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.
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.
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.
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
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.
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.
