CHANGING THE OIL AND OIL FILTER
Your engine is equipped with an oil filter. Change the oil and
filter after the first eight (8) hours of operation. Change
the oil and oil filter every 100 hours thereafter. If you are
using this engine under dirty or dusty conditions, or in
extremely hot weather, change the oil more often.
Use the following instructions to change the oil while the engine
is still warm:
1. Clean the area around the oil drain plug, remove the plug
and drain the oil completely into a suitable container
(Figure 1 or figure 3).

2. When the oil is drained, install and tighten the oil drain plug.
3. When changing the oil filter, use the
following instructions:
A) Locate filter (Figure 4 or figure 5).
B) Place a suitable container beneath the oil filter and turn
the filter counterclockwise to remove the filter.
C) Coat the gasket of a new filter with engine oil. Turn
the new filter clockwise until the gasket contacts
the filter adapter, then tighten an additional 3/4 turn.
4. Remove the oil fill cap and insert a clean funnel into the oil
fill opening. Fill the crankcase with the recommended oil
until the oil level is at the full point on the dipstick.
Approximately 2366ml (2.5 qt.) are required when changing
an oil filter. POUR SLOWLY.
5. When the crankcase is filled to the proper level, install and
tighten the oil fill cap. Start engine to fill oil filter,
recheck/correct oil level.

SERVICING THE AIR CLEANER
Your equipment's air cleaner system is one of the most
important items to maintain. The engine will not run properly and
may be damaged if it is run with a dirty air cleaner system.
Service or replace the paper air filter per schedule on page 7.
Service or replace the filter more often if the engine is operated
under dusty or dirty conditions. Clean the foam pre-filter (if
equipped) every 25 hours of operation, or sooner
under dusty or dirty conditions.
