Each LP4 is leveled individually at the factory prior to packaging and shipping. While in transit, some parts can become loose, resulting in a tilt of the laser head and a gap between it and the Electric Stand. The LP4 is designed with an easy-to-adjust Leveling Jig on the underside of the laser head to compensate for this occurrence.

The following tutorial is a guide for using the Leveling Jig to ensure optimal laser functionality. These adjustments can be done if your bracket is not flush with the Electric Stand or as part of your regular upkeep to maintain a level and balanced laser. We recommend starting this process from Step 1 as if you just took your LP4 out of the box to eliminate all other variables.

1. Preparation and Assembly

1.1 Base Plate and LP4 Unit Assemble

Follow the YouTube tutorial or detailed steps below to correctly assemble the LP4 base plate and LP4 unit: https://youtu.be/5fP42LVeJxc?t=48.

Place the Base Plate and Electric Stand on a clean flat surface. Open the toolbox, and take out the M4X10 screws and the M2.5 hexagonal wrench needed to assemble the base plate.

Note: Make sure that the bracket bolt is firmly tightened to the Electric Stand.

Match the electric stand to the top of the base plate in the proper orientation, and firmly attach the stand to the base plate by inserting and tightening 4 screws with the hexagonal wrench.

Turn the assembled Electric Stand over and place it on a flat surface.

Note: Make sure that your LP4 is on a flat and even surface, and use a gradienter (carpenter's level) to check the vertical and horizontal angles.

Align the Laser Unit with the bracket on the Electric Stand, and secure it by tightening the knob of the bolt embedded in the bracket.

Double-check to ensure that the bolt is firmly tightened and the LP4 unit is resting flat on the bracket with the outside edge of each aligned.

1.2 LP4 and Riser Add-on Assemble

Follow the detailed steps below or the YouTube tutorial to correctly assemble and use the Riser Add-on with your LP4 unit: https://youtu.be/sC1EUqjHW70?t=35.

After assembling the base plate as instructed above, take out your LP4 unit and the Riser Add-on.

Align the Riser Add-on with the connecting bolt in the Electric Stand Bracket and attach it by turning the knob clockwise until it is finger-tight.

Align the Laser Unit with the bolt at the end of the Riser Add-on so that it is perpendicular to the Electric Stand, and secure it by turning the knob clockwise until it is finger-tight.

Double-check to ensure the riser add-on's bolts are tightened, and there's no obvious space between the riser add-on and the LP4 unit. Ensure the edge of the riser add-on and that of the LP4 unit are aligned.

2. How to Balance/Level your LP4 Unit

With or without the Riser Add-on attached, follow the guide below on how to use the Leveling Jig to adjust the balance and level of your LP4 unit.

Note: Please always be mindful when handling your LP4 unit. Make sure to disconnect the power and take care not to touch or damage the lens.

2.1 Balancing your LP4 unit left to right.

Take the M2 hexagonal wrench out of the toolbox.
Place a gradienter horizontally on the unit's touch screen to check your unit's level. The air bubble should be directly in the center of the device. If not, use the hexagonal wrench to adjust the screw on the left side of the Leveling Jig, as described below.
While facing the machine, check which direction the air bubble is favoring.
If the bubble is on the right, turn the screw counterclockwise bit by bit until the air bubble is centered.
If the bubble is on the left, turn the screw clockwise bit by bit, until the air bubble is centered.

2.2 Balancing your LP4 unit forward to back.

While facing your LP4, place a gradienter vertically on the unit's touch screen in line with the handle.
Check which direction the air bubble is favoring and use the hexagonal wrench to adjust the screw on the right side of the Leveling Jig.
If the bubble is away from you, turn the screw counterclockwise bit by bit, until the air bubble is centered.
If the bubble is towards you, turn the screw clockwise bit by bit, until the air bubble is centered.

📝Summary Chart

Gradienter Placement	Bubble Position	Adjustment
Horizontally	To the left	Left Screw - Clockwise
Horizontally	To the right	Left Screw - Counter-clockwise
Vertically	To the back	Right Screw - Clockwise
Vertically	To the front	Right Screw - Counter-clockwise

Note: If the screw reaches its limit while adjusting the Leveling Jig, follow these steps:

① Double check the surface where you put the LP4 is flat;

② Remove your LP4 from the Electric Stand bracket;

③ Adjust the Leveling Jig so that it is screwed in and resting flat;

④ Re-attach your LP4 to the Electric Stand bracket and resume the adjustment steps described above.

3. Verifying your LP4 Balance & Level

Check the balance of your unit by placing a gradienter on the following parts of your LP4. Check that each area is level both horizontally and vertically.

The touch screen
The end of the handle
The far end of the LP4 unit
The center and four corners of the base plate

If each area is level, your LP4 is balanced and ready for use.
If one or more parts are not level, your unit is not properly balanced. Please revisit Step 1 to ensure that all of the components are properly assembled, and repeat Step 2 to fine-tune the LP4 and Electric Stand.

Note: If you are unable to satisfactorily level your LP4 after following all of the above steps, kindly contact us to request technical support or warranty service. support@laserpecker.com

Q&A

Q: I followed the tutorial, but my laser unit is still resting at a slight angle. Will this affect the quality and accuracy of my laser? If so, what should I do?

A: The purpose of the Leveling Jig is to adjust the position of the laser head component to make up for any external imbalances, such as a tilted bracket. Your laser should be balanced and in perfect working order after following the above instructions, even if a tilt or gap is still noticeable between the bracket and the Electric Stand.

Q: Is there any way I can totally tighten the bolt on the bracket to remove the gap so that it is flush with the stand?

A: The bracket secures the LP4 unit to the Electric Stand, allowing it to be raised and lowered depending on the appropriate laser focal distance for your project. To allow for free up and down movement, the bracket cannot be totally locked in flush against the Electric Stand, and a small gap will be visible. In some cases, the angle of the bracket and LP4 unit will be slightly tilted. The Leveling Jig was designed to adjust and compensate for this circumstance. So, even if your LP4 appears to be unlevel, it will easily be made accurate by adjusting the Leveling Jig.
