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.
– The LPG tank should be free of dents or
damage. If the tank show signs of dents or
damage, replace it immediately.
– Check the valve and fitting openings for dirt
and debris.
– Slowly open the valve all the way and listen
for a continuous hiss from the regulator, it
may indicate a leak.
– LPG has a rotten egg or skunk smell added
to it to help detect a gas leak. If you detect
a gas leak:
◊ Turn off the LPG valve if you can safely
do so.
◊ Leave the area.
◊ Contact trained and qualified personnel
immediately.
– Do Not use if the hoses are abraded, damaged,
kinked, or flattened.
– Make sure the tank is securely mounted to
the mower. If the tank is loose, the hose or
fittings may leak.
• With each tank change:
– Check all gauges, fittings, and valves for
damage.
– Look for deterioration, damaged or missing
o-rings on tank connection fitting.
