CAUTION:
Carry out the procedure of install-
ing or removing saw chain in a clean place free
from sawdust and the like.
CAUTION:
Do not tighten the saw chain too
much.
Excessively high tension of saw chain may
cause breakage of saw chain, wear of the guide bar
and breakage of the adjusting dial.
CAUTION:
A chain which is too loose can
jump off the bar and it may cause an injury
accident.
The saw chain may become loose after many hours
of use. From time to time check the saw chain tension
before use.

OPERATION
Lubrication
Saw chain is automatically lubricated when the tool is in
operation. Check the amount of remaining oil in the oil
tank periodically.
To refill the tank, lay the chain saw on its side and
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.

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.
WORKING WITH THE CHAIN SAW
CAUTION:
The first time user should, as a
minimum practice, do cutting logs on a saw-horse
or cradle.
CAUTION:
When sawing precut timber, use a
safe support (saw horse or cradle). Do not steady
the workpiece with your foot, and do not allow
anyone else to hold or steady it.
CAUTION:
Secure round pieces against
rotation.
CAUTION:
Keep all parts of the body away
from the saw chain when the motor is operating.
CAUTION:
Hold the chain saw firmly with
both hands when the motor is running.
CAUTION:
Do not overreach. Keep proper
footing and balance at all times.
NOTICE:
Never toss or drop the tool.
NOTICE:
Do not cover the vents of the tool.
Bring the bottom edge of the chain saw body into
contact with the branch to be cut before switching on.
Otherwise it may cause the guide bar to wobble, result-
ing in injury to operator. Saw the wood to be cut by just
moving it down by using the weight of the chain saw.
