SAFETY INFORMATION

E265C-E305C

horn. Make sure that nobody is within the machine

operating range. Lower the attachment slowly. 
Securely block and lock the machine every time you

leave  it  unattended.  Return  keys  to  the  safe  place

previously  agreed  upon.  Perform  all  necessary

operations for stopping as detailed in the Operator's

manual.
Drive  the  machine  far  from  pits,  trenches,  rocky

hanging walls, areas with overhead electric lines, and

slopes before stopping it at the end of the working

day.
Move all controls to the position specified for machine

stopping.
Never park on an incline without accurately blocking

the machine to prevent unexpected movement.
Follow  stopping  instructions  contained  in  the

Operator's manual.

MAINTENANCE

Carefully read the Operator's manual before starting,

operating,  maintaining,  fuelling  or  servicing  the

machine in any manner.
Read all safety decals mounted on the machine and

observe  instructions  they  contain  before  starting,

operating,  repairing,  fuelling  or  servicing  the

machine.
Do  not  allow  unauthorised  personnel  to  repair  or

service the machine.
Follow  all  recommended  maintenance  and  service

procedures.
Do not wear rings, wrist watches, jewellery, loose or

hanging  garments,  such  as  ties,  torn  clothing,

scarves, unbuttoned or unzipped jackets that can get

caught in moving parts. Wear certified safety clothes

such as: hard hat, no-slip footwear, heavy gloves, ear

protection, safety glasses, reflector vests, respirators

when  required.  Ask  your  employer  about  safety

regulations in force and protective equipment.
Do not use controls or hoses as hand holds. Hoses

and controls are movable parts and do not provide

solid support. Besides, controls  may be inadvertently

moved  and  cause  unexpected  movement  of  the

machine or its attachments.
Do not jump on or off the machine. Always keep both

hands and one foot, or both  feet and one hand in

contact with steps and/or grab rails.
Never service the machine  with someone sitting  in

the driver’s seat, unless this person is an authorised

operator assisting in the maintenance being carried

out.

Keep the operator’s compartment, step plates, grab

rails and handles clear of foreign objects, oil, grease,

mud  orsnow  to  minimise  the  danger  of  slipping  or

stumbling. 
Clean  mud  or  grease  from  your  shoes  before

climbing on the machine or driving it.
Never  attempt  to  operate  the  machine  or  its

attachments from any position other than sitting in the

operator’s seat. 
Keep  the  driver’s  seat  free  from  foreign  objects,

especially if these are not secured.
Should it be necessary to move the attachment for

maintenance  purposes,  do  not  raise  or  lower  the

attachment from any other position than sitting in the

operator’s  seat.  Before  starting  the  machine  or

moving its attachment, sound the horn and require

that nobody remains near the machine. 
Raise the attachment slowly.
Always lock  all moving components or parts of the

machine  that  must  be  lifted  for  maintenance

purposes  using  adequate  external  means  as

required  by  local  and  national  regulations.  Do  not

allow  anyone to pass or stay near or below a raised

attachment. If you are not absolutely sure about your

safety, do not stay or walk under a raised attachment.
Do not place head, body, limbs, hands, feet or fingers

near  articulated  cutting  edges  deprived  of  the

necessary  guards,  unless  they  are  suitably  and

safely locked.
Never lubricate, repair or adjust the machine with the

engine  running,  except  when  this  is  specifically

required by the Operator's manual.
Do  not  wear  loose  clothing,  jewellery  near  rotating

parts.
When  service  or  maintenance  require  access  to

areas that cannot be reached from the ground, use a

ladder or step platform conforming to local or national

regulations to reach the working area. If such means

are not available, use machine grab rails and steps.

Always perform all service or maintenance work with

the greatest care and attention.
Shop and/or field service platforms or ladders should

be manufactured and maintained in accordance with

local or national safety regulations in force.
Disconnect  batteries  and  label  all  controls  to  warn

that  service  work  is  in  progress,  according  to  local

and national safety regulation requirements.
Block the machine and all attachments to be raised

according  to  local  and  national  safety  regulation

requirements.
Do not check or fill fuel tanks or install batteries near

burning or smoking materials and open flames due to

the presence of flammable vapours. 
The fuel  filler pipe nozzle must be constantly kept in

contact with the filler neck and this even before fuel

starts flowing in. Keep this contact from the beginning
