ATTENTION
Damage to the machine from incorrect operation
The
UP
button has to be pressed, as this control is used to bypass the
EMERGENCY
limit switch. If the rotary knob is activated inadvertently, the
motor brake is released and the motor can drop hard onto the foot section.
After neutral running, disconnect the drop test control and plug in the
dummy plug.
If this problem occurs repeatedly despite the platform not being
overloaded, have the brake checked or adjusted by a qualified
person.
