Safety
– 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.
– 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.

Install and maintain in working order a
spark arrester before using equipment
on forest-covered, grass-covered, or
brush-covered unimproved land.
