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.
• An approved LPG detector installed in trailers
and storage areas is recommended.
• 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.
DANGER
LPG fuel is extremely flammable and vapors are
explosive.
• In case of fire take the following steps:
1. If you can safely do so, stop the flow of gas
as quickly as possible. Never put out the
flame unless the gas can be shut off.
2. Notify the Fire Department and clear the
immediate area of all people.
3. When the gas flow is stopped, put out the
fire. Usually when flow of gas is cutoff,
fire will automatically stop.
4. If gas flow cannot be immediately stopped,
direct water on the tanks to keep them
cool, but do not put out the fire.
• Storage locations and trailers should be
equipped with at least one approved portable
fire extinguisher that has a minimum capacity
of 8.2 kg (18 lb) dry chemical with a B:C rating.
Do not use Carbon Tetrachloride extinguishers
(Pyrene etc.).
Changing the LPG Tank
Change the LPG tank outdoors in a well ventilated area.
Important: Only hand tighten tank connection fitting.
Over tightening by the use of tools may cause damage.
If hand tightening does not stop a leak, contact trained
and qualified personnel immediately.
1. Stop the machine on level ground, disengage the blade
control switch (PTO), move the motion control levers
to the neutral locked position, and set the parking
brake.
2. Wait for all moving parts to stop before leaving the
operating position.
3. With the engine running, close the fuel valve on the
tank.
4. Run the engine until it stops.
Note: This purges all vapors from the hose.
5. Remove the key.
6. Carefully disconnect the LPG fuel hose.

valves, fittings, or other tank components.
• Only use the Toro approved LPG tank,
fittings, and hoses that were designed for
your mower.
