Waste oil is very dangerous for the environment.
Waste oil contains high amounts of carcinogenic substances.
Residues in waste oil result in a high degree of wear and tear 

at the oil pump and the sawing device.
In case of damage caused by using waste oil or unappropriate 

chain oil the product guarantee will be null and void.
Your salesman will inform you about the use of chain oil.

Mineral oil products degrease your skin. If your skin comes in 

contact with these substances repeatedly and for an extended 

period of time, it will desiccate. Various skin deseases may result. 

In addition, allergic reactions are known to occur.
Eyes can be irritated by contact with oil. If oil comes into your 

eyes, immediately wash them with clear water.
If your eyes are still irritated, see a doctor immediately!

If you are not planning to use the saw again for an ex-

tended period of time, empty the oil tank and put in a 

small amount of regular engine oil (SAE 30), and then 

run the saw for a time. This is necessary to flush out all 

remaining bio-degradable oil from the oil tank, oil-feed 

system, chain and guide bar, as many such oils tend to 

leave sticky residues over time, which can cause damage 

to the oil pump or other parts.

The next time you use the saw, fill the tank with BIOTOP 

chain oil again. In case of damage caused by using waste 

oil or unappropriate chain oil the product guarantee will be 

null and void.
Your salesman will inform you about the use of chain oil.

Be careful and cautious when handling fuels.
The engine must be switched off!
Thoroughly clean the area around the caps, to prevent dirt from 

getting into the fuel or oil tank.
Unscrew the tank cap (use the universal wrench if necessary, 

see illustration) and fill tank with fuel mixture or saw chain oil 

up to the bottom edge of the filling neck. Be careful not to spill 

fuel or chain oil! Be careful not to spill fuel or chain oil!
Screw on the tank cap by hand all the way.
After  refuelling,  clean  screw  cap,  tank  and  check  for  

Lubricating the chain                  
During operation there must always be sufficient chain oil in the 

chain-oil tank to provide good chain lubrication. One filling is 

sufficient for about one half-hour of continuous operation. During 

this procedure check whether there is enough the chain oil in 

the tank and refill if necessary. Do this only with the engine 

turned off! Screw on the tank cap by hand all the way.
