Shut off the engine, wait for it to cool, and cleanthe area around the oil-filler cap/dipstick (Figure17).g024013Figure 171. Oil-filler cap/dipstick 2. Filler port3. Remove the oil-filler cap/dipstick by rotating itcounterclockwise.4. Wipe the oil-filler cap/dipstick clean and insert itinto the filler port.Note: Do not screw the dipstick into the port.5. Remove the dipstick and check the oil level.Note: If the oil level is near or below thelower-limit mark on the dipstick, add only enoughoil to raise level to the upper-limit mark (bottomedge of the oil-fill hole); refer to Figure 18. Checkthe oil level again. Do not overfill the crankcase.g024239Figure 181. Upper limit 2. Lower limit6. Install the oil-filler cap/dipstick and wipe up anyspilled oil.Note: Running the engine with the oil level at thelower limit may induce nuisance engine shutdowns inoperating situations where the machine is switchingdirection on an incline or descent.Checking the Level of theHydraulic FluidService Interval: Before each use or dailyThe hydraulic system is filled at the factory withhigh-quality hydraulic fluid. Check the level of thehydraulic fluid before the engine is first startedand daily thereafter.Note: Before working on any part of the hydraulicdrive system, shut off the engine to depressurize thesystem. Before starting the engine after hydraulicsystem maintenance, and pressurizing the hydrauliclines, check all hoses and connectors for damage andto ensure that they are tight. Replace any damagedhoses and tighten any loose couplings as required.Recommended Hydraulic Fluid: Toro Premium AllSeason Hydraulic Fluid (Available in 5 US gallonpails or 55 US gallon drums. Refer to the parts catalogor contact your Authorized Toro Distributor for partnumbers.)Alternative fluids: If the Toro fluid is not available,other conventional, petroleum-based fluids may beused, provided they meet all of the following materialproperties and industry specifications. Check withyour oil supplier to see whether the oil meets thesespecifications.Note: Toro will not assume responsibility for damagecaused by improper substitutions, so use onlyproducts from reputable manufacturers who will standbehind their recommendation.15
