HOW TO CHECK THE OIL
NOTE: Do not check the level of the oil while the engine runs.
1.
Make sure the unit is level.
2.
Clean
the area around
the dipstick
(Figure
24). Remove
the
dipstick.
Wipe the oil from the dipstick.
3.
Insert the dipstick
into the oil fill tube. Turn the dipstick
clock-
wise until it is tight. Remove
the dipstick.
Check the oil level on
the dipstick,
The oi! level must
reach
the FULL
mark on the
dipstick.
4.
If necessary,
add oil until the oil reaches
the FULL mark on the
dipstick.
The
quantity
of oil needed
from
ADD
to FULL
is
shown
on the dipstick.
Do not add too much oi!.

Dipstick
Remove the oil drain plug. Drain the oil completely from the
engine, install and tighten the oil drain plug.
Only
use a high quality
detergent
oil rated
with API
service
classification
SG, SH, SJ or SL. Select
the oil's SAE viscosity
grade according
to the expected
operating
temperature
using
the temperature
chart below:
NOTE:
Synthetic
oil meeting
ILSAC
GF-2,
API certifica-
tion mark and API service
symbol
(shown
at left) with "S J/
CF ENERGY
CONSERVING"
or higher,
is an acceptable
oil at all temperatures.
Use of synthetic
oil does
not alter
required
oil change
intervals.

HOW TO CHANGE
THE OIL
NOTE: Do not drain the oil from a cold engine. Before you drain
the oil, let the engine run for several minutes. Make sure you do
not get oil on the belts.
1.
With the engine OFF but still warm, place the engine level and
disconnect the wire from the spark plug.
*
CAUTION:
Air
cooled
engines
run
hotter
than
automotive
engines.
The use of non-synthetic
multi-viscosity
oils
(5W-30,
10W-30,
etc.)
in temperatures
above
40 ° F (4 ° C) will result in
higher
than
normal
oil
consumption.
When
using
a
multi-viscosity
oil, check
oil level more frequently.
**
CAUTION:
SAE 30 oil, if used below
40 ° F (4 ° C), will result in
hard
starting
and
possible
engine
bore
damage
due
to
inadequate
lubrication.
NOTE: Although
multi-viscosity
oils (5W30, 10W30,
etc.)
improve starting in cold weather, they will result in increased
oil consumption when used above 320 F. Check the engine oil
level more frequently to avoid possible engine damage from
running low on oil.
4.
5.
Clean
the area
around
the dipstick.
Remove
the dipstick.
Slowly
pour approximately
48 ounces
(3 pints)
of oil into the oil
fill tube.
Insert the dipstick into the oil fill tube. Turn the dipstick in a
clockwise direction until it is tight. Remove the dipstick.
Check
the oil level on the dipstick.
The oil level must reach the FULL
mark on the dipstick.
HOW TO CLEAN
THE COOLING
SYSTEM
The engine
is air cooled.
The air that cools the engine
enters through
the air screen
on top of the engine. Clean the air screen
every
100
hours
or every year
as follows.
1.
Remove any grass, dirt or debris from the air screen with a
cloth or brush (see Figure 24).
2.
Inspect the edge of the engine
shroud
for grass or debris.
Remove any grass or debris visible at the bottom edge of the
engine shroud.

HOW TO CHECK THE MUFFLER
26
Check
the muffler every 50 hours. Make sure the muffler
is correctly
mounted
and is not loose. If the muffler is worn or burnt, replace
with
a new muffler.
A worn
muffler
is a fire hazard
and can damage
the
engine.
If you mount
a spark
arrester
to the muffler,
also check
the spark
arrester
when you check the muffler.
If the spark arrester
is worn or
damaged,
replace
it with a new spark
arrester
purchased
from a
Sears
Service
Center.
