LUBRICATION
Use only high quality detergent oil rated with API service
classification SF-SJ. Select the oil's SAE viscosity grade
according to your expected operating temperature.
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at least
once a year if the lawn mower is not used for 25 hours in one
year.
Check the crankcase oil level before starting the engine and
after each five (5) hours of continuous use. Tighten oil plug
securely each time you check the oil level.
TO CHANGE ENGINE OIL (See Fig. 12)
NOTE: Before tipping lawn mower to drain oil, drain fuel tank
by running engine until fuel tank is empty.
1.
Disconnect spark plug wire from spark plug and place
wire where it cannot come in contact with spark plug.
2. Remove engine oil cap; lay aside on a clean surface.
3. Tip lawn mower on its side as shown and drain oil into a
suitable container. Rock lawn mower back and forth to
remove any oil trapped inside of engine.
4. Wipe off any spilled oil from lawn mower or side of
engine.
5. Fill engine with oil. (See “ADD OIL” in the Operation
section of this manual.)
6. Reconnect spark plug wire to spark plug.

AIR FILTER
Your engine will not run properly and may be damaged by
using a dirty air filter. Replace the air filter every 100 hours
of operation or every season, whichever occurs first. Ser-
vice air cleaner more often under dusty conditions. See the
maintenance section of your engine manual.
MUFFLER
Inspect and replace corroded muffler as it could create a fire
hazard and/or damage.
SPARK PLUG
Replace spark plugs at the beginning of each mowing
season or after every 100 hours of operation, whichever
occurs first. Spark plug type and gap setting are shown in
the “PRODUCT SPECIFICATIONS” section of this manual.
CLEANING
IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER
HOUSING FREE OF BUILT-UP GRASS AND TRASH.
CLEAN THE UNDERSIDE OF YOUR MOWER AFTER EACH
USE.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with spark plug.
• Clean the underside of your lawn mower by scraping to
remove build-up of grass and trash.
• Clean engine often to keep trash from accumulating. A
clogged engine runs hotter and shortens engine life.
• Keep finished surfaces and wheels free of all gasoline,
oil, etc.
• We do not recommend using a garden hose to clean lawn
mower unless the electrical system, muffler, air filter
and carburetor are covered to keep water out. Water in
engine can result in shortened engine life.
