NOTICE:
When the chain saw 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 mechanism. 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 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.

Fig.19
If you cannot cut the timber right through with a single
stroke:
Apply light pressure to the handle and continue sawing
and draw the chain saw back a little; then apply the
spike bumper a little lower and finish the cut by raising
the handle.

Bucking
1.
Rest the bottom edge of the chain saw body on
the wood to be cut.

Fig.21
2.
With the saw chain running, saw into the wood
while using the rear handle to raise the saw and the
front one to guide it. Use the spike bumper as a pivot.
3.
Continue the cut by applying slight pressure to the front
handle, easing the saw back slightly. Move the spike bumper
further down the timber and raise the front handle again.
NOTICE:
When making several cuts, switch the
chain saw off between cuts.
CAUTION:
If the upper edge of the bar is used
for cutting, the chain saw may be deflected in
your direction if the chain becomes trapped. For
this reason, cut with the lower edge, so that the
saw will be deflected away from your body.
►
Fig.22
When you cut a wood under tension, cut the pressured
side (A) first. Then make the final cut from the tensioned
side (B). This prevents the bar from becoming trapped.

Limbing
CAUTION:
Limbing may only be performed by
trained persons.
A hazard is presented by the risk
of kickback.
When limbing, support the chain saw on the trunk if possible. Do
not cut with the tip of the bar, as this presents a risk of kickback.
Pay particular attention to branches under tension. Do
not cut unsupported branches from below.
Do not stand on the felled trunk when limbing.
Burrowing and parallel-to-grain cuts
CAUTION:
Burrowing and parallel-to-grain
cuts may only be carried out by persons with
special training.
The possibility of kickback presents
a risk of injury.
Perform parallel-to-grain cuts at as shallow an angle as
possible. Take an extra caution when carrying out the
cut as the spike bumper cannot be used.

Felling
CAUTION:
Felling work may only be per
-
formed by trained persons.
The work is hazardous.
Observe local regulations if you wish to fell a tree.
►

Felling area
— Before starting felling work, ensure that:
•
Only persons involved in the felling operation
are in the vicinity;
•
Any person involved has an unhindered path
of retreat through a range of approximately
45° either side of the felling axis. Consider the
additional risk of tripping over electrical cables;
