Safety
Safety - Yours and Others
All machinery can be hazardous. When a machine is correctly operated and maintained, it is a safe machine
to work with. When it is carelessly operated or poorly maintained it can become a danger to you (the operator)
and others.
In this manual and on the machine you will find warning messages, read and understand them. They inform
you of potential hazards and how to avoid them. If you do not fully understand the warning messages, ask your
employer or JCB dealer to explain them.
Safety is not just a matter of responding to the warnings. All the time you are working on or with the machine
you must be thinking of what hazards there might be and how to avoid them.
Do not work with the machine until you are sure that you can control it.
Do not start any work until you are sure that you and those around you will be safe.
If you are not sure of anything, about the machine or the work, ask someone who knows. Do not assume
anything.
Remember:
• Be careful
• Be alert
• Be safe.
Safety Warnings
In this manual and on the machine, there are safety notices. Each notice starts with a signal word. The signal
word meanings are given below.
The signal word 'DANGER' indicates a hazardous situation which, if not avoided, will result in death or serious
injury.
The signal word 'WARNING' indicates a hazardous situation which, if not avoided, could result in death or
serious injury.
The signal word 'CAUTION' indicates a hazardous situation which, if not avoided, could result in minor or
moderate injury.
The signal word 'Notice' indicates a hazardous situation which, if not avoided, could result in machine damage.
The safety alert system (shown) also helps to identify important safety messages in this manual and on the
machine. When you see this symbol, be alert, your safety is involved, carefully read the message that follows,
and inform other operators.

General Safety
Training
To operate the machine safely you must know the machine and have the skill to use it. You must abide by
all relevant laws, health and safety regulations that apply to the country you are operating in. The operator's
manual instructs you on the machine, its controls and its safe operation; it is not a training manual. If you are a
new operator, get yourself trained in the skills of using a machine before trying to work with it. If you don't, you
will not do your job well, and you will be a danger to yourself and others. In some markets and for work on certain
jobsites you may be required to have been trained and assessed in accordance with an operator competence
scheme. Make sure that you and your machine comply with relevant local laws and jobsite requirements - it
is your responsibility.
Care and Alertness
All the time you are working with or on the machine, take care and stay alert. Always be careful. Always be
alert for hazards.
Clothing
You can be injured if you do not wear the correct clothing. Loose clothing can get caught in the machinery.
Keep cuffs fastened. Do not wear a necktie or scarf. Keep long hair restrained. Remove rings, watches and
personal jewellery.
Alcohol and Drugs
It is extremely dangerous to operate machinery when under the influence of alcohol or drugs. Do not consume
alcoholic drinks or take drugs before or while operating the machine or attachments. Be aware of medicines
which can cause drowsiness.
Feeling Unwell
Do not attempt to operate the machine if you are feeling unwell. By doing so you could be a danger to yourself
and those you work with.
Mobile Phones
Switch off your mobile phone before entering an area with a potentially explosive atmosphere. Sparks in such
an area could cause an explosion or fire resulting in death or serious injury.
Switch off and do not use your mobile phone when refuelling the machine.
Lifting Equipment
You can be injured if you use incorrect or faulty lifting equipment. You must identify the weight of the item to
be lifted then choose lifting equipment that is strong enough and suitable for the job. Make sure that lifting
equipment is in good condition and complies with all local regulations.
Raised Equipment
Never walk or work under raised equipment unless it is supported by a mechanical device. Equipment which
is supported only by a hydraulic device can drop and injure you if the hydraulic system fails or if the control
is operated (even with the engine stopped).
Make sure that no-one goes near the machine while you install or remove the mechanical device.
Raised Machine
Never position yourself or any part of your body under a raised machine which is not correctly supported. If the
machine moves unexpectedly you could become trapped and suffer serious injury or be killed.
Lightning
Lightning can kill you. Do not use the machine if there is lightning in your area.
Machine Modifications
This machine is manufactured in compliance with prevailing legislative requirements. It must not be altered in
any way which could affect or invalidate its compliance. For advice consult your JCB dealer.

About the Product
Introduction
General
Before you start using the machine, you must know how the machine operates. Use this part of the manual
to identify each control lever, switch, gauge, button and pedal. Do not guess, if there is anything you do not
understand, ask your JCB dealer.
Name and Address of the Manufacturer
JCB Excavators Limited, Lakeside Works, Rocester, Uttoxeter, United Kingdom, ST145JP
Product Compliance
Your JCB product was designed to comply with the laws and regulations applicable at the time of its manufacture
for the market in which it was first sold. In many markets, laws and regulations exist that require the owner to
maintain the product at a level of compliance relevant to the product when first produced. Even in the absence
of defined requirements for the product owner, JCB recommend that the product compliance be maintained
to ensure safety of the operator and exposed persons and to ensure the correct environmental performance.
Your product must not be altered in any way which could affect or invalidate any of these requirements. For
advice consult your JCB dealer.
For its compliance as a new product, your JCB and some of its components may bear approval numbers
and marking's, and may have been supplied with a Declaration/Certificate of Conformity. These marking's and
documents are relevant only for the country/region in which the product was first sold to the extent that the
laws and regulations required them.
Re-sales and import/export of products across territories with different laws and regulations can cause new
requirements to become relevant for which the product was not originally designed or specified. In some cases,
pre owned products irrespective of their age are considered new for the purposes of compliance and may be
required to meet the latest requirements which could present an insurmountable barrier to their sale/use.
Despite the presence of any compliance related marking's on the product and components, you should not
assume that compliance in a new market will be possible. In many cases it is the person responsible for import
of a pre owned product into a market that becomes responsible for compliance and who is also considered
the manufacturer.
JCB may be unable to support any product compliance related enquiry for a product which has been moved out
of the legislative country/region where it was first sold, and in particular where a product specification change
or additional certification would have been required in order for the product to be in compliance.

Product and Component Identification
Machine
Your machine has an identification plate. The serial numbers of the machine and its major components are
marked on the plate.
The serial number of each major unit is also shown on the unit itself. If a major unit is replaced by a new one,
the serial number on the identification plate will be wrong. Either get a replacement identification plate from
your JCB dealer or simply remove the old number. This will prevent the wrong unit number being quoted when
replacement parts are ordered.
