SAFETY RULES ON HOW TO AVOID KICKBACK
Kickback is a very sudden movement of the chain -
saw. It happens when the user cut an object with the
upper quadrant of the bar nose and the chainsaw bar
jumps off the object, towards the user. Kickback may
become very dangerous for the user and therefore,
be extremely cautious when limbing and avoid con -
tacting the log with the nose of the bar. Moreover,
be very cautious with the limbs under tension, since
they can move backwards and towards you like a
spring, which can cause you serious injury.
MAINTENANCE
WARNING
Before cleaning, inspecting or repairing
your unit, make sure that engine has stopped and is
cool. Disconnect the spark plug to prevent accidental
starting. Follow the instructions to carry out regular
maintenance, pre-operating procedures and daily
maintenance routines. Improper maintenance may re -
sult in serious damage to the machine.
