MHC WILL NOT OPERATE WITH REMOTE CONTROLS.
Step 1. If using remote control, check electrical connections at the remote
control and at the MHC hook up.
Step 2. Check that outrigger jacks are firmly deployed. If not, lower
outrigger jacks until front suspension is unloaded and tires do not bulge.
Operator will have limited visibility of load when using the manual
controls. Use a ground guide to relay signals to the operator. Boom
and load moving out of control could cause serious injury or death.
Step 3. When operating the remote control, check that manual control levers
move when the remote control unit is operated.
If levers do not move, use manual controls to operate MHC.
