Safety devices (e.g. cutting unit cover, housing, handle, engine switch) are in good technical condition and work 
properly;  

  

 

Before adjustment, cleaning, maintenance, switch off the engine. 

 

Do not use the device when other people, especially children or pets, are nearby. 

 

Do not start a damaged chain saw. 

 

Do not move the device with the engine running. 

 

Turn the chain saw off when: 

 

-

 

you leave the equipment unattended, 

-

 

before adjustment, 

-

 

before checking, cleaning or repairing the device, 

-

 

after hitting with a foreign object, 

-

 

before you clean, 

-

 

in the event of abnormal vibrations. 

 

PREPARATION 

 

Always wear solid footwear and long pants when working with the equipment, do not operate the device with bare feet or in 

sandals. 

 

Check  carefully  the  area  where  you  will  be  working  and  remove  all  stones,  branches,  wires  and  other  foreign  objects 

protruding from the ground that you might trip over during your work. 

 

In high grass, you may not notice obstacles (e.g. stumps, roots), so before starting work with the device, mark all obstacles 

hidden in the grass that cannot be removed. 

 

Before use and after falling or other impacts, inspect the saw to identify any significant damage that may affect safety. 

 

REMEMBER!

 Do not leave the chain saw uncontrolled. Never leave the chain saw turned on, as unintentional use may result, which 

may result in accidents. 

 

USEAGE 

 

Work only in daylight or in good artificial light. 

 

Do not work during rain, especially during a storm and in high humidity. 

 

Do not work in strong winds or other weather conditions that will cause the device to use a dangerous situation. 

 

It is important to have correct posture during work. In order not to bother excessively, frequent change of work position is 

recommended. 

 

Stop work every 15 minutes - rest is necessary. Tiredness and distraction can contribute to an accident. 

 

Keep your feet steady and keep balance during work. 

 

When working on a slope, make sure your legs are standing firmly. 

 

Do not work too long because of the possibility of tingling or numbness in the fingers and hands. If such symptoms occur, 

stop working. 

 

Attention! The device causes vibrations of the limbs during operation. The value of vibration acceleration is provided in the 

table  with  rated  data.  Prolonged  exposure  of  hands  to  vibration  for  several  months  or  years,  can  cause  the  white  toe 
disease, i.e. a decrease in limb temperature caused by ischemia. Symptoms such as tingling, numbness, hypersensitivity to 

cold should not be underestimated, see a doctor. 

 

Do not use the device with damaged covers or housings or without any protection. 

 

Start the saw engine as per the instructions. 

 

Check the chain saw brake for proper operation from time to time, as a malfunctioning brake may not disconnect the cutting 
chain movement in an emergency. 

 

Refuel after switching off the engine and after it has cooled down, as there is a risk of spillage and ignition from hot parts of 
the chain saw. 

 

Do not touch the chain saw with exposed body parts to avoid any possible burns. 

 

When working, hold the chain saw with both hands on the handles provided. 

 

Always adjust before cutting the chain brake lever by pulling it toward you. During operation, the safety brake is also a hand 

guard. 

 

Move the chain saw away from the material to be cut only when the saw chain is running. 

 

When cutting processed sawn timber or thin limbs, use a special support (goat). It is not allowed to cut several boards at the 
same time (stacked on top of each other) or materials held by a leg or held by another person.
