WARNING
OPERATING CONDITIONS
1. The machine must be towed by a tractor whose weight is greater than or at least equal to the weight of the
machine plus the weight of the water inside the hose. For more details on this refer to the section on
“TRANSPORTING AND HANDLING THE SPRINKLER”.
2. The Highway Code current in the country of use must be followed whenever the machine is transported
on road.
Note that RM sprinkler machines are not certified for on-road operation.
The machine must be fitted with a rear light assembly connected to the tractor’s electric system and attached on
the back of the machine, i.e. on the rain gun skid carriage.
RM Spa recommends all users of its equipment to obtain information on the current
Highway Code in force in the country where the machine will be used. RM Spa declines
all liability for injury to people or damage to property caused by road accidents.
Tractor speed when towing RM equipment must not exceed 15 Kph. Speed higher than
this can cause the sprinkler’s tyres to explode with serious consequences for operator
safety or that of other users of the road.
Do not operate with the machine inclined at an angle on gradients higher than 3%. This is
extremely dangerous.
3. Water supply to the machine must be done by means of a pressurised water line ( supplied by the mains
water supply, a pump connected to a tractor, an electric pump, etc .).
It is essential that the operating pressure at machine intake is between 3 and 12 bar (pos. 1, photo H) at the
volume indicated in the rain gun’s user Chart. Pressure must be constant and at full operating volume, must not
vary by more than 1 bar.
If the supply water line is subject to the so-called “hammer effect” ( this is often in the case of water company
supply lines ), a pressure relief valve set at 11-12 bar should be installed at machine intake.
Failure to take this precaution can cause serious damage to the machine and also be a source of danger
to the operator.
It is recommended to check to make sure that the fittings used on the water feed line are good quality. It is
absolutely not advised to change the fittings factory installed on the hose with others available on the market.
4. RM sprinkler systems have been designed to have a centre of gravity as low as possible. However, it is
good standard practice to pay special attention when operating or simply towing on rough roads, gradients
or bad surfaces in general.
It is important to remember that, once the machine has been used for the first time, the water in the hose will not
only increase the weight of the machine but also shift its centre of gravity upwards. This means that there is an
increased risk of the machine tipping up or over.
WARNING
Position the machine at its work area. The sprinkler will appear as illustrated in Photo A.
To make it operational, the following steps will be required:
A. Lower the drawbar support foot and detach the tractor. Check to make sure that the support leg (pos. 9,
photo A) is firmly anchored on the ground.
