Start Up Procedure/Operation, continued
8)
Turn on the water source to the MR32. The sprinkler
equipped with the MR32 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. Next engage the gearbox lever to the run position.
9)
Adjust the speed of cart retraction by moving the bypass
lever or speed control lever in the direction shown by the arrow.
Closing this valve will increase retraction speed and opening
the bypass valve will slow down the retraction speed
10)
Once the speed is set, the MR32 will automatically roll the
tube on the drum and stop at the end of the run utilizing the shut
off valve.
Troubleshooting
1) PROBLEM: NO WATER AT THE SPRINKLER
SOLUTION: 1. Make sure shut off valve is open.
2. Potential blockage—clean inlet hose /sprinkler nozzle.
2) PROBLEM: MACHINE WILL NOT ROLL UP
SOLUTION: 1. Make sure gearbox is in the engaged or run position.
2. Turbine bypass valve (speed control valve) is opened too far. Close valve to increase speed.
3. Turbine impeller not turning—open turbine housing and check for obstructions
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.
2. The machine’s mis-wrap safety shut down the retraction. Put the gearbox in neutral,
disengage the anti-reverse lever and pull the tube out all the way again. The level wind
timing may have been interrupted by too many loose wraps on the machine. This is
corrected by starting over and making sure the level wind guide is lined up correctly.
Call your Micro Rain servicing dealer with any questions regarding machine timing.
