CHECKING/SERVICING

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 dam- aging 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 en- gine 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 exter- nal inspection and should be done without “dis- turbing” the filtration components.

On a daily basis, visually inspect the external condi- tion of the complete air cleaner system. The follow- ing items should be inspected:

1.Check the security of the engine air cleaner cover and inspect it for damage and make sure it seals properly with the engine baseplate. Im- proper sealing may be caused by a bent base- plate.

2.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.

3.Inspect both air intake hoses for cracks, nicks, cuts, etc., and check the hose clamps for tight- ness.

Battery

NOTE: For initial battery service during setup, re- fer to Battery Service in Assembly Instructions.

Electrolyte Level

The battery electrolyte level should be checked af- ter every 25 hours of operation. To check electro- lyte 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].
