top slot in filler hole. Pour oil slowly.
Do not over fill.
NOTE: Allow oil to settle down into engine

• Check oil level before each use.
Add

Fill to the top slot in filler
hole.

under dusty, dirty conditions.
ADD GASOLINE

clean, regular
unleaded
gasoline

of
87 octane.
Do not mix oil with gase-
line.
Purchase
fuel in quantities
that
can be used within 30 days to assure
fuel freshness.
_kWARNING:
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 START ENGINE
NOTE: Due to protective coatings on the
engine, a small amount of smoke may be 8
present during the initial use of the
product and should be considered
normal.
1. 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.
2. 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
• 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.
