1. Control Circuits and Power Circuits
Most control circuit problems show up as a contactor failing to
close at the proper time. Most power circuit problems show
up as the truck failing to travel or lift after the proper contactor
has closed. The tests that follow instruct the technician to test
the voltage at various components at particular times during
truck operation. All voltage tests are made with the negative
lead of the test meter connected to battery negative. At no
time should the frame of the truck be connected to either
battery positive or battery negative.
The functions should be adjusted to the following values:
* These functions control the speed of the truck when raised.
The function should be adjusted to the prescribed setting and
then the speed of the truck should be checked and the
function readjusted, if necessary.
Function 11 controls the speed at lift heights 24 inches. The
top speed of the truck must be 2.5 MPH.
Function 12 controls the speed at lift heights above 150
inches when travelling in a straight line. The top of the truck
must be 1.0 MPH.

The truck must be lifted and blocked with
the drive tire off the ground. Failure to do
so may result in the truck moving suddenly
causing serious injury or death!
