18 - Operating Safety
Introduction

Training

Make sure that you have had adequate training and

that you are confident in your ability to operate the

machine safely before you use it. Practice using the

machine and its attachments until you are completely

familiar  with  the  controls  and  what  they  do.  With

a  careful,  well  trained  and  experienced  operator,

your machine is a safe and efficient machine. With

an  inexperienced  or  careless  operator,  it  can  be

dangerous. Do not put your life, or the lives of others,

at risk by using the machine irresponsibly. Before you

start to work, tell your colleagues what you will be

doing and where you will be working. On a busy site,

use a signalman.
Before doing any job not covered in this manual, find

out the correct procedure. Your local JCB distributor

will be glad to advise you.

Fuel

Fuel is flammable, keep naked flames away from the

fuel  system.  Stop  the  engine  immediately  if  a  fuel

leak is suspected. Do not smoke while refuelling or

working on the fuel system. Do not refuel with the

engine  running.  Completely  wipe  off  any  spilt  fuel

which could cause a fire. There could be a fire and

injury if you do not follow these precautions.

Machine Condition

A defective machine can injure you or others. Do not

operate a machine which is defective or has missing

parts. Make sure the maintenance procedures in this

manual are completed before using the machine.

Machine Limits

Operating the machine beyond its design limits can

damage  the  machine,  it  can  also  be  dangerous.

Do  not  operate  the  machine  outside  its  limits.  Do

not  try  to  upgrade  the  machine  performance  with

unapproved modifications or additional equipment.

Engine/Steering Failure

If the engine or steering fails, stop the machine as

quickly as possible. Do not operate the machine until

the fault has been corrected.

Exhaust Gases

Machine exhaust gases can harm and possibly kill

you or bystanders if they are inhaled. Do not operate

the machine in closed spaces without making sure

there  is  good  ventilation.  If  possible,  install  an

exhaust extractor. If you begin to feel drowsy, stop

the machine at once and get into fresh air.

Worksites

Worksites  can  be  hazardous.  Examine  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.

Communications

Bad  communications  can  cause  accidents.  Keep

people  around  you  informed  of  what  you  will  be

doing.  If  you  will  be  working  with  other  people,

make sure any hand signals that may be used are

understood by everybody. Worksites can be noisy, do

not rely on spoken commands.

Parking

An incorrectly parked machine can move without an

operator.  Follow  the  instructions  in  the  Operator's

Manual to park the machine correctly.

Banks and Trenches

Banked material and trenches can collapse. Do not

work or drive too close to banks and trenches where

there is danger of collapse.

Safety Barriers

Unguarded  machines  in  public  places  can  be

dangerous. In public places, or where your visibility

is reduced, place barriers around the work area to

keep people away.

Sparks

Explosions and fire can be caused by sparks from

the exhaust or the electrical system. Do not use the

machine in closed areas where there is flammable

material, vapour or dust.

Hazardous Atmospheres

This  machine  is  designed  for  use  in  normal  out

door  atmospheric  conditions.  It  must  not  be  used

in  an  enclosed  area  without  adequate  ventilation.

Do  not  use  the  machine  in  a  potentially  explosive

atmosphere, i.e. combustible vapours, gas or dust,

without first consulting your JCB dealer.

Regulations

Obey all laws, worksite and local regulations which

affect you and your machine.
