How to check the chain brake:

 

1) 

Turn off the motor. 

2) 

Hold the chain saw horizontally, release your hand 

from the front handle, tap the tip of the guide bar to a 
stump or piece of wood, and confirm brake operation. The 
level of operation varies according to the size of the bar. 
 

In case the brake is not effective, consult our dealer.

CUTTING

 

WITH

 

THE

 

CHAINSAW 

 

Before continuing with your work, read the section "For 
Safe Operation", it is recommended to practice cutting 
simple logs first. This also helps you get used to your 
unit. 
Always follow all safety regulations that may restrict the 
use of the machine. The chain saw should only be used 
to cut wood. Cutting other types of material is 

prohibited. Vibrations and kickback vary with different materials and the 
requirements of safety regulations will not be respected. Do not use the 

chain saw as a lever to lift, move or divide 
objects. Do not lock it on fixed supports. It is 
forbidden to install tools or applications on the 
PTO that are not specified by the manufacturer. 
It is not necessary to force the saw into the cut. 

Apply only light pressure while running the 
engine at full speed. 
Daily inspection is recommended before use and 
after dropping or other impacts to identify significant 
damage or defects. 
Loading the engine with the chain caught in a cut 

can damage the clutch system. When the saw chain 
is caught in the cut, do not try to force it out, but use 
a wedge or crowbar to open the cut..
