Start up
Inserting / replacing batteries
Refer to drawing {C} - slide the locking button
forward to unlatch the battery compartment. Open
the battery compartment cover and insert the
batteries true to side. Press the battery cover back
down until the lock engages.
The battery symbol {B, 9} lights up when the battery
voltage is too low. Replace the battery as soon as
possible.
• Insert the batteries true to side
• Only use Alkaline batteries
• Remove the batteries if the instrument will not be
used for a long period of time (to prevent corro-
sion)

Switching on/off
ON: Briefly press the ON - key {B,1}.
OFF: Press and hold down the OFF- key {B,1}.
Laser functions
Pressing the ON-key {B,1} activates the following
laser functions:
By pressing the ON-key {B,1} again, the previous
function status is repeated.
Self leveling and Lock-functions
The instrument automatically levels itself within the
specified grade range (Refer to "Technical data") .
Press the Lock switch {B, 3} in order to transport and
tilt the instrument beyond the self-leveling range.
When locked, the pendulum is fixed and the self-
leveling function is deactivated.
Pulse/Power mode
The instrument is equipped with a Power mode.
Switching on the instrument activates the Power
mode and the laser lines are bright and highly visible.
If the high visibility of the laser lines is not required
and if in addition energy should be saved, then
pressing the Pulse key {B, 2} activates the Pulse
mode.
To be able to detect the laser lines over long
distances (> 20 m) or in unfavorable lighting condi-
tions, a laser detector can be used. In Pulse mode,
the laser beam is also recognized over large distances
by the detector.
(Laser detector refer to accessories)
Applications
Examples of applications can be found on the outside
of the back cover of this User Manual.
Pressing the ON -
key {B, 1} activates
1 x laser crosshairs (horizontal
and vertical laser line)
2 x horizontal laser line
3 x vertical laser line

Checking the accuracy of the
Makita SK102
)Check the accuracy of your Makita SK102
regularly and particularly before important leveling
jobs.
Checking the accuracy of the leveling
Refer to drawing {J+ K}.
Set the instrument on a stand halfway between two
walls (A+B) that are approx. 5 m apart.
Set the Lock switch {B, 3} to the "Unlocked" ( )
position.
Point the instrument to wall A and switch the instru-
ment on with the Laser ON {B, 1} key . Activate the
laser crosshairs with the Laser ON {B, 1} key and
mark the point of intersection of the laser crosshairs
on the wall A (-> A1).
Rotate the instrument by 180° and mark the point of
intersection of the laser crosshairs on wall B (-> B1).
Then place the instrument at the same elevation as
close as possible to wall A and again mark the point
of intersection of the laser crosshairs on wall A (->
A2). Rotate the instrument by 180° again and mark
the point of intersection of the laser crosshairs on
wall B (-> B1). Measure the distances of the marked
points A1-A2 and B1-B2. Calculate the difference of
the two measurements. If the difference does not
exceed 2 mm, then the Makita SK102 is within the
range of tolerance.
| (A1 - A2) - (B1 - B2) | ≤2 mm
Checking the accuracy of the horizontal line
Refer to drawing {L}.
Place the Lock switch {B, 3} in the "Unlocked" ( )
position.
Position the instrument approx. 5 m away from the
wall. Point the instrument at the wall and switch the
instrument on with the Laser ON {B, 1} key . Activate
both laser lines with the Laser ON {B, 1} key and
mark the point of intersection of the laser crosshairs
on the wall.
Swivel the instrument to the right and then to the
left. Observe the vertical deviation of the horizontal
line from the marking. If the deviation does not
exceed 3 mm, then the Makita SK102 is within the
range of tolerance.
Checking the accuracy of the vertical line:
Refer to drawing {M}.
Place the Lock switch {B, 3} in the "Unlocked" ( )
position.
As reference, use a plumb bob and mount 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.
Point the instrument at the wall and switch the
instrument on with the Laser ON {B, 1} key . Activate
the vertical laser line with the laser ON {B, 1} key.
Swivel the instrument until the vertical laser line is
slightly above the ground on the plumb-bob. Now
determine the maximum deviation of the laser line to
the plumb bob over the entire length of the line.

If the deviation does not exceed 2 mm, then the
Makita SK102 is within the range of tolerance.
)Should your Makita SK102 be outside of the
specified tolerance, please contact an authorized
dealership.
Display notices
Falling below or exceeding the permissible
temperature range:
The laser switches off and the symbols (−) and (+)
start to flash.
Outside of the self-leveling range:
The laser switches off and the symbol of the function
used starts to flash.
Pendulum locked:
The laser beam is not levelled and the Lock symbol
{B, 7} lights up.
Care and operating notices
Do not immerse the instrument in water. Wipe off dirt
with a damp soft cloth. Do not use aggressive
cleaning agents or solutions. Treat the optical
surfaces with the same care that you would apply to
eyeglasses or a camera.
Severe vibrations or dropping the instrument may
damage it. Before starting it up, check the instrument
for possible damage. Regularly check the leveling
accuracy of your instrument.
Transport
To safely transport the instrument, set the Lock
switch {B, 3} to "Locked" ( ).
