SECTION 3 – MAINTENANCE
3.2.8.Check Interlocks
The machine is equipped with interlocks that prevent the engine from cranking or starting unless the brake is fully depressed and the transmission is in Neutral. It is also equipped with an operator presence sensor that will cause the engine to die if the operator attempts to leave the seat without setting the park brake. On models equipped with the POWERLINK Generator System, the interlock kills the engine if the parking brake is disengaged or the transmission is engaged while the generator is being operated. The interlocks were designed for the safety of the operator and others. Do not modify or defeat the interlocks. Do not operate the machine if interlocks are not functioning properly.
