TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Multi-viscosity oils (5W30, 10W30 etc.) improve
starting in cold weather, and you should check your engine
oil level 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. 14)
NOTE: Before tipping lawn mower to drain oil, empty 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 plug.
2. Remove engine oil cap; lay aside on a clean sur-
face.
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 mower or side of engine.
5. Slowly pour oil down the oil fill spout, stopping every
few ounces to check the oil level with the dipstick.
6. Stop adding oil when you reach the FULL mark on the
dipstick. Wait a minute to allow oil to settle.
7. Continue adding small amounts of oil, rechecking the
dipstick until oil level settles at FULL. DO NOT overfill,
or engine will smoke heavily from the muffler on startup.
8. Always be sure to retighten dipstick before starting engine.
9. Re con nect spark plug wire to spark plug.
AIR FILTER (See Fig. 15)
Your engine will not run properly and may be damaged by
using a dirty air filter. Replace the air filter cartridge every
100 hours of op er a tion or every season, which ev er occurs
first. Service air cleaner more often under dusty conditions.

or after every 100 hours of operation, whichever occurs
first. Spark plug type and gap setting are shown in the
"PROD UCT SPEC I FI CA TIONS" section of this manual.

•
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 / wheels free of 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.
CLEAN UNDER DRIVE COVER
Clean under drive cover at least twice a season. Scrape
underside of cover with putty knife or similar tool to remove
13
any build-up of trash or grass on underside of drive cover.
