General Safety
For the safety of others and yourself, please read and follow the precautions in this
operator’s manual. Pay particular attention to the following safety aspects of operating
machinery.
Do not ride on or allow passengers on the machine.
Always use a recognised hitch pin with a safety
clip to hook trailed implements on behind the
tractor.
Always ensure when using a quick hitch that the
locking tab has come out and is in the locked
position before moving.
When pulling trailed implements or loads, be sure
to use a tractor of greater or equal weight than
the combined weight of the load and trailer.

Carry a suitable fire extinguisher.
A fire can ignite under certain conditions, so please take the following precautions:
After running your machine for a short time, check for defective
bearings. A faulty bearing can become very hot, eventually
discolouring, requiring immediate replacement.
Do not allow combustible material to accumulate inside guards or
around rollers and other moving parts.
If your machine becomes blocked, stop immediately and remove
the obstruction.
Be careful when operating in hot or dry conditions or on extreme
fire risk days.
Never operate your machine without the safety
guards in place.
All chains should be properly
adjusted and replaced when
necessary.

Multiplus Operation & Parts Manual
Release all hydraulic pressure from
implements before commencing service
work. Never look for suspected oil leaks
with your hands or body - use a piece of
cardboard instead.
Any fluid that penetrates the skin will
have to be removed immediately by a
medical expert. Seek specialist advice
on this type of injury.
Never attempt to unblock equipment while it is
still operating.
Always disengage power take-off, hydraulics and
shut down engine before removing materials,
checking or servicing.
Failure to follow these precautions is likely to
result in serious injury.
Wear proper protective clothing. Loose attire can easily
be snagged by rotating machinery resulting in serious
injury or death.

Pre-Service Guidelines & Settings
Prior to delivering your machine, your dealer should have completed a pre-delivery
check.
It is beneficial to check the following points before using the machine for the first time.
CHECK FLOOR CHAIN TENSION. A simple check is to stand in the bin and exert a
strong pull at the centre of the floor. There should be approximately 75mm (3”) of
vertical movement in this area.
CHECK ELEVATOR CHAIN TENSION. With elevator fully raised, exert a pull at the
mid-point of the outside elevator face. If necessary, adjust for approximately 35mm (1-
1/2”) of movement from rest outwards.
CHECK ALL WHEEL NUTS ARE SUFFICIENTLY TIGHT.
CHECK ALL TYRE PRESSURES ARE CORRECT.
CHECK ALL AXLE MOUNTING BOLTS AND NUTS ARE SUFFICIENTLY
TIGHT.
THERE ARE SEVERAL GREASE POINTS on all Giltrap feeders. Check the
yellow label on the side of your machine to see how many grease points there
are. You should fully grease everything before running it for the first time. See
page 11-13 for greasing and lubrication details.

Operation
Loading the Feeder
Load the feeder from the rear to the front. When difficult material has to be handled, e.g.
long, wet silage, load the material in sections.
Feeding Out
Best feeding out conditions occur when the feeder is freshly loaded. If left loaded
overnight, the material can settle into a hard mass that becomes difficult to feed out.
The practice of leaving a load in the machine for hours before feeding out will also
accelerate the deterioration of the machine because of the acidic nature of the material.
Standard Control
Standard machines will require three hydraulic remotes - one for each of the main
functions. The main floor conveyor, the cross conveyor / elevator, and the elevator
position.
When pressure is supplied to the standard valve block (HCV1918A-1), the elevator will
run continuously and the cross conveyor will move as required to keep the feed against
the elevator. The relief on the valve block can be adjusted via the knob on the left of the
machine. Winding the adjuster clockwise increases relief pressure which will increase
the feed rate.
The main floor is manual and requires the operator to control the movement of feed
from the bin onto the cross conveyor. If required, the main floor can be reversed.
The elevator position can be adjusted to feed into troughs or over/under fences.
The standard side gate on the left of the machine can be unlatched and can be used to
feed out.
Diverter Valve Control Option
Machines fitted with a diverter valve will require two hydraulic remotes. One will supply
the diverter valve and the other will control the standard valve block. The diverter valve
can be switched via the in-cab control to supply the elevator ram circuit or the main floor
conveyor motor. The other remote will control the cross conveyor and elevator
(HCV1918A-1) as per standard spec above.
The diverter valve is controlled by a coil which is powered on or off to give the two
selectable positions. When the coil is switched off, the valve is in position 1 which
diverts flow to the main floor motor. When the control is switched on the coil moves the
valve into position 2, diverting flow to the elevator ram circuit.
It is recommended that the diverter valve switch be connected to an ignition switched
power supply so that if the controller is left set to the position where the coil is switched
on and the tractor is turned off, the battery is not drained.

Multiplus Operation & Parts Manual
Joystick Control Option
Machines fitted with joystick control will require one hydraulic remote. This supplys a
valve block which is controlled by the in-cab joystick and switch. The joystick controls
the cross conveyor feed (Joystick left and right) and the main floor feed (Joystick up and
down). The feed rate can still be adjusted as standard, using the adjustment knob on
the left side of the machine. The momentary switch controls the elevator position.
The joystick control valve block is controlled by 6 coils. The coil plugs on the valve
block, numbered 1-6, are connected as show below:

Scales Display & Power Supply
The remote display is designed to be mounted in the tractor cab and be easily
accessible to the driver. It contains a radio frequency (RF) communication device to
communicate with the scale system.
It will require shielding from the weather elements of sun and rain etc.
The remote display requires 12-24 volts DC to operate. It will typically only draw 0.2A.
The power supply must originate from the tractor battery as part of the installation loom
(supplied with the machine).
The scales system is powered from the tractor while operating. When disconnected
from the tractor, it draws power from its own sealed lead acid battery.
The tractor requires an installation loom (supplied) which provides a switched and fused
positive and negative supply from the tractor battery to the rear 7-pin socket. The tractor
battery is the best power supply point as it provides the most stable and “quiet” power
source. Do not use any other power source.
Tractor Plug
There are three CPC connectors on the Control module.
If a connector is not used, place the terminal cap over it.

Multiplus Operation & Parts Manual
Hydraulic Requirements
For optimal machine performance the tractor used should be checked to provide an oil
flow rate of between 30 and 45 litres per minute at full working pressure –Usually
between 2500psi (170 Bar) and 2800psi (190 Bar). If these conditions are not satisfied,
the feeder will perform poorly or not at all.
Technical Notes:
Machines that develop or operate with a jerking or shuddering action can be
rectified by fitting a non-standard inline valve (SCCB 154Z P8) with relevant
fittings between the port marked “ELEV PRES: and the elevator motor. This
preloads the hydraulic circuit and smooths the operation.
Quick Valve Orifice Diagnosis
If orifice (5) is blocked then the cross conveyor
will not drive load onto elevator when loaded.
If orifice (6) is blocked then the floor will not slow
down when the DPBB (3) is adjusted out and
floor will likely overload and stall the elevator.
