Functions of the saw chain lubrication system can
be checked as follows:
switch the machine on and hold the end of the •
cutting unit over the sheet of cardboard or paper
placed on the ground:
CAUTION: • Do not touch the ground with the
chain, keep a distance of ca. 20 cm. Should oil traces
increasingly appear on the cardboard or paper, this
is an evidence of the proper functioning of the saw
chain lubrication system. If oil traces do not appear,
even though the oil tank is full, please contact IVT
customer Service;
the amount of •
oil to lubricate the
saw chain (1) can
be adjusted with
the screw (28).
Turn the adjusting
screw (28) counter
clockwise to
increase the oil
feed, clockwise to
decrease it (see
also the legend on
the machine’s casing).
