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.				19

AUGER DRIVE BELT

Adjust the auger drive belt after the first 2 to 4 hours of use, again about mid- season and twice each season thereaf-

ter (See to "Belt Adjustment" in the

Service and Adjustment section).

CHAIN LUBRICATION

EVERY 25 HOURS

1.Position speed selector lever in first

(1)forward gear.

2.Stand the snow blower up on the auger housing end.

NOTE: When the crank case if filled with oil, do not leave the snow blower standing up on the auger housing for an extended period of time.

3.Remove the bottom panel.

4.Lubricate the chains with a chain type lubricant.

5.For storage, wipe the hexshaft and

sprockets with 5W30 motor oil.

NOTE: Clean all excess grease or oil found on the rubber friction

wheel or the disc drive plate.

CAUTION: Do not allow grease or oil to contact the rubber friction

wheel or the disc drive plate.

6.Install the bottom panel.

AUGER GEAR BOX

The auger gear box is lubricated at the

factory and should not require addition- al lubrication. If for some reason the

lubricant should leak out, have auger gear case checked by a competent re- pairman.
