Tank Type and Refilling
Note: The LPG tank used on this mower is a special tank
with internal baffles designed for this application.
•
Horizontal Tank Specifications:
– Tank Material: Aluminum
– Capacity: 43.5 lb
– Disconnect coupling: Left hand ACME threaded
– Fuel Withdrawal: Vapor
– Fuel Shutoff Valve: Rotate clockwise to close.
– Type of fuel: HD5 grade propane
•
New tanks must be properly filled by trained and qualified
personnel.
•
Only use tanks recommended by Toro. Failure to do so
will result in improper operation of the fuel system.
Important: Using a liquid-withdrawal tank will result
in icing or freezing of the LPG regulator and prevent
the engine from operating. This may also result in
permanent fuel-system damage and the release of
highly-flammable-propane liquid or vapor.

Operation

Note: Determine the left and right sides of the machine
from the normal operating position.

Adding Fuel

LPG (liquefied-petroleum gas) is more commonly called
propane. LPG is a liquid fuel that is stored in a tank under
pressure. Before the liquid leaves the tank, it is converted into
a vapor. Since LPG is stored as both liquid and gas, it may
leak from joints or connections that are not sealed properly.
LPG becomes flammable when it is mixed with air.
The LPG information in this Operator's Manual is provided
only as a guide. Consult the NFPA 58: Liquefied Petroleum
Gas Code, 2008 Edition for additional safety information.
This National Fire Protection Association (NFPA) code
pertains to the handling, storing, transporting, and usage of
LPG.
Type of fuel: HD5 grade propane
CAUTION
Using overfilled tanks may result in
the release of highly concentrated and
extremely-flammable-liquid propane. Refer to the
Adding Fuel (page 15)
Never use propane tanks that are filled beyond 80%
capacity.
DANGER
LPG vapors and liquid escaping from the tank may
cause serious injury or death. Vapors or liquid may
cause suffocation, freezing of tissue, or frostbite.
• Store and service the mower in a well-ventilated
area.
• Install an approved LPG detector in trailers and
storage areas.
• LPG is heavier than air and may accumulate in
low lying areas, such as ditches, drains, or pits.
• Avoid breathing in vapors.
• Keep LPG vapors and liquid away from vent
valves.
• Keep LPG vapors and liquid away from your
eyes and skin.
• Contact trained and qualified personnel if the
tank shows signs of frosted areas, makes a
hissing sound, or emits a foul odor.
• Obtain immediate medical attention if vapors or
liquid come in contact with your eyes or skin.
