Mobil 1 15W50 or equivalent motor oil until oil just
appears at the bottom of each transaxle’s purge
port (approximately 2.5 qts. per transaxle, 5 qts.
total). Install the purge port plug into each trans-
axle as the oil level reaches this port.

Purging Procedure
NOTE:
Due to the effects air has on hydrostatic drive
systems, it is critical that air is purged from the sys-
tems.
The resulting symptoms of air in the hydrostatic sys-
tems may be:
1. Noisy operation.
2. Lack of power or drive after short term opera-
tion.
3. High operation temperature and excessive
expansion of oil.
* (If starting here, Follow numbers 1-4 of the pro-
ceeding page before continuing).
21. Engage neutral bypass valves.
22. Start engine and idle up to 1800 rpm. Disengage
parking brake.
23. Slowly move the directional controls in both for-
ward and reverse directions (5 or 6 times).
24. Release bypass valves.
25. Again, slowly move the directional controls in
both forward and reverse directions (5 to 6 times).
26. Stop engine. Engage parking brake. Check the oil
level, and add oil as required.
27. It may be necessary to repeat Steps 22 thru 26
until all the air is completely purged from the sys-
tem.
28. Re-install skid plate.
29. Re-install rear tires and lower machine.

the transaxle operates at normal noise levels and
moves smoothly forward and reverse at normal
speeds, then the transaxle is considered purged.
If necessary, repeat the purge procedure.
