INSTALLATION & OPERATION MANUAL

2. ENGINE BREAK-IN

Initial Break-in Procedure
The first 20 hours of operation is the engine break-in period. During this period, it is
important that the engine is operated as outlined.
1) DO NOT operate engine at idle rpm for extended periods of time during the first 10
hours.
2) DO NOT operate at any one constant speed for extended periods of time.
3) DO NOT exceed 75% of full throttle during the first 10 hours except during the engine
initial Break-In Procedure. During the next 10 hours, occasional operating at full throttle
(5 minutes at a time maximum) is permissible.
4) AVOID full throttle accelerations from neutral position.
5) DO NOT operate at all full throttle until engine reaches normal operating temperature.
6) FREQUENTLY CHECK engine oil level and add oil if necessary.

3. STOPPING THE ENGINE

The engine should be run for a few minute at idle (in neutral) before turning it off. This will
avoid boiling the cooling system and even out the temperature.
This is especially important if the engine has been operated at high engine speeds and/or
with heavy loads.
Shutting down the engine in this fashion will extend the life of your engine.
