Introduction
Thank you for purchasing a Micro Rain MR25 traveling sprinkler system. Please read this
manual carefully before operation in order to become familiar with all components and their
function. Safety is the main priority and failure to follow these instructions may cause serious
injury. Micro Rain is not responsible for machine failure or personal injury if these procedures
and operation instructions are not followed.
Do not operate your Micro Rain traveler without a serious overview of this manual
 Keep children and unauthorized people away from traveler
 Never allow children access to use the traveler
Use caution when disconnecting couplings
When the traveler shut-off valve activates, the supply hose remains pressurized at the end of the run.
First, relieve the pressure with the relief valve, then disconnect the supply hose.
Use caution with the sprinkler heads
Pressurized water from the sprinkler head could cause serious damage to people or objects.
Use caution during transport
Travelers are not made for public transit. Do not exceed 7mph on flat roads, or 2 mph on steep inclines.
Never service the traveler when it is in operation
Before servicing, stop the traveler and disconnect the supply line. All safety guards and shields must be in
place while operating the traveler.
Beware of power lines
Irrigation water should never contact power lines or any other power source. Never let any part of the
traveler or any irrigation pipe get in contact with power source.

Conditions For Machine Operation
The MR25 is designed for clean water suitable for irrigation. The machine is not designed for
water that includes large pieces of debris or slurry/wastewater conditions.
Start Up Procedure/Operation
1) Push the machine to the desired location. Position the ma-
chine with the sprinkler cart facing the direction to be irrigated.
Insure that the machine is sitting level in order for the tube to
wrap properly.
2) Loosen the black turbine lock knob as shown at the bottom
of the image to the left by turning counter-clockwise. Now the
turbine drive assembly and bracket will slide towards the sprin-
kler cart (as shown by white arrow) to disengage the turbine
drive gears. Re-tighten the knob to hold the turbine drive gear
away from the drum gear. Drum will now spin freely allowing
sprinkler cart to be pulled out.
3) Sprinkler cart may now be pulled out by hand.
IMPORTANT: Pull the sprinkler cart out in a straight line
from the machine to allow the tube to wrap back onto the drum
straight. Never make sharp turns with the polyethylene hose
and always leave one or two wraps on the drum to keep from
pulling the tube off of the drum.
4) Proceed back to the drum and tighten the few loose coils that
are left on the drum by hand. This will ensure that the coils
start wrapping in the correct manner when the drum starts turn-
ing.
Keep remaining wraps tight!!

**IMPORTANT: ALWAYS PULL CART OUT STRAIGHT AND TIGHTEN LOOSE WRAPS BEFORE START UP!
Keep Wraps Tight!Always Pull Tube Out Straight!
Start Up Procedure/Operation, continued
5) Re-engage the turbine assembly by loosening the black knob
again and sliding the turbine bracket back into place as shown by
white arrow, so that the drive gears mesh. Tighten the black lock
knob again to hold the turbine in place.
IMPORTANT: Before proceeding, try turning the drum by hand to
make sure it is locked in gear. It should be locked and will not turn.
7) Attach supply hose provided to the inlet of the machine and lock
into place as shown
IMPORTANT: MAKE SURE SUPPLY HOSE IS CLEAN AND FREE OF
FOREIGN OBJECTS THAT WOULD PLUG THE TURBINE SYSTEM
OR SHUT OFF VALVE!
6) Open shut off valve by pulling the valve handle and latching
into the open position by swinging the valve latch down and into
position to hold valve open as shown.
IMPORTANT: PULL VALVE, DO NOT TURN!
NOTE: DO NOT PULL VALVE OPEN UNDER PRESSURE. OPENING
UNDER PRESSURE WILL DAMAGE VALVE!
VALVE SHOWN IN OPEN, LATCHED POSITION

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.
