Levelling
before
Checking the accuracy of the levelling
Set the instrument on a tripod half-way between
two walls (A+B) that are approx. 5 m apart. Place
the lock switch in the "Unlocked" position (see
elling
lock). Direct the instrument at wall A and
switch on the instrument. Activate the horizontal
laser line or laser point and mark the position of
the line or the point on wall (A1). Rotate the instru-
ment by 180° and mark the horizontal laser line or
the laser point in exactly the same way on wall
(B1).
Then place the instrument at the same elevation
as close as possible to wall A and again mark the
horizontal laser line or the laser point on wall A
Lev-
(A2). Rotate the instrument by 180° again and
mark the laser on wall B (B2). Measure the dis-
tances of the marked points A1-A2 and B1-B2.
Calculate the difference of the two meas-
urements.
|(A1 - A2) - (B1 - B2)| <=2 mm
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.
