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
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 "Belt Adjustment" in the
Service and Adjustment section).
AUGER SHAFT LUBRICATION
EVERY 8 HOURS
1. Lubricate the Zerk fittings (A) every ten
hours with a grease gun.
2. Each time a shear bolt is replaced,
the auger shaft MUST be greased.
See Figure 25. See To Replace Au-
ger Shear Bolt in the Service and
Adjuetment section.

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.
