10.
Rinse and dry the foam element thoroughly.
11.
Dip the foam element in clean engine oil, then squeeze
out the excess oil.
Note:
Excess oil in the foam element restricts the air
flow through the element and may reach the paper
filter and clog it.
12.

After the first 5 hours—Change the engine
oil.
Every 50 hours—Change the engine oil.
1.
Run the engine to warm the engine oil.
Note:
Warm oil flows better and carries more
contaminants.
WARNING
Oil may be hot after engine has been run, and
contact with hot oil can cause severe personal
injury.
Avoid contacting the hot engine oil when you
drain it.
2.
Stop the engine and wait for all moving parts to stop.
3.
Disconnect the wire from the spark plug.
4.
Place a suitable drain pan under the dipstick/oil drain.
5.
Clean around the dipstick.
6.
Remove the dipstick by rotating the cap
counterclockwise and pulling it out.
7.
Raise the
left
side of the mower to drain the oil from
the dipstick fill tube into the drain pan.
8.
After draining the oil, return the mower to its operating
position.
9.
Fill the crankcase to the upper limit mark on the
dipstick with fresh oil. Refer to the Filling the
Crankcase with Oil.
