4.2.6 Test Drive Brakes
Instant UpRight specifications require this procedure
to be executed every 250 hours or quarterly,
whichever comes first.
The brake function is vital to safe operation of the
machine. The drive brakes should run smoothly and
without hysteresis and
abnormal noise. When a
single wheel brake that is released by electricity can
not be fully operated, they seem to be working
properly.
Note: This procedure is executed when the machine
on the platform controller is on the ramp and the
button is in the OFF position (the LED should be off)
and the platform extension table is fully indented.
1.Mark the test line on the ground as a reference.
2.Turn the key switch to the platform controller and
pull the red "emergency stop" button on the ground
controller and platform controller to the ON position.
3.Press the drive function selection button.
4.Press and hold the function enable button on the
joystick.
5.Select a point on the machine that is the point of
contact between the tire and the ground as a visual
reference point when the machine passes the test
leads.
6.Before the test line reaches the machine in full
speed drive. When the reference point on the
machine passes through the test leads, release the
function to enable the switch or joystick.

the machine reference points.
Note: On any slope where the machine can climb,
the brakes must be able to stabilize it.
