Accuracy Check
Vertical and horizontal line
Checking the accuracy of the horizontal line
Place the lock switch in the "Unlocked" position
(see Levelling lock). Position the instrument
approx. 5 m away from the wall. Direct the instru-
ment at the wall and switch on. Activate the laser
line and mark the intersection point of laser
crosshairs on the wall. Swivel the instrument to the
right and then to the left. Observe the vertical devi-
ation of the horizontal line from the marking. If the
difference does not exceed 3 mm, then the instru-
ment is within tolerance.

Checking the accuracy of the vertical line
Place the lock switch in the "Unlocked" position
(see Levelling lock). As a reference, use a plumb-
bob and attach it as close as possible to an approx.
3 m high wall. Position the instrument at a distance
of approx. 1.5 m from the wall at an elevation of
approx. 1.5 m. Direct the instrument at the wall
and switch on. Rotate the instrument and align it
with the bottom of the plumb line. Now read off the
maximum deviation of the laser line from the top of
the plumb line. If the difference does not exceed 2
mm, then the instrument is within tolerance.
Should your instrument be outside of the spe-
cified tolerance, please contact a local dealer
or an authorised Makita distributor.
