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

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.

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.

WARNING: Always discon

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

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.

Position the snow thrower on a level

surface.

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.

Loosen the carriage bolts and nuts securing the scraper bar to the au ger housing.

4. Adjust the scraper bar to the proper position.

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.
