Storage
If engine will be out of service for 2 months or more follow procedure below.
1. Coolant (anti-freeze) mixture should be in good condition and tested to guard against freezing in
cold temperatures. Recommended 50/50 mixture will normally provide protection down to
temperatures of -34°F (-37°C). If storage temperatures will fall below this, cooling system should
be drained completely. A note should then be attached to equipment and/or engine as a reminder
to refi ll cooling system before starting.
2. 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).
3. Change oil while engine is still warm from operation. 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.
4. Disconnect negative (-) battery cable.
5. Store engine in a clean, dry place.
Troubleshooting
Do not attempt to service or replace major engine components, or any items that require special
timing or adjustment procedures. This work should be performed by a Kohler authorized dealer.
