Safety
Recognise Safety Information.
Please pay attention to these signs for your own safety
This is a safety alert symbol. When you see this symbol on your machine or in this
manual be alert to the potential for personal injury.
Follow the recommended guidelines for safe operating practice:
Understand signal words: - On machine safety signs, signal words give the level of the hazard.
Danger
Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
Warning
Indicates a potentially more hazardous situation which, if not avoided, could
result in death or serious injury.
Caution
Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury. You will find these signs located near specific hazards
on your machinery.

Safety Checklist
“ DO’S “
•Always disconnect all power sources before carrying out any adjustment or
maintenance.
•Always check around the machine making sure everything is in order; this will only take
a minute.
•Study this manual. Provide training to new users. Like all farm machinery, any machine is
potentially dangerous when under the control of untrained personnel.
•Always ensure guards and other safety devices are kept in good working order. Replace
if necessary.
•Keep clear of all moving parts.
•Always keep all hydraulic hoses and electric cables clear from PTO shaft.
•Always apply the handbrake before unhitching and park the machine in a level area.
•Always take extra precautions when using the machine on hilly or sloping ground.
•Before unfolding the machine, ensure that no one is standing in the operating area.
•Before traveling on roadways set machine in transport position.
“ DON’T’S “
XNever permit untrained personnel to operate the machine without reading this manual and
or receiving training.
XNever operate the machine without having all guards in place; they are there for your safety
and protection against serious injury and death.
XNever remove guards while there is still power going into the machine, all power must be
off!
XNever operate the machine if you think there could be large stones or foreign objects inside,
they could cause serious damage to your machine.
XNever leave the machine running when unattended.
XIf the machine should become blocked with a stone or foreign object, do not attempt to free
the object while the tractor is running.

Description of Safety Warnings and Instructions
The following is a list of safety signs and warning labels on the Hi-Spec Dribble Bar. Look carefully
and make sure you know where on the machine they are positioned and what they mean.

Getting Started
4.1
Machine Requirements
•1x double acting service set to 70L/min (for the folding and unfolding service as well as
running the macerator )
•1x 12volt power supply(cab mounted diverter switch)

Fitting Dribble Bar to machine
The dribble bar is mounted to the tanker at three points. The two lower points use a hook and pin
type coupling, this is to allow the machine to be lifted on to the tanker easily. The top point is
coupled by a pin this secures the trailing shoe to the taker.

➢Preform installation on flat level ground.
➢Lift dribble bar with pallet forks at designated points.
➢Lift dribble bar into position on the tanker.
➢Line up the lower hooks with the mounts on the tanker
➢Lower the dribble bar making sure that the hooks are seated on the pins.
➢Move the dribble bar until the top hole lines up with the corresponding hole on the tanker
and install the pin.

4.3
Fitting hydraulics
The hydraulic services for the dribble bar are located at the back of the tanker. This is to allow the
removal of the dribble bar unit from the back of the tanker (as shown in picture below). These
services control the folding/unfolding of the boom, the macerator and gate and the raising /
lowering of the trailing shoe.
The macerator and gate service are shared with the folding and unfolding service, this is selected by
using the electronic control box.
•Ensure hydraulic quick –connect fittings are clean and dirt free
•Ensure all hydraulic fitting are properly connected to the tractor
•Hydraulic services are colour coded by function

4.4
Fitting electrics
The electrical services are located at the back of the tanker in the same place as the
hydraulics. These are to supply power to the lights and to the electrical solenoid valve for
controlling the hydraulics.
•The lights are supplied with power by a 7-pin plug, which is connected at the back of the cab
•The electrical functions are supplied with power via 3-pin plug, connected inside the cab.

4.5
Using the Diverter Valve
To reduce the number of double acting services needed to operate the machine, a diverter
valve is used. This valve is electronically controlled from a switch box, which is mounted
inside the cab of the tractor. This valve allows the operator to select between using the
macerator/ gate and the fold/ unfold function, with the same hydraulic spool valve.
In the first position shown below, the switch is set to control the folding / unfolding of the
machine. Using the spool valve now will fold or unfold the machine.
In the second position shown, the switch is set to control the macerator and gate valve. The
gate valve is opened automatically by the backpressure created by the motor on the
macerator. The light on the switch will turn on when the macerator is selected.

Operating Instructions
The following combinations will give quickest cycle time.
Dribble Bar Operation
1. Unfold dribble bar using the double acting service.
2. Set vacuum pump to spread
3. Engage PTO and operate at 540 RPM max.
4. Select correct forward speed for spreading rate.
5. Ensure that the diverter switch in the cab is set operate the macerator
6. Operate the double acting service and start the macerator. This should also open the gate to
the macerator. (The hydraulic line from the splash plate can be moved to the gate for
manual operation.)
7. When finished spreading reverse step 1-7.
Allow 5 seconds between turning off the macerator and switching over to folding the boom. As
the macerator takes time to slow down. If the oil cannot escape back to tank, the back pressure
will open the gate slightly causing problems when filling.
Set lever to float when stopping the macerator.
To reduce wear on the macerator blades, the direction of drive should be reversed every second
cycle. This is done by operating the double acting spool in the opposite direction.
N.B. Never run the PTO shaft when it is not straight.
Never run the macerator dry for more than 30 seconds.

16
Splash plate operation
1. Set vacuum pump to spread.
2. Engage PTO and operate at 540 RPM max.
3. Select the correct forward speed for spreading rate.
4. Open the splash plate gate by using the single acting service.
5. When finished spreading reverse step 1-4.
