Start Up Procedure/Operation, continued
8) Turn on the water source to the MR25. The sprinkler
equipped with the MR25 can be set to water a full circle pattern
or any part of a circle. It is generally recommended to water a
half circle pattern behind the cart, away from the direction of
travel. The MR25 is equipped with a pressure regulator at the
inlet to maintain system pressure at no more than 60 psi.
9) Adjust the speed of cart retraction by moving the bypass
lever or speed control lever in the directions shown by the ar-
row. Closing this valve will increase retraction speed and open-
ing the bypass valve will slow down the retraction speed
10) Once the speed is set, the MR25 will automatically roll the
tube on the drum and stop at the end of the run utilizing the shut
off valve.
IMPORTANT: Your MR25 traveler operates between 3 and 11 gallons
per minute. This is regulated by changing the sprinkler nozzle to match your
water source’s capability. The smallest nozzle is installed in the sprinkler
from the factory. If you have a good water source with adequate pressure, it
is possible to increase to a larger nozzle size if needed. Consult your appli-
cation chart and servicing dealer for more information.
Troubleshooting
1) PROBLEM: NO WATER AT THE SPRINKLER
SOLUTION: 1. Make sure shut off valve is open.
2. Potential blockage—clean inlet screen/sprinkler nozzle.
2) PROBLEM: MACHINE WILL NOT ROLL UP
SOLUTION: 1. Make sure turbine is in the engaged or run position as shown in start up steps.
2. Turbine bypass valve (speed control valve) is opened too far. Close valve to increase speed.
3. Not enough pressure to initiate turbine drive.
4. Debris in inlet filter screen not allowing flow into the machine.
3) PROBLEM: MACHINE STOPPED DURING RETRACTION
SOLUTION: 1. Water flow stopped or was lowered during retraction, causing the turbine to stall. Simply turn
the bypass valve closed to start retraction once again and adjust speed as needed.
