Assembly
Inserting/Replacing the Batteries
This product requires 2 x AAA batteries.
To open the battery lid (10), open the latch (A) and open the door in the
direction shown (see figure 1). Insert the batteries provided, as illustrated
in the battery compartment.
Always replace all batteries at the same time. Only use batteries from one brand and
with the identical capacity.
Remove the batteries from the measuring tool when not using it for extended
periods. When storing for extended periods, the batteries can corrode and self-
discharge.
Operation
Initial Operation
• Protect the measuring tool against moisture and direct sun light.
• Do not subject the measuring tool to extreme temperatures or
variations in temperature. As an example, do not leave it in vehicles for
long periods in direct sunlight. In case of large temperature variations,
allow the measuring tool to adjust to the ambient temperature before
putting it into operation.
• Avoid shock and impact. Shock damage to the measuring tool can
impair its accuracy.
• Switch the measuring tool off during transport.

Switching On and Off
To switch on the measuring tool in line operation, push the On/Off switch
(1) forward. To switch on the measuring tool in point operation, push the
On/Off switch (1) back.
Immediately after switching on, the measuring tool sends a laser beam
out of outlet opening (5line operation) or (6point operation), depending
on the selected operating mode.
WARNING: Do not point the laser beam at persons or animals and do not look into
the laser beam yourself.
To switch off the measuring tool, push the On/Off switch (1) to the centre
position.
Do not leave the switched-on tool unattended and switch the tool off after use.
For best battery life always switch off the measuring device when not in use.
Levelling Functions
NOTE: The specified levelling accuracy applies for the alignment of the
laser beam with reference to the spirit levels (3and 4).
If spirit levels (3or 4) leak, soak up with appropriate absorbent material
and dispose of safely. Spirit levels contain flammable liquid that may
cause respiratory tract, eye and skin irritation.
Position the Tool (see figure 2)
For precise alignment using the spirit levels, the position of the tool is
important. The specified levelling accuracy is only achieved when the tool
is correctly positioned.
For horizontal alignment with spirit level (4): the laser outlet opening
for line operation (5) must be horizontal and the aluminium supporting
surface (2) of the measuring tool must face downward.
For vertical alignment with spirit level (3): the laser outlet opening for
line operation (5) must face upward and the aluminium supporting surface
(2) of the measuring tool must face sideward.
Alignment with Laser Line (Line Operation)
Fasten the measuring tool to wall holder (11), place it against a wall or flat
surface being used as datum via the three supporting points (7) or fasten
it to another magnetic surface with the magnets (9).
Note: Horizontal alignment with the laser line is only possible on the surface against
which the measuring tool was placed. Even when the measuring tool was aligned
with the spirit level, the laser line on a transverse wall does not necessarily run
horizontal, and is thus not suitable for levelling.
Vertical Alignment: The laser outlet opening for line operation (5) must
face upward and the aluminium supporting surface (2) of the measuring
tool must face sideward.
Vertically align the measuring tool with spirit level (3). As an example, you
can align top and base cabinets alongside the vertical laser line.
Alignment of reference points: Turn the measuring tool to any required
angle in order to align the laser line alongside your reference points. As
an example, this can be used to place vehicle moulding in relation to
other moulding or body points.
Projecting/Checking Heights via Laser point (Point Operation)
Place the measuring tool on the wall holder and horizontally align it. As an
example, you can use the laser point to align mouldings, stickers etc. to
a set height.
When turning, do not to touch the measuring tool, otherwise its position
could be changed.

Working with tripod (recommended): Align the laser beam to the
requested height.
Project or check the height at the target location.
Vehicle wheel alignment (Use with Gunson 77137 or 77141).
Horizontally align the measuring tool with spirit level (4).
Example 1: Checking initial alignment of the front wheel to the rear axle
after centralising the steering rack/box and prior to checking the tracking.
Example 2: Checking initial alignment of the rear wheels/axle to the front
wheels prior to setting the front tracking.
Checking Horizontal / Vertical Lines with the Spirit Levels
The measuring tool can also be used as a carpenter’s spirit level for
checking vertical and horizontal lines, for example to align a washing
machine or a refrigerator. Position the measuring tool with the aluminium
supporting surface (2) on the surface to be checked. When placing on
horizontal surfaces, the aluminium supporting surface (2) must face
downward, when placing against vertical surfaces, the laser outlet
opening for line operation (5) must face upward.
Working Advice
For marking out, always use the centre of the laser point or the laser line.
The size of the laser point as well as the width of the laser line will change
with distance.
Fastening/aligning with the wall holder: With the wall holder (13), the
measuring tool can be fastened as follows: Line operation: Place the
wall holder via its recess on the backside onto a screw head slightly
projecting out of a wall. Fasten the measuring tool with the magnets (9) to
the metal surface for line operation (12) of the wall holder. Turn the upper
part of the wall holder to align the measuring tool as required.
Point operation: Place the wall holder via a tripod mount onto the 1/4"
male thread of the tripod and screw the locking screw of the tripod
tight. Align the tripod roughly. When working without tripod, place the
wall holder on a surface that is as horizontal as possible. Position the
measuring tool with the aluminium supporting surface (2) facing down
on the wall holder. Attach it via the left magnet (9) (viewed from the front
side of the measuring tool) to the metal surface for point operation (13)
of the wall holder. Horizontally align the upper part of the wall holder
with adjusting screw (14) of the wall holder and spirit level (4) of the
measuring tool. Turn the upper part of the wall holder by 90° and repeat
the alignment.
Maintenance and Service
Maintenance and Cleaning: Store and transport the measuring tool only
in the supplied protective pouch. Keep the measuring tool clean at all
times. Do not immerse the measuring tool in water or other fluids. Wipe
off debris using a moist and soft cloth. Do not use any cleaning agents or
solvents. Regularly clean the surfaces at the exit opening of the laser in
particular, and pay attention to any fluff of fibres.
After-sales Service and Application Service: Our after-sales service
responds to your questions concerning maintenance and repair of your
product as well as spare parts.
Disposal: Measuring tools, accessories and packaging should be sorted
for environmentally-friendly recycling. Do not dispose of measuring tools
and batteries/rechargeable batteries into household waste.
Only for EC countries:
According to the European Guideline 2012/19/EU, measuring tools
that are no longer usable, and according to the European Guideline
2006/66/EC, defective or used battery packs/batteries, must be collected
separately and disposed of in an environmentally correct manner.
