Maintenance Instructions LUBRICATION47Gear Axle Lubrication• The gear axle oil lubrication is SAE 80W-90 (APIGL-5) gear lube.• Check the axle oil level after every 100 hours ofoperation by removing the oil level plug. If additionaloil is needed, remove the breather vent on top of ax-le and fill until oil is at the level plug.• Change axle oil every 1000 hours or two (2)years.Hydrostatic Transmission FluidChecking Hydrostatic Transmission Fluid LevelHydrostatic transmission fluid level should bechecked every 25 hours of machine operation. It ispreferable to check the fluid level when fluid iscold. Check fluid level as follows:1. Park the mower on a level surface. Stop theengine and wipe dirt and contaminants fromaround the reservoir cap and air bleed plug.IMPORTANT: Before removing the reservoircap, clean any dirt from around it. Any dirt orcontaminants entering the transmission willaccelerate wear and eventually cause loss ofpower to the drive wheels.2. Remove the reservoir cap and check the level ofthe fluid. The reservoir has a fluid level COLDmark and HOT mark. The reservoir oil levelshould ALWAYS be at or above the COLDmark and NEVER above the HOT mark.3. If the fluid is below the COLD mark (or the trans-mission is not performing properly), loosen theair bleed plug (located on the top of transmis-sion case next to the plastic reservoir).a. If a small amount of fluid leaks from aroundthe air bleed plug:* The transmission is full of fluid.* Tighten the plug and fill the reservoir tothe COLD level mark.b. If no fluid leaks from around the air bleedplug:* Slowly add fluid into the reservoir untilfluid starts to leak from around the plug.(Transmissions are serviced from thefactory with Mobil DTE 18M hydraulicoil. When it is necessary to add fluid,refer to Specifications for the proper flu-id. Use any of the fluids listed.)* As soon as there is fluid leaking fromaround the air bleed plug, tighten theplug and fill the reservoir to the COLDlevel mark. Wipe any excess oil off ofthe transmission housing.Transmission Reservoirand Air Bleed Plug LocationIMPORTANT: DO NOT overfill the transmissionreservoir. This will result in oil leaking out of the res-ervoir cap vent when the transmission warms up. Itis preferable to add fluid to the transmission when itis cold and make sure the oil is not above or be-low the COLD level mark.IMPORTANT: The transmission reservoir has a finemesh screen in the bottom to trap dirt and foreignparticles from entering the transmission. When fillingthe reservoir, fluid will flow quite slowly through thisscreen; so it is essential that there is fluid at the bleedplug before the transmission is considered full.IMPORTANT: Any attempt to remove or in any wayalter the filtering screen in the transmission reservoircould cause damage to the transmission and willVOID any transmission warranty.Reservoir CapHot LevelCold LevelAir BleedPlug
