Safety
– Inspect the LPG tank and the fuel connection
joint for leaks. Use the following procedure
below to detect leaks:
◊ Apply an approved leak detector solution,
obtained from a trained and qualified LPG
distributor, or a thick non-ammonia soapy
water solution (50% non-ammonia soap
and 50% water). (A leak detector solution
that contains ammonia will cause the
fittings to corrode and leak.)
◊ Using a small brush or spray bottle, apply
the solution around all the fittings of the
LPG tank and the fuel connection joint.
◊ Slowly open the gas valve a half-turn.
◊ If bubbles are detected, the joint or fitting
has a leak. Shut off the valve, tighten
the leaking connection, and slowly open
the valve again. If bubbles still appear,
Do Not use the tank. If it is safe to do
so, remove the tank from your mower;
otherwise, contact trained and qualified
personnel immediately.
◊ If no bubbles are detected, the LPG tank
may be used.
• Weekly:
– Check the entire LPG fuel delivery system for
damage or deterioration.
– Check the entire LPG fuel delivery system for
leaks at all joints using the same method as
described in the previous section.
– Follow all the inspection checks as specified in
the two previous inspection sections.
• Tank Requalification:
– USDOT (United States Department of
Transportation) regulations require LPG tanks
to be inspected, requalified, and marked within
12 years of the manufacture date and on a
regular basis thereafter. Typically this occurs
when the tank is refilled; contact a trained and
qualified LPG tank provider for more details.
– Do Not fill the LPG tank if it is beyond the
requalification period.
– Do Not fill damaged or rusted LPG tanks.
Operation
WARNING
Operating engine parts, especially the muffler,
become extremely hot. Severe burns can occur
on contact and debris, such as leaves, grass,
brush, etc. can catch fire.
• Allow engine parts, especially the muffler, to
cool before touching.
• Remove accumulated debris from muffler and
engine area.
WARNING
Engine exhaust contains carbon monoxide,
which is an odorless deadly poison that can kill
you.
Do Not run engine indoors or in a small confined
area where dangerous carbon monoxide fumes
can collect.
• Operate only in daylight or good artificial light,
keeping away from holes and hidden hazards.
• Lightning can cause severe injury or death. If
lightning is seen or thunder is heard in the area,
Do Not operate the machine; seek shelter.
• Be sure all drives are in neutral and parking brake
is engaged before starting engine. Use seat belts
with the roll bar in the raised and locked position.
• Never operate the mower with damaged guards,
shields, or covers. Always have safety shields,
guards, switches and other devices in place and in
proper working condition.
• Never mow with the discharge deflector raised,
removed or altered unless there is a grass
collection system or mulch kit in place and
working properly.
• Do Not change the engine governor setting or
overspeed the engine.
• Park machine on level ground. Stop engine, wait
for all moving parts to stop, remove key and
engage parking brake:
– Before checking, cleaning or working on the
mower.
– After striking a foreign object or abnormal
vibration occurs (inspect the mower for
damage and make repairs before restarting
and operating the mower).
