Operation Adding Fuel Note: Determine the left and right sides of the machine from the normal operating position. Fuel Specification • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). Before Operation • Ethanol: Gasoline with up to 10% ethanol Before Operation Safety (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same.
Understanding the Safety Interlock System The safety interlock system prevents the engine from starting unless the traction bail is in the NEUTRAL position. Testing the Safety Interlock System Service Interval: Before each use or daily 1. If running, shut off the engine. 2. While holding the traction bail forward or backward, start the engine. g010026 Figure 15 The engine should not start. 1. Fuel-tank cap 3. Move the traction bail to the and start the engine. 3. 4.
• Before starting a cold engine, move the • Stop the machine, shut off the engine, remove the key, wait for all moving parts to stop, and inspect the tines after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation. • • Always maintain proper tire pressure. • Reduce traction speed on rough roads and choke control to the ON position. When starting a warm or hot engine, you may not need to use the choke. 3.
Using the Line Marker Walk in a forward direction while operating the machine, do not walk and face rearward when operating the machine. 5. Engage the PTO and lower the coring head. 6. Disengage the PTO and raise the coring head. 7. To stop the machine, release the traction bail. Use the line marker to align aeration rows (Figure 17). Setting the Coring Depth 1. Park the machine on a level surface, shut off the engine, engage the parking brake, and remove the key. 2.
g010036 Figure 18 1. Service latch in (lowered) storage position g010043 4. Figure 20 Pivot the service latch rearward and insert it onto the coring head pin (Figure 19). Secure the latch with the clip ring. 1. Lynch pin 3. 2. Spacers and depth pin Position the spacers above or below the bracket to attain the desired coring depth. • Thick spacers equate to 19 mm (3/4 inch) increments. • Thin spacer equates to 9.5 mm (3/8 inch) depth increment.
Installing Tine Holders, Turf Guards, and Tines 5. Loosely install a tine clamp to each tine holder (Figure 24) with 4 bolts (3/8 x 1-1/2 inches). Do not tighten the bolts. A wide selection of tine holders, turf guards, and tines are available for the machine. Choose the required components per the accessory chart in Attachments and Accessories. 1. Raise the coring head and lock it in position with the service latch. 2.
1. Park the machine on a level surface, shut off the engine, engage the parking brake, and remove the key. 2. Loosen the carriage bolt nuts securing the spring brackets to the coring head (Figure 27). Do not remove them. g010042 Figure 26 1. Gaps in the turf guards 8. Install the remaining tines into the #1, 3, 4, and 6 tine holders. Torque all tine holder bolts to 40.6 N∙m (30 ft-lb). g010051 Replacing Tines Figure 27 1.
Adding Additional Weight 4. With the increased weight transfer, it is possible to aerate firm enough ground that the weight transfer begins to lift the rear 2 tires off the ground. This may lead to irregular hole spacing. Disengage the parking brake before pushing/pulling the machine. Important: Do not operate the engine with the bypass valve open for more than 10 to 15 seconds. 5. If this occurs, you can add an additional weight plate to the rear frame axle tube. Each cast weight adds 28.
Moving the Machine when the Coring Head is Lowered and tees, the deeper depth and longer hollow tines may have difficulty ejecting the complete core. This is due to harder native soil that sticks in the end of the tine. Side-eject greens/tees tines from Toro stay cleaner and reduce the time required to clean the tines out. You will eventually eliminate this condition with continued aeration and top-dressing programs.
Adjusting the #4 Proximity Switch The #4 proximity switch is by default positioned at the lowest setting, allowing for improved entry hole performance and depth; switch #4 should be assembled in the lowest position during most aeration activities. If aerating at a shallow depth causes the coring head to overshoot the tine depth, or if you are experiencing coring head bounce, adjust the #4 proximity switch to a higher setting on the H-bracket when aerating at shallow depths (Figure 32).
Important: If the coring head fails to start before entrance and the position switch is located as high as permissible, the electric clutch may have deteriorated sufficiently to cause a delay in engagement. Contact your authorized Toro distributor or refer to the Service Manual. Mini Tine (Quad Tine) Because of the double row design, the mini-tine coring head requires the hole spacing to be set at 6.3 cm (2-1/2 inches). Ground speed is critical to maintain the appearance of 3.
Locating the Tie-Down Points Hauling the Machine WARNING There are tie downs located at the front and rear sides of the machine (Figure 33, Figure 34, and Figure 35). Driving the machine on street or roadway without turn signals, lights, reflective markings, or a slow-moving vehicle emblem is dangerous and can lead to accidents causing personal injury. Note: Use properly-rated DOT-approved straps to tie down the machine. Do not operate the machine on a public street or roadway.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Maintenance Safety • Perform only those maintenance instructions CAUTION If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. • • Engage the parking brake, shut off the engine, remove the key, and secure the coring head with the service latch before servicing or adjusting to the machine.
