Battery cable should be disconnected before using “Fast Charge”.
Charge battery at 15 amps for 10 minutes or 7 amps for 30 minutes. Do not exceed the recommended
charging rate. If electrolyte starts boiling over, decrease charging.

2. Wear eye protection and rubber gloves.
3. Avoid breathing fumes when electrolyte is added.
4. Avoid spilling or dripping electrolyte.
Battery Electrolyte is an acidic solution and should be handled with care. If
electrolyte is splashed on any part of your body, ush all contact areas imme-
diately with liberal amounts of water. Get medical attention immediately.
Use of booster battery and jumper cables. Particular care should be used
when connecting a booster battery. Use proper polarity in order to prevent
sparks.

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.

do not connect the plug leads. Crank the engine two or three revolutions.
5. Store machine in a clean, dry place.

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.

the left side. The shift arm (D) is under the pump and comes
out the side. The idler arm (B) has a bearing that runs in the
notch of the shift arm. Loosen bolt (A).
3. With engine running, move bearing (B) so it centers on the
shift arm (D) and 'wheel creep' stops.
4. Tighten all fasteners and test by using foot pedal linkage to
see that 'creep' is removed.
