46 2 3 1 Purging Due to the effects air has on efciency in hydr ostatic drive applications, it is critical that it is purged from the system. These purge procedur es should be implemented any time a hydrostatic system has been opened to facilitate maintenance or any additional oil has been added to the system.
47 Problem Cause The engine will not start. Blade lever is engaged. • Steering controls ar e not locked in neutral • position. Driver is not sitting in driver’s seat. • Parking brake is not activated.
48 Problem Cause The engine seems weak. Clogged air lter . • Fouled spark plugs. • Carburetor incorr ectly adjusted. • The engine overheats. Clogged air intake or cooling ns. • Engine overloaded.
49 Winter Storage At the end of the mowing season, the machine should be readied for storage (or if it will not be in use for longer than 30 days). Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carbur etor and disrupt engine function.
