7.3.14.6 M13 microswitch (oscillating axle)
The M13 microswitch checks the position of the oscillating axle and is located on the chassis, above the oscillating axle.
Its function is:
When the platform is lifted (the oscillating axle locks in the position it was before lifting) if the two wheels of the oscillating axle
are not on the same ideal plane as those of the fixed axle (within an allowance of about 50mm), drive is prevented (this
condition is signalled by the danger red light at platform - the alarm is not activated).
