5.1.10 Check Spark Arrester
Kohler EFI engines only:
POTENTIAL HAZARD
Hot exhaust system components may ignite gasoline
vapors even after the engine is stopped.
Hot particles exhausted during engine operation may
ignite flammable materials.
WHAT CAN HAPPEN
Fire may result in personal injury or property damage.
HOW TO AVOID THE HAZARD
Do NOT refuel or run engine unless spark arrester is
installed.
a) Shut off engine, remove key, and wait for all moving parts to stop.
b) Wait for muffler to cool.
c) If any breaks in the screen or welds are observed, replace arrester.
d) If plugging of the screen is observed, remove arrester and shake loose particles
out of the arrester and clean screen with a wire brush (soak in solvent if
necessary). Re-install arrester on exhaust outlet.
5.1.11 Change engine oil:
Service Interval: 100 hrs.
NOTE: Change oil and filter after first five (5) hrs. of operation.
a) Stop engine, wait for all moving parts to stop, and remove key.
b) Drain oil while engine is warm from operation.
c) The oil drain valve is located on right hand side of engine.
Place pan under machine to catch oil and open valve with a 10 mm wrench.
Allow oil to drain, then close valve.
d) Replace the oil filter every other oil change. Clean around oil filter and
unscrew filter to remove. Before reinstalling new filter, apply a thin coating of
oil on the surface of the rubber seal. Turn filter clockwise until rubber seal
contacts the filter adapter then tighten filter an additional 2/3 to 3/4 turn.
e) Clean around oil fill cap and remove cap. Fill to specified capacity and replace
cap. Use oil recommended in engine owner's manual. DO NOT overfill.
f) Start the engine and check for leaks.
5.1.12 Check hydraulic oil level:
Service Interval: 40 hr.
a) Stop engine and wait for all moving parts to stop.
b) Unhook seat latch and tilt seat up.
c) Clean area around hydraulic reservoir cap and remove cap. Oil level should
be to the top of the baffle inside the tank. If not, add oil. Use only Mobil 1
15W-50 synthetic motor oil. Replace hydraulic reservoir cap and tighten
until snug. Do not overtighten.
NOTE: The baffle is labeled "HOT" and "COLD". The oil level varies with
the temperature of the oil. The "HOT" level shows the level of oil when it is
at 225°F (107°C). The "COLD" level shows the level of the oil when it is at
75°F (24°C). Fill to the appropriate level depending upon the temperature
of the oil. For example: If the oil is about 150° F (65°C), fill to halfway
between the "HOT" and "COLD" levels. If the oil is at room temperature
(about 75° F (24°C)), fill only to the "COLD" level.
Service Interval: 50 hours
