CHECKING/SERVICING
Transaxle Cooling Fins
Keeping the cooling fins on the transaxles clean and
free of obstruction is essential to avoid overheat-
ing the transmission fluid and shortening
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, contact your
dealer immediately to avoid overheating and dam-
aging the transaxle.
An additional procedure in maintaining transaxle
cooling is to inspect the cooling fans. Replace the
fan(s) if blades are missing or damaged.

CHECKING/SERVICING
Security of Air Cleaner System
NOTE: The following inspection is only an external
inspection and should be done without “disturb-
ing” the filtration components.
On a daily basis, visually inspect the external condi-
tion of the air cleaner cover.
Check for damage. Make sure the cover is in place
and the cover latches are secure - do not run the
engine without the air cleaner cover in place and
secure.
Battery
NOTE: For initial battery service during setup, refer
to Battery Service in
Assembly Instructions .
IMPORTANT: Make sure battery is securely
mounted in the frame. A loose battery may cause
damage to the case resulting in acid leakage and
severe damage to the machine. A hazard may be
created by damage to critical working parts and
safety systems.
Cleaning the Terminals
If battery terminals are corroded, remove battery
from the mower. Using a wire brush, remove corro-
sion with a solution of one part baking soda and
four parts water. Rinse with clean water. Coat the
terminals with petroleum jelly or terminal protector
spray to retard further corrosion.
Charging the Battery
DANGER
To prevent accidental starting of the en-
gine when servicing or adjusting the ma-
chine, remove the key from the ignition
switch and disconnect the spark plug
wires.

DANGER
BATTERIES PRODUCE EXPLOSIVE
GASES
•
Charge the battery in a well-ventilated
area, so that gases produced while charg-
ing can dissipate.
•
Keep sparks, flames, and smoking ma-
terials away from the battery at all times.
•
Make sure the battery cap vents are open
(check manifold vent on each cap).
•
Make sure the battery charger is un-
plugged before connecting or discon-
necting cables to the battery.
