Set Operating Height: Use the Tool Plunger (1) to adjust the tool's position on the robot. The plunger must be set in the 9th hole from the top. This means you will see 8 holes visible above the plunger.
Verify Spray Alignment: To ensure the height is correct, run a test spray. The spray from the fan nozzle should hit the exact center line of the disc. You can initiate a test spray using the robot's tablet interface or the yellow and blue buttons on the robot itself.
Set Transport Position: Before handling or transporting the robot, always set the Razor Spray Tool to the transport position. Move the Tool Plunger (1) to the 1st hole (the very top).

03 - Correct height setting for the Razor Spray Tool

04 - Spray from the fan nozzle will hit the center line of the disc when having the correct height.

3. Adjusting the Line Width (Disc Width)

The width of the discs (12) can be adjusted to create lines of 5 cm (≈2 in), 8 cm (≈3.1 in), 10 cm (≈4 in), or 12 cm (≈4.7 in) (see guide references below, Ill. 05).

05 - Line width options, looking at the width guides.

Important: After changing the line width, you must also adjust the nozzle height (See section 4. Adjusting the Nozzle Height).

Adjustment Procedure:

Power Down: Turn OFF the robot using the key on the battery.
Raise Tool: Use the Tool Plunger (1) to move the entire Razor Spray Tool to the very top hole on the robot.

06 - Tool Plunger - Used to adjust the height of the whole spray tool.

Lower Discs: Push the Push-Plunger (6) to release the disc mechanism, allowing the discs to be manually lowered all the way down.

07 - Push plunger can release the discs when the robot is turned off.

Open Lever: On one side (e.g., the left side), Open the Disc Lever (8).

08- Open the disc lever to adjust the line width.

Adjust Width:
- Slightly lift the Disc (12) to move it away from the Width Guides (13, 14).
- Slide the disc inward or outward along the slide rods to the approximate desired width.

09 - Discs move on the slide rods.

Lock Position:

Rotate the Disc (12) downwards, ensuring the Male Width Guide (14) correctly aligns and falls into the hole of the Female Width Guide (13).
Close the Disc Lever (8) to lock the disc position.
Check Tension: You should feel a slight resistance when closing the lever. If the disc can still move side-to-side, the lever screw may need tensioning (See section 5. Post-Tensioning the Disc Lever Screw).
- See Ill. 05 for width references

10 - Closing disc lever to lock disc position

Repeat: Repeat Steps 4 through 6 for the other side.

Stow Discs: Rotate the discs upwards until they click and lock into the upper position.

11 - Discs locked in upper position.

12 - Options for different line width configuration.

4. Adjusting the Nozzle Height

After setting your desired line width, you must adjust the Nozzle (11) height to ensure optimal spray coverage and line quality.

13 - Adjusting the nozzle height, Razor Spray Tool overview.

The Nozzle Assembly is held in place by the Twist Plunger (5).

Unlock: To move the Nozzle (11), Unlock the Twist Plunger (5) by turning it to Position 2 or Position 3.

14 - Twist plunger explanation

Slide: Once unlocked, the nozzle can slide freely up or down.

15 - Different nozzle height configurations.

Set Height: Set the nozzle height based on the disc width and nozzle type, using the guidelines in the table and figure below.
- Goal: The intersection point where the paint meets the discs should be 10 mm to 30 mm(≈0.4 to 1.1 inches) above the grass height.

16 - Correct nozzle height.

Note: Nozzle height must be adjusted to fit both grass height AND line width.

17 - Examples of correct and wrong nozzle height settings.

Lock: Always lock the Twist Plunger (5) after adjusting the nozzle height.

5. Post tensioning the Disc Lever Screw

If the Discs (12) can still move side-to-side even with the Disc Lever (8) locked, the Disc Lever Screw (15) needs to be tightened.

18 - Overview of disc lever tensioning.

Power Down: Turn OFF the robot using the key on the battery.

Stow Tool & Discs: Move the tool to the top position using the Tool Plunger (1) and swing the Discs (12) up until they lock in the top position.

19 - Discs locked in upper position.

Loosen Screw: Locate the Disc Lever Screw (15). Use a TX20 bit to loosen it all the way, while holding the Disc Lever (8) to counter the rotation.

20 - Location of disc lever screw - Tighten screw.

Apply Loctite: Remove the screw and apply a small amount of Loctite to the screw tip's thread.

21 - Disc lever screw.

Reinsert & Adjust:
- Reinsert the screw. Lightly tighten it with the TX20 bit.
- Hold the Disc Lever (8) in the locked (closed) position as you tighten the screw further.
- Test the mechanism: The lever should be able to unlock easily by hand and slide freely, and it should lock firmly by hand with the discs unable to slide back and forth.
- If the locking action isn't correct, tighten or loosen the Disc Lever Screw (15) by only a quarter (1/4) of a rotation and test again.

22 - Location of disc lever screw - Untighten screw.

Repeat & Cure: Repeat this procedure on the opposite side if necessary. Allow the Loctite to dry and cure before using the robot.

6. Adjusting Delay on the Discs

If your painted lines have defects (like uneven edges or smears) at the beginning or end of the line, it means the timing for the discs raising and lowering needs adjustment.

These adjustments are controlled on your tablet under: Settings > Robot Settings > Paint Settings. You will adjust two main controls: "Trim Discs Start" and "Trim Discs Stop."

23 - Adjust timing discs going up and down. Setting > Robot Settings > Paint Settings
