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 to "Belt
Adjustment"
in the
Service
and Adjustment
section).
LUBRICATION
- EVERY
10 HOURS
1.
Auger
Shaft
- Using
a hand grease
gun, lubricate
the auger shaft zerk
fittings
(A) every ten (10) operating
hours.
Each time a shear
bolt is re-
placed,
the auger shaft
MUST be
greased.
See Figure

Replace Auger Shear Bolt in the
Service and Adjustment section.
