Safety instructions 
  Warning:  This  machine  ha  been  conceived  for semiprofessional use.
Each  component  of  the  saw  may  become  a  source  of 
potential  danger  in  the  event  of  incorrect  use  or  poor 
maintenance. It is advisable to pay particular attention to 
the paragraphs preceded by the following words: 
Precautions 
Warning  of  the  possible  risk  of  serious  personal 
injury or damage to material, in the event of failure to 
comply with the instructions. 
TRAINING 
Read the instructions in this manual carefully. 
Before  using  the  chain  saw  you  must  become  familiar 
with the controls and learn how to stop the engine quickly. 
You must also learn how to use it correctly.  
Never allow minors or those who are not familiar with 
the instructions to use the chain saw. 
Use  by  minors  over  16  years  of  age  is  only  allowed  for 
the  purpose  of  learning  under  the  surveillance  of  an 
instructor. 
Do not use the chain saw: 
•  when there are bystanders, especially children or pets,  nearby.  Always check the distance of bystanders. 
The saw must only be used by one person; 
•  if  the  user  has  taken  medication  or  is  under  the 
influence  of  alcohol  or  drugs  that  could  impair 
reflexes or visual capacities; 
• when fatigued or feeling unwell; •  without  safety  devices,  such  as  the  front  guard (hand guard) or when these devices are damaged; • in  closed  or  poorly  ventilated  areas,  to  prevent highly toxic carbon monoxide from accumulating; 
Do not adjust the chain saw 
This  could  seriously  endanger  the  operator’s  safety, 
leading to the risk of accidents and serious injuries. 
Bear in mind that the owner or user is responsible for 
accidents or risks to third parties or to their property. 
When transporting the chain saw: 
•  switch  off  the  engine  or  in  any  case  trip  the  safety device,  chain  brake,  to  prevent  accidental  chain start-up; • always fit the chain catcher; •  transport  the  chain  saw  holding  it  only  by  the  front handle (handrail); •  avoid  contact  with  hot  surfaces  and  especially  with the silencer (danger of burns); •  point  the  guide  bar  to  the  rear  of  the  direction  in which you are travelling; •  when transporting the chain saw with a vehicle, place 
it  where  it  cannot  cause  danger  to  anyone  and  fix 
it  securely  to  prevent  it  from  falling  over,  leading  to 
possible damage and fuel spillage (fire hazard); • always switch off the chain saw when not in use. 
Do not create sources of danger either for others 
or yourself!    Always  switch  off  the  engine  before  filling  with 
fuel. 
•  Do  not  smoke  and  keep  away  from  naked  flames. Danger of fire and serious burns or death. •  Do not fill when the engine is hot. In this situation of 
high temperature, any remaining fuel could spill from 
the tank and catch fire. •  Take care over spraying caused by pressure forming in  the  tank.  Open  the  fuel  cap  slowly  to  allow 
pressure to be released gradually. •   Always fill in well ventilated places. •  Clean any traces of fuel from the chain saw and the 
place in which filling is carried out. Prevent fuel from 
coming  into  contact  with  clothing.  In  the  event  of 
contact change your clothing, as it is a fire hazard. •  After filling,  clamp  the  fuel  cap  tightly  and  check  the seal.  Do not start the saw if there is any leakage, as this could cause danger of serious burns. •  Do  not  start  up  the  saw  in  the  place  in  which  filling took place. 
Clothing. 
Clothing must be suitable and MUST NOT be in any way 
restricting for the user. •  Wear  snug-fitting  clothing  providing  protection against cuts. •  Do not wear scarves, shirts, jewellery or any hanging 
or loose accessories that could become caught in the 
chain  saw  or  in  objects  and  materials  present  in  the 
workplace. • Wear gloves, safety footwear with non-slip soles and goggles. Use ear protectors to protect hearing. •  During cutting operations wear the protective helmet 
fitted with visor and ear protectors. 
Your  dealer  can  provide  you  with  information  on  safety 
material and has high quality items to offer its customers 
maximum safety when working. 
Before starting up 
Before starting to use the chain saw check the following: • chain brake device operating and efficient; •   bar and chain fitted correctly; • correct chain tension; 
  the throttle lever and safety lever move freely, without  having  to  be  forced  and  when  released  they  return 
to  neutral  automatically  and  quickly.  It  must  not 
be 
possible  to  activate  the  throttle  lever  before  having 
released the safety lever; •  the Stop switch is functioning and easy to move; •  the electric cables, especially the high voltage cable  (spark  plug  cable)  are  in  good  condition  to  prevent 
any sparks that could cause fuel to ignite. Also check 
correct  connection  between  spark  plug  cap  and 
spark plug; •  the handles are fixed firmly to the saw and are clean and dry. 
Starting the engine •  Rest  the  chain  saw  on  the  ground  holding  it  down firmly. The left hand on the front handle and the right 
foot on the rear handle. 
GB-3 
						

							
•  Move the saw at least 3 metres away from the filling point before starting the engine. •  Check  that  there  is  no-one  in  the  range  of  action  of the saw. The chain saw must only be handled by one 
person. • Never start up the chain saw indoors. •  Never  direct  the  silencer,  and  hence  the  exhaust gases, in the direction of flammable materials. 
•  Check  the  minimum  speed  of  the  saw,  which  must not allow the chain to rotate. 
  Moreover,  after  acceleration  the  engine  must  return  quickly  to  the  minimum  speed  when  the  throttle  is 
released. 
  If this is not the case do not start to work, adjust the  minimum  speed  and  solve  these  problems.  (see 
paragraph “Setting carburation”). 
  Warning: checking and adjusting the carburettor  and  the  minimum  speed  is  the  only  operation 
performed with the engine running. •  Check  that  chain  lubrication  is  regular.  Oil  supply  to the  chain  indicates  that  the  oil  pump  is  functioning 
correctly. 
  WARNING  UNDER  NO  CIRCUMSTANCES  should  the  chain  saw  be  used  if  the  chain  is 
not  lubricated,  as  this  would  cause  irreparable 
damage to all cutting parts in a very short time! 
When working 
  When working comply with the following: 
•  work  in  daylight.  Visibility  is  essential  to  guarantee safety conditions; •  stand in a firm and steady position. Where possible, avoid  working  on  wet  or  slippery  ground  or  ground 
that is excessively rough or steep and does not allow 
the operator to work in a steady position. 
  The user is responsible for assessing potential risks of  the working ground and taking all precautions required 
to guarantee personal safety. 
•  Never  work  without  a  pawl.  This  is  especially important when felling. •  When working at a height: 
  a) only work on an elevating work platform 
  b) do not use ladders 
  c) do not climb on the tree 
  d) do not work in unstable positions 
  e) do not work above shoulder level 
  f) do not use only one hand. 
•  Always  walk  and  never  run  to  avoid  losing  balance. Always take care over obstacles. 
 Always put the chain saw into the safety position when moving around. 
•  Pay  attention  to  materials  projected  by  the  action 
of  the  chain.  This  occurs  above  all  when  the  chain 
comes into contact with foreign bodies (nails, stones, 
etc.). Never operate the chain saw with bystanders in 
the work area. •  Take  care  not  to  knock  hard  against  foreign  bodies; this  could  damage  the  cutting  parts:  if  this  occurs, 
switch off the saw and check for damage. 
•  Pay  attention  to  any  abnormal  noise  or  vibrations. 
If  this  occurs,  switch  off  the  saw  and  look  for  the 
cause. 
Felling and removing branches 
  Operations  to  fell  and  remove  branches  must  be performed  by  skilled  personnel,  trained  to  use  the 
chain saw in these difficult operations. 
•  Before  starting  felling  operations  for  the  first  time, practice cutting trunks placed on trestles, in a stable 
and  safe  position.  This  will  allow  you  to  become 
familiar with use of the saw. 
Before commencing felling operations also check: 
•  that there are no bystanders in the work area (with the exception of any others involved in the felling opera-tion); 
•  that  the  work  area  is  free  from  obstacles  that  could 
endanger the operator and any collaborators; •  escape  routes  free  from  obstacles  have  been established; •  the natural direction in which the tree is leaning and  consequently the area covered by the “falling” tree. 
•  that there are no strong winds; in this case postpone felling operations. 
In any case, do not work alone or in a remote spot as, in 
the event of an accident, your calls for help might not be 
heard by collaborators. 
•  Free the base of the trunk to be felled from any scrub,  branches or stones, as these could create dangerous 
situations and damage the cutting parts of the chain 
saw. •  Make a first undercut on the trunk on the side on which the tree has been planned to fall. This facilitates and 
partly  guides  the  tree  during  felling.  Then  cut  right 
through  the  trunk,  starting  from  the  opposite  side  of 
the tree. 
When the tree is falling take care over springback of the 
trunk or any splinters caused by the trunk breaking. 
•  When operating on felled trunks, if working on sloping  ground always stand above the tree to avoid danger 
caused by movement of trunks. 
Pay  particular  attention  to  the  position  of  felled  trees, 
especially on uneven ground. Assess possible inner ten
-
sions of the timber. Avoid getting the blade wedged in the 
wood. Be alert for springback. 
Removing branches 
Beware  of  kickback.  The  chain  saw  can  suddenly 
kick  back  towards  the  operator.  Avoid  this  dangerous 
situation: 
• do not cut using the tip. •   do not lodge the tip of the bar in the wood – only cut  one  branch  at  a  time  –  only  cut  with  the  chain  saw 
running at maximum speed •  remove  any  branches  or  foreign  bodies  from  the cutting area •   hold the saw firmly with both hands. • stand in a stable position •  use chains with reduced tendency to kick back.
