Lufkin LSL160
Horizontal self-levelling by magnetically-dampened pendulum system, vertical alignment via
adjustable base. Laser 635 nm, accuracy 2 mm / 10 m, dust and splash protected to IP 54.
Self-levelling range, 3.5° with tilt alarm. For all horizontal and vertical alignment work. The
plumb up vertical reference beam is suitable for dropping a perpendicular line or for aligning
partition walls. The wall/floor bracket can be used to level the unit vertically or fasten it to a
wall.
General safety instructions
Caution: Never look directly into the beam. Lasers must be kept out of reach of children.
Never intentionally aim the device at people. This
is a quality laser measuring device and is 100%
factory adjusted within the stated tolerance. For
reasons of product liability, we must also draw
your attention to the following: Regularly check
the calibration before use, after transport and
after extended periods of storage. We also wish
to point out that absolute calibration is only possible in a specialist workshop. Calibration by
yourself is only approximate and the accuracy of the calibration will depend on the care with
which you proceed.
Warranty:
The warranty period is two years from the date of purchase. The warranty covers all material
and manufacturing defects occurring during this time. The following are excluded from
warranty: Damage due to improper use (e.g. connection to an unsuitable power source, falling
onto a hard surface, etc); improper storage; normal wear and tear; minor defects not impairing
operation. Any tampering by unauthorized persons will render the warranty void. In the event
that you need to claim warranty, please return the complete device together with proof of
purchase to the place of purchase or to the Service and Shipping address on the back page.
Note: This product is a precision instrument that must be handled and treated with care.
Avoid shocks and impact. Always keep and carry in the case! Switch all lasers off and secure
the pendulum when not in use. For cleaning, use a soft cloth and glass cleaner.
Laser light !
Do not stare into the
beam or view directly
with magnifiers.

SensoLite is able to detect the laser beam up to
200m from laser. Move the SensoLite up and down
through the laser beam until the middle indicator
appears and the level indicating LED comes on.
Mark the measured height at the level reference
groove.
Note: The laser receiver has two
tolerance settings: Precision and
free-hand setting. Changeover
between the settings is done by
button (10).

Horizontal use of LSL160
• Set up the unit on a surface that is as level as possible or fasten it to a tripod.
• Turn the transport lock (G) in the arrow’s “Unlock” direction to its limit. This releases the
locking mechanism that protects the pendulum during transport.
• Press the On/Off button (A).
• Within its range of +/- 3,5°, the unit will level itself automatically and the prism head will
begin to turn.
• The speed of rotation can be changed with the selector button (B), H = 600 RPM, M = 400
RPM, L = 200 RPM.
Vertical use of LSL160
• Turn the transport lock (G) in the arrow’s “Lock” direction to its limit.
• Hook the vertical/wall bracket into its receptacle (O). To do this, the locking lever (L) must
be in its lower position and the bracket must latch audibly. To release the bracket, press the
locking lever (L) down.
• Align the unit with the adjustment foot (J) as indicated by the vertical spirit level (F).
• Press the On/Off button (A). The prism head will begin to rotate.
• The speed of rotation can be changed with the selector button (B), H = 600 RPM, M = 400
RPM, L = 200 RPM.
Note: Always unlock the transport lock when the LSL160 is being used for horizontal
levelling by turning the transport lock to its “Unlock” position. If the unit is currently
outside of its automatic levelling range (> 3,5°) , a warning signal will sound and the
prism head will not rotate. The unit must then be placed on a surface which is closer to
level. When in vertical use, the unit does not level itself automatically.

Gradient Mode:
• Turn the transport lock (G) in the arrow’s
“Lock” direction to its limit. Now the tilt
function is inactive and the unit cannot align
itself automatically.
• Press the On/Off button (A). The prism head
will begin to rotate.
• The speed of rotation can be changed with
the selector button (B), H = 600 RPM, M =
400 RPM, L = 200 RPM.
• Adjust the unit to the desired angle. Slope
angle can be set precisely and quickly with
the aid of the optional tilt plate, Part No.:
LTP1
Important: Horizontal levelling cannot be accomplished in gradient mode because the
unit cannot automatically level itself.
Note:
Regularly check the calibration before use, after
transport and after extended periods of storage.
Always make sure to control all 3 axes.

Operation of the LSL160
• Open the battery compartment (H), insert the batteries and connect the plugs to the sockets.
The plugs fit in the sockets in one position only (see pictures on right). Close the battery
compartment.
Charging the batteries
• Before using the LSL160, fully charge the batteries.
• Connect the battery charger/mains unit to a mains source
and plug into the socket (M). Please only use the charger/
mains unit supplied with the device. If a different one is
used, the warranty will become void.
• If the LED (Q) blinks constantly, either the batteries must
be exchanged or recharged.
The device can also be operated with standard alkaline
batteries (6 x type AA). Insert the batteries as shown by
the installation symbols. Ensure the polarity is correct.
Insertion of batteries in the SensoLite
• Remove the battery cover (9) and insert the batteries as shown by the installation symbol,
ensuring that the polarity is correct. Then replace the cover.
• To extend battery life, the receiver switches off automatically after about 5 minutes if not
used.
Note: Do not expose batteries to excessive heat such as sunshine, fire, etc. Dry batteries
must not be recharged. Used batteries must not be disposed of as household waste.
Please take them to a collection point for used batteries or for special waste. Ask your
local authority for further details.

Calibration Check
To check the calibration of the LSL160 Laser, place the Laser on a surface or preferably a tripod
approximately 10m from a wall or post with the control panel away from the wall or post.
1. Release the pendulum lock and switch on the Laser.
2. Mark the level point on the wall or post and label this point “A” using the detector.
3. Rotate the Laser on the surface or Tripod 180º. Be certain NOT to move or adjust the tripod. Mark
the level point on the wall or post and label this point “B”. You have now checked the “Y” axis.
The point half way between points “A” and “B” is true level. If “A” and “B” are 4mm apart or less then
no adjustment is required.
To check the “X” axis, rotate the level by 90º so that one of the sides is towards the wall or post.
4. Mark the level point on the wall or post and label this point “C”.
5. Rotate the Laser on the surface or Tripod 180º so that the other side is towards the wall or post. Be
certain NOT to move or adjust the tripod. Mark the level point on the wall or post and label this point
“D”. You have now checked the “X” axis. The point half way between points “C” and “D” is also true
level and should be the same as that noted for the “Y” axis above. If points “C” and “D” are 4mm apart
or less then no adjustment is required.To adjust the LSL160 remove the plastic cross recess screw in
the axis requiring adjustment. The “Y” axis is adjusted using a 2.5mm Allen key and adjust the “X” axis
screw using a 2mm straight blade screwdriver.
