

power setting at all times..

•Most efficient snow blowing is accomplished when

the snow is removed immediately after it falls

eFor complete snow removal, slightly overlap each

path previously taken.

eThe snow should be discharged down wind when-

ever possible..

o

o

For normal usage, set the skids so that the scraper

bar is 1/8" above the skids. For extremefy 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 Skids Height Ad-

justment paragraph on page 16). Rocks and gravel

must not be picked up and thrown by the machine..

If the front of the snow thrower has a tendency to

raise, reduce the ground speed and engage the

weight transfer system.

After the snow blowing iob 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 {ce and snow accumulation and all debris

from the entire snow thrower, and flush with water (it

possible) to remove all salt orotherchemicals. Wipe

snow thrower dr_'_
