Multihog CX75 Service manual

FIG. 1
Ensure the attachment stands are high enough to clear the load rails on the machine while
reversing into position (fig 1). Be careful not to reverse into the attachment while lining load
rails up with the attachment frame.

FIG. 2
When the attachment is on the rails ensure the pins supplied are put in the three positons
on either side of the load bed. Fig. 2
FIG. 3
Lock pin in place as shown above in Fig. 3 with R- key supplied.

FIG.4
When connecting the attachment hoses to the Auxiliary ports on the rear of the machine
note as stated below where each hose goes in Fig. 4 above.
1. (HPCO) The two hoses on the rear LHS highlighted in red are the oil feed and return
for the high pressure carry over.
2. (Motor) The three hoses highlighted in green on the rear RHS are for the oil supply,
return and case drain for the fan motor. These are all different sizes and coupling
types and will therefore only connect one way.
3. (Tip CYL.) The two bottom hoses on the rear RHS (Blue) are the oil supply and return
to the tipping cylinders.

FIG. 5
Plug rear attachment loom into socket on the front of the CX rear chassis. The loom (red)
and socket (blue) are shown above in Fig. 5. This supplies power to the solenoids on the
valve block on the rear attachment.

FIG. 6
When mounting the front trunk on the cab of the machine, use lifting points shown above in
Fig. 6 to lift the attachment safely. Use adequately specified shackles and crane to lift and
secure the trunk safely also.

FIG. 7
Attach the Trunk to the Cab using the bolts, spacers and washers supplied as above. Bolt the
trunk frame mounting points highlighted in red above in Fig. 7 to the tapped bushings on
the cab highlighted in blue.

FIG. 8
Connect the 6 hoses that run over the cab from the trunk Fig. 8 at the front of the
attachment. Each hose is tagged a specific colour (red, yellow & green) and should be
connected to the quick release couplers on the front as labelled above in the corresponding
colours.

FIG. 9

Before operating machine ensure that PTO flow has been adjusted correctly. Flow guidelines
outlined below.
1. Open machine RH rear chassis panel to gain access to the PTO Needle Valve shown
above in Fig. 9.The needle valve is behing the splitter box
2. Screw needle valve completely out.
3. Check Charts above in Fig. 9 for adjustment data to suit the specific pump fitted to
the machine.
4. The needle valve needs to be setup to achieve approx. 40L/min to operate the Cityvac
attachment properly.
5. If the machine has a 35cc pump screw the needle valve in 6 ¾ turns (shown above).
6. If the machine has an 18cc pump screw the needle valve in 5 ¾ turns (shown above).
7. The machine will reach sufficient suction at 1250 RPM.
Once setup properly excessive acceleration will have no impact on the flowrate being sent
to the cityvac attachment.Figures above are guideline only and a flowmeter must be used
for accurate flow control.
FIG. 10
To operate the Cityvac follow the procedure outlined below.
1. (HPCO) Engage lever B outlined in red and lock in place to operate the high pressure
carry over and send oil supply to the valve block on the rear attachment. This
operates supplies oil to the trunk cylinders.
2. (FAN) Turn on the fan by pressure the PTO button highlighted in blue above.
3. (Tip Cyl.) To operate the Tipping Cylinders, use lever A highlighted in green above.

FIG. 11
To operate the Trunk attachment, use the Joystick on the armrest shown above in Fig. 11
and follow the guidelines outlined below.
1. (Slew) To slew the trunk from left to right (Yellow Outline) push the joystick forwards
and backwards.
2. (Extend & Retract) To extend and retract the trunk (Red Outline) move the joystick
from left to right.
3. (Reach) To reach further forward or pull the trunk closer towards the operator
(Green Outline) twist the joystick knob.

LOOM INSTALLATION AND WIRING INSTRUCTIONS
FIG. 12
The loom supplied consists of an earth cable, socket for plugging in attachment, 2-pin power
supply plug, 6-pin joystick plug and a 15-pin Bucher controller plug. As shown above in Fig.
12, bolt the Earth cable down beside the front RH cab mount. The hole available is currently
used for mounting the horn behind the front auxiliary steel pipes.

FIG. 13
Track the cable with the socket for plugging in an attachment down the centre of the front
and rear chassis along the hydraulic hoses as shown above in Fig. 13. Fasten socket to front
chassis grill frame beside cab air duct using plastic nut as shown above.
FIG. 14
Track the other 3 plugs through the hose access vent on the RH underside of the cab as
shown above in Fig. 14.

Fig. 15
Note descriptions of the 3 plugs above in Fig. 15 for the next section of loom installation.
Fig. 16
Remove RH side panel on the inside of the cab for access. Track cables through the rear of
the side panel and neatly along the side of the panel towards back of the seat. Loop and
leave the 6-pin joystick plug in this position for now.

Fig. 18
Continue routing the 15-pin plug and 2-pin power supply plug along the inside of the cab
side panel towards the front. Loop and leave in this position for now.

Fig. 19
Cut slot approx. 140mm to the RHS of the rear mont hole on the side panel as shown above
in Fig. 19.
Fig. 20
Route wire through cab side panel and bolt panel back into place. Track wire to the back of
the seat.

Fig. 21
Bolt armrest attachment to the seat using M8 x 45mm stainless steel bolts and lock nuts.
Keep armrest height adjuster accessible.
Fig. 22
Track 6-pin plug loom through the back of the armrest and cable tie in place as shown
above in Fig. 22.

Fig. 23
Cable tie and sticky back the Joystick loom socket and 6-pin plug neatly under the armrest
attachment and out of sight as shown above in Fig. 23. Plug the 6-pin plug into the joystick
loom socket.
Fig. 24
Bolt the Bucher control unit on the inside of the side panel directly behind the cup
holder.Use bolts already there for holding the cup holder in place.

Fig. 25
Plug 15-pin plug into the bucher controller unit.
Fig. 26
Plug 2-pin plug for power supply into the spare power supply loom (red) at the front of the
panel. One is already in use for the cab power supply port (Blue) Fig. 26. Put external panel
back on machine and tighten bolts.
