Do not pressure wash the damaged or worn, replace it immediately with a machine. Avoid excessive use of water, especially genuine Toro replacement blade. Refer to Servicing near the control panel, under the seat, around the the Cutting Blades (page 40).
Pushing the Machine by Hand This machine has an electric-brake mechanism, and to push the machine, the key must be in the position. The battery needs to be charged and functioning to disengage the electric brake. Park the machine on a level surface, disengage the blade-control switch, and move the motion-control levers outward to the P position.
Transporting the Machine Use a heavy-duty trailer or truck to transport the machine. Use a full-width ramp. Ensure that the trailer or truck has all the necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you or bystanders avoid injury.

If you are using a trailer, connect it to the towing vehicle and connect the safety chains. If applicable, connect the trailer brakes and lights. Lower the ramp, ensuring that the angle between the ramp and the ground does not exceed 15 degrees (Figure 26).
Disconnect the cable from the negative terminal of the battery before repairing the machine. • To ensure optimum performance, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty.

While the exposure from Toro products may be negligible or well within the “no significant risk” range, out of an abundance of caution, Toro has elected to provide the Prop 65 warnings. Moreover, if Toro does not provide these warnings, it could be sued by the State of California or by private parties seeking to enforce Prop 65 and subject to substantial penalties.
