PERIODIC MAINTENANCE
PROCEDURES
Perform the following maintenance after the initial
50 hours of operation.
• Changing the Engine Oil and Replacing the
Engine Oil Filter Element
• Changing the Fuel Filter Element
Changing the Engine Oil and Replacing the
Engine Oil Filter Element
The engine oil on a new engine becomes
contaminated from the initial break-in of internal
parts. It is very important that the initial oil
replacement is performed as scheduled.
It is easiest and most effective to drain the engine
oil after operation while the engine is still warm.
WARNING! If you must drain the engine oil
while it is still hot, stay clear of the hot engine
oil to avoid being burned. ALWAYS wear eye
protection.

1. Turn the engine OFF.
2. Remove the engine oil dipstick. Attach the oil
drain pump (if equipped) and pump out the oil.
For easier draining, remove the engine oil fill
cap. NOTICE: Prevent dirt and debris from
contaminating engine oil. Carefully clean the
dipstick and the surrounding area before you
remove the dipstick.
3. Turn the engine oil filter (Figure 4-1, (1))
counterclockwise with a wrench.
4. Remove the engine oil filter.
5. Apply a small amount of engine oil to the seal of
the new filter.

8. Remove filler cap (Figure 4-2, (1)) and fill with
new engine oil through filler port. See Adding
Engine Oil on page 3-23. NOTICE: NEVER mix
different types of engine oil. This may adversely
affect the lubricating properties of the engine
oil. NEVER overfill. Overfilling may result in
white exhaust smoke, engine overspeed or
internal damage.
9. Perform a trial run and check for oil leaks.
10. Approximately 10 minutes after stopping the
engine, remove the oil dipstick and check the oil
level. Add oil if the level is too low.
11. Dispose of waste properly. NOTICE: ALWAYS
be environmentally responsible.
