Operating Instructions

Connecting the MH-400 to the Tow
Vehicle
1. Connect the MH-400 hitch to the tow vehicle using
a 25 mm (1 in) diameter safety approved hitch pin
and safety clip (not supplied).
: Use a high-strength hitch pin that is
I
MPORTANT
approved for tow vehicle hitches.
2. Adjust the hitch height by turning the jack stand
handle to keep the MH-400 level.
3. Lower the hitch using the jack stand.
4. When the full weight of the MH-400 has been
transferred to the tow vehicle's draw bar from the
jack stand, pull the pin holding the jack stand in
place.
5. Turn the jack stand 90 degrees counter-clockwise
until the bottom of the jack stand points to the rear
of the MH-400. This is the traveling position.
: Raise the jacks into the
C
AUTION
traveling position before towing the
MH-400.
6. Connect the two hydraulic hoses from the MH-400
to the tow vehicle. Facing the front of the MH-400,
connect the right hose to the pressure side and the
left hose to the return side (Figure 12). The return
hose has an inline one-way check valve.
: The hydraulic lines, the power cable,
I
MPORTANT
and the pendant cables must not drag on the ground
during operation. Avoid locations where they could
become pinched or cut.
Note – If you are using the optional hydraulic power
pack, connect the hoses from the MH-400 to the power
pack.
7. Connect the power harness to the tow-vehicle.
Connect the pendant plug to the MH-400. On SH
models place the on/off pendant within reach of the
driver's seat. Ensure that the switch is off.

8. Check the hydraulic oil level in the tow vehicles tank
and add more to fill it, if necessary. (See the tow
vehicle's Owner's Manual).
9. Test the hydraulics before operating the MH-400 for
the first time.
: If you hear a noise from the
C
AUTION
tow vehicle hydraulics and the MH-400
controls do not operate, the hoses have
been connected incorrectly and must be
reversed.
Note - You may have to relieve the pressure in the hoses
of the MH-400 connecting to the tow vehicle, to ensure a
completed connection.
: When making sharp turns, the hydraulic
I
MPORTANT
hoses may contact the tow vehicle wheels. Avoid
making sharp turns, if necessary, use a bungee cord (a
rubber strap with hooks on both ends) to pull back the
hoses towards the center.
