remove the work platform. Do not engage a load before performing this

check. This test will require the use of an assistant.

1.)

Position Control Station selector Key switch to Cab (see page 3.0 in the

TF6-42 Operator Manual).

Start the machine from the cab. Raise the boom to approximately

zero degrees (horizontal) boom angle.

Locate an eight inch curb, and drive the machine’s left front wheel up

on the curb, leaving all other wheels off the curb.

Level the machine by operating the Sway function. No wheel should

leave the ground.

5.)

Back the left front wheel off the curb. Again, no wheel should leave the

ground.

Drive the left front wheel back up on the curb, and use the sway

function to level the machine. Set the park brake (shown on page 3.0

the right rear of the machine is “OFF”. Have the assistant disconnect

the proximity switch from the wire harness (keeping clear of the rear

wheels). The red LED should remain “OFF”.

Back the left front wheel off the curb. Again, no wheel should leave the
