ADJUSTMENTS
WHEEL CREEP
"Creep" is when the engine is running and hydrostatic transmission is in neutral, but due to inadequate align-
ment, wheels still move. Do the following procedure to stop this motion.
1. Lift up and support machine so rear wheels are off the ground and can turn freely.
2. In the engine compartment, the hydrostatic transmission is on the left
side. The swash plate(D) is under the transmission and comes out
forward. The idler arm(B) has a bearing that runs in the notch of the
swash plate. Loosen bolt (A).
3. With engine running, move bearing(B) so it centers on the swash
plate(D) and 'wheel creep' stops.
4. Tighten all fasteners and test by using foot pedal linkage to see that
'creep' is removed.
5. Turn engine off and lower machine.

STORAGE
If the engine will be out of service for two or more months, use the following storage procedure.
1. Clean the exterior surfaces of the engine.
2. Change the oil and filter while the engine is still warm from operation.
3. The fuel system must be completely emptied, or the gasoline must be treated with a stabilizer to prevent
deterioration.
If you choose to use a stabilizer, follow manufacturers recommendations, and add the correct amount for
the capacity of fuel system. Fill fuel tank with clean, fresh gasoline. Run engine for 2-3 minutes to get
stabilized fuel into carburetor. Close fuel shut-off valve when unit is being stored or transported.
To empty the system, drain fuel tank and carburetor, or run engine until tank and system are empty.
4. Remove the spark plugs. Add one tablespoon of engine oil into each spark plug hole. Install plugs, but do
not connect the plug leads. Crank the engine two or three revolutions.
