How to Disconnect the MH-400 from the
Tow Vehicle
1. Park the tow vehicle and the MH-400 on dry, level
ground.
2. Set the parking brake on the tow vehicle, shut off the
engine, and remove the key.
3. Place blocks under the front and back of the wheels.
4. Relieve the pressure from the hydraulic system.
5. Disconnect the hydraulic hoses and the electrical
connection from the tow vehicle. Coil and store them
on the front of the MH-400.
6. On EH models disconnect and remove the control
pendant for dry storage.
7. Turn the front jack and rear jack leg 90 degrees
(clockwise) to the down position to support the
MH-400.
8. Lift the MH-400 with the jack until the weight is off
the tow vehicle’s draw bar. Pull out the hitch pin.
9. Ensure that there is no further connection between
the MH-400 and the tow vehicle.
Operating the Hydraulic Control Valves
on SH Models
There are three hydraulic control valves located on the
left fender of the MH-400 (Figure 13).
Note – Return all control valve handles to their center
position after use to avoid unintended starting.
Left Valve
The left valve controls the MH-400 conveyor belt
direction.
• To unload the MH-400, pull back on the control
lever. This moves material to the rear along the
conveyor belt.
• To load the MH-400, push forward on the control
lever. This moves material to the front along the
conveyor belt.
• To stop the conveyor belt, move the control lever to
the center position.
Center Valve
The center valve raises and lowers the MH-400.
• To raise the MH-400, pull back on the control lever
until the desired height is reached, then release it.
• To lower the MH-400, push forward on the control
until the desired height is reached, then release it.
CAUTION: Do not keep holding the
control lever in the raised or lowered
position once the lift cylinders have
reached their maximum travel position.
Right Valve
The right valve controls the option.
• To turn on the option, pull back on the control lever.
• To turn off the option, return the control lever to the
center position.
Note – Pushing the control lever forward does not have
any function. Options cannot be reversed.
WARNING: Do not leave the option
running while unattended.
I
MPORTANT: Do not pull the option lever into the on
position without an option mounted. This can damage
the floor motor and stop the MH-400.
