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.
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, dean, 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.
CAUTION; Fill to bottom of gas tank
filter neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or 
use gasoline near an open flame.

do flood engine, wait a few minutes 
before attempting to start and do not 
repeat priming steps.
