• 9. 1/4-20 Mounting Screw: Used with the bracket for mounting.
• 10. Magnetic Mount Bracket: Attaches the laser level to magnetic surfaces.
• 11. Magnets: Integrated into the mounting bracket for magnetic attachment.
• 12. Nail Mounting Keyhole: Slot on the bracket for mounting with a screw or nail.

NOTE: There are no user-serviceable parts inside.

Visual Description: Diagrams show SIDE, BOTTOM, FRONT, and BRACKET views of the laser level and its magnetic mounting bracket, with numbered callouts indicating each part.

Symbols on Instrument

The instrument features several symbols indicating its functions and safety information:

• WEEE: Indicates electronics disposal requirements.
• Hazardous laser radiation: A warning symbol indicating potential laser hazards.
• Laser Class 2: Indicates the laser is a Class 2 laser product.
• Warning or Caution: General warning symbol.
• Battery Polarity: Indicates correct battery installation.
• DO NOT stare into beam or view directly with optical instruments: A symbol showing an eye and binoculars with a line through them, warning against direct viewing of the laser.
• Read instructions: An information symbol (i) indicating to consult the manual.
• CE Conformité Européenne: Indicates compliance with European Economic Area directives.
• IP54: Indicates Ingress Protection rating, meaning dust and water resistant.

A side warning label is also present, detailing model number, product name, website, laser specifications, compliance information, and input voltage.

Operating Instructions

Turning Laser Beams On/Off

To turn the laser lines on, set the Power/Pendulum Lock/Unlock Switch (1) to the 'unlock' position. To turn the laser lines off, move the switch to the 'locked' position.

Visual Description: An image shows the laser level projecting bright green horizontal and vertical lines onto a wall. Text overlay reads "Lasers On".

Pendulum Slider Switch & Self-Leveling

The laser assemblies are mounted on a pendulum for automatic self-leveling. The Power/Pendulum Lock/Unlock Switch (1) must be in the 'unlocked' position for self-leveling to occur. If the instrument is tilted by more than 4° from the horizontal plane, the pendulum cannot self-level, and the active laser beams will flash to indicate this. Reposition the instrument on a more level surface for proper self-leveling function.

NOTE: After use, the Power/Pendulum Lock/Unlock Switch (1) must be placed in the 'Locked' position prior to storage.

Magnetic Mounting Bracket (10)

The instrument can be attached to the magnetic mounting bracket (10) using the 1/4-20 Tripod Mount (9). The bracket can be magnetically attached to ferromagnetic structures like steel studs, ducts, structural beams, and steel doors. It also features a keyhole (12) for mounting with a screw or nail to non-magnetic structures. Once mounted, the instrument can be rotated 360° on the bracket to direct the laser beams.

Visual Description: Two images show the magnetic mounting bracket. The top image shows the laser level attached to a vertical surface via the magnet. The bottom image shows the laser level attached using the keyhole slot.

Verifying Accuracy of Laser Lines

Horizontal Beam Left/Right Tilt

To check horizontal accuracy, position the instrument on the floor at a distance 'x' from a vertical wall. Project the beam and mark the vertical location 'a' on the wall. Rotate the instrument to the right and mark the vertical location 'b' on the wall. The maximum allowable distance (delta) between 'a' and 'b' is specified in the table.

Visual Description: Two diagrams illustrate this procedure, showing the laser projecting onto a wall from two different positions, with marks 'a' and 'b' indicating the beam's vertical positions and the distance 'x' from the wall.

Horizontal Beam Out-of-Plane Tilt

To check for out-of-plane tilt, position the instrument parallel to a wall and project a beam from left to right, marking locations 'a' and 'b' at distance 'x'. Then, position the laser on the other side of the wall and project the beam back through mark 'b' from right to left, marking position 'c'. The maximum allowable distance (delta) between 'a' and 'c' is specified in the table.

Visual Description: Two diagrams show the laser projecting onto a wall from two different positions, illustrating the setup for measuring out-of-plane tilt with marks 'a', 'b', and 'c'.

Vertical Beam Tilt

To check vertical accuracy, position the instrument on the floor 10' (3.05 m) from the center of a door opening. Project the vertical beam through the doorway, marking points 'a' and 'c' in the center of the opening. Mark point 'b' on the floor 10' (3.05 m) past the doorway. Move the device behind point 'b' and project the vertical laser line through points 'b' and 'a'. Measure the distance between point 'c' and the projected laser line (point 'd'). For the vertical height of the doorway (distance 'x'), the maximum allowable distance (delta) between 'c' and 'd' is specified in the table.

Visual Description: Two diagrams illustrate the vertical beam tilt test, showing the laser positioned relative to a doorway and measuring the vertical deviation.

Battery Replacement

When the laser lines flash 3 times within 1.5 seconds, followed by 30 seconds of solid laser lines, the batteries need replacement.

1. Loosen the Battery Door Screw (7) and Battery Compartment Door (6).
2. Remove and recycle two spent AA batteries.
3. Install new batteries, noting the correct polarity.
4. Close the Battery Compartment Door and secure it with the Battery Door Screw. Do not over-tighten.

Visual Description: A diagram shows the battery compartment, the door, the screw, and three AA batteries, illustrating their orientation and placement.

Cleaning and Storage

Cleaning

Ensure the laser level is turned off. Wipe it with a clean, dry, lint-free cloth. Do not use abrasive cleaners or solvents.

Storage

Remove the batteries if the instrument will not be used for a prolonged period. Do not expose the instrument to high temperatures or humidity. After storage in extreme conditions exceeding the specified limits, allow the laser level to return to normal operating conditions before use.
