FUEL HANDLING
General
Fuel
Gasoline
•Use good quality unleaded gasoline.
• The lowest recommended octane grade is 87 
((RON+MON)/2). If you run the engine on a lower octane 
grade than 87 so-called knocking can occur. This gives 
rise to a high engine temperature and increased bearing 
load, which can result in serious engine damage.
• When working at continuous high revs a higher octane 
rating is recommended.
Environment fuel

OPERATING
•Feed down the machine in line with the blade. Pressure 
from the side can damage the blade and is very 
dangerous.
• Move the blade slowly forwards and backwards to achieve 
a small contact area between the blade and the material 
to be cut. This reduces the temperature of the blade and 
ensures effective cutting.
Kickback
Kickback is the sudden upward motion that can occur if the 
blade is pinched or stalled in the kickback zone. Most 
kickbacks are small and pose little danger....

How to aviod kickback
Avoiding kickback is simple.
• The work piece must always be supported so that the cut 
stays open when cutting through. When the cut opens 
there is no kickback. If the cut closes and pinches the 
blade ther is always a risk of kickback.
• Take care when inserting the blade in an existing cut.
• Be alert to movement of the work piece or anything else 
that can occur, which could cause the cut to close and 
pinch the blade.
Transport and storage
