to move the magnets. If it is found necessary to move the
groups of magnets, this should be done before mounting
the magnetic holder on the excavator.
1. Release the clamping screw with the aid of a ⁵/₁₆ "
(8 mm) hex key.
2. Slide the magnets to the desired position on the
tubular section.
3. Retighten the clamping screw to a torque of 11 Nm.
NOTE Mount the machine receiver between the two
groups of magnets.
6.6 Attaching the magnetic holder
NOTE
On a mini-excavator, the magnetic holder can be at-
tached to the side, the front or the rear of the excavator
arm. The magnetic holder is equipped with the appro-
priate recesses which allow it to be attached beneath
hydraulic lines or over welds.
1. Place the magnetic holder on a steel or iron surface.
Take care to ensure that the surface is flat and clean.
2. Determine the position on the machine at which the
receiver is to be attached. When doing so, take the
height of the rotating laser into account.
3. Bring the upper edge of the magnets into contact
with the mounting surface.
4. Move the lower magnets slowly toward the mounting
surface until contact is made and both groups of
magnets hold securely.
NOTE Some of the parts of the magnetic holder are
made of metal and may thus leave marks on some
surfaces.
NOTE In order to ensure a secure hold, both groups
of magnets must make full contact with the mounting
surface.
6.7 Securing the machine receiver
Position the machine receiver between the two groups
of magnets. Insert it through the hook and then tighten
the fastening screw by turning it in a clockwise direction.
It may be necessary to release the fastening screw by
turning it in a counterclockwise direction before it can be
tightened.
6.8 Removing the magnetic holder
1. Remove the machine receiver form the magnetic
holder.
2. Remove the magnetic holder from the mounting
surface.
6.9 Instructions for mounting the receiver on an
excavator
NOTE
When mounting the tool on an excavator or tractor excav-
ator, the excavator arm should be in a vertical or nearly
vertical position. The excavator arm should be brought
into a position that it can take up every time the pre-set
level is to be read. This position is subsequently known
as the "position for checking the level". The machine
receiver can be mounted on the excavator before or after
it has begun the excavation.
6.9.1 Mounting the machine receiver from within
the excavation 3
1. Excavate a small area to the desired height/depth.
Bring the excavator bucket into the "position for
checking the level" within the excavation.
2. Set up the rotating laser in a suitable position (out-
side the excavation) that allows optimum reception
of the laser beam and efficient operation of the
excavator and switch it on.
3. Attach the magnetic holder to the side of the excav-
ator arm at the height of the laser beam.
4. Insert the machine receiver in the magnetic holder
and then slide it up or down until the pre-set level
of the laser beam is indicated and then secure the
receiver in this position.
5. Begin the excavation. Check at regular intervals to
ensure that the height of the excavation is correct.
6.9.2 Mounting the machine receiver from outside
the excavation 4
1. Set up the rotating laser in a suitable position (out-
side the excavation) that allows optimum reception
of the laser beam and efficient operation of the
excavator and switch it on.
2. Bring the excavator bucket into the "position for
checking the level" outside the excavation.
3. Determine the setting-up distance (L= distance
between the laser
height/depth of the excavation).
4. Transfer the setting-up distance L to the excav-
ator arm (measuring from the tip of the teeth on
the excavator bucket (outside the excavation). Sub-
sequently mount the magnetic holder on the side of
the excavator arm at this height L.
5. Secure the machine excavator in the holder. In doing
so, the pre-set level should be positioned exactly at
the end of distance L.
6. Switch the machine receiver on and begin the ex-
cavation.
7. Check at regular intervals to ensure that the height
of the excavation is correct.
