CHECKS BEFORE STARTING
• Check that the crankcase oil is filled to full mark on
dipstick.
• Fill the fuel tank with fresh fuel.
FUEL RECOMMENDATIONS
For daily operation: Use only unleaded gasoline with a
pump sticker octane rating of 87 or higher. Gasohol (up
to 10% ethyl alcohol, 90% unleaded gasoline by volume)
is approved as a fuel. Methyl Teriary Butyl Ether (MTBE)
and unleaded gasoline blends (up to a maximum of 15%
MTBE by volume) are approved as a fuel. No other
gasoline/alcohol or gasoline/ether blends are approved.
Do not use fuel additives other than fuel stabilizer.
For storage: CAUTION: 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 always use fuel stabilioer,
especially before storage of 30 days or longer. 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 add fuel:
1. Remove the fuel cap (B, Figure 2).
2. Fill the tank. Do not overfill. Leave room in the tank
for fuel expansion.
3. Install and hand tighten the fuel cap.

WARNING
Never operate on slopes greater than 17.6 percent
(10 °) which is a rise of 3-1/2 feet (106 cm)
vertically in 20 feet (607 cm) horizontally.
Select slow ground speed before driving onto a
slope. Use extra caution when operating on
slopes with a rear-mounted grass catcher.
Mow up and down the face of slopes, not across.
Use caution when changing directions and DO
NOT START OR STOP ON A SLOPE.
WARNING
Never allow passengers to ride on the unit.
Before leaving the operator's position for any
reason, engage the parking brake, disengage the
PTO, stop the engine and remove the key.
To reduce fire hazard, keep the engine, rider and
mower free of grass, leaves and excess grease.
Do not stop or park rider over dry leaves, grass or
combustible materials.
Gasoline is highly flammable and must be
handled with care. Never fill the tank when the
engine is still hot from recent operation. Do not
allow open flame, smoking or matches in the area.
Avoid over-filling and wipe up any spills.
WARNING - TRAILERS
Do not load this zero-turn rider on a trailer or
truck using two separate ramps. Only use a
single ramp that is at least one foot wider than
the width of the rear wheels of this rider. This
rider has a zero turning radius and the wheels
could fall off the ramps, or the rider could tip over
injuring the operator or bystanders.
