Cutting Height Adjustment Lever

This lever, located at each wheel, lets you adjust cutting height of the grass. Remember to put all four levers at the same height to avoid uneven cut.

Primer

The primer is used to pump gas into the carburetor. Use it to assist in starting a cold engine, but do not use it when restarting a warm engine after a short shutdown.

Throttle Control

The engine is equipped with a constant speed throttle for maximum engine and cutting performance.

Recoil Starter

The recoil starter is attached to the handle. Stand behind the unit and pull the recoil starter to start engine.

Mulching Plug

The mulching plug is used only for mulching purposes. Instead of collecting the grass clippings in a grass catcher, some mower models have the option of recirculating the clippings back to the lawn. This is called mulching.

SECTION 5: OPERATING YOUR LAWN MOWER

Gas and Oil Fill-Up

WARNING: Never fill fuel tank indoors, or when engine is running or hot. Do not smoke when filling up the fuel tank.

Service the engine with gasoline and oil as instructed in the separate engine manual packed with your mower. Read instructions carefully.

Before Starting Mower

Attach spark plug wire to spark plug. Make certain the metal cap on the end of the spark plug wire is fastened securely over the metal tip on the spark plug.

Starting Engine

Push the primer three times. Wait two seconds between each push. In temperatures below 55° F, prime five times. Do not prime to restart a warm engine after a short shutdown.

Standing behind the mower, depress the blade control handle and hold it against the upper handle.

WARNING: Be sure no one other than the operator is standing near the lawn mower while starting engine or operating mower.

WARNING: Never run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and deadly gas.

WARNING: Keep hands, feet, hair and loose clothing away from any moving parts on engine and lawn mower.

Grasp starter handle and pull rope out slowly until engine reaches start of compression cycle (rope will pull slightly harder at this point). Let the rope rewind slowly. Pull rope with a rapid, continuous, full arm stroke. Keeping a firm grip on the starter handle, let the rope rewind slowly.

Stopping Engine

Release blade control handle to stop the engine and the blade.

Disconnect spark plug wire and move away from spark plug to prevent accidental starting.
