Snapper uv1621bv Manual Do Utilizador

21 

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.
