The Operator Manual
!MWARNING
You and others can be killed or seriously injured if you

understand anything, ask your employer or JCB
dealer to explain it.
INT-1-4-2
Do not operate the machine without an Operator Manual,
or if there is anything on the machine you do not
understand.
Treat the Operator Manual as part of the machine. Keep it
clean and in good condition. Replace the Operator Manual
immediately if it is lost, damaged or becomes unreadable.

Safety - Yours and Others
INT-1-3-1_3
All machinery can be hazardous. When a machine is
correctly operated and properly maintained, it is a safe
machine to work with. But 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 tell you of
potential hazards and how to avoid them. If you do not fully
understand the warning messages, ask your employer or
JCB distributor to explain them.
But 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 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 job until you are sure that you and those
around you will be safe.
If you are unsure of anything, about the machine or the job,
ask someone who knows. Do not assume anything.
Remember

General Safety
T1-043
!MWARNING
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 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.
INT-1-4-1
!MWARNING
Care and Alertness

Clothing
You can be injured if you do not wear the proper
clothing. Loose clothing can get caught in the
machinery. Wear protective clothing to suit the job.
Examples of protective clothing are: a hard hat, safety
shoes, safety glasses, a well fitting overall, ear-
protectors and industrial gloves. Keep cuffs fastened.
Do not wear a necktie or scarf. Keep long hair
restrained. Remove rings, watches and personal
jewellery.

Work sites can be hazardous. Inspect the site before
working on it. You could be killed or injured if the
ground gives way under your machine or if piled
material collapses onto it. Check for potholes and
hidden debris, logs, ironwork etc. Any of these could
cause you to lose control of your machine. Check for
utilities such as electric cables (overhead and
underground), gas and water pipes etc. Mark the
positions of the underground cables and pipes. Make
sure that you have enough clearance beneath
overhead cables and structures.

other people away. Do not perform new operations
until you are sure you can do them safely.
INT-2-1-1
!MWARNING
Airborne particles of light combustible material such
as straw, grass, wood shavings, etc. must not be
allowed to accumulate within the engine compartment
or in the propshaft guards (when fitted). Inspect these
areas frequently and clean at the beginning of each
work shift or more often if required. Before opening
the engine cover, ensure that the top is clear of debris.

Electrical Power Cables
You could be electrocuted or badly burned if you get
the machine or its attachments too close to electrical
power cables.
You are strongly advised to make sure that the safety
arrangements on site comply with the local laws and
regulations concerning work near electric power lines.
Before you start using the machine, check with your
electricity supplier if there are any buried power
cables on the site.
There is a minimum clearance required for working
beneath overhead power cables. You must obtain
details from your local electricity supplier.
2-2-5-4
!MCAUTION
