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.

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 orthe 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".

CUSTOMER RESPONSIBILITIES

Some adjustments will need to be made periodically to properly maintain your snow blower.

Atl adjustments in ADJUSTMENTS/REPAIRS section of this manual should be checked at least once each season.

SNOW BLOWER

The following adjustment should be performed more than once each season.

Auger and Traction Drive Belts should be adjusted after the

first 2 to 4 hours of use, again about mid-season and twice

each season thereafter (See To Adjust Belts paragraph in the Adjustment/Repair section).

AS REQUIRED

Auger Gear Box

The auger gear box is lubricated at the factory and should not require additional lubrication. If for some reason the lubricant should leak out, or if the auger gear box has been serviced, add Lubriplate GR132 Grease or equivalent. Maximum 3-1/4 ounces, (92 grams) should be

used. Remove filler plug D (Figure 22 and Figure 23), once a year.

If grease is visible, do not add. If grease is not visible, use a piece of fine wire, like a dipstick to check if there is grease in the gear box. Mobitux EP1 and Shell Atdania EP1 are suitable equivalents.
