Maintenance Instructions
2. Use a pressure washer or water spray, and
direct the spray inside the blower housing
against the blower blades. Water pressure will
cause the blower wheel to begin to spin, and the
combination of spinning action and water will
effectively wash the inside of the housing. Spray
may be directed against the blower blades ver-
tically and horizontally to cause rotation in both
directions for thorough washing action. Wash
blower until the blower wheel spins freely in
both directions.

Hydrostatic Transmission Cooling Fins

Keeping the cooling fins on the hydrostatic transmis-
sions clean and free of obstruction is essential to
avoid overheating the transmission fluid and short-
ening transmission life. The cooling fins should be
checked every 100 hours; and cleaned if
necessary.
To clean the fins, use compressed air and/or a pres-
sure washer. The cooling fins extend all the way
around the housing -- the fins underneath need to be
clean as well as the more visible fins above. Also,
pay close attention to the area under the drive pulley.
IMPORTANT: In case an oil leak develops on the
input shaft, the cooling fan blowing dusty air and oil
on the transmission will quickly pack the cooling fins
with oily dirt. If this condition occurs, replace the
seal immediately to avoid overheating and damag-
ing the transmission. The input shaft assembly and
seal are easily replaced without removing the trans-
mission from the machine.
An additional procedure in maintaining transmission
cooling is to inspect the cooling fans. Replace the
fan(s) if blades are missing or damaged.
