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.

Security of Air Filtration Components
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 complete air cleaner system. The
following items should be inspected:
1. Check the Donaldson Radialseal™ air cleaner
canister 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.
2. Inspect the air intake hose for cracks, nicks,
cuts, etc., and check the hose clamps for
tightness.
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.
Electrolyte Level
The battery electrolyte level should be checked after
every 25 hours of operation. To check electrolyte
level:
1. Remove battery cell filler caps.
2. Check the electrolyte level. If the level is below
the bottom of the vent well, fill with drinking
water to the bottom of the vent wells [1/4 to 1/2
in. (6 to 13 mm) above the plates].
