4. If the oil level is low, remove the filler cap from the valve cover and pour oil into the opening in the valve cover until the oil level is up to the Full mark on the dipstick. Add the oil slowly and check the level often during this process. Do not overfill. DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.
Checking the Hydraulic Fluid Level Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 2/3 oz. (20 ml) bottles. One bottle is sufficient for 4-6 gal (15-22 1) of hydraulic oil. Order part no. 44-2500 from your authorized Toro distributor. This red dye is not recommended for use with biodegradable fluids. Use food coloring. The hydraulic fluid reservoir is filled at the factory with approximately 4.5 U.S.
4. Move the choke lever to the On position (only when starting a cold engine) and the throttle lever to the half throttle position. Vary the tire pressure for the rear wheel from a minimum of 8 psi to a maximum of 15 psi (55 to 103 kPa). 5. Insert and rotate the ignition key clockwise until the engine starts. After the engine starts, regulate the choke to keep the engine running smoothly. As soon as possible, open the choke by pulling it rearward to the Off position.
Checking the Safety Interlock System CAUTION 3. If the safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.
Before Mowing traction shift selector is in the #1 and #2 positions with the parking brake engaged. Inspect the green for debris, remove the flag from the cup, and determine the best direction to mow. Base the direction to mow on the previous mowing direction. Always mow in an alternate pattern from the previous mowing so that the grass blades will be less apt to lay down and therefore be difficult to trap between the reel blades and bedknife.
the direction of mowing from the previous cutting. Replace the flag. 7. Raise the cutting units and empty the grass baskets of all clippings before transporting to the next green. Heavy wet clippings place an undue strain on the baskets and will add unnecessary weight to the machine, thereby increasing the load on the engine, hydraulic system, brakes, etc. Transport Operation Make sure the cutting units are in the full up position. Set the shift selector in No.
