MAINTENANCE

ENGINE 5.

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.

SAE VISCOSITY GRADES

"F -20 0 30 32 40 60 80 t00

°C -30 -20 -1; ; 1; 20 10 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 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, 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 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.

OIL FILLER CAP/DIPSTICK

FIG. 12

4. Wipe off any spilled oil from lawn mower or side of

engine.

Fill engine with oil. The engine oil capacity is 18.5 oz.

If oil is not completely drained from engine, you may

not need the entire container of a 20 oz. bottle of oil.

Slowly pour 3/4 of the oil from the container down the

oil fill spout into the engine.

6. Wait one minute to allow oil to settle. Use guage on oil

fill cap/dipstick for checking level. Insert dipstick into

the tube and rest the oil fill cap on the tube. DO NOT

thread the cap into the tube when taking reading.

7. Continue adding small amounts of oil and rechecking

the dipstick until it reads full. DO NOT overfill, or engine

will smoke on startup.

8. Always be sure to retighten oil dipstick before starting

engine.

9. 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.

Service 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 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 SPECIFICATIONS" section of this manual.

CLEANING

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER

HOUSING FREE OF BUILT-UPGRASS AND TRASH. CLEAN

THE UNDERSIDE OFYOUR MOWER AFTER EACH USE.

I _lb CAUTION: Disconnect spark plug wire I

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 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.

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

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