SAFETY INFORMATION

E265C-E305C

likely to be concealed by bushes,   undergrowth and

such.
Avoid bushes, logs and rocks. Never drive over them,

nor  over  any  other  surface  irregularities  that

discontinue  adherence  or  traction  with  the  ground,

especially near slopes or drop-offs.
Be  alert  to  avoid  changes  in  adherence  conditions

that could cause loss of control. Work with extreme

care on ice or frozen ground  and on stepped slopes

or near drop-offs.
The  word  “bulldozing”  generally  refers  to  work  in

virgin rough terrain, characterised by the presence of

all the perils and risks listed above. We emphasise

the danger represented in these conditions by large

tree limbs (possibly falling on the machine) and large

roots  (which  may  act  as  a  leverage  under  the

machine  when  up-rooted  and  cause  the  unit  to

overturn).
Position the machine  dependent   upon the loading

and  unloading  areas  in  order  to  swing  leftwards  to

load to obtain best visibility.
Never use the bucket or attachment as a man lift or

carry  riders.  Never  use  the  machine  as  a  work

platform  or  scaffolding.  The  machine  must  not  be

improperly  used  for  works  not  consistent  with  its

features  (such  as    pushing  railway  cars,  trucks  or

other machines).
Always  pay  attention  to  people  within  the  machine

operating range. 
Never move or  stop  the  bucket,  other loads or  the

attachment above ground personnel or truck cabs.
Ensure  the  truck  driver  is  in  a  safe  place  before

loading the truck.
Load trucks from side or rear.
Use  only  the  type  of  bucket  recommended

considering machine type, materials to be handled,

material piling up and loading characteristics, ground

type  and other typical  conditions of  the  work  to be

performed.
When    transporting  a  loaded  bucket,  keep    it  as

rolled-back as possible. Keep boom and arm as  low

as possible. 
Ground speed should be adequate to the load and

ground conditions.
The load must always be properly  arranged in the

bucket;  move  with  extreme  care  when  transporting

oversize loads.
Do  not  lift  and  move  the  bucket  overhead  where

persons are standing or working, nor downhill when

working on a slope as this would decrease machine

stability. Load the bucket from the uphill side.
Loads  to  be  raised  using  the  machine  should  be

exclusively hooked to the hitch specially provided.
The excavator is no lifting and transportation means,

therefore  it  should  not  be  used  to  position  loads

accurately. Should it be exceptionally used to lift and

lay  building  components,  special  caution    must  be

taken as follows:

- The machine must be equipped compulsorily with

the appropriate variant provided upon request.

- Secure  the  loads  to  be  raised  using  cables  or

chains  fastened  with  appropriate  hooking

mechanisms.

- Nobody  should  be  allowed  to  remain  under  the

raised load or within the excavator operating range

for any reason whatever.

Never  exceed  specified  loading  capacity.  Incorrect

fastening of  slings  or chains  may cause  boom/arm

failure or failure of the lifting means with consequent

bodily  injuries and even death.
Always ensure that slings and chains used for lifting

are adequate to the load and in good condition.
All loading capacities are referred to the machine on

a    level  surface  and  should  be  disregarded  when

working on a slope.
Avoid  travelling  across  slopes.  Proceed  from  uphill

downhill  and  vice-versa.  If  machine  starts  slipping

sideways  when  on  a  slope,  lower  the  bucket  and

thrust bucket teeth into the ground.
Working on slopes is dangerous. Grade the working

area if possible. Reduce work cycle time if it is not

possible to grade the working area.
Do not move full bucket or a load from uphill downhill

as this would reduce machine stability. Do not work

with the bucket turned to the uphill side.
Do  not  work  with  the  bucket    turned  uphill  as

counterweights  protruding  downhill  would  reduce

machine  stability  on  the  slope  and  increase  risk  of

overturning.
We  recommend  to  work  on  slopes  with  the  bucket

downhill,  after  checking  machine  stability  with  the

bucket   empty  and attachment retracted, by  slowly

swinging the upper structure by 360°.
Position  the  carriage  at  a  right  angle  relative  to

slopes, hanging walls, etc. to exit the working area

easily.
Keep  the  machine  sufficiently    far  from  the  ditch

edge.
Never dig under the machine.
Should  it  be  necessary  to  dig  under  the  machine,

always  ensure  that  digging  walls  are  opportunely

propped up against  landslide to prevent the machine

from falling into the trench.
Do  not  swing  the  upperstructure,  raise  the  load  or

brake  abruptly    if    not  required.  This  may  cause

accidents.
Prior  to  beginning  the  work  near  gas  distribution

mains or other public utilities:
