NOTE
Keep spare Elements on hand to eliminate down time.
Make sure the clean Element has no holes or ruptures. Placing a bright light inside the Element and
inspecting the outside will show any holes or tears. Discard the Element if holes or tears are evident.
Reassemble the Air Cleaner. Make sure the large O-Ring is in place between the End Cap and the Body.
Engine Oil and Filter (250 Hours)
NOTE
The Engine oil and Filter should be changed after the first 50 hours of Engine break-in, and every 250 hours
thereafter. Use the following procedure:
1.
With the Engine warm, remove the crankcase Drain Plug. Some plugs are equipped with a
magnet to gather metal particles. Completely clean and flush away all metallic filings from
the Plug, and re-install it.
2. The Engine Oil Filter should be changed at every oil change interval. Remove and
discard the throw away Filter canister. Wipe the Gasket sealing area of the block with
a clean cloth.
NOTE
Your Engine Oil Filters have special by-pass valves built-in. Use ONLY quality Engine replacement
filters.
3. Apply a thin coat of clean oil to the new oil filter gasket. Spin tighten. Refill the
crankcase with new oil. Follow specifications for type and viscosity of the replacement
oil. See Section E - Fuels and Lubrication, in this manual.
4. After new oil has been added, run the Engine at idle speed until the oil pressure gauge
indicates oil pressure. Check for leaks at the Filter and Drain Plug. Re-tighten only as
much as necessary to eliminate leakage.
If the Engine still will NOT start, consult your nearest authorized Engine dealer.
NOTE
Only an authorized Engine dealer can perform WARRANTY Service on the Engine.
Fuel Filter (250 Hours)
The Fuel Filters (primary and secondary) will require occasional replacement to maintain a clean
and adequate fuel flow for maximum Engine horsepower. The frequency of Filter replacement will
depend on the cleanliness of available fuel, the care used in storing fuel supplies, and the conditions
in which the machine is operated. Refer to the Engine manual.
WARNING
Do NOT service the fuel system while you are smoking, near a flame or fire, with the Engine running
or while the engine is still hot.
Fuel Bleeding Procedures
(250 Hours)
Whenever the Fuel Filter is removed and replaced, or the Engine runs out of fuel, air MUST be
bled from the system. Refer to the Engine manual for instructions in proper bleeding procedures.
