OPERATION
Lubrication
CAUTION:
Do not operate the chain saw when
the tank is empty. Replenish the oil in due time
before the tank is empty.
CAUTION:
Prevent the oil from coming into
contact with the skin and eyes. Contact with the
eyes causes irritation. In the event of eye contact,
flush the affected eye immediately with clear
water, then consult a doctor at once.
CAUTION:
Never use waste oil. Waste oil con-
tains carcinogenic substances. The contaminants
in waste oil cause accelerated wear of the oil
pump, the bar and the chain. Waste oil is harmful
to the environment.
