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 prod-
uct and should be considered normal.
1. To start a cold engine, push primer
three (3) times before trying to start.
Use a fi rm 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 han dle and pull starter
handle quickly. Do not allow starter
rope to snap back.
NOTE: In cooler weather it may be
necessary to repeat priming steps. In
warmer weather over priming may cause
fl ooding and engine will not start. If you do
fl ood engine, wait a few minutes before
attempting to start and do not repeat
priming steps.
MOWING TIPS
CAUTION: Do not use de-thatcher
blade attachments on your mower. Such
attachments are hazardous, will damage
your mower and could void your warranty.
• Under certain conditions, such as very
tall grass, it may be nec es sary to raise
the height of cut to reduce pushing
effort and to keep from overloading the
engine and leaving clumps of grass clip-
pings. It may also be necessary to re-
duce ground speed and/or run the lawn
mower over the area a sec ond time.
• For extremely heavy cutting, re duce the
width of cut by over lap ping previously
cut path and mow slowly.
• For better grass bagging and most cut-
ting conditions, the engine speed should
be set in the FAST po si tion.
• Pores in cloth grass catchers can be-
come fi lled with dirt and dust with use
and catchers will collect less grass. To
prevent this, reg u lar ly 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 fl ow and extend
engine life.
ADD GASOLINE
• Fill fuel tank to bottom of tank fi ller neck.
Do not overfi ll. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. Do not mix oil with gasoline.
Purchase fuel in quan ti ties that can be
used within 30 days to assure fuel fresh-
ness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open fl ame.
CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or metha-
nol) can attract moisture which leads to
separation and for ma tion 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 stor age of 30
days or longer. Empty 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 In struc tions for
additional information. Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.
