Chain Lubrication

11.1 Pickup Body/
Suction Hose
Impurities gradually clog the fine
pores of the filter with minute
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.
