OPERATION

BEFORE STARTING ENGINE

Check the oil NOTE: The engine was shipped from the factory filled

with oil. Check the level of the oil. Add oil as needed.

1. Make sure the unit is level.

2. Remove the oil fill cap/dipstick. Check the oil. NOTE: Do not check the level of the oil while the

engine runs.

3. If necessary, add oil until the oil reaches the FULL mark on the oil fill/cap dipstick (see Figure 18). Do not add too much oil.

NOTE: For extreme cold operating conditions of 0°F (-18 ° C) and below, use a synthetic 0W30 motor oil for

easier starting. NOTE: S.A.E. 5W30 motor oil may be used to make

starting easier in areas where the temperature is 20 ° F. (-7 ° C) to 0°F (-18 ° C).

NOTE: SEE CHART FOR OIL RECOMMENDATION

TEMPERATURE TYPE OF OIL

20 ° F. to 0°F

(-7 ° C) to (-18 ° C) S.A.E. 5W30

2. Check to make sure that spark plug istightened securely into engine and spark plug wire isattached to spark plug. If torque wrench is available, torque plug to 18-23 ft_bs.

WARNING: Gasoline is flammable. Always use

caution when handling or storing gasoline. Do

not add gasoline to the fuel tank while snow

blower is running, hot, or when snow blower is in an en- closed area. Keep away from open flame, electrical sparks and DO NOT SMOKE while filling the fuel tank.

Never fill the fuel tank completely; but fill the fuel tank

to within 1/4-1/2 inch (6.5-12.5 mm) from the top to pro- vide space for the expansion of the fuel. Always fill fuel

tank outdoors and use a funnel or spout to prevent spil-

ling. Make sure to wipe up any spilled fuel before start- ing the engine. Store gasoline in a clean, approved container, and keep

the cap in place on the container. Keep gasoline in a

cool well ventilated place; never in the house. Never buy more than a 30 day supply of gasoline to assure

volatility. Gasoline Is intended to be used as a fuel for

internal combustion engines; therefore, do not use gasoline for any other purpose. Since many children

like the smell of gasoline, keep it out of their reach be- cause the fumes are dangerous to inhale, as well as be-

ing explosive.

IN TEMPERATURES ABOVE 0°F (-18°C) Move throttle control to"FAST" position. IN TEMPERATURES BELOW 0°F (-18°C)

Move throttle control to "1/2 THROTTLE" position. Allow engine to idle at "1/2 Throttle" for five minutes to allow en- gine oil to warm before engaging auger drive clutch lever. Failure to allow engine oil to warm can cause damage to

engine.

Insert key into ignition slot. Make sure it snaps into place (Figure 19). Do not turn key.

CHOKE KNOB must be in the off position. Do not use primer button.

Pull starter handle (Figure 19) rapidly, and allow to re- wind slowly while maintaining firm grip on handle.

If engine fails to start after a reasonable number of start- ing attempts, rotate choke knob to the on position and re-

peat instruction number 5.

As engine warms up, move the choke lever to the "1/2 choke" position. When engine does not run smoothly, move choke lever to the off position.

NOTE: Allow the engine to warm up for several minutes before blowing snow in temperatures below O°F (-18 ° C).

Run engine at or near top speed.

To stop engine, move throttle control lever to stop posi- tion. Remove ignition key. Do not turn the ignition key.

To help prevent possible freeze-up of recoil starter and engine controls, proceed as follows after each snow removal

job.

1. With engine running, pull starter rope hard with a continu- ous 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 engine not running, wipe all snow and moisture from carburetor cover in area of control levers. Also move control levers backward and forward several times.

IMPORTANT: After each use of the snow blower, stop the engine, remove the ignition key, remove all accumulated snow from the snow blower and wipe clean. Store the snow blower in a protected area.

OPERATION

OPERATING TIPS

1. For optimum snow blower efficiency, adjust ground speed, not the throttle. REMEMBER - if the wheels slip,

forward speed will be reduced. The engine is designed to deliver optimum performance at full throttle and must

be run at this power setting at all times.

2. Most efficient snowblowing is accomplished when snow is removed immediately after it falls.

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

4. Snow should be discharged downwind whenever pos- sible.

5. For normal usage, set the skids one-eighth inch (3 mm) below the scraper bar. For extremely hard-packed snow

surfaces, the skids may be adjusted upward to insure cleaning efficiency.

6. On gravel or crushed rock surfaces, the skids should be set at 1-1/4 inch (32 mm) below the scraper bar (see To

Adjust Skid Height, in the Adjustment/Repair section in

this manual). Rocks and gravel must not be picked up

and thrown by the machine.

7. After the snowblowing job has been completed, allow the engine to idle for a few minutes, to melt snow and ice ac- cumulated on the engine.

8. Remove ice and snow accumulation from the entire s- now blower to prevent obstructions and possible dam-

age when snow blower is subsequently operated.

9. Before starting snow blower, always inspect augers and impeller for ice accumulation and/or debris, which could result in snow blower damage.

10. Check oil level before every start, fill to "SAFE" indication prior to operating snow blower.

To help avoid possible freeze-up of starter, proceed as follows:

Recoil Starter: With engine running, pull starter rope with a rapid continuous

full arm stroke three (3) or four (4) times. NOTE: The unusual sound made by pulling starter rope

will not harm the engine or the starter. Electric Starter:

1. Connect the "POWER CORD" to the "SWITCH BOX_'and

then to a 120 volt AC receptacle.

2. With engine running, push the "STARTER BUTTON" and spin the starter for several seconds.

NOTE: The unusual sound made by spinning the

starter rope will not harm the engine or the starter.

3. Disconnect the "POWER CORD" from the receptacle

first and then from the "SWITCH BOX".
