Repairs

This tool complies with relevant safety requirements.
Repairs should only be carried out by qualified persons using
original spare parts; otherwise this may result in considerable
danger to the user.

Additional safety instructions for non-rechargeable
batteries

◆ Never attempt to open for any reason.

Warning! Laser radiation.

Do not look into the laser beam.

Do not view the laser beam directly with optical
instruments.

Refer to the laser product characteristics.

◆ This laser complies with class 2 according to

EN 60825-1:1 1994+A11. Do not replace a laser diode
with a different type. If damaged, have the laser repaired
by an authorised repair agent.

◆ Do not use the laser for any purpose other than projecting

laser lines.

◆ An exposure of the eye to the beam of a class 2 laser is

considered safe for a maximum of 0.25 seconds.
Eyelid reflexes will normally provide adequate protection.
At distances over 1 m, the laser complies with class 1 and
thus is considered completely safe.

◆ Never look into the laser beam directly and intentionally.

◆ Do not use optical tools to view the laser beam.

◆ Do not set up the tool at a position where the laser beam

can cross any person at head height.

◆ Do not let children come near the laser.

Additional safety instructions for pipe and wire detectors

◆ Do not use the tool to detect AC voltage in uninsulated,

exposed or free wires.

◆ Do not use the tool as a substitute for a voltmeter.

◆ Be aware that the tool may not always properly detect all

pipes and wires. The following conditions can cause
inaccurate results:

- Low battery

- Thick walls with thin pipes or wires

- Very thick walls

- Very deep wires or pipes

4

- Walls covered with metal

- Very humid conditions

- Shielded cables

◆ Before use, always test the tool by detecting a known

pipe or wire.

◆ If in doubt contact a qualified contractor.

Warning! This tool will not detect wires in circuits isolated
from the mains supply, cables operating at direct current (DC)
or wires used for telecommunication or computer systems.
Hidden wires (e.g. wall lights) may not be detected when
switches are in the off position.
Warning! This tool will not detect pipes of any other material
than metal.

◆ Push the on/off switch (1) up to switch the tool on.

◆ Move the tool as necessary to position the laser line.

◆ If necessary, hang the unit on the wall using the

appropriate insert.
Note: the laser lines will only be level if the tool is kept within
5° from vertical.

Using the detector function (fig. C)

Detecting live wires

Warning! Test the unit on a known source of AC current
before use.

◆ Make sure unit is away from area being scanned and any

other AC current source.

◆ Turn the sensitivity dial (2) clockwise until the LED

indicator (3) is on.

◆ Slowly turn the dial (2) counterclockwise until the LED

indicator (3) is off.

◆ Test the unit by holding it adjacent to a plug connected to

a live socket. Confirm the operation of the LED indicator (3).
The unit is now ready for use and is set to maximum sensitivity.

◆ While holding the unit with one hand place your other

hand on the surface close to the area being scanned.

◆ Move the tool slowly and smoothly across the surface

area, approaching from different directions.
When an AC source is located, the LED indicator (4) will blink
intermittently.

◆ After detecting the work area repeat the testing

procedure to confirm the operation of the unit.

Fitting and removing inserts

The marking/hanging insert is used to make a mark on the
level line or to hang the tool on a drywall board using the
drywall pin supplied. The keyhole insert is used to hang the
tool on other types of wall using a screw or nail. The spacer
insert is used to extend the laser line.

Fitting

◆ Place the insert into the holder from the back of the tool.

◆ Align the notches on the insert with the recesses in the

insert holder.

◆ Let the insert click into place.

Removing

◆ Keep the notches on the insert depressed.

◆ Push the insert out of the holder.

Detecting metal pipes

Warning! Test the unit on a known metal object before use.

◆ Make sure unit is away from area being scanned or any

other metal objects when preparing for use.

object. Confirm the operation of the LED indicator (3) and

the buzzer.
The unit is now ready for use and is set to maximum sensitivity.

◆ While holding the unit with one hand place your other

hand on the surface close to the area being scanned.

◆ Move the tool slowly across the wall, approaching from

different directions.
When a metal object is detected, the buzzer will sound and
the LED indicator (3) will come on.

◆ After detecting the work area repeat the testing

procedure to confirm the operation of the unit.

Hints for optimum use

◆ If you need to extend the laser line, use the spacer insert

as shown (fig. D).

◆ If because of the lighting conditions it is difficult to see

the laser line, you can use one of the inserts as shown to
enhance the line (fig. E).

◆ After detecting a hidden object, the sensitivity of the unit

can be gradually reduced to maximise the accuracy (fig. C).
Slightly turn the sensitivity dial counterclockwise and
continue to move the tool across the detected area from
different directions until the location of the hidden object
is more accurately defined.
