Fill Port - Insert rod through this port
to check fluid level.
Void Air Space - 1-78”
Correct Fluid Level - 4-1/4”
IMPORTANT
When tightening the filter insure proper torque
value of 20 - 50 in. lbs. is applied. Filter is plas-
tic. Excessive torque will damage filter.
Due to the effects air has on eficiency in the hydro-
static drive applications, it is critical that it be purged
from the system.
These purge procedures should be implemented
any time a hydrostatic system has been opened to
facilitate maintenance or any additional oil has been
added to the system.
Air creates inefficiency because its compression and
expansion rate is higher than that of the oil normally
approved for use in hydrostatic drive systems.
The resulting symptoms in hydrostatic systems may be:
!. Noisy operation.
2. Lack of power or drive after short term operation.
3. High operation temperature and excessive expan-
sion of oil.
Before starting, make sure the transaxle/ transmis-
sion is at the proper oil level. If it is not, fill to the
specifications outlined above.
PURGING PROCEDURES
The following procedure should be performed with
the vehicle wheels off the ground, then repeated
under normal operating conditions.
1. With the bypass valve open and the engine run-
ning, slowly move the directional control in both for-
ward and reverse directions 5 or 6 times. As air is
purged from the unit, the oil level will drop.
2. With the bypass valve closed and the engine
running, slowly move the directional control in both
forward and reverse directions (5 to 6 times). Check
the oil level, and add oil as required after stopping
engine.
3. It may be necessary to repeat Steps 1 and 2
until all the air is completely purged from the system.
When the transaxle moves forward and reverse at
normal speed, purging is complete.
PARKING BRAKE ADJUSTMENT
The parking brake has been set correctly from the
factory. Occasionally check the parking brakes and
adjustment using the following method:
1. Position the control levers in the neutral position.
2. Disengage the hydrostatic transaxle by
pulling out and locking the bypass levers.
3. Move the parking brake lever to the brake position.
4. The brake pawl should now be activated and
engaging the hydrostatic components brake
gear.
5. Move the parking brake lever down to disen-
gage the brake. Standing behind the unit, the
mower should be able to be pushed around
freely.
6. If the brakes do not operate correctly, the cable
must be adjusted. To adjust the brake cables,
loosen the two locknuts on the spring end of
the cables, just to the inside of each of the rear
tires. Adjust the cables up or down the thread-
ed adjustment until the brake pawl is fully
engaging the brake gear when the brake is
engaged and the spring is slightly extended
and the brake pawl is fully disengaging the
brake gear when the brake lever is disengaged.
7. Tighten the locknuts securely.
