HOW TO CHECK THE OIL
NOTE: Do not check the level of the oil while the engine runs.
3,
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 oil 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 oil.
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 "SJ/
CF ENERGY CONSERVING" or higher, is an acceptable
oil at all temperatures. Use of synthetic
oil does not alter
required
oil change intervals.

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.
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.
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.
