Appears like it is a telehandler (zoomboom) but not sure whether there are forks or a container attachment.

Everything is the same as a regular sit-down except the capacity is at its weakest when the boom is fully extended at its lowest height, and increases as the boom is elevated closer to the truck.

Frame tilt should be used BEFORE the boom is extended or elevated.

Boom should not be elevated unless outriggers are deployed, if it has outriggers

Boom angle greater than 40 degrees, the tranny locks up and parking brake comes on

If direction selector is activated within 3 seconds after startup, system must be restarted

Never drive with the boom elevated or extended

And level the frame before boom is elevated.

The rest, teach it as you would a sit-down. Basically, the same rules apply. They have to know how to read the capacity charts, which may be complex.

And from many thousands of miles away, that is the best I can do for you.

Check the operators manual for any further details, if one is available.
