COMPULSORY SAFETY SIGNS THAT THE MANUFACTURER
OF THE SYSTEM MUST DISPLAY IN THE WORK PLACE AND AROUND
THE GARDA OR LEDRA COMBINED GROUPS
CONDITIONS AND LIMITS OF USE – LIST OF DANGERS
In the Common Market countries, the installation must comply with directive 2006/42/CE and subsequent modications
while in the other countries it must comply with local safety regulations.
This rotary blades vacuum pump tted on the combined group has been designed to create a vacuum or pressure inside a tank
connected to it. The centrifugal pump on a combined group has the function of emptying the tank from the sewage content and
spreading it over a distance.
No solid materials of any type of size greater than the output hole of the swivel jet must enter the
centrifugal pump, in any case.
Any other use of the centrifugal pump, excluding the use specied above,
is strictly forbidden, not provided for by the manufacturer and therefore extremely dangerous.
Do not use the centrifugal pump to handle ammable and/or explosive liquids and materials or for
materials that release ammable gasses.
Do not use the centrifugal pump in potentially explosive atmospheres.
Never remove the guards tted on the centrifugal pump and always check their efciency every
time the machine is used.
Any work on the machine must be carried out while it is not running.
See the Instruction Manual for use and maintenance of the rotary blades vacuum pump.
Failure to comply with the instructions provided in this manual may result in the following dangers:
• Danger of being crushed by the weight of the combined group during handling and transport;
• Danger of becoming entangled in the shaft transmission parts if the necessary guards are removed;
• Acoustic danger due to the noise generated and to failure to use personal means of protection;
• Danger of severing for the operator during testing with the suction and delivery tubes detached from the pump;
• Danger of being knocked down by the outgoing sewage, due to the rotary motion of the swivel jet.
• Risk of the projection of solid and liquid material in the event of serious breakage of the centrifuge or of the vacuum pump.

When carrying out maintenance operations, inspections, checks or repairs it is advisable to wear
the individual protective devices listed in this manual.
All maintenance operations, inspections, checks and repairs must be carried out with the greatest care and
with the Rotary blades vacuum pump off and the P.T.O. disconnected.
The combined groups must be assembled and installed using the following procedure:
1) Install the GARDA or LEDRA Groups horizontally with the feet facing downwards.. The assembly position on the
vehicle should be easy to access and be protected. There must be sufcient space for the suction and discharge lines. A 5°
maximum longitudinal slope of the GARDA or LEDRA group with respect to the horizontal plane must not be exceeded.
2) Bolt the gearbox of the Group by means of the screws and nuts through the holes provided in the feet of the gearbox.
3) The centrifugal pump, connected to the gearbox, does not have support means;
4) Connect the centrifugal pump to the tank via a suction pipe of Ø 200 mm for GARDA or LEDRA 6500 and Ø 150 mm
for GARDA 3500, interrupted by a exible connection joint on the outside of the same tank;
5) Connect the centrifuge pump to the swivel jet via a metal pipe of 3" or 4" gas, on which must be tted a exible
connection joint and a gate valve that must be closed during lling of the tank-car;
6) The rotary blades vacuum pump only needs to be supported by a metal sheet of suitable thickness and a layer of rubber
between the metal sheet and the feet of the same rotary blades vacuum pump to prevent breakage due to vibrations of the
Group. Do not x the rotary blades vacuum pump with screws to the support plate.
7) Connect the suction/compression tube of the tank to the rotary blades vacuum pump as described in the "Instructions
manual for use and maintenance" of the individual pumps.
8) Connect the drive shaft of the tractor to the PTO of the GARDA or LEDRA group.

4 - START-UP, SETTING UP, TESTING, RUNNING
4.1 DIRECTION OF ROTATION
Before starting the GARDA or LEDRA combined group make sure that the P.T.O. shaft turns freely and that
the direction of rotation is the same as the one indicated by the arrow.
The STANDARD direction of rotation of the PTO shaft of the combined groups is LEFT.
Never allow the centrifugal pump to turn in the direction of rotation opposite to the one for which it was designed
(indicated by the arrow) as this could damage certain components as well as prevent operation of the rotary
blades vacuum pump.
4.2 RECOMMENDED OIL
Lubrication of the gears of the gearbox takes place through circulation of the oil contained in the box itself. The
gearbox is provided with an oil level plug, located on the front of the gear, which allows the level to be checked. To
ensure correct lubrication, the oil should always be visible in the oil level.
The lubricating oil must be poured into the gearbox through the oil ller cap on the top of the gearbox.
The type of oil to use is an additivated mineral oil ISO VG 460. Perform the initial oil change after approximately
100 hours of actual work and perform subsequent changes after approximately every 300 hours of actual work.
If the oil level is particularly low after an inspection, add some.
ATTENTION: it is possible to use ecological oil as long as it has the same ecological characteristics as the
recommended mineral oil. Do not use detergent or hydraulic oil for lubrication.

4.3 TESTING
To carry out testing of the Group verify the previous steps, possibly using a workbench. Ensure that the
shaft of the power take-off (PTO) turns freely and that the direction of rotation is the same as that indicated by
the arrow.
In case of verication of operation of the centrifuge without connection to the intake/discharge pipes, there
is a danger of shearing for the operators due to access to the inside of the centrifuge through the slurry inlet
and outlet openings. There is also danger under the same conditions of the intake of foreign objects inside the
machine. Check the functionality of the gear lever and the handle for the suction and compression of the pump.
4.4 RUNNING
A running period is not needed.
The recommended operating speed is 400/450 rpm for the GARDA or LEDRA 540 rpm group and 800 rpm for the
1000 rpm version.
5 - START, OPERATION, STOP
5.1 START
The Group does not have a start command. To start it simply start the PTO of the tractor after connecting it via the
cardan shaft. Ensure, before starting work, that the rotary blades vacuum pump and gearbox have sufcient oil for
internal lubrication. Any damaged or missing components must be replaced and installed correctly before using the
transmission.
Before starting the Group, make sure that the guards on all the moving parts are in place and efcient. Any
damaged or missing components must be replaced and installed correctly before using the transmission.
WARNING: the centrifuge is not self-priming.
Do not use the centrifuge dry, otherwise the mechanical seal could burn.
5.2 OPERATION GARDA 3500, GARDA 6500 AND LEDRA 6500
