Check Spark Arrester (if
equipped)
Service Interval: Every 50 hours
WARNING
Hot exhaust system components may ignite
gasoline vapors even after the engine is stopped.
Hot particles exhausted during engine operation
may ignite flammable materials. Fire may result in
personal injury or property damage.
Do Not refuel or run engine unless spark arrester
is installed.
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Wait for muffler to cool.
3. If any breaks in the screen or welds are observed,
replace the arrester.
4. If plugging of the screen is observed, remove the
arrester and shake loose particles out of the arrester
and clean screen with a wire brush (soak in solvent if
necessary). Reinstall arrester on exhaust outlet.
Fuel System
Maintenance
Inspecting the LPG System
Service Interval: Before each use or daily—Check the LPG
tank and components.
Every 40 hours—Check the LPG hoses, regulator and
connections.
It is very important to check the LPG tank and components
for wear or leaks.
Important: Never check for leaks using an open flame.
Important: Never use bare hands when checking the
fitting or valve. Escaping LPG vapor and liquid freezes
skin on contact.
•
Inspecting before each use:
– Visually inspect the tank, hose, and fitting and be alert
to a foul odor coming from the tank.
– 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.
•
Inspecting 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.)
