1 Product descriPtion
The foam marker transforms a mixture of foaming agents, added to clean water, into a foam that
can be seen on the ground.
The foam, which is inert, visually marks out previously treated areas of crop, thus avoiding double
treatments, product wastage and potential damage to the crop.
1.1 Intended use
Device designed for installation to crop-spraying, spraying agricultural machinery
and forestry machinery.
This equipment has been designed and manufactured in compliance with the fol-
lowing directives and standards:
•2004/108/CE and subs. mod. (Electromagnetic Compatibility);
•97/23/CE and subs. mod. (Pressure equipment);
•98/37/CE and subs. mod. (Machinery);
EN ISO 14982 (Agricultural and forestry machinery - Electromagnetic Compatibility -
Test methods and acceptance criteria).
2 Precautions
•Foaming agents in general are potentially toxic!
•Only use the foam marker outdoor or in well ventilated environments wearing
the required individual protection gears, overall, gloves and mask.
•Never expose the equipment to water jets.
•Never use solvents or petrol to clean the external parts of the container.
•Do not use direct jets of water for cleaning the device.
•Comply with the specic power supply voltage (12 Vdc).
•In case of electric arc welding, make sure that the power supply to the device
is disconnected; if necessary, disconnect the power supply cables.
•Use only original ARAG spare parts or accessories.

5.1 Precautions
When installing the foam marker it is necessary to observe a few essential rules:
•When xed, the compressor unit should be sheltered from sprayed products or stones which
can be thrown by tractor wheels.
•On seeders, install the electric-compressor unit sheltered from areas that are too dusty.
•Install the foam marker at bar ends using the supplied supports at a distance from the last
spraying nozzle equal to half the distance of one nozzle to the other (Fig. 3).
•The foam must fall in an area sheltered from the nozzle and the point where it falls must mark
the area treated by the boom.
•Fix the pipes of the pneumo-hydraulic system to the framework with clamps, in a position pro-
tected from possible impact with the ground or with the boom framework.
•At the joints of the booms the pipes must be of
such a length as to allow the booms to open and
close without damaging the pipes.
•Place the tank upright with the cap easily acces-
sible for lling and adjusting the ow rate.
•Apply the tank so as to make it possible to be
removed for periodical washing.
•The compressor cover should be easily removed
for maintenance operations.

5.4 Installing tank and compressor unit
Tank and compressor unit can be installed onto the machine in two different ways:
5.5 Installing the foam markers
Install the foam markers at bar ends as specied below:
Horizontal foam markers
Fi g. 6
Fig. 7a
1Fix the compressor unit (C) to the tank
holder basket (B) and then install the
assembly onto the machine.
2Install compressor unit (C) and tank
holder basket (B) separately.
Should this be the case, the compressor
and the basket can be directly installed
on the machine.
Always use the supplied screws.
• Drill two Ø 6 mm holes at a distance of 100
mm on bar (A).
•Fix the bracket (B) to the bar with the sup-
plied M6 screws.
•Repeat the operation with the other boom.

Vertical foam markers
5.6 Mounting the pneumo-hydraulic circuit
- Connect the white tube (air) and the blue tube (uid) to the foam marker which is the farthest from
the compressor unit. Ensure that each tube is connected to a connector of the same color.
- Lay the piping along the framework of the boom as far as the electric compressor unit, leaving
plenty of it by the joints.
- Connect the tubes to the compressor unit ensuring that each tube is connected to a connector
of the same color.
- Connect the foam marker which is the nearest to the compressor unit and repeat the above
procedure.
- Connect the dark blue pipes (liquid) and the white ones (air) to the ttings of the same colour on
the tank cap.
- Cap the tank.
• Drill two Ø 6 mm holes at a distance of 100 mm
on bar (A).
•Fix the bracket (B) to the bar with the supplied
M6 screws.
•Fit the foam maker (D) onto the knurled section
of the bar (B) and x with the supplied screw
(E).
•Repeat the operation with the other boom.

5.7 Installing the control box
If the contact 15/54 (auxiliary) of the starter key can withstand a continuous load of
10A, make the connections of Fig. 10 section A. Otherwise, insert a relay as shown in
Fig. 10 section B.
Minimum cable cross-section: 2,5 mm².
CAUTION: so as not to run the risk of short-circuiting, do not connect the supply
cable connector until installation has been completed.
•Fix the electric cables, making sure that the connections are mounted in a protected
position.
Fi g. 10
•Connect the control box to the compressor unit using the supplied cable.
5.8 Accessory connections: positioning the foam marker control kit
To use the foam marker with a BRAVO computer install the foam marker kit as de-
scribed in the instructions supplied with the very kit (please refer to ARAG General
Catalogue for part numbers).
5.9 Final testing
1) Insert some litres of water into the tank.
2) Screw the cap onto the tank fully.
3) Move the selector (A, Fig. 12) to the right and start the compressor unit.
4) Ensure that uid comes out from the right foam marker after some seconds.
5) Check the correct seal of the hydraulic couplings.
6) Shift the selector to the left (A, Fig. 12) and start the compressor unit.
7) Ensure that foam is coming out from the left maker.
8) Check that no hydraulic connections are leaking.
9) Interrupt delivery by setting the switch to its central position (OFF).
10) Depressurize the tank as indicated in par. 6.1 - Discharging remaining pressure.
11) Empty the water from the tank.
12) Clean the circuit as described in chap. 7 - Maintenance / diagnostics / repairs.
•Install the control box into the driver’s cabin: position
the fastening slide with the screws (Fig. 9) where
the driver can easily see and reach the box provided
that it is far from any moving parts; secure the con-
trol box to the slide by inserting and pushing it down
until it locks in place.
•Fix the wirings so that they do not come into contact
with moving parts.
•Connect the supply cable to the starter key 15/54.

6.2 Control devices
6.3 Preliminary checks
After a long period of disuse and before every new use, check the tightness of the
ttings.
6.4 Preparing foaming solution
•Pour an amount of concentrated foaming liquid into the tank according to the instructions
given on the package of the product (see par. 6.6).
•Add clean water to ll the tank, using a pipe inserted down to the bottom of the tank so as
to mix the product well and prevent foam from forming.
•Screw on the cap and tighten it carefully.
•For use during the winter, add automotive antifreeze in the amount specied on the anti-
freeze package.
•Cut off the supply to the foam marker.
•Pull the red pin of the relief valve onto the tank
plug and then discharge any residue pressure as
shown in the gure.
