INTRODUCTION

ABOUT THIS HANDBOOK

Machine Model

This handbook provides information for the 4CX military
Backhoe Loader machine.

Using this Handbook

The illustrations in this handbook are for guidance only.
Where the machines differ, the text and/or the illustration
will specify.

This handbook is arranged to give you a good
understanding of the machine and its safe operation. It
also contains maintenance information and specification
data. Read this handbook from front to back before using
the machine for the first time. Particular attention must be
given to all the safety aspects of operating and
maintaining the machine.

Units of measurement

In this handbook, the S.I. system of units is used. For
example, liquid capacities are given in litres. The Imperial
units follow in parenthesis () eg 28 litres (6 gal).

Using the machine

To use the JCB Backhoe Loader efficiently and safely you
must know the machine and have the skill to use it. This
handbook instructs you on the machine, its controls and
its safe operation. It is not a training manual on the art of
excavating or loading. If you are a new operator, get
yourself trained in the skills of using a JCB Backhoe
Loader 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.

Left Side, Right Side

In this handbook, 'left' A and 'right' B mean your left and
right when you are seated correctly in the machine. This is
so whether you are facing the loader (front) or the backhoe
(rear).

INTRODUCTION

THE JCB BACKHOE LOADER

Machine Description

The backhoe loader is a self propelled wheeled machine with a main structural support designed to carry both a front
mounted bucket loading mechanism and a rear mounted backhoe. When used in the backhoe mode, the machine normally
digs below ground level with bucket motion towards the machine; the backhoe lifts, swings and discharges material while
the machine is stationary. When used in the loader mode, the machine loads or excavates through forward motion of the
machine, and lifts, transports and discharges material.

INTRODUCTION

SAFETY - YOURS AND OTHERS

All construction and agricultural equipment can be
hazardous. When a backhoe loader 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 handbook 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.

Fluoroelastomeric Materials

Certain seals and gaskets (e.g. crankshaft oil seal) on JCB
machines contain fluoroelastomeric materials such as
Viton, Fluorel and Technoflon. Fluoroelastomeric materials
subjected to high temperatures can produce highly
corrosive hydrofluoric acid. THIS ACID CAN SEVERELY
BURN.

New fluoroelastomeric components at ambient
temperature require no special safety precautions.

Used fluoroelastomeric components whose temperatures
have not exceeded 300°C require no special safety
precautions. If evidence of decomposition (e.g. charring) is
found, refer to the next paragraph for safety instructions
DO NOT TOUCH COMPONENT OR SURROUNDING
AREA.

Used fluoroelastomeric components subjected to
temperatures greater than 300°C (e.g. engine fire) must be
treated using the following safety procedure. Make sure
that heavy duty gloves and special safety glasses are
worn:

1 Ensure that components have cooled then remove

and place material into plastic bags.

2 Thoroughly wash contaminated area with 10%

calcium hydroxide or other suitable alkali solution, if
necessary use wire wool to remove burnt remains.

WARNING

Jacking

A machine can roll off jacks and crush you unless the
wheels have been chocked. Always chock the wheels at
the opposite end of the machine that is to be jacked. Do
not work underneath a machine supported only by jacks.
Always support a jacked-up machine on axle stands
before working underneath it.

INT-3-2-8

!!

WARNING

Under no circumstances must the engine be run with the
transmission in gear and only one driving wheel jacked
clear of the ground, since the wheel on the ground will
move the machine.

INT-3-1-16

!!

CAUTION

Rams

The efficiency of the rams will be affected if they are not
kept free of solidified dirt. Clean dirt from around the rams
regularly. When leaving or parking the machine, close all
rams if possible to reduce the risk of weather corrosion.

INT-3-2-10

!!

CAUTION

Arc Welding

Before carrying out arc welding on the machine,
disconnect the battery and alternator to protect the
circuits and components.

The battery must still be disconnected even if a battery
isolator is fitted.

Make sure that the welding earth return path is kept as
short as possible. This prevents high currents being
induced in the machine chassis or wiring harnesses.

If the machine is equipped with amplifier drivers or
electronic control units (E.C.U.s), then disconnect them
before welding. Failure to disconnect the amplifier drivers
or E.C.U.s could result in irreparable damage to the
electronic components.

Machine Identification Plate

Your machine has an identification plate mounted on the
loader tower. The serial numbers of the machine and its
major units are stamped on the plate.

The serial number of each major unit is also stamped 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 stamp the new number of the unit on the
identification plate, or simply stamp out the old number.
This will prevent the wrong unit number being quoted
when replacement parts are ordered.

The machine and engine serial numbers can help identify
exactly the type of equipment you have.

OPERATION

8642 - 1

The aim of this part of the handbook is to guide the
operator step-by-step through the task of learning how to
operate the machine efficiently and safely. Read the
OPERATION section through from beginning to end.

Before starting the machine, sit in the drivers seat and
familiarise yourself with the layout of the cab. Use your
handbook to identify each control lever, switch, gauge,
button and pedal. Do not guess. If there is anything you
do not understand, ask your JCB distributor.

The operator must always be aware of events happening
outside the cab as well as inside the cab. Safety must
always be the most important feature when operating the
JCB Backhoe Loader.

The following checks should be made each time you
return to the machine after leaving it for any period of time.
We advise you also to stop the machine occasionally
during long work sessions and do the checks again.

All these checks concern the serviceability of the machine.
Some concern your safety. Get your service engineer to
check and correct any defects.

! WARNING

Walking or working under raised attachments can be
hazardous. You could be crushed by the attachments
or get caught in the linkages.

Lower the attachments to the ground before doing
these checks. If you are new to this machine, get an
experienced operator to lower them for you.

If there is nobody to help you, study this handbook
until you have learned how to lower the attachments.
Also make sure that the parking brake is engaged
before doing these checks.

2-2-1-1

1 Check for Cleanliness

a Clean the windows, light lenses and rear view

mirrors.

b Remove dirt and debris, especially from around

the linkages, rams, pivot points and radiator.

c Make sure the cab step and handholds are clean

and dry.

d Clean all safety decals. Replace any that are

missing or cannot be read.

When you have familiarised yourself with the operating
controls, gauges and switches, practice using them. Drive
the machine in an open space, clear of people. Get to
know the 'feel' of the machine and its driving controls.

Finally, do not rush the job of learning, make sure you fully
understand everything in the OPERATION section. Take
your time and work efficiently and safely.

Remember

BE CAREFUL

BE ALERT

BE SAFE

2 Check for Damage

a Inspect the machine generally for damaged and

missing parts.

b Make sure that the bucket is secure and in good

condition

c Make sure that all pivot pins are secured correctly

in place.

d Inspect the windows for cracks and damage.

Steer Mode Selector Switch

This is a three-position rotary switch, equipped with a
hinged lockplate. The lockplate enables the selector
switch to be locked into the 2-wheel steer mode, when the
machine is driven on public roads.

Indicator lights on the instrument panel tell you what steer
mode the machine is in. If you have any doubt about the
steer mode the machine is in, always remember that it is
the indicator light which is correct.

Never change steer mode on the move, the machine
should be stationary. Only change the steer mode when
the engine is at low engine rpm/idling. Never change from
4 wheel steer to crab steer (or vice versa) without first
selecting 2 wheel steer for approximately 5 seconds (as
shown by the decal A).

1 2-Wheel Steer

The front wheels only are controlled by the steering
wheel. This position must be used for driving on
public roads. Make sure the hinged lockplate is
engaged.

2 4-Wheel Steer

The front wheels steer one way and the rear wheels
steer in the opposite direction. This position provides
the tightest turning circle.

3 Crab Steer

The front and rear wheels steer in the same direction.
This position improves manoeuverability in confined
spaces.

Re-phasing the Steer System

4 Wheel Steer Machines Only

! WARNING

Failure to phase 4-wheel steer at least once per day
may mean a reduction in steering effectiveness.

5-2-1-6

The steering must be re-phased:

i At the start of each working period

ii At least once per day.

ii If having difficulty in steering.

Follow the procedures below for re-phasing the steer
system:

1 Select 2-wheel steer.

Sensors on the axles prevent the steer mode from
changing until the wheels straighten up or pass
through the 'straight ahead' position. Because of this,
there will be a short period when the indicator lights
do not agree with the switch position.

2 Operate the machine until the rear wheels

straighten up.

When the rear wheels straighten up the machine will
go into 2-wheel steer. The indicator light will show
when 2-wheel steer has engaged.

3 Select 4-wheel steer again

The front and rear wheels are now back in phase.
