This generally involves the inside the tiller head that reads the angle at which the operator is holding the handle (the zero-travel, acceleration, or neutral zones). Because the system cannot verify the physical position of the tiller arm, it triggers a safety lockout to prevent erratic, uncontrolled movements of the pallet jack. The Root Causes of Error 4372
