Adjusting saw chain tension

CAUTION:
A chain which is too loose can
jump off the bar and it may cause an injury or
accident.
The saw chain may become loose after many hours
of use. From time to time check the saw chain tension
before use.
If the saw chain is loose, adjust the saw chain tension.

OPERATION

Lubrication
CAUTION:
Do not operate the tool 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 tool 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 tools 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.

To fill the oil, perform the following steps:
1. Clean the area around the oil tank cap thoroughly
to prevent any dirt from entering the oil tank.
2. Lay the tool on its side.
3. 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.

4. Fill the oil tank with the oil. The proper amount of
oil is 55 ml.
5. Screw the oil tank cap firmly back in place.
6. Wipe away any spilt chain oil carefully.
NOTE: If it is difficult to remove the oil tank cap, insert
the tip of slotted screwdriver into the slot of the oil
tank cap, and then remove the oil tank cap by turning
it counterclockwise.

After refilling, hold the tool away from the material to
be cut. Start it and wait until lubrication on saw chain is
adequate.

CAUTION:
Before the cutting operation, make
sure that the branch to be cut is in contact with
the root of guide bar and the support part of tool
body. Otherwise, the tool may be pulled toward the
tip of guide bar and the guide bar may wobble, and
may result in an injury.
