Kohler — Oil Change

A Kohler service procedure — check it applies to your exact model before use.

Procedure

1. Add Kohler PRO Series fuel treatment or equivalent to fuel tank. Run engine 2-3 minutes to get stabilized fuel into fuel system (failures due to untreated fuel are not warrantable).
2. Change oil while engine is still warm from operation (NOT required if using KOHLER PRO 10W-50 full-synthetic oil). Remove spark plug(s) and pour about 1 oz. of engine oil into cylinder(s). Replace spark plug(s) and crank engine slowly to distribute oil.
3. Disconnect negative (–) battery cable.
4. Store engine in a clean, dry place. 5 Speciﬁ cations 32 690 03 Rev.
