4.2 SAFETY INTERLOCK SYSTEM

This mower is equipped with a safety system that prevents the engine from starting unless the mower blade brake is disengaged and parking brake is engaged. The system also shuts the engine off if the operator's left foot is raised from the interlock pedal with the mower and parking brakes disengaged.

WARNING:

Never operate the mower with the interlock system disconnected or malfunctioning. Do not disconnect or bypass any switch; injury to yourself and others or property damage could result.

If the safety interlock system is malfunctioning or if you want to ensure that it is working properly, perform the tests in Table 4-1. Stop the test and have the system inspected and repaired if:

•the engine does not start in test 1, or

•the engine does start during tests 2 and 3, or

•the engine continues to run during tests 4 and 5.

4.3INITIAL RUN-IN PROCEDURES (First Day of Use or Approximately 10 Hours)

3.Check the tires for proper inflation (See Section 7-2).

4.Check for loose hardware. Tighten as needed.

5.Perform Interlock Tests in Table 4-1.
