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.).
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 for the mower deck 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. This purges all vapors
from the hose.
5. Remove the key.
6. Carefully disconnect the LPG fuel hose.
