TRANSAXLE COOLING
The transmission fan and cooling fi ns

damage to seals, do not use high pres sure
water or steam to clean transaxle.
• Inspect cooling fan to be sure fan blades
are intact and clean.
• Inspect cooling fi ns for dirt, grass clip-
pings and other materials. To prevent
damage to seals, do not use com-
pressed air or high pressure sprayer to
clean cool ing fi ns.
