SNOW THROWING TIPS

1.For maximum snow thrower efficien­ cy in removing snow, adjust ground speed. Go slower in deep, freezing or wet snow. If the wheels slips, re­ duce forward speed.

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 hardpacked snow surfaces, adjust the skids upward so that the scraper bar touches the ground.

6.On gravel or crushed rock surtaces,

stick to remove snow from the auger housing.

•Release auger drive lever.

•Remove (do not turn) safety key.

•Disconnect spark plug wire.

•Do not place your hands in the au­ ger or discharge chute. Use the cleaning stick to remove snow.

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.

GENERAL RECOMMENDATIONS

The warranty on this snow thrower does not cover items that have been subjected to operator abuse or negligence. To re­ ceive full value from the warranty, the op­ erator must maintain the snow thrower as instructed in this manual.

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

Maintenance, replacement, or repair of the emission control devices and systems can be performed by any non-road engine re­ pair establishment or individual. Regular maintenance will improve the performance

and extend the life of the engine.

WARNING; Do not strike the A flywheel with a hammer or a

hard opject. If done, the fly­ wheel can shatter during operation. Do not tamper with the governor spring, links or other parts to in­ crease engine speed.

AFTER EACH USE

•	Run the machine to clear the auger
	of snow.
•	To prevent freezing of the auger or
	controls, remove all snow and slush
	from the snow thrower.

•Check for any loose or damaged parts.

POWER RATINGS

The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automo­ tive Engineers} code J1940 {Small Engine Power & Torque Rating Proce­ dure) (Revision 2002-05). Given both the wide array of products on which our engines are placed, and the variety of environmental issues applicable to operating the equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a piece of power equipment (actual “on-site” power). This difference is due to a variety of factors including, but not limited to, the following: differ­ ences in altitude, temperature, baro­ metric pressure, humidity, fuel, engine lubrication, maximum governed engine speed, individual engine to engine variability, design of the particular piece of power equipment, the manner in which the engine is operated, engine run-in to reduce friction and clean out of combustion chambers, adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match the values derived using the foregoing codes.

SNOW THROWER

AUGER DRIVE BELT

SERVICE AND ADJUSTMENT

WARNING: Always discon­ A nect the spark plug wire and

place it where it cannot make contact with spark plug to pre­ vent accidental starting when mak­ ing any adjustments or repairs.

TO ADJUST SKID HEIGHT

This snow thrower is equipped with two height adjustment skids, located on the outside of the auger housing. See Figure 20.

These skids elevate the front of the snow thrower.

For normal hard surfaces, such as a paved driveway or walk, adjust the skids as follows.

1.Position the snow thrower on a level surface.

2.Make sure both tires are equally in­ flated. Proper tire pressure is 14 to 17 PSI. See side of tire for maxi­ mum inflation. Do not exceed maxi­ mum sidewall pressure on tire.

3.Place the extra shear bolts supplied with the unit under each end of the scraper bar next to the adjustable skids.

4.Loosen the mounting nuts that hold the adjustable skids. To bring the front of the snow thrower down,

raise the adjustable skids. Tighten the mounting nuts. See Figure 20.

NOTE: For rocky or uneven surfaces, raise the front of the snow thrower by moving the skids down.

WARNING: Be certain to A maintain proper ground

clearance for your particular area to be cleared. Objects such as gravel, rocks or other debris, if struck by the impeller, may be thrown with sufficient force to cause personal injury, property damage or damage to the snow thrower.

TO ADJUST SCRAPER BAR

After considerable use. the metal scrap­ er bar will have a definite wear pattern. The scraper bar in conjunction with the skids should always be adjusted to al­ low 1 /8” between the scraper bar and the sidewalk or area to be cleaned.

1. Position the snow thrower on a level surface.

2. Make sure both tires are equally in­ flated. Proper tire pressure is 14 to 17 PSI. See side of tire for maxi­ mum inflation. Do not exceed maxi­ mum sidewall pressure on tire.

3.Loosen the carriage bolts and nuts

securing the scraper bar to the au­ ger housing.

4.Adjust the scraper bar to the proper position.

5.Tighten the carriage bolts and nuts, making sure that the scraper bar is parallel with the working surface.

For extended operation, the scraper bar may be reversed. If the scraper bar must be replaced due to wear, remove the carriage bolts and nuts and install a new scraper bar.
