return to the center position when released. Moving the lever slightly from the center
position results in a slow movement of the function which that valve controls. Moving the
lever further from the center position results in a faster movement. The function of each
control lever is identified on the end of the control knob.
The MHC REMOTE CONTROL UNIT allows you to operate the MHC from either side of the
vehicle so you can keep the load in sight at all times. A remote control switch switches
power to the REMOTE CONTROL UNIT. The REMOTE CONTROL UNIT is attached to the
MHC by a cable. The MHC responds to the REMOTE CONTROL UNIT levers the same as it
does to the levers at the control panel. The levers on the REMOTE CONTROL UNIT are
also spring-loaded and will return to the center position when released. The REMOTE
CONTROL UNIT has levers to operate hoist up/down, boom up/down, boom telescope
in/out, and swing clockwise/counterclockwise.
