Before Operating ACTIVATE AND CHARGE THE BATTERY 1. Since the battery is not filled with electrolyte or activated, bulk electrolyte with 1.260 specific gravity must be purchased from a local battery supply outlet. WARNING Electrolyte gases are explosive and can cause serious injury to eyes, lungs and skin. Wear safety goggles and rubber gloves when working with electrolyte or the battery. Charge the battery in a well-ventilated place so gasses produced while charging can dissipate.
tive (-) terminal of the battery and secure with capscrews and nuts. Slide the rubber boot over the positive terminal to prevent possible short-out (Fig. 2). 9. Lower the hood and secure the latches. CHECK THE ENGINE OIL The Onan engine is shipped with 3 quarts of oil in the crankcase; however, the oil level must be checked before and after the engine is first started. 1. Position the machine on a level surface. 2. Unscrew the dipstick and wipe it with a clean cloth.
REDUCING THE BUILD-UP OF COMBUSTION CHAMBER DEPOSITS. DANGER Because fuel is flammable, caution must be used when storing or handling it. Do not fill the fuel tank while the engine is running, hot or when the machine is in an enclosed area. Vapors may build up and be ignited by a spark or flame source many feet away. DO NOT SMOKE while filling the fuel tank to prevent the possibility of an explosion. Always fill the fuel tank outside and wipe up any spilled fuel before starting the engine.
Mobil DTE 26 hydraulic oil. Check the level of hydraulic oil on the sight gauge before the engine is first started and daily thereafter. Change the filter initially after 25 hours of operation, thereafter change the oil and filter every 250 hours of operation. The oil and filter must be changed immediately when any contamination, sludge, water or condensation appears in the oil or on sight gauge. Determine and correct oil contamination problem before restarting the engine and operating the machine. 1.
CHECK TIRE PRESSURE Tires are over inflated for shipping. Make sure the front and rear tires are inflated to 55–82 psi. CHECK THE ACCUMULATOR CHARGE Have the accumulator charge checked before and after each operating season by an Authorized TORO Distributor. WARNING Charged accumulators contain high-pressure nitrogen. Nitrogen is the only gas to use for accumulator charing. Installing Improper gasses in an accumulator can cause an explosion and death. Charging requires special tools and precautions.

Operation OPERATING PRECAUTIONS 1. 2. 3. Before aerating, inspect the work area for debris and determine the best direction and pattern in which to operate the machine. If the machine starts to vibrate abnormally, shut off the engine. Remove the wires from the spark plugs to prevent possible accidental starting. Check the machine for damage and defective parts. Repair any damage before restarting the engine and operating the machine. Use only in daylight or when there is good artificial light.
dence in the performance of the Hydroject 3000. OPERATING PROCEDURE 1. Make sure the wires are installed on the spark plugs and the fuel shut-off valve is open. 2. Uncoil a garden hose making sure there are no kinks or bends in the hose. Lay out the hose so there are no obstructions between the machine and the area to be aerated. Turn on the water supply to purge any air from the hose. Turn off the water. 3. Connect the hose adapter (Fig.
Note: Injection operation starts approximately 4–5 seconds after pump engages. Also, the injection system will automatically stop if the traction bail is not engaged within 3–4 seconds after starting the water system. 11. When aerating, work moving perpendicular from the water supply to avoid running over the garden hose. Use front edge of the hood or rear corner of frame to align rows, if desired. When at the end of a row, make a "S" maneuver and reverse direction of aerator.
CAUTION THE INTERLOCK SWITCHES ARE FOR THE OPERATOR’S PROTECTION, SO DO NOT DISCONNECT THEM. CHECK SWITCH OPERATION DAILY TO ASSURE THE INTERLOCK SYSTEM IS OPERATING. IF A SWITCH IS DEFECTIVE, REPLACE IT BEFORE OPERATING THE MACHINE. REPLACE THE SWITCHES EVERY TWO YEARS TO ASSURE MAXIMUM SAFETY. DO NOT RELY ENTIRELY ON SAFETY SWITCHES—USE COMMON SENSE! To do a functional check of the interlock system: 1. Position the machine in a flat, open area on rough turf away from buried wires, plumbing, etc.
push the aerate ENGAGE button to begin aerating. Push the aerate DISENGAGE button. The water pump should disengage immediately, then stop aerating after 3 seconds. If the machine does not stop aerating, there is a malfunction in the interlock system that must be corrected. Note: Lights (LED's) on the controller (Fig. 12) indicate when the following inputs are made to the controller: Red: Transport switch closed (traction bail in neutral). Figure 12 Green: Aerate start (engage) switch closed.
