Set Up 
• Place laser tool on a flat, stable surface.
• If using the auto levelling feature move the pendulum / 
transport lock to the unlocked position. The laser tool must 
then be positioned in its upright position on a surface that 
is within the specified compensation range.
• The laser tool can be placed in any orientation and be 
functional only when the pendulum / transport lock is in the 
locked position.
Mounting on an Accessories
• Position accessory in a place where it will not be easily 
disturbed and near the central location of the area to 
be measured.
• Set up the accessory as required. Adjust positioning to 
be sure accessory base is near horizontal (within laser 
tools compensation range).
• Mount the laser tool to the accessory using the 
appropriate fastening method to be used with such 
accessory / laser tool combination.
CAUTION: 
• Do not leave the laser tool unattended on an 
accessory without fully tightening the fastening 
screw. Failing to do so may lead to the laser tool 
falling and sustaining possible damage.
NOTE:
• It is best practice to always support laser tool with 
one hand when placing or removing laser tool from an 
accessory.
Operation
NOTE:
• See LED Descriptions for indications during operation.
• Before operating the laser tool always be sure to check the 
laser tool for accuracy.
• In Manual Mode, Self-Levelling is OFF. The accuracy of the 
beam is not guaranteed to be level.
• Laser tool will indicate when it is out of compensation 
range. Reference LED Descriptions. Reposition laser tool 
to be closer to level.
• When not in use, please be sure to power OFF the laser 
tool and place the pendulum lock in the locked position.
Power
• Press   to turn laser tool ON.
• To turn laser tool OFF, repeatedly press   until the 
OFF mode is selected OR  press and hold   for ≥ 3 
seconds to turn laser tool OFF while in any mode.
Mode
• Press   repeatedly to cycle through the available 
modes.
Self-Levelling / Manual Mode
(See figures  
C
 and  
F
) 
• The pendulum lock on the laser tool needs to be 
switched to the unlocked position to enable self-
levelling.
• The laser tool can be used with the pendulum lock in the 
locked position when it is required to position the laser 
tool at various angles to project non-level straight lines 
and/or points (where applicable).
Accuracy Check and 
Calibration
NOTE:
• The laser tools are sealed and calibrated at the factory to 
the accuracies specied. 
• It is recommended to perform a calibration check prior to 
its rst use and then periodically during future use.
• The laser tool should be checked regularly to ensure its 
accuracies, especially for precise layouts.
• When performing the accuracy checks, use as large of an 
area / distance as possible. The greater the area / distance, 
the easier to measure the accuracy of the laser. 
• Transport lock must be in the unlocked position to 
allow the laser tool to self-level before checking 
the accuracy.
