Suction Hose/Pickup Body

Impurities gradually clog the fine
pores of the filter with tiny particles of
dirt. This prevents the oil pump from
supplying sufficient oil to the bar and
chain. In the event of problems with
the oil supply system, first check the
oil tank and the pickup body. Clean
the oil tank if necessary.
