OPERATION
Lubrication
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 oil tank cap is tightened securely.
Saw chain is automatically lubricated when the tool is in
operation. Check the amount of remaining oil in the oil
tank periodically.
► Fig.29: 1. Oil tank
To refill the tank, place the tool on a flat surface, then push
the button on the oil tank cap so that the button on the other
side stands up, and then remove the oil tank cap by turning it.
The proper amount of oil is 160 ml. After refilling the tank,
make sure that the oil tank cap is tightened securely.

NOTE: If it is difficult to remove the oil tank cap,
insert the box wrench into the slot of the oil tank
cap, and then remove the oil tank cap by turning it
counterclockwise.
