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, disengage the parking brake, and move the function-control switch to the TRANSPORT position to drive the machine without mowing.

• Always approach rough 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., starting 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.

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 a warm engine or 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, engine, and battery.

Important: Do not wash the machine with the engine running. Washing the machine with the engine running may result in internal engine damage.

Important: Do not force water into the muffler. Water inside the muffler may result in internal engine damage or reduced engine performance.

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 32).
