−
Make the back cut a little higher than the base cut
of the scarf. The back cut must be exactly
horizontal. Leave approximately 1/10 of the trunk
diameter between the back cut and the scarf.
The wood fibers in the uncut trunk portion act as a
hinge. Do not cut right through the fibers under
any circumstances, as the tree will otherwise fall
unchecked. Insert wedges into the back cut in time.
−
Only plastic or aluminum wedges may be used to
keep the back cut open. The use of iron wedges is
prohibited.
−
Stand to the side of the falling tree. Keep an area
clear to the rear of the falling tree up to an angle of
45 ° either side of the tree axis (refer to the "
felling area " figure). Pay attention to falling
branches.
−
An escape path should be planned and cleared as
necessary before cuts are started. The escape
path should extend back and diagonally to the rear
of the expected line of fall as illustrated in figure.

Always remove the battery cartridge from the tool and
overlap the guide bar with the guide bar cover before
carrying the tool. Also cover the battery cartridge with
the battery cover.
MAINTENANCE
CAUTION:
•
Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
•
Always wear gloves when performing any
inspection or maintenance.
•
Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may
result.
Sharpening the saw chain
CAUTION:
•
Always remove the battery cartridge and wear
safety gloves when performing work on the saw
chain.
008633
Sharpen the saw chain when:
−
Mealy sawdust is produced when damp wood is
cut;
−
The chain penetrates the wood with difficulty, even
when heavy pressure is applied;
−
The cutting edge is obviously damaged;
−
The saw pulls to the left or right in the wood. The
reason for this behaviour is uneven sharpening of
the saw chain, or damage to one side only.
Sharpen the saw chain frequently, but remove only
a little material each time.
Two or three strokes with a file are usually sufficient for
routine resharpening. When the saw chain has been
resharpened several times, have it sharpened in a
MAKITA specialist repair shop.
Sharpening criteria:
−
All cutter length must be equal. Cutters of differing
length prevent the chain from running smoothly,
and may cause the chain to break.
−
Do not sharpen the chain once a minimum cutter
length of 3 mm has been reached. A new chain
must then be fitted.
−
The chip thickness is determined by the distance
between the depth gauge (round nose) and the
cutting edge.
