OPERATION

Lubrication
Fig.11
Saw chain is automatically lubricated when the tool is in
operation.
Check the amount of remaining oil in the oil tank through
the oil inspection window.
To refill the tank, remove the cap from the oil tank
opening. The oil tank capacity is 80 ml.
After refilling the tank, always screw the provided oil tank
cap on the chain saw.
CAUTION:
When filling the chain saw with 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.
As a saw chain oil, use oil exclusively for Makita
•
chain saws or oil available in market.
Never use oil including dust and particles or
•
volatile oil.
When pruning trees, use botanical oil. Mineral oil
•
may harm trees.
Never force the chain saw when pruning trees.
•
Before cutting out, make sure that the provided oil
•
tank cap is screwed in place.
Hold the chain saw away from the tree. Start it and wait
until lubrication on saw chain is adequate.
Bring the tip guide/lower guide into contact with the
branch to be cut before switching on. Cutting without
bringing the tip guide/lower guide into contact with the
branch may cause the guide bar to wobble, resulting in
injury to operator.
Saw the wood to be cut by just moving it down.
