-

Safety pictograms can be found on the engine and it is the 
operator's responsibility to keep them in a perfectly visible 
place and replace them when they are no longer legible.

the engines for technical or commercial reasons.

 

-

These changes do not require KOHLER to intervene on the 
marketed production up to that time and not to consider 
this manual as inappropriate. 

 

-

supply some time after the main text shall be kept together 
with the manual and considered as an integral part of it.

 1.3 Emission-Related Installation Instructions

Failing to follow the instructions in the applications guidebook when installing a certified engine in a piece of nonroad equipment 

violates federal law (40 CFR 1068.105(b)), subject to fines or other penalties as described in the Clean Air Act.

OEM must apply a separate label with the following statement: “ULTRA LOW SULFUR FUEL ONLY” near the fuel inlet.

Ensure you are installing an engine appropriately certified for your application. Constant speed engines may only be installed 

on constant speed equipment for constant speed operation.

If you install the engine in a way that makes the engine's emission control information label hard to read during normal engine 

maintenance, you must place a duplicate label on the equipment, as described in 40 CFR 1068.105.
