SAFETY INFORMATION

S1 - 6

to the end of the fuelling operation to avoid possible

generation of sparks due to static electricity.
Use a truck or trailer to haul a failed machine. Should

it be necessary to tow it, provide for suitable danger

signals  as  required  by  the  local  norms  and

regulations and observe recommendations given in

the Operator's manual. Load/unload the machine on

firm level ground providing safe support to the wheels

of the truck or trailer. Use strong access ramps, with

adequate height and angle. Keep the trailer flatbed

free of mud, oil or slippery materials. Tie the machine

securely  to  the  trailer  and  block  carriages  and

upperstructure.
Never  align  holes  or  slots  using  your  fingers;

alwaysuse appropriate aligning tools.
Remove all sharp edges and burrs from re-worked

parts.
Use only approved and effectively grounded auxiliary

power sources for heaters, battery chargers, pumps

and  similar  equipment  to  reduce  electrical  shock

hazard.
Lift  and  handle  heavy  components  using  hoisting

devices of appropriate capacity. Ensure the parts are

supported by appropriate straps and hooks. 
Use lifting eyes provided to this aim. 
Pay attention to bystanders near the lifting area.
Never  pour  gasoline  or  diesel  fuel  into  open

containers.  Never  use  gasoline,  solvents  or  other

flammable  fluids  to  clean  parts.  Use  proprietary

certified non-flammable, non-toxic solvents only.
When  using  compressed  air  to  clean  parts,  wear

safety  glasses  with  side  shields.  Limit  pressure  to

max  2  bar,  in  accordance  with  local  and  national

safety regulations in force.
Do  not  run  the  engine  of  this  machine  in  closed

buildings without proper forced ventilation capable to

remove toxic exhaust gases concentrating in the air.
Do not use open flames as light sources to look for

leaks or inspect  anywhere on the machine.
Make sure that all mechanical tools provided are in

good  condition  at  all  times.  Never  use  tools  with

mushroomed or damaged heads. Always wear eye

protections with side shields.
Move with extreme care when working under, on  or

near the machine or its attachments. 
In case of attachment tests during which the engine

should be kept running, a qualified operator must sit

in the driver’s seat at all times while the mechanic is

at work. 
Keep hands and clothes far off moving parts.
Stop the engine and move the safey lever to the lock

position  before  starting  adjusting  or  repairing  an

assembly.
Do not carry out any work on the attachment without

prior authorisation. Observe maintenance and repair

procedures. 

In case of field service, move the machine to level

ground and block it. If work on an incline cannot be

avoided,  securely  block  the  machine  and  its

attachments. Move the machine to level ground as

soon as possible.
Do not twist chains and cables. Never use a twisted

chain or cable for lifting or pulling. Always wear safety

gloves to handle chains or cables.
Be sure chains and cables are firmly fastened and

that the anchor point is strong enough to withstand

the expected load.
Keep all bystanders clear of the anchor point, cables

or chains. Do not pull  or tow unless the operator’s

compartments  of  the  machines  involved  are  fitted

with proper guards against  cable or chain backlash.
Keep  the  maintenance  area  clean  and  dry  at  all

times. 
Clean immediately all water and oil spillage.
Do not pile up oily or greasy rags as they represent a

major fire hazard. Always store them in closed metal

containers.
Before starting the machine or its attachment, check,

adjust and lock the operator’s seat. Also ensure that

nobody  is  within  the  machine  or  attachment

operating  range  before  starting  or  operating  the

machine and/or its attachments. 
Sound the horn.
Rust inhibitors are volatile and flammable. 
Prepare  parts  in  well  ventilated  areas.  Keep  open

flames away. 
Do not smoke. 
Store containers in a cool well ventilated place where

they could not be reached by unauthorised people.
Do not carry loose objects in your pockets that might

fall unnoticed into open compartments.
Wear appropriate safety clothing such as hard hat,

safety  shoes  and  gloves,    safety  glasses    when

splinters or other particles may be ejected.
Wear  the  appropriate  welder’s  equipment  such  as

dark  safety  glasses  or  mask,  hard  hat,  protective

clothing,  safety  gloves  and  footwear  always  while

welding  or  arc-cutting.  Wear  dark  safety  glasses

when you are near a welding in progress.
Do  not  look  the  welding  arc  without  proper  eye

protection.
Become acquainted with all your jacking equipment

and their capacity. 
Ensure  that  the  jacking  point  on  the  machine  is

appropriate  for  the  load  applied.  Also,  be  sure  the

supports under the jack and between the jack and the

machine are appropriate and stable. 
Any  equipment  supported  by  a  jack  represents  a

possible  hazard.  Always  support  the  load  onto

appropriate  blocking  means  as  a  safety  measure

before proceeding with service or maintenance work,
