BEFORE STARTING ENGINE

ADD OIL

Your lawnmower is shipped without oil in
the engine. Engine holds  20 oz. of  oil.
For type and grade of oil to use, see
“ENGINE” in Maintenance section of this
manual.
1. Be sure lawnmower is level and area

around oil fill is clean.

2. Remove engine oil cap  and fill to the

full line on the dipstick. Pour oil slowly.
Do not over fill.

NOTE

: Allow oil to settle down into engine

for accurate reading. To read proper level,
tighten engine oil cap, then remove it to
read the dipstick.
3. Reinstall engine oil cap and tighten.
• Check oil level before each use.  Add

oil if needed.  Fill to full line on dipstick.

• 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.

ADD GASOLINE
NOTE: 

Before filling fuel tank, remove

and discard the debris plug that is inside
the tank.
• Fill fuel tank.  Use fresh, clean, regular

unleaded gasoline with a minimum of
87 octane.  Do not mix oil with gaso-
line.  Purchase fuel in quantities 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 START ENGINE

NOTE:

 Due to protective coatings on the

engine, a small amount of smoke may be
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. Move throttle control lever to fast

position.

3. 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.

 CAUTION:  

Fill to bottom of gas tank

filler neck.  Do not overfill.  Wipe off any
spilled oil or fuel.  Do not store, spill or
use gasoline near an open flame.
