BEFORE STARTING ENGINE

OIL

Your lawn mower is shipped without oil in the engine.

• Be sure mower is level and area around oil fill is clean.

• Remove engine oil plug and fill to the

top of slot in filler hole.

NOTE: Allow oil to settle down into engine for accurate reading.

• Engine holds 20 ozs. of oil. For type and

grade of oil to use, see "ENGINE in

Maintenance section of this manual.

• Pour oil slowly. Do not over fill.

• Check oil level before each use. Add oil if needed.

• Change the oil after every 25 hours of operation or each season. You may need

to change the oil more often under dusty, dirty conditions.

ADD GASOLINE

• Fill fuel tank.

Use fresh, clean, regular

unleaded gasoline with a minimum of 87 octane.

Do not mix oil with gasoline.

Purchase fuel in quantities that can be used within 30 days to assure fuel freshness.

AWARNING: Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage.

Acidic gas can damage the fuel system of an

engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer.

Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season.

See Storage Instructions for additional information.

Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

ACAUTION: Fill to bottom of gas tank filler neck.

Do not overfill.

Wipe off any spilled oil or fuel.

Do not store, spill or use gasoline near an open flame.

Gasoline filler cap

Engine oil plug

TO START ENGINE

• To start a cold engine, push primer three (3) times before trying to start.

Use a firm push. This step is not usually necessary when starting an

engine which has already run for a few minutes.

• Hold operator presence control bar

down to the handle and pull starter handle quickly.

Do not allow starter rope to snap back.

• To stop engine, release operator

presence control bar.

NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather over priming may cause flooding and engine will not start.

If you

do flood engine, wait a few minutes before attempting to start and do not repeat priming steps.

MOWING TIPS

• Under certain conditions, such as very tall grass, it may be necessary to raise the height of cut to reduce pushing effort and to keep from overloading the engine and leaving clumps of grass clippings.

It may also be necessary to reduce ground speed and/or run the lawn mower over the area a second time.

• For extremely heavy cutting, reduce the width of cut by overlapping previously cut path and mow slowly.

• For better grass bagging and most cutting conditions, the engine speed should be set in the fast position.

• When using a rear discharge lawn mower in moist, heavy grass, clumps of cut grass may not enter the grass catcher.

Reduce ground speed

(pushing speed) and/or run the lawn mower over the area a second time.

• If a trail of clippings is left on the right side of a rear discharge mower, mow in a clockwise direction with a small overlap to collect the clippings on the next pass.

• Pores in cloth grass catchers can become filled with dirt and dust with use and catchers will collect less grass.

To prevent this, regularly hose catcher off with water and let dry before using.

• Keep top of engine around starter clear and clean of grass clippings and chaff.

This will help engine air flow and extend engine life.
