Replace Engine Oil and Engine Oil
Filter
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 change 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 the engine oil
must be drained while it is still hot, stay
clear of the hot engine oil to avoid being
burned.
1. Turn the engine off.
2. NOTICE: Prevent dirt and debris from
contaminating engine oil. Carefully clean
the dipstick and the surrounding area
before removing the
dipstick. Remove the engine oil dipstick.
Attach the oil drain pump and pump out
the oil.
For easier draining, remove the engine
oil fill cap (Figure 2, (2)) (yellow) at the
top of the rocker arm cover. Dispose of
used oil properly. NOTICE: ALWAYS be
environmentally responsible.
3. Remove the engine oil filter
(Figure 2, (1)) with a filter wrench (turn
counterclockwise).
4. Clean the filter installation face, attach
the new full-flow oil filter and tighten by
hand until the seal touches.
5. Turn the full-flow oil filter an additional 3/4
of a turn clockwise with the filter wrench.

6. Fill with new engine oil. See Adding
Engine Oil on page 28. 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.
7. Perform a trial run and check for oil leaks.
8. Approximately 10 minutes after stopping
the engine, remove the oil dipstick and
check the oil level. Add oil if the level is
too low.
CAUTION! Be careful not to get any oil
on the V-belt. Oil on the belt causes
slipping and stretching. Replace the belt
if it is damaged.
