Your Hustler Hydro WalkBehind was adjusted before it
left the factory and was checked during predelivery setup.
However, after start-up and continued use, a certain amount
of break-in wear will cause some adjustments to change.
Remain alert for unusual noises, they could be signaling
a problem. Visually inspect the machine for any abnormal
wear or damage. A good time to detect potential problems
is while performing scheduled maintenance service.
Correcting the problem as quickly as possible is the best
insurance.
WARNING: Keep your machine clean and
remove heavy deposits of trash and clippings,
they can cause engine fires and hydraulic
overheating as well as excessive belt wear.

especially in the area of reservoir, engine oil and engine
combustion air; minute dust particle are abrasive to close-
