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.
NOTICE:
When the chain saw is used for the first
time, it may take up to two minutes for the saw chain
oil to begin its lubricating effect upon the saw mech-
anism. Run the saw without load until it does so.
NOTICE:
When filling the chain oil for the first
time, or refilling the tank after it has been com-
pletely emptied, add oil up to the bottom edge of
the filler neck. The oil delivery may otherwise be
impaired.
NOTICE:
Use the saw chain oil exclusively for
Makita chain saws or equivalent oil available in
the market.
NOTICE:
Never use oil including dust and parti-
cles or volatile oil.
NOTICE:
When pruning trees, use botanical oil.
Mineral oil may harm trees.
NOTICE:
Before the cutting operation, make sure
that the provided oil tank cap is screwed in place.
Saw chain is automatically lubricated when the tool is in
operation. Check the amount of remaining oil in the oil
tank periodically through the oil inspection window.
