Safety InformationSafety Information
Attention Read the Manual
Improper installation, operation or maintenance of the
Connect Work Tools Equipment could result in serious
injury or death. Only qualied operators may operate the
Connect Work Tools equipment. Personnel responsible
for the maintenance of the Connect Work Tools
equipment or its systems, including inspection,
installation or adjustments must also be qualied.
Operators and personnel responsible for the
maintenance of this equipment should read this manual.
Other manuals, such as those published by the
machinery used in support of the Connect Work Tools
equipment, should also be read.
General Construction Safety
Always follow procedures that promote safe
conditions for workers and bystanders. e standard
safety precautions expected and required of those
working in construction shall include, but not limited to:
• Locating existing underground service and utility
lines
• Establishing pedestrian barriers
• Using personal protection equipment appropriate to
working conditions, etc.
Owner's Responsibilities
Ensure that only qualied personnel operate and service
the Connect Work Tools equipment.
Ensure personal protection equipment is available to
personnel and enforce the use of PPE.
Ensure that carriers are in safe, working order and all
guards and safety equipment is installed and in operating
condition.
Ensure safety-related materials such as instructions and
including this manual are kept in a convenient location
so that they are easily accessible to operators and
maintenance personnel.
Personal Protective Equipment (PPE)
Personnel operating or nearby the equipment and exposed
to the hazard of falling, ying and splashing objects, or
exposed to harmful dusts, fumes, mists, vapors, or gases
shall use the particular personal protective equipment
(PPE) necessary to protect them from the hazard. Such PPE
may include safety eyewear, face shield, hearing protection,
safety footwear, gloves and dust mask. Supervisors shall
review proper PPE selection and ensure PPE is made
available to personnel. Personnel are responsible for
wearing PPE as directed by the supervisor.
Construction equipment designed with guards shall have
guards in place when equipment is in use. Guards are tted
to the equipment to protect against unsafe situations that
could not be eliminated through design measures. Where it
was not possible to prevent an unsafe situation by means of
a guard, safety messages appear on the equipment, warning
personnel of a hazardous condition.
Guards shall not be removed unless for the purpose of
inspection and service of components. All guards must be
reinstalled aer service or adjustments are completed. Do
not operate the Connect Work Tools attachments without
guards.
Additional guarding, not included with the Connect Work
Tools equipment, is necessary at the operator's station to
protect the operator and other nearby personnel against
ying debris from material being cut or demolished. Do not
handle, demolish or cut material overhead without proper
guards installed.
To prevent accidental start up, the control switch shall be
located in a protected area that is guarded and makes it
dicult to accidentally operate the equipment.

General InformationGeneral Information
1. Introduction
Preface
is manual will provide an understanding of the Connect Work Tools Magnet by providing instructions for safe and
eective operation and instructions for regular maintenance activities of the magnet in addition to parts information.
Before installation or operation of the magnet for the rst time, please read and understand this manual.
e specications and designs presented in this manual are subject to change without prior notice.
2. Safety Precautions
Operation
• Operate the magnet for its intended purpose only.
• Operate the magnet only when the operator is seated in the cabin with full control of the machine.
• No bystanders are allowed in the vicinity of the magnet when it is operating. Debris can cause serious injury to by-
standers.
• Stay clear of the compactor when it is operating.
• Before operating the magnet, read and follow the safety decals located on equipment.
• Be sure that all decals are clearly visible. Clean and replace as necessary.
Protective Equipment
• Always wear the following personal protective equipment: safety glasses, ear protection, protective gloves and
protective shoes.
Heat Caution
• Never touch the hot parts. Wait for them to cool down rst if you have to touch them.
• Hot hydraulic oil can cause burns. Never use your ngers to check for hydraulic uid leaks and always keep your face
away from a possible leak.

Safety Precautions
Do not perform inspection or maintenance work when the engine of the carrier vehicle is running. It is required
that there be two qualied personnel to perform inspections. One of the personnel will operate the vehicle, and
the other person to check the operation of the magnet. During this inspection, do not touch the magnet or allow
any part of the body or clothing come into contact with it.
