DANGER
LPG fuel is extremely flammable and vapors are
explosive.
A fire or explosion from LPG fuel can burn you,
others, and cause property damage.
• Never smoke around fuel tank(s) and stay away
from an open flame or where fumes may be
ignited by a spark.
• Extinguish all sources of spark or flame when
approaching LPG tanks or mowers. The
hazard increases for enclosed trailers or storage
locations where vapor leakage may occur and
collect.
• LPG is heavier than air and may accumulate in
low lying areas, such as ditches, drains, or pits.
• LPG tank(s) should be filled by trained and
qualified personnel only.
• Never tamper with or repair the tank(s); contact
trained and qualified personnel.
• Do not change the tank(s) when the engine is
running.
• Before disconnecting the hoses, close the fuel
valves on all of the tanks and allow the engine to
run until it stops to purge all of the LPG vapors
from the system.
• Store the tank(s) away from heat, sparks, or
open flames.
• Do not operate without the entire exhaust
system in place and in proper working condition.
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 you can shut off the gas.
2. Notify the fire department and clear the
immediate area of all people.
3. When the gas flow has stopped, put out
the fire. Usually, when flow of gas is cut
off, fire will automatically stop.
4. If you cannot immediate stop the gas flow,
direct water on to the tanks to keep them
cool, but do not put out the fire.
• Storage locations and trailers should be
equipped with at least 1 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 such
as Pyrene.
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. Shut off the machine on level ground, disengage the
blade-control switch (PTO), move the motion-control
levers to the
NEUTRAL
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.
