77-320 / 77-321
Level / Point Transfer
• Using the horizontal laser beam, establish a horizontal
reference plane.
• Position the desired object(s) until they are aligned with the
horizontal reference plane to ensure object(s) are level.
Square
• Using the vertical and horizontal laser beams, establish a
point where the 2 beams cross.
• Position the desired object(s) until they are aligned with
both the vertical and horizontal laser beams to ensure
object(s) are square.
Pulse Mode (See Figure
H
)
• Setting laser tool to pulse mode allows use with optional
laser detectors.
Manual Mode (See Figures
F
and
J
)
• Disables self-levelling function and allows laser unit to
project a rigid laser beam in any orientation.
Accuracy Check and
Calibration
NOTE:
• The laser tools are sealed and calibrated at the factory to
the accuracies specifi ed.
• It is recommended to perform a calibration check prior to
its fi rst use and then periodically during future use.
• The laser tool should be checked regularly to ensure its
accuracies, especially for precise layouts.
• Transport lock must be in the unlocked position to
allow the laser tool to self-level before checking
the accuracy.
