If necessary, to level the bracket,use custom-made gussets to attach the
bracket to the counterweight. To fabricate the gussets, use 12.7 mm (1/2 in)

directions (forward and back, left and right). Adjust if necessary.
3. When everything is correct, weld the bracket securely.
6.12 Control box mount
If you have purchased a machine-specific base kit, then a control box mount
designed for your machine is supplied. Otherwise, use the generic mount supplied in
the generic machine base kit.
Depending on the type of mounting method, some fitting and welding work may be
required to install the control box mount. If no fitting or welding work is required,
you can install the control box when you install the other cab components. For more
information, see 7.3 Control box.
The best location for the control box is one of the front corners of the cab.
However, this will vary with the type of machine and the operator’s requirements.
Make sure that:
l the control box:
is within the operator’s reach, and the USB flash drive is easy to remove
and replace
is easy to see but does not block the operator’s view
will not interfere with the operator’s activities
will not obstruct the operator when getting in or out of the cab
is easy to connect and disconnect
l the cab cable reaches the control box
In this case the mount is clamped to the machine's console and no fitting or welding
work is required.
