Safety

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 flame unless gas can be shut off.

2.Notify the Fire Department and clear immediate area of all people.

3.When 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 tanks to keep them cool, but Do Not put out fire.

Storage locations and trailers should be equipped with at least one approved portable fire extinguisher having a minimum capacity of 18 lb (8.2 kg) dry chemical with a B:C rating. Do Not use Carbon Tetrachloride extinguishers (Pyrene etc.).

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 of vapors.

Keep away from vent valve.

Keep away from eyes and skin.

Contact trained and qualified personnel if tank shows signs of frosted areas, makes a hissing sound, or emits a foul odor.

Obtain immediate medical attention if contact occurs with vapors or liquid.

Check that the operator’s presence controls, safety switches, and shields are attached and functioning properly. Do Not operate unless they are functioning properly.

Inspection

It is very important to check the LPG tank and components for wear or leaks.

Important: Never check for leaks using an open flame.

Important: Never use bare hands when checking the fitting or valve. Escaping LPG vapor and liquid freezes skin on contact.

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.

Before each use:

Visually inspect the tank, hose, and fitting and be alert to a foul odor coming from the tank.
