Next Generation Excavator Operator Training: E-fence Swing 

Per your manuals... Doesn’t the work with heavy material. Only works with hydraulic temps being just right (not too cool or too hot). Doesn’t work with rough or dangerous operation. Doesn’t work if the machine is not stable due to uneven ground. Doesn’t work if the engine speed or hydraulic power setting is too low. Doesn’t work if the machine is operating on terrain with a steep slope angle. Doesn’t work if a work tool or front linkage was changed without the required calibration.

Nice
