12 - Maintenance Safety
Introduction

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.

Air Conditioning Maintenance

The air conditioning system is a closed loop system

and contains pressurised refrigerant. No part of the

system  should  be  disconnected  until  the  system

has  been  discharged  by  a  refrigeration  engineer

or  a  suitably  trained  person.  You  can  be  severely

frostbitten or injured by escaping refrigerant.

Compressed Air

Compressed  air  is  dangerous.  Wear  personal

protective equipment. Never point a compressed air

jet at yourself or others.

Springs

Always  wear  personal  protective  equipment  when

dismantling  assemblies  containing  components

under pressure from springs. This will protect against

eye injury from components accidentally flying out.

Metal Splinters

You  can  be  injured  by  flying  metal  splinters  when

driving metal pins in or out. Use a soft faced hammer

or  copper  drift  to  remove  and  install  metal  pins.

Always wear personal protective equipment.

Communications

Bad  communications  can  cause  accidents.  If  two

or more people are working on the machine, make

sure  each  is  aware  of  what  the  others  are  doing.

Before starting the engine make sure the others are

clear of the danger areas. Examples of danger areas

are: the rotating blades and belt on the engine, the

attachments and linkages, and anywhere beneath or

behind the machine. People can be killed or injured

if these precautions are not taken.

Repairs

If  your  machine  does  not  function  correctly  in

any  way,  get  it  repaired  straight  away.  Neglect  of

necessary repairs could result in an accident or affect

your  health.  Do  not  try  to  do  repairs  or  any  other

type of maintenance work you do not understand. To

avoid injury and/or damage get the work done by a

specialist engineer.

Hydraulic Pressure

Hydraulic  fluid  at  system  pressure  can  injure  you.

Before connecting or removing any hydraulic hose,

residual  hydraulic  pressure  trapped  in  the  service

hose  line  must  be  vented.  Make  sure  the  hose

service line has been vented before connecting or

removing  hoses.  Make  sure  the  engine  cannot  be

started while the hoses are open.

'O' rings, Seals and Gaskets

Badly  installed,  damaged  or  rotted  'O'  rings,  seals

and  gaskets  can  cause  leakages  and  possible

accidents.  Renew  whenever  disturbed  unless

otherwise instructed. Do not use Triochloroethane or

paint thinners near 'O' rings and seals.

Arc Welding

To  prevent  the  possibility  of  damage  to  electronic

components,  disconnect  the  battery  and  the

alternator  before  arc-welding  on  the  machine  or

attached implements.
If the machine is equipped with sensitive electrical

equipment,  i.e.  amplifier  drivers,  electronic  control

units (ECUs), monitor displays, etc., then disconnect

them  before  welding.  Failure  to  disconnect  the

sensitive  electrical  equipment  could  result  in

irreparable damage to these components.
Parts of the machine are made from cast iron, welds

on cast iron can weaken the structure and break. Do

not weld cast iron. Do not connect the welder cable

or apply any weld to any part of the engine.
Always connect the welder earth (ground) cable to

the same component that is being welded to avoid

damage to pivot pins, bearings and bushes. Attach

the welder earth (ground) cable a distance from the

part being welded no more than 0.6m.

Counterweights

Your machine may be installed with counterweights.

They are extremely heavy. Do not attempt to remove

them.

Accumulators

The accumulators contain hydraulic fluid and gas at

high  pressure.  Prior  to  any  work  being  carried  out

on systems incorporating accumulators, the system

pressure  must  be  discharged  by  a  JCB  dealer,  as

the sudden release of the hydraulic fluid or gas may

cause serious injury or death.

Hot Components

Touching hot surfaces can burn skin. The engine and

machine components will be hot after the unit has

been running. Allow the engine and components to

cool before servicing the unit.

Soft Ground

A  machine  can  sink  into  soft  ground.  Never  work

under a machine on soft ground.
