tripod through the holes at the center of
the Laser Level’s lower base.
2. Be sure to set the Laser on as flat a
surface as possible. The tri-brack
adjustment on the base of the level can
be used to help level the unit. (Turn each
of the knobs to either raise or lower that
corner.) The self-leveling range of the
Laser is within ± 6°. Use the 2 Vials on
the base to verify that the base is level.
6. Level the Laser by using the tri-brack
adjustment screws until the bubbles are
centered on the two levels.
7. Loosen the brass screw located under
the center of the Laser Level’s upper
base until the pendulum lock is released.
8. Turn on the Laser. Allow the laser lines
to stabilize for 4 to 6 seconds before
starting any measuring or leveling tasks.
9. To disassemble and store, follow the
above directions in reverse. please
note: Retighten the brass screw under
the Laser Level before continuing. This
will lock down the pendulum during
disassembly.
