OVERVIEW

ACCESSORY

REPLACE BATTERIES

Only use Milwaukee M12 rechargeable batteries.

FUEL GAUGE

After switch on the laser the fuel gauge will display the battery life

LOW BATTERY INDICATION

When the voltage is low, the laser switch to power safe mode.
The laser will blink in self leveling mode

The laser will blink in manual mode
From now on it is still possible to continue the work. When the voltage is too low, the laser and the LED will flash 4 times and it automatically shuts down.

TRACK CLIP

Fix the track clip with screws to a pillar. Or clamp the track clip to ceiling channels, racks….

WALL MOUNT & GREEN TARGET PLATE

Use the magnetic wall mount to fix the laser Or fix it with a screw or nail on a pillar to a wall or metallic structures or similar.

Turn the laser 330°. Use the adjustment knob for 10° pivot micro adjustment
Use the green target plate to improve visibility of the laser beam in unfavourable conditions and at greater distances.
Use the tripod mount to fix the laser on a tripod

WORKING IN SELF-LEVELING MODE

In self-leveling mode the laser will level itself in a ± 4° range and can project a horizontal plane and two vertical planes.

Place the laser on a solid flat vibration free surface or on a tripod.
Turn the rotation dial to: . Laser mode indicator LED will display Horizontal laser will be emitted.
The laser will generate 3 laser planes.
(A) horizontal laser plane
(B) vertival laser plane side
(C) vertical laser plane front
(D) The laser will generate cross planes when all planes are activated.
Choose the planes that you want to work with by pushing buttons.
If the initial level of the laser is beyond ±4° and the self-leveling mode is activated, the laser beams will flash
In this case reposition the laser.
Before moving the laser, turn the rotation dial to: .
This will lock the pendulum and protect your laser.

WORKING IN MANUAL MODE
