PROBLEM The machine moves or slides on the ground when reeling in the hose
REMEDY Attach the rear support legs better.
If this does not work, act immediately with the following procedure:
Put the gear lever in 4th (refer to the section “REGULATING REELING IN SPEED”; disengage
the stop dog (pos. 2, photo H); open the by-pass valve to slow down or stop the turbine. Do not
touch lever (pos. 7, photo H). At this point, the reel will turn in the direction opposite to its reeling
in direction. Allow the tension on the hose to slacken off.
When the machine stops, reposition the rear brackets but select a spot where the ground is
more solid and compact.
If necessary, turn the swivel plate to move the reel’s axis in line with the hose.
When the hose is unreeled for more than 3 hours under particularly damp conditions (rain or
very wet ground), when re-reeling it, the hose should be raised above the ground using 10-12
cm thick wooden spacers.
This is very important otherwise there is a real risk of the hose breaking and, consequently,
irreparable damage to the reel . RM Spa declines any liability for damage caused by failure to
observe this standard operating procedure.
PROBLEM During re-reeling, the hose is badly reeled or is outside the reel.
REMEDY Follow these instructions for perfect re-reeling:
Unreel the entire hose (the very first time and thereafter once every four unreeling and re-
reeling cycles). If the hose is partially unreeled, check at the beginning of the work cycle to make
sure that the coils still on the reel are perfectly placed. It is essential that (for at least 50 m from
the machine) that the hose is perpendicular to the axis of the reel. Thus when the hose is reeled
out by the tractor, check to make sure this is the case (if necessary, turn the swivel plate to
achieve this alignment). It should also be noted that, in the first 20-30 unreeling cycles, hose re-
reeling cannot be perfect until the hose has fully adapted to the reel.
If the problem is not solved after carrying out the steps outlined above, remove the plastic
casing on the side opposite the turbine and with the machine stopped.
Count the number of teeth in pinion installed on the wheel shaft and the number of teeth on the
pinion on the hose slide shaft. Give these numbers (plus the hose diameter and length) to the
RM Technical Assistance Service.
PROBLEM The rain gun carriage does not return correctly during rewinding.
REMEDY
If the wheels of the rain gun carriage tend to lift off the ground during re-reeling (check this 15-
20 minutes into the re-reeling cycle), widen the wheel track or add ballast on the sides of the
carriage.
It is always best to have the rain gun carriage working with the right and left wheels at equal
distances with the hose between them.
When the rain gun is used on one side, make a slight furrow in the ground in which the hose will
be held during rewinding.
If the machine is used on hilly land or land that is not completely flat, it is best to place the rain
gun carriage on the lower side so that the machine will take in the hose reeling it from above.
PROBLEM The hose is oval shaped when the machine is supplied from a well or from the water
mains.
REMEDY This is caused by two negative effects working together:
° the low pressure normally found in this kind of supply source.
° pressure drops in the supply to levels insufficiently high to operate the system.
Since we can do nothing to remedy the problem of low pressure main supply, due to the inconstant
pressure, the machine should be used at the lowest re-reeling system possible. It is also good
practice to leave the stop dog disengaged (pos 2, photo D) to allow the reel to recover partially
if there is a drop in supply pressure.
