  When not in use put the chain saw down in such a manner that there is no risk of 

injury. 

  Switch the device off, wait for the chain to come to a complete standstill and 

disconnect the spark plug before setting, servicing, cleaning, transportation or 
storage. 

  Always use the chain cover when transporting the chain saw. 

  Hold the chain saw firmly when starting. The chain and bar must be free. 

  Before starting work ensure that you are standing firmly. 

  Never cut with the tip of the bar 

– the chain saw may recoil (“kick-back”) 

  Do not use the chain saw near combustible gases or dust 

– danger of explosion. 

  Always ensure all handles and guards are fitted when using the chain saw. Ensure all 

screws and nuts are properly tightened before use. 

  Only operate this chain saw once correctly and fully assembled. 

  Switch the chain saw off immediately if you notice any changes in the machine. 

  Always have a first-aid kit at hand in case of accidents. 

  If the chain comes into contact with soil, stones, nails or other foreign objects, stop 

the chain saw immediately and check the chain as well as the bar. 

  Never leave the chain saw unsupervised. 

  Ensure that no chain oil penetrates into the soil or sewage. Always place the chain 

saw on something that will absorb any oil dripping from the bar or chain. 

  Stop the engine and disconnect the spark plug if the chain saw becomes blocked. 

  Never remove any of its components and never use a damaged or incomplete 

machine. Never modify any of the machine components. 

  Do not use your petrol chain saw for any jobs other than those for which it was 

intended. 

  WARNING: Petrol and its vapours are highly flammable. Always stop the engine 

before refuelling. Do not smoke or light any flames while refuelling. Wipe off any fuel 
that may have spilled. Refuel in a well ventilated area and never in closed 
environments. Start the engine away from the place where it was refuelled. Ensure 
the tank cap is tightened properly. Return the chain saw to its normal operating 
position before starting. 

  CAUTION: Exhaust fumes are toxic and asphyxiating. Inhalation may be lethal. Do 

not start the engine in closed or poorly ventilated environments. 

  If the chain becomes jammed or blocked by obstacles, switch the engine off 

immediately and visually inspect the chain saw for damage. Note, if the chain saw is 
damaged, repairs and servicing must only be performed by authorised dealers and 
service agents. 
 

D) 

Warning: Danger of recoil (“kickback”) 

 

WARNING:

 While the engine is running, 

kickback

 may occur when the nose or tip of 

the guide bar touches an object, or when the wood closes in and pinches the saw 
chain in the cut. Top contact in some cases may cause a lightning fast reverse 
reaction, kicking the guide bar up and back towards the operator. Pinching the saw 
chain along the top of the guide bar may push the guide bar rapidly back towards the 
operator. Either of these reactions may cause the operator to lose control of the saw 
which could result in the chain saw being flung upwards at high speed towards the 
person holding the chain saw and causing serious personal injury. 

 

Do not rely exclusively on the safety devices built into your saw. As a chain saw user 
you should take several steps to keep cutting jobs free from accident or injury:
