The Makita SK103P is a self-leveling cross-line laser designed for various indoor and outdoor applications, providing precise horizontal and vertical laser lines and points. This device is engineered for ease of use and accuracy in professional settings.
Function Description:
The SK103P projects visible laser beams to assist with alignment, leveling, and plumbing tasks. It features a keypad with an On/Set key, Pulse key, and Lock switch for controlling its functions. The device offers multiple laser configurations, including horizontal line, vertical line, cross-lines (horizontal and vertical), all points, and all lines and points.
The self-leveling function automatically levels the instrument within its specified grade range. When the Lock switch is engaged, the pendulum is fixed, deactivating the self-leveling function, which is useful for transport or for projecting tilted lines. The Pulse mode allows the use of a laser detector for detecting laser lines over long distances (up to 60 meters) or in unfavorable lighting conditions.

- Display Indicators:
- Locked: Indicates the pendulum is locked.
- Laser Active: Shows when the laser is emitting beams.
- Pulse/Power Save Mode ON: Indicates the device is in pulse mode or power-saving mode.
- Self-levelling and Lock Functions:
- The instrument automatically levels itself.
- Turn the Lock switch (3) to fix the pendulum for transport or to project tilted lines.
- Pulse Mode: Enables the use of a laser detector for extended range and visibility in bright conditions.
- Wall Mount Bracket: The device can be attached to a wall mount bracket, which can be screwed into a surface or magnetically attached to metal studs.

- Installing cabinets and shelves
- Aligning tiles and flooring
- Installing drop ceilings
- Staircase layout
- Plumbing and squaring
- Display Notices:
- Temperature Range: If the temperature falls below or exceeds the permissible range, the laser switches off, and all symbols flash.
- Outside Self-levelling Range: The laser beam flashes.
- Pendulum Locked: The laser beam is not leveled, and the Lock symbol (4) lights up.
Maintenance Features:
Regular checking of the device's accuracy is crucial, especially before important measuring tasks.
- Checking Horizontal Line Accuracy:
- Place the instrument 5 m from a wall in "Unlocked" position.
- Mark the intersection point of laser crosshairs (A1).
- Swivel the instrument to the right and left, observing the vertical deviation of the horizontal line.
- The difference should not exceed 3 mm.
- Checking Vertical Line Accuracy:
- Place the instrument 1.5 m from a 3 m high wall in "Unlocked" position.
- Use a plumb-bob as a reference.
- Align the laser line with the bottom of the plumb line and read the maximum deviation from the top.
- The difference should not exceed 2 mm.
- Checking Vertical Plumbing Accuracy:
- Set up the laser near point A1 (min. 1.5 m from B1).
- Align the horizontal laser in direction 1, marking A1 and B1.
- Rotate the instrument by 180° to point in direction 2.
- Adjust the instrument so the laser beam hits A1 exactly.
- If point B2 is no further than 2 mm from B1, the SK103P is within tolerance.
- General Care:
- Do not immerse the instrument in water.
- Wipe dirt with a damp soft cloth.
- Avoid aggressive cleaning agents or solvents.
- Treat the instrument with care to prevent damage from dropping or violent shaking.
- Regularly check the leveling accuracy.
- Battery Handling:
- Only use chargers recommended by Makita.
- Flat batteries must not be disposed of with household waste; dispose of them at designated collection points.
- Transport: Set the Lock switch (3) to "Locked" for safe transport.
