positions - if not, the switch may need to be adjusted or replaced.
Whenever the ZTM is on level ground with the engine running and the lap bars in their Neu- tral positions, the ZTM should not creep (I.E., move in the Forward or Reverse directions of travel). If this occurs, contact your Service representative for the procedure to reset the RTN mechanism on the hydrostatic pumps. If the hydrostatic pump RTN is adjusted, the control linkage must also be readjusted.
G.Storage
1.General: If your mower will not be in service for a few months, it should be stored in a dry location that is not subject to drastic changes in temperature. Before storing, the following maintenance procedures should be per- formed.
Note: For E.F.I. Tanks, disconnect the neg- ative lead of the battery for storage of 4 weeks or more.
a.Clean the mower. The entire tractor and cutting deck should be washed and cleaned.
b.Sharpen the blades so that the mower will be ready to use when needed.
c.Protect the metal surfaces. Repair scratches with the appropriate
d.Lubricate the mower.
e.Drain the engine oil. The engine should be warm so that all the oil drains. Replace the engine oil filter and refill the crankcase with fresh oil.
f.Gasoline Engine: Drain all the fuel. Close the fuel tank shutoff valve. Disconnect the fuel line from the carbuetor and put the end into an approved fuel container. Open the fuel tank shutoff valve and drain the fuel tank and line into the approved container. Replace the fuel line on the carburetor. Start the engine and allow it to run out of fuel. This will prevent gum and varnish deposits from forming. Replace the fuel fil- ter.
g.Gasoline Engine Only: Remove the spark plugs and pour approximately one ounce of oil into each cylinder. Crank the engine one or two turns to spread the oil evenly on the cylinder walls. Replace the spark plugs.
h.Disconnect, clean and make sure the bat- tery is fully charged.
i.Inspect the hydraulic hoses, lines and fit- tings. Replace as necessary.
j.Jack the mower up and store it on blocks to take the weight off of the tires.
2.To Put the Mower Back in Service:
a.Check the battery. Charge if necessary.
b.Gasoline Engine Only: Remove the spark plugs and wipe them off. Using the starter, crank the engine to pump the excess oil out of the spark plug holes. Replace the spark plugs and the ignition leads. Refill the fuel tank with fresh gasoline.
c.Check the level of the oil in the crankcase and the hydraulic tank.
d.Lower the mower off the block and check the tire pressure.
e.Push the mower outdoors and start the engine. Let the engine idle until it has warmed up completely (4 to 5 minutes).
