PREVENTION PLAN

DECREE N 92-158 of the 20th February 1992Modified by decree n 94-1159 of the 26th of December 1994

We remind you that the USER company (UC) must present its own prevention plan to the OUTSIDEcompany (OC).The user company (or customer) is responsible for prevention and safety on the building site.

Reminder: The manufacturer's assembly supervisors work under the user company's instructions (EE).However, the manufacturer's supervisors may impose certain safety measures (lifting means, individualprotective equipment (IPE)) on the user company.

SAFETY MEASURES

Building site :

Signposts must be placed at the entrance to the building site, forbidding access to all "outside"unauthorised persons and reminding authorised personnel that safety helmets are compulsory.

Compulsory equipment :

Safety helmet Gloves

Safety shoes (or boots)An approved safety harness for all works carried

out 3.5 m above the ground

DO NOT climb on the truss rods or pipes. For all operations on beams which have alreadybeen raised, you must use a ladder fixed to the frame or to the centre pipe, in order to avoidsliding during the operation. These works are often carried out on soft or muddy grounds. WARNING: The ladder may sink as these works are often carried out on soft or muddygrounds.

You must wear gloves when handling galvanised spare parts, as there are many sharpends.



5/41

Safety measures concerning cranes :

Cranes and maintenance vehicles must be driven by qualified personnel who possess aspecific driving licence.

Cranes must comply with the following conditions:

a) Lifting mechanisms must be equipped with a "descending" speed regulator.

b) As soon as the driver finishes, the breaks should engage automatically (the "dead man"device).

c) Command controls should return automatically to the "stop" position in the absence of thedriver's intervention. Hydraulic jacks must be equipped with an automatic valve to preventloads falling in the event of a hose breaking.

d) On equipment with a hydraulic mechanism (hydraulic crane) the pressure regulator,regulates the load. Nothing should be suspended from the hock when the crane is stopped.

e) It is forbidden to transport people on lifting equipment unless this equipment is designed forthat purpose.

f) It is forbidden to appoint drivers who are not familiar with safety measures and manoeuvresand whose ability has not been recognized by a medical examination, to drive cranes. Thisis also valid for workers directing these machines manoeuvres, by giving the driverinstructions.

g) Mechanical cranes must be placed on a resistant surface; the machine's limits must neverbe exceeded.

Cables, chains, natural and synthetic fibre cords must not be submitted to loads superior tothose laid down by the manufacturer, and approved by the Ministry of Employment. Theremustn't be any knots.

An authorized body must carry out trials and verifications regularly.

For hydraulic cranes, there is a French standard of manufacture NF E 52 088, approved byministerial order on the 22nd of April 1981 by the Secretary of State for Trade and Industry.



6/41

Necessary equipment to assemble an ST pivot :

Maintenance vehicle

A 4 wheel drive vehicle of sufficient capacity (minimum of 2.5 tons) to lift loads of spare parts (trussrods, pipes, beams, base beams/axle trees, etc); or a tractor with a trailer which can carry 12 m pipes,to distribute the equipment on the assembly site.

Cranes

A hydraulic crane. Considering the span's weight (see table below), it is necessary to have a crane withsufficient capacity to lift loads to a height, under the hock 5.5 to 6 m (minimum distance between thevehicle and the load: 2.5 m). We recommend a 4-wheel drive vehicle equipped with a telescopic arm(photo1).

Span weight (without water)ST127 (span length: 62.15m) 1768 kgST141 (span length: 62.15m) 1910 kgST168 (span length: 62.15m) 2076 kgSR193 (span length: 50.80m) 2018 kgSR245 (span length: 39.50m) 1992 kg

Straps

These must be approved for the loads to be lifted; it is preferable to use fibre straps, 80mm diameterminimum, equipped with steel rings at the ends, for better stability and in order to avoid damagingthe pipes when these are placed.

Spanners

Electric or pneumatic, depending on whether you have a generator or a compressor, with 19-22-24-27 and 30 diameter sockets (19 and 30 equipped with an extension, if possible).

Toolbox

One wire cutter, one electrician's knife, 1 wire stripper, and two screwdrivers: one 4x100 and one Ahammer, an adjustable spanner, a claw spanner and a ratchet wheel for the socket set.

Electrician's tool kit

One wire cutter, one electrician's knife, 1 wire stripper, and two screwdrivers: one 4x100 and one

Kit to lift the first beam

Two parts to be fixed on the tower pipe and on one of the tower legs before lifting the first beam.

ASSEMBLING THE PIVOTUnloading :

Check the material delivered corresponds to your order ( pipes, number of pipes, wheels,etc)

The beams must be assembled in line as much as possible to help adjustments when thepivot is activated (except for the first beam, see below).

Distribute the 12 and 6 m pipes, starting from the concrete slab - which corresponds to thecentre of the pivot; the pipes for the first span must form an angle -starting from the firsttower - to comply with diagram 1. To assemble the pivot take into account the piping plan(photo 2).

PIVOT ACTIVATION PROCEDURE

Procedures without water :

Reminder : Electric wiring and start-up must be carried out by qualified personnel.

Check all the gear motors are connected in the same way (by the colour) in all the

tower boxes. Also check the cutout switches work ( I = engaged). Adjust all the intermediate tower box connection rods -set stud in such a way that the cam engages

the micro-control switch (photo 98).

Photo 97

In the main switchboard, check all the circuit breakers work (F1/F2/F3/F4) and that there arecartridge fuses. Engage the differential switch (S1) then close the double door.

Engage the outside handle on the cutout fuse switch (picture 1).

Check the voltage between the phases (400v) with the fuse switch (picture 2) and the voltmeterswitch (switchboard B) or with a measuring device.

Set the WITH orWITHOUT WATER switch to WITHOUTWATER.

Set the FORWARDS/AUTO/REVERSE switch to FORWARDS.

Set the cyclic measuring device (picture 3) at 50%.

Start the pivot by putting the ON/OFF switch to ON.

The pivot should move anticlockwise. If it does not, stop the pivot immediately and reverse the 2

phases on terminals 7 and 8. The pivot should then work properly. Check all the intermediate tower box safety devices work by removing the ball joint. Also check the

last tower box by releasing the main switch of the last tower (during each operation the pivot shouldstop in SAFETY position).

Check the last tower safety device (option) works by manually operating the 2 END OF RUN switchesin both ways, in order to check both rotation directions.



38/41

Procedure to check the automatic reverse rotation system works properly :

1. Set the FORWARD/AUTO/REVERSE switch to AUTO. The END OF RUN switch should reverse thepivot direction. Carry out a rotation in both directions, by manually operating the 2 END OFRUN switches.

2. Set FORWARD/AUTO/REVERSE switch to FORWARD. When you manually operate the END OFRUN switch, the pivot should stop but not reverse run. If you release the END OF RUN switch,the pivot restarts and moves forwards.

3. Set FORWARD/AUTO/REVERSE switch to REVERSE. When you manually operate the END OFRUN switch, the pivot should stop but should not change direction. If you release the END OFRUN switch, the pivot restarts and continues run.

The pivot must not work unattended before completing a full rotation, in order to check the rotationand safety stops have been set up according to the instructions below.

Filling with water :

Check the sand box situated at the end of the pivot has been removed.

Shut the mini-valve on the centre element.

Fill with water, the pivot stopped, and allow the water to drain off through the sand box "exit" forabout 10 minutes, this will prevent the sprinklers from blocking up with impurities from the different

pipes. Stop the water and let the pivot empty completely.

Close the sand box.

Set the with WATER/WITHOUT WATER switch to WITH WATER; set the FORWARD/AUTO/REVERSE switchto the direction required; and set the ON/OFF switch to ON.

The pivot does not start and the safety pilot light is on.

Re-fill with water.

Adjust the water pressure at the entrance of the pivot according to the piping plan.

Using the screw located on the upper part, set the pressure switch so the machine starts at 1 barbelow working pressure.

Adjust the working speed control switch according to the chart and according to the quantity of waterrequired.

Check all the sprinklers work properly.

Check there are no leaks, tighten the flange bolts if necessary.

FAULT REPAIR CAUSE

Fuse failure in the QIcutout switch.

- Short-circuit on the power circuit betweenwires 7-8 and 9.- Using an ohmmeter, check the current, thereshould not be any.

- Short-circuit in the commutator.-Short-circuit in the tower box-connectingterminal.

1.Using an ohmmeter, check the transformer's1A.Am primary (380v) protection fuses.

- If fuses are faulty, replace them withidentical ones.- If fault continues, failure comes from ashort-circuit in the transformer.- This often results from over voltage.- Replace transformer.

2. Using an ohmmeter, check thetransformer's 4A Gg secondary (115v)protection fuses.

- Short-circuit in the 115V control:- in the commutator- in a valve- in the pressure switch or its cable.

- These fuses must be replaced withidentical fuses.Large diameter fuses do not increaseprotection

No control circuit.Voltage is correct butnothing works..

3.The fuses are correct but there is no circuitcontrol.

Using a voltmeter:- Check voltage on the transformer's primary(between wires 05 and 06). Voltage shouldbe 115v.- If the voltage in the primary is correct but

there is no voltage on the secondary, replacethe transformer; first check the secondaryprotection fuses are the right diameter (4AGg).

Replace HS transformer.
