II. SLOPE OPERATION
Slopes are a major factor related to slip
and fall accidents which can result in
severe injury. All slopes require extra
caution. If you feel uneasy on a slope, do
not mow it.
DO:
• Mow across the face of slopes: never
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT."
• Do not trim near drop-offs, ditches or
embankments. The operator could lose
footing or balance.
• Do not trim excessively steep slopes.
• Do not mow on wet grass. Reduced
footing could cause slipping.
II1.CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.
Children are often attracted to the
machine and the mowing activity. Never
assume that children will remain where
you last saw them.

and under the watchful care of another
responsible adult,
• Be alert and turn machine off if children
enter the area.

manufacturer's recommended parts,
when necessary.

theengine. 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 lawnmowar 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 oilto settle down into
engine for accurate reading. To read
proper level, tighten engine oil cap, then
remove it to road 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 ever./25 hours of
operation or each season. You may
need to change the oil more often
under dusty, dirty conditions.
ADD GASOLINE
• 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.
AWARNING: 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
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or
use gasoline near an open flame.
