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.

Working Platform

Using  the  machine  as  a  working  platform  is

hazardous. You can fall off and be killed or injured.

Never  use  the  machine  as  a  working  platform

unless  with  approved  man-basket  or  man-crate  (if

applicable).

Machine Safety

Stop  work  at  once  if  a  fault  develops.  Abnormal

sounds and smells can be signs of trouble. Examine

and repair before resuming work.

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.

Travelling at High Speeds

Travelling  at  high  speeds  can  cause  accidents.

Always  travel  at  a  safe  speed  to  suit  working

conditions.

Hillsides

Operating  the  machine  on  hillsides  can  be

dangerous if the correct precautions are not taken.

Ground conditions can be changed by rain, snow, ice

etc. Check the site carefully. When applicable, keep

all attachments low to the ground.

Visibility

Accidents can be caused by working in poor visibility.

Use your lights to improve visibility. Keep the road

lights,  windows,  mirrors  and  cameras  clean  (when

fitted).
Do not operate the machine if you cannot see clearly.
Modification  of  the  machine's  configuration  by  the

user  (e.g.  the  fitting  of  large  and  non-approved

attachments)  may  result  in  a  restriction  of  the

machine visibility.

Hands and Feet

Keep your hands and feet inside the machine.
When using the machine, keep your hands and feet

clear  of  moving  parts.  Keep  your  hands  and  feet

within the operator compartment while the vehicle is

in motion.

Controls

You  or  others  can  be  killed  or  seriously  injured

if  you  operate  the  control  levers  from  outside  the

machine. Operate the control levers only when you

are correctly seated.

Passengers

Passengers  in  or  on  the  machine  can  cause

accidents. Do not carry passengers.

Fires

If your machine is equipped with a fire extinguisher,

make  sure  it  is  checked  regularly.  Keep  it  in  the

correct machine location until you need to use it.
Do not use water to put out a machine fire, you could

spread an oil fire or get a shock from an electrical

fire.  Use  carbon  dioxide,  dry  chemical  or  foam

extinguishers. Contact your nearest fire department

as quickly as possible.

Roll Over Protection

If the machine starts to roll over, you can be crushed

if you try to leave the cab. If the machine starts to roll

over, do not try and jump from the cab. Stay in the

cab, with your seat belt fastened.

Confined Areas

Pay  extra  attention  to  proximity  hazards  when

operating  in  confined  areas.  Proximity  hazards

include buildings, traffic and bystanders.

Safe Working Loads

Overloading the machine can damage it and make it

unstable. Study the specifications in the Operator's

Manual before using the machine.

Lightning

If you are inside the machine during a lightning storm

stay  in  the  machine  until  the  storm  has  passed.  If

you  are  outside  of  the  machine  during  a  lightning

storm  stay  away  from  the  machine  until  the  storm

has passed. Do not attempt to mount or enter the

machine.
If the machine is struck by lightning do not use the

machine until it has been checked for damage and

malfunction by trained personnel.
