ery 400 hours of operation as follows:
1. Thoroughly clean the exterior of the transmis-
sion housing before servicing. Remove expan-
sion tank cap to allow venting. Using a 1/4 in.
hex wrench, remove the plug on the lower in-
side of each transaxle allowing the oil to drain.
Remove the oil filter guard, remove and replace

7. If the transaxles sound noisy or have poor steer-
ing response, there may be air trapped in the
transaxles. Follow purge instructions below.
8. If oil needs to be added refer back to steps 4-7.
9. To purge air from transaxle, raise unit and block
with tires off the ground. With engine running,
slowly move Forward Speed Control forward
and backward 5 to 6 times. Turn off engine and
check oil level and add if needed. Repeat pro-
cedure until transaxle operates at normal noise
levels and move smoothly in forward and re-
verse.
