Use caution with the powerful magnets in EzDig mounting plates
The mounting plates used to secure the sensors to the excavator use extremely strong rare earth
magnets. They must be handled with care to avoid personal injury and damage to the magnets. Fingers
and other body parts can get severely pinched between two attracting magnets or other metal surface.
Use caution when removing the magnetic mounting plates from the carrying case. When handling them,
be aware of their strong attraction to any nearby steel surface (such as the other mounting plates or
metal back plates of the sensors).
Other warnings about rare earth magnets
Never allow rare earth magnets near a person with a pacemaker or similar medical aid. The strong
magnetic fields of the magnet can affect the operation of such devices.
The strong magnetic fields of rare earth magnets can also damage magnetic media such as credit cards,
magnetic I.D. cards, cassette tapes, floppy disks, video tapes or other such items. They can also
damage computer hard drives, televisions, VCRs, computer monitors and other CRT displays. Never
place rare earth magnets near electronic appliances.
Children should not be allowed to handle rare earth magnets as they can be dangerous. Small magnets
pose a choking hazard and should never be swallowed or inserted into any part of the body.
Rare earth magnets are brittle, and can peel, crack or shatter if allowed to slam together. Do not modify
or machine them. Eye protection should be worn when handling these magnets, because shattering
magnets can launch pieces at great speeds. They will lose their magnetic properties if heated above
80°C (175°F). Rare earth magnets should never be burned, as burning them will create toxic fumes.

SAFETY LABELS
The One-Dot Laser used for first-time setup is a Class 2 laser, manufactured to comply with
the international rules of safety IEC 60825-1, 2001. Although the power of the emission of the
beam is less than 5mW in Class 2, the following cautions are recommended:
• Do not stare directly at the beam
• Do not set up the laser at eye level
Safety Information: Laser
Introduction
Use the system to dig with an excavator to a desired depth and create a
leveled plane or to set a slope and create a tilted surface. Also use it to
determine reach, such as for the width of a trench.
All the digging information is referenced to the center of the bucket blade
(or teeth) and the depth value shown is the distance from the actual
teeth position to the target depth.
Sensors measure the angle of the boom, stick, and bucket. The
information is transmitted instantly to the cab display. LEDs tell you how
far to dig.
A simple one-time procedure allows the EzDig system to “learn” the
dimensions of your machine. That is how it constantly calculates, in real
time, where the bucket tip is in relation to the target depth.
Excavator rotation and movement
With EzDig, the operator has to dig “straight ahead” (only
moving the booms/bucket in and out).
After the target depth has been set, the chassis has to stay
stable. Any rotation of it may produce an error depending on the
inclination.
Rotation of the chassis can be compensated by using a fourth
sensor as a “pitch” sensor on the chassis. This will automatically
correct forward and backward tilting movements of your
machine as well as rotation, providing accurate depth
information.
Every time that the excavator tracks are moved, it’s necessary
to zero again the reference (target) depth on a previous point
or, depending on the setup, take the laser height again.

PRECAUTIONS
The product must not be disposed with household waste.
Dispose of the product appropriately in accordance with the national regulations in force in your country.
ELECTROMAGNETIC COMPATIBILITY (EMC)
Description
The term Electromagnetic Compatibility is taken to mean the capability of the product to function smoothly in an environment where
electromagnetic radiation and electrostatic discharges are present, and without causing electromagnetic disturbances to other equipment.
WARNING
Electromagnetic radiation can cause disturbances in other equipment. Although the product meets the strict regulations and standards which are
in force in this respect, the manufacturer cannot completely exclude the possibility that other equipment may be disturbed.
CAUTION
There is a risk that disturbances may be caused in other equipment if the product is used in conjunction with accessories from other
manufacturers, for example field computers, personal computers, two-way radios, nonstandard cables or external batteries.
Precautions:
Use only the equipment and accessories recommended by the manufacturer. When combined with the product,
they meet the strict requirements stipulated by the guidelines and standards. When using computers and two-way
radios, pay attention to the information about electromagnetic compatibility provided by the manufacturer.
CAUTION
Disturbances caused by electromagnetic radiation can result in erroneous measurements. Although the product meets the strict regulations and
standards within this respect, the manufacturer cannot completely exclude the possibility product may be disturbed by very intense
electromagnetic radiation, near radio transmitters, two-way radios or diesel generators.
Precautions:
Check the plausibility of results obtained under these conditions.
WARNING
If the product is operated with connecting cables attached at one of their two ends, for example, external supply cables, interface cables, the
permitted level of electromagnetic radiation may be exceeded and the correct functioning of other products may be impaired.
Precautions:
While the product is in use, connecting cables, for example product to external battery, product to computer, must be connected at both ends.
