Changing the oil
NOTE: If the engine has been running, allow the
engine to cool before doing any mainte-
nance work.
NOTE: The oil should be changed after the first 5
hours of operation and every 25 hours there
after.
There are three methods of changing the oil. The
application the engine is mounted to will determine which
method to use:
Siphon the oil out through the dip stick tube
A. Insert the siphon hose into the dip stick tube. See
Figure 1.7.
B. Siphon the oil out of the engine by following the pro-
cedures provided by the siphon manufacturer.
Drain Plug in the bottom of the engine
A. Place an approved oil drain pan under the drain
plug.
B. Remove the drain plug using a 10 mm wrench. See
Figure 1.8.
NOTE: Some engines have a 7 mm square drain
plug. See Figure 1.9.
C. Allow all of the oil to drain into the oil pan.
D. Apply a small amount of releasable thread sealing
compound such as Loctite® 565 to the threads of
the drain plug.
E. Install the drain plug, tightening it to a torque of 124
- 150 in lbs (14 - 17 Nm).
