MAINTENANCE

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service classiﬁ cation SG–SL. Select the oil's SAE viscosity grade according to your expected operating temperature.

SAE VISCOSITY GRADES

							SAE 30
			5W-30

F	-20	0			30 32 40		60	80	100
C	-30	-20		-10	0	10	20	30	40

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 ﬁ ve (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, empty fuel tank by running engine until fuel tank is empty.

5.Slowly pour oil down the oil ﬁ ll 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 overﬁ ll, or engine will smoke heavily from the mufﬂer on startup.

9.Reconnect spark plug wire to spark plug.

AIR FILTER (See Fig. 13)

Your engine will not run properly and may be damaged by using a dirty air ﬁ lter. Replace the air ﬁ lter cartridge every 100 hours of operation or every season, whichever occurs ﬁ rst. Service air cleaner more often under dusty conditions.

Inspect and replace corroded mufﬂ er as it could create a ﬁ re hazard and/or damage.

SPARK PLUG

Replace spark plug 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 SPECIFIC ATIONS” 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 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 ﬁ nished surfaces/wheels free of gasoline, oil, etc.

•We do not recommend using a garden hose to clean lawn mower unless the electrical system, mufﬂ er, air ﬁ lter 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 un- derside of cover with putty knife or similar tool to remove any

11build-up of trash or grass on underside of drive cover.
