Before each use
Check that the chain oil pump functions correctly: direct the bar
towards a clear surface at a distance of about 20 centimetres;
after the machine has run for about a minute, the surface should
show clear traces of oil
.
Check that excessive strength is not needed for activating and
deactivating the chain brake. Also check that it is not activated
too easily and that it is not
blocked. Then check chain
brake function as follows:
release the chain brake, grip
the machine correctly and start
up the machine, activate the
chain brake by pushing the front
hand guard forward with the left
wrist or arm but without
removing the hand from the
handle
. If the chain brake is
working correctly, the chain
should be stopped immediately.
Check that the chain is
sharpened correctly, in good
working condition and that the
tension is correct. If the chain is
irregularly worn, or if the cutting
teeth are only 3 mm long, the
chain must be replaced
.
Clean the air vents regularly to
prevent motor overheating
.
Check that the switch and switch block function correctly (to be
performed with the chain brake released): press the switch and
the switch block and ensure that they return to idle position as
soon as they are released; check that it is impossible to press the
switch without activating the switch
block.
Check that the chain catcher and
the right hand guard are in correct
condition without any visible faults
such as damaged material.
Every 2-3 hours of use
Check the bar condition, if necessary

and the
guide grooves
carefully; If the
groove is worn or shows signs of deep
notching, it must be replaced.

injury and high energy consumption.
