Using Stabilizer/Conditioner; Filling The Fuel Tank; Checking The Engine-Oil Level; Breaking In A New Machine - Toro 74731 Operator's Manual

DANGER
In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite the gasoline vapors. A fire or explosion
from gasoline can burn you and others and can
damage property.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior carpets
or plastic truck bed liners may insulate the
container and slow the loss of any static charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the equipment
with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
• If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.
WARNING
Gasoline is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep gas away from eyes and skin.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
•
Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
•
Cleans the engine while it runs
•
Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting
Important: Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to
the gas.
Note: A fuel stabilizer/conditioner is most effective
when mixed with fresh gasoline. To minimize the chance
of varnish deposits in the fuel system, use fuel stabilizer
at all times.

Filling the Fuel Tank

Note: Make sure the engine is shut off and the
motion-controls are in the P
Note: You can use the fuel window to verify the presence of
gasoline before filling the tank
Important: Do Not overfill fuel tank. Fill the fuel tank
to the bottom of the filler neck. The empty space in the
tank allows the fuel to expand. Overfilling may result
in fuel leakage or damage to the engine or emissions
system.

Checking the Engine-Oil Level

Before you start the engine and use the machine, check
the oil level in the engine crankcase; refer to
Engine-Oil Level (page

Breaking in a New Machine

New engines take time to develop full power. Mower decks
and drive systems have higher friction when new, placing
additional load on the engine. Allow 40 to 50 hours of
break-in time for new machines to develop full power and
best performance.
