56Maintenance Instructions CLEANING/CHECKING/SERVICINGHydrostatic Transmission Cooling FinsKeeping the cooling fins on the hydrostatic transmis-sions clean and free of obstruction is essential toavoid overheating the transmission fluid and short-ening transmission life. The cooling fins should bechecked every 100 hours; and cleaned if neces-sary.To clean the fins, use compressed air and/or a pres-sure washer. The cooling fins extend all the wayaround the housing -- the fins underneath need tobe 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 theinput shaft, the cooling fan blowing dusty air and oilon the transmission will quickly pack the coolingfins with oily dirt. If this condition occurs, replacethe seal immediately to avoid overheating and dam-aging the transmission. The input shaft assemblyand seal are easily replaced without removing thetransmission from the machine.An additional procedure in maintaining transmissioncooling is to inspect the cooling fans. Replace thefan(s) if blades are missing or damaged.CoolingFinsCoolingFansHydrostatic Transmission Cooling FinsCHECKING/SERVICINGDANGERTo prevent accidental starting of the en-gine when servicing or adjusting the ma-chine, remove the key from the ignitionswitch and disconnect the spark plug wire.Security of Air Filtration ComponentsNOTE: The following inspection is only an externalinspection 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 Donaldson Radialseal™ air cleanercanister for damage. Make sure the cover is inplace and the cover latches are secure - do notrun the engine without the air cleaner cover inplace and secure.2. Inspect the air intake hose for cracks, nicks,cuts, etc., and check the hose clamps for tight-ness.3. Check to make sure the air flow indicator is inplace and tight.BatteryNOTE: For initial battery service during setup, referto Battery Service in Assembly Instructions.IMPORTANT: Make sure battery is securely mount-ed in the frame. A loose battery may cause damageto the case resulting in acid leakage and severe dam-age to the machine. A hazard may be created bydamage to critical working parts and safety systems.Electrolyte LevelThe 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 belowthe 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].
