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.
