Hydrostatic Transmission Cooling Fins

Keeping the cooling fins on the hydrostatic transmissions clean and free of obstruction is essential to avoid overheating the transmission fluid and shortening transmission life. The cooling fins should be checked every 100 hours; and cleaned if neces- sary.

To clean the fins, use compressed air and/or a pressure 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 pul- ley.

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 damaging the transmission. The input shaft assembly and seal are easily replaced without removing the transmission 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.

CHECKING/SERVICING

DANGER

To prevent accidental starting of the engine when servicing or adjusting the ma- chine, remove the key from the ignition switch and disconnect the spark plug wires.

Security of Air Filtration Components

NOTE: The following inspection is only an external inspection and should be done without “dis- turbing” the filtration components.

On a daily basis, visually inspect the external condition 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 tight- ness.

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 wa- ter to the bottom of the vent wells [1/4 to 1/2 in. (6 to 13 mm) above the plates].

3.Replace filler caps.
