Kubota WG1903-G-E3 Operator's Manual page 9

A If running the engine on LPG, use the standard LPG fuel
recommended by KUBOTA. The use of other fuel may
cause a hazardous or dangerous condition.
A LPG fuel in the gaseous state is heavier than air and will
settle in low areas, this may be hazardous.
Please follow all operator's manual instructions when
changing the fuel tank and servicing the fuel system.
6. EXHAUST GASES & FIRE PREVENTION
A Engine exhaust fumes can be very harmful if allowed to
accumulate. Be sure to run the engine in a well ventilated
location and where there are no people or livestock near
the engine.
A The exhaust gas from the muffler is very hot. To prevent
a fire, do not expose dry grass, mowed grass, oil or any
other combustible materials to exhaust gas. Keep the
engine and muffler clean at all times.
A To avoid a fire, be alert for leaks of flammable
substances from hoses and lines. Be sure to check for
leaks from hoses or pipes, such as fuel and hydraulic
fluid by following the maintenance check list.
A To avoid a fire, do not short across power cables and
wires. Check to see that all power cables and wirings are
in good condition. Keep all electrical connections clean.
Bare wire or frayed insulation can cause a dangerous
electrical shock and personal injury.
7. ESCAPING FLUID
A Relieve all pressure in the air, the oil and the cooling
systems before disconnecting any lines, fittings or
related items.
A Be cautious of
disconnecting any device from a pressurized system that
utilizes pressure. DO NOT check for pressure leaks with
your hand. High pressure oil or fuel can cause personal
injury.
A Escaping fluid under pressure has sufficient force to
penetrate skin causing serious personal injury.
A Fluid escaping from pinholes may be invisible. Use a
piece of cardboard or wood to search for suspected
leaks: do not use hands and body. Use safety goggles or
other eye protection when checking for leaks.
A If injured by escaping fluid, see a medical doctor
immediately. This fluid can produce gangrene or severe
allergic reaction.
