formahon 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 for 30 days or longer. Drain
the gas tank, start the engine and let it run until the

Your Lawn Mower' is equipped with an Operator
Engine Control Bar which requires the operator
to be positioned behind the Lawn Mower Handle to start and operate the lawn mower.
TO STARTENGINE
°
Push engine speed control lever forward to HIGH
position.
*
To start a cold engine, push primer five (5) 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
priminfl steps. In warmer weather over pn'ming may
cause fTood.ngand engine will not start, lfy0u do floocl
engine wait a few minutes before attempting to start
and DO NOT repeat priming steps.
MOWINGTIPS
*
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_
* For extremely heavy cutting, reduce the width of
cut and raise the rear of the lawn mower housing one (1) wheel adjuster setting higher than the
front for better discharge of grass.
o For side discharge lawn mowers, cutting in a
counter_clockwise direction, starting at the outside
of the area to be cut, spreads grass clippings more
evenly and puts less load on the engine. To keep
clippings off of walkways, flower beds, etc., make
the first cuts in a clockwise direction.
° Keep top of engine around starter dear and clean
of grass c)ippings and chaff. This will help engine
air flow and extend engine life.
