OPERATION
Lubrication
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. To
refill the tank, lay the
chain saw on its side,
then push the oil tank cap, and then
remove the oil tank cap. The proper amount of
oil is 200 ml. After
refilling the tank, make sure
that the oil tank cap is tightened securely.

After refilling, hold the chain
saw away from the tree.
Start it and wait until lubrication on saw chain is
adequate. ► Fig.19
NOTICE: When filling the chain oil for the first
time, or refilling the tank after it has been
completely 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
particles or volatile oil.
NOTICE: When pruning trees, use botanical oil.
Mineral oil may harm trees.
