Before turning on the machine each day, perform the following procedures:

• Check the reel-to-bedknife contact; refer to Checking the Reel-to-Bedknife Contact.

• Check the tire pressure; refer to Checking the Tire Pressure.

• Check the safety-interlock system; refer to Checking the Safety-Interlock System.

• Check the parking brake function by actuating the parking brake and ensuring that it engages; refer to Parking Brake.

8 hours of operation is required for the break-in period.

Since the first hours of operation are critical to future dependability of the machine, monitor its functions and performance closely so that minor difficulties, which could lead to major problems, are noted and can be corrected. Inspect the machine frequently during break-in for signs of loose fasteners or any other malfunction.

Note: Inspect the areas beneath the cutting units to ensure that they are clear of debris.

1. Sit in the operator’s seat and fasten the seatbelt.

2. Insert the key into the switch and move it to the ON position.

1. Move the function-control switch to the MOW position.

2. Disengage the parking brake.

3. Move the lift/lower joystick forward momentarily.

   The cutting units should lower and all the reels should rotate.

4. Move the lift/lower joystick rearward.

   The cutting reels should stop rotating and the cutting units should raise to the full transport position.

The purpose of the safety-interlock system is to prevent operation of the machine where there is possible injury to you or damage to the machine.

The safety-interlock system prevents the machine from moving unless:

• The parking brake is disengaged.

• You are seated in the operator's seat.

• The function-control switch is in the MOW position or the TRANSPORT position.

Additionally, the safety-interlock system prevents the reels from operating unless the function-control switch is in the MOW position (except when the machine is in Backlap Mode).

• Ensure that the cutting units are fully raised.

• Sit in the seat, fasten the seat belt, disengage the parking brake, and move the function-control switch to the TRANSPORT position to drive the machine without mowing.

• Always approach irregular areas at a reduced speed and cross severe undulations carefully.

• Familiarize yourself with the width of the machine. Do not attempt to pass between objects that are close together to prevent costly damage and downtime.

Before mowing greens, find a clear area and practice performing basic machine functions (e.g., turning on and stopping the machine, raising and lowering the cutting units, and turning).

Inspect the green for debris, remove anything that may damage the cutting units while mowing, 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 are less apt to lay down and will have a greater chance of being cut.

Refer to the main information screen in the InfoCenter to determine the battery-system charge level; refer to Using the InfoCenter Display.

1. Transport the machine to a level surface.

2. Move the function-control switch to the NEUTRAL position.

3. Engage the parking brake.

4. Rotate the key to the OFF position to shut off the machine.

5. Remove the key.

After mowing, thoroughly wash the machine with a garden hose without a nozzle so that excessive water pressure does not contaminate and damage the seals, bearings, and electronics. Do not wash the electrical connections with water.

Important: Do not use brackish or reclaimed water to clean the machine.

Important: Do not use power-washing equipment to wash the machine. Power-washing equipment may damage the electrical system, loosen important decals, or wash away necessary grease at friction points. It may force water under seals, contaminating oil or grease contained housings. Avoid excessive use of water near the control panel and batteries.

Inspect the cutting units for sharpness after you clean the machine.

• Use care when loading or unloading the machine into a trailer or a truck.

• Use a full-width ramp for loading the machine into a trailer or a truck.

• Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine (Figure 36).

To tow the machine, you must perform the following procedure to release the brake actuator:

1. Engage the parking brake.

2. Remove the key and disconnect the main-power connectors.

   Important: If the main-power connectors are connected while towing, electrical damage may result.

3. If the 3-Wheel Drive Kit is installed, disconnect the kit-wire-harness connectors from the main wire harness.

   Important: If the kit and machine wire harnesses are connected while towing, electrical damage may result.

4. Chock both sides of the front tires.

5. Release tension on the spring by loosening the nut that secures the eyebolt to the spring bracket (Figure 37).

6. Remove the spring.

7. Insert a ratchet (3/8 inch) through the hole of the arm bracket and push in the actuator shaft.

   Danger

   When the actuator is released from the brake, the machine is able to free wheel. A free-wheeling machine can cause serious injury to bystanders.

   If the machine is not being towed, engage the parking brake.

8. Have an assistant sit in the seat, fasten the seatbelt, and use the brake while you tow the machine.

   Note: This ensures that the machine is under control when you tow the machine.

9. Remove the chocks from the tires.

10. When the machine is ready to be towed, disengage the parking brake.

11. Use the rear castor fork to tow the machine (Figure 38).

    Important: Do not exceed 5 km/h (3 mph) while towing the machine. Damage to the electrical components may result.

    

    Figure 38

    1. Rear castor fork

After you have towed the machine to your intended destination, perform the following steps:

1. Engage the parking brake.

2. Remove the tow strap from the castor fork.

3. Install the spring as shown in Figure 37.

4. Tighten the eyebolt nut so that the spring length is 11.4 cm (4.5 inches) when installed (Figure 37).

The lithium-ion batteries hold a sufficient charge to perform intended work during its life span. During the first 4 years of operation, the total area that you can cut per a single full charge is 13,006 m² (140,000 ft²). This performance is based on the following conditions:

• Your reel blades and bedknives are sharp.

• The bedknife and reel contact is adjusted per the Operator's Manual.

• The groomer is set at half of the height of cut or higher.

• The rear roller brushes are set to the lightest contact.

• 8 miles of transport distance is needed.

• The golf course that you perform work on is lightly undulated.

As time goes by, the total amount of work that the batteries are able to complete on a single charge gradually diminishes.

Note: Your results may vary depending on the distance that you need to transport the machine, the undulations that you travel across, the contact setting and sharpness of the bedknife and reel, and other factors as discussed in this section.

To achieve maximum life and use from your batteries, follow these guidelines:

• Do not open the battery.

• Store/park the machine in a clean, dry garage or storage area, away from direct sunlight, heat sources, rain, and wet conditions. Refer to Battery Storage Requirements for temperature requirements.

• If you are mowing in hot conditions or in sunlight, the battery may overheat. If this happens, a high-temperature alert will appear on the InfoCenter. In this condition, the cutting units are disengaged and the machine slows down.

  Immediately drive the machine to a cool location out of the sun, turn off the machine, and allow the batteries to cool fully before resuming operation.

• Adjust the reel-to-bedknife contact to be as light as possible. This reduces the power that is needed to run the cutting units, and increases the amount of work the machine performs on each charge. Refer to Checking the Reel-to-Bedknife Contact.

• Ensure that the sharpness of the bedknives and reels are maintained. A dull blade increases power consumption and reduces the amount of work that the machine performs on each charge.

• If you are using groomers, the groomer height should not exceed more than half of the height of cut. If the height of cut is over 1/2 inch, the groomer height should not exceed 1/4 inch.

• Adjust the rear-roller-brush contact to be as light as possible. This reduces the power that is needed to run the cutting units, and increases the amount of work the machine performs on each charge.

• Use lights (if your machine is equipped with the Light Kit) only when it is necessary.

The US Department of Transportation and international transportation authorities require that lithium-ion batteries be transported using special packaging and only be transported by carriers certified to haul them. In the US, you are allowed to transport a battery when it is installed on the machine as battery powered equipment, with some regulatory requirements. Contact the US Department of Transportation or the appropriate government body in your country for detailed regulations on transportation of your batteries or the machine with the batteries equipped.

For detailed information on shipping a battery, contact your authorized Toro distributor.
