Insert both of the Spray Arms into either side of the Arm Assembly Centre Post as far as they will go
-
Tighten the Connector Nuts until they feel secure when twisted
To prevent damage, do not lift or carry the Travelling Sprinkler by the Spray
Arms
Model of sprinkler may vary from illustration
Spray Arm Direction:
It is important that the Spray Arms are positioned correctly, otherwise the Travelling Sprinkler will not move properly, or it many not move at all
The Spray Arms must rotate clockwise to go forward
Spray Arms
Adjusting the Angle of the Spray Arms:
Adjusting the angle of the Spray Arms allow you to control the spray distance For maximum coverage, turn the tips upwards and out to approximately a 30º angle For minimum coverage, turn the tips slightly downward and clear of the Travelling Sprinkler body
Setting up the Hose Track
The Front Wheel of the Travelling Sprinkler is designed to be placed over top of the hose and then track the same path as the hose. On some surfaces the wheel may be prone to veering off the hose. Users should keep an eye on this when first operating the Travelling Sprinkler. If the surface is unsuitable, causing the Front Wheel to veer from the hose, it may be necessary to use an 18mm hose
The Travelling Sprinkler comes with both 12mm and 18mm Snap-on Hose Connectors
Up to 60 metres of hose can be used to lay out a path throughout the yard. To create 180º turns, a minimum radius of 4.5m is required
Place the Shut Off Ramp on the hose to stop the Travelling Sprinkler. There should be 1.5m of straight hose on either side of the Shut Off Ramp. Be sure to anchor the Shut Off Ramp into the ground with the attached spike
Please ensure the Stop Pin is pulled all of the way out on the underside of the Travelling Sprinkler. This pin will stop the Travelling Sprinkler from moving, but will not stop the watering
- For more information, refer page 6
Speed Control
Depending on the speed selected, the Travelling Sprinkler can travel from 6 to 11 metres per hour. LOW will apply more water, with HIGH preferred for lighter watering
To water a specific area and to keep the Travelling Sprinkler stationary, set the control to NEUTRAL
Sprinkler Operation
The small Front Wheel should straddle the hose track. The Stop Pin (on the underside of the Travelling Sprinkler near the Back Wheels) should be pulled out for watering
- Turn on the water and the Travelling Sprinkler should start spinning in a clockwise motion
- If it should stop, turn the water off and be sure the Stop Pin is pulled all of the way out
- Then slowly turn the water on again
The Stop Pin will stop at the Shut Off Ramp as travelling up the ramp will push the Stop Pin closed If you want to move the Travelling Sprinkler to new location
- Turn off the water to stop the pressure
- Pick up the Travelling Sprinkler via the base and move to the new location
- Layout a new path with the hose and place the Travelling Sprinkler on top of the hose
- Place the Shut Off Ramp in the new position
- Pull the Stop Pin back out before turning on the water again
Sprinkler Gears
Protect the water motor gears from damage by never operating the Travelling Sprinkler on driveways or footpaths
Do not push or pull the Travelling Sprinkler when it is operation
Do not let the Travelling Sprinkler get stuck in wet areas or low ground that
would keep the wheels from moving forwards, as this can damage the internal
gears
Do not manually stop the rotation of the Spray Arms. If you need to stop the
Spray Arms, turn off the water supply first
Sprinkler Maintenance
These points will help the Travelling Sprinkler work in the most effective way
- Clean the Inlet Filter Washer regularly by removing and rinsing it. A spanner may be required to tighten back together
- Drain the Travelling Sprinkler after use, especially in cold weather. Freezing will damage the sprinkler if water is left inside. This includes opening the Stop Pin
Sprinkler Flow Rate
Sprinkler flow rate for 12mm and 18mm Hoses
Chart calculated using 12mm hose of up to 30m length, with an average pressure of 275kPa. Dependent on sprinkler set up, flow rate ranges from 14Lpm to 20Lpm (average is 17Lpm).
Chart calculated using 18mm hose of up to 60m length, with an average pressure of 275kPa. Dependent on sprinkler set up, flow rate ranges from 15Lpm to 23Lpm (average is 18.5Lpm).
Values quoted may vary depending on hose length, spray coverage and water pressure
Coverage can be affected by several things including water pressure, hose diameter, hose length and hose weight.
The Travelling Sprinkler is made for established lawns. For delicate, newly seeded yards, another type of sprinkler should be used
