• Reinstall engine oil plug and tighten.
• 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.
GAS
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. (Use of leaded gasoline will
increase carbon and lead oxide deposits
and reduce valve life). Do not mix oil
with gasoline. Purchase fuel in quanti-
ties that can be used within 30 days to
assure fuel freshness.
WARNING:
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.

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 (push-
ing 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.
