4.3.3 OIL & OIL FILTER CHANGE PROCEDURE
To change the oil, proceed as follows:
1. Start the engine by moving the AUTO/OFF/MANUAL switch to
MANUAL and run until it is thoroughly warmed up. Then shut
OFF the engine by moving the switch to the OFF position.
2. Immediately after the engine shuts OFF, pull the oil drain hose
(Figure 4.4) free of its retaining clip. Remove the cap from the
hose and drain the oil into a suitable container.
3. After the oil has drained, replace the cap onto the end of the
oil drain hose. Retain the hose in the clip.
Change the engine oil filter as follows:
1. With the oil drained, remove the old oil filter by turning it
counterclockwise.
2. Apply a light coating of clean engine oil to the gasket of the
new filter. See the Specifications section for recommended
filter.
3. Screw the new filter on by hand until its gasket lightly contacts
the oil filter adapter. Then, tighten the filter an additional 3/4 to
one turn (Figure 4.4).
4. Refill with the proper recommended oil (see the Engine Oil
Recommendations section). See the Specifications section
for oil capacities.
