Working With The Tool; Carrying Tool; Sharpening The Saw Chain - Makita EY403MP Manual De Instrucciones

Saw chain is automatically lubricated when the tool is in
operation. Check the amount of remaining oil in the oil
tank periodically.
► Fig.13: 1. Oil tank
To refill the tank, place the tool on a flat surface, then 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.
The proper amount of oil is 160 ml. After refilling the tank,
make sure that the oil tank cap is tightened securely.

NOTE: If it is difficult to remove the oil tank cap,
insert the box wrench 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 tree. Start it
and wait until lubrication on saw chain is adequate.

Working with the tool

CAUTION:
Keep all parts of the body away
from the saw chain when the motor is operating.
CAUTION:
Hold the tool firmly with both
hands when the motor is running.
CAUTION:
Do not overreach. Keep proper
footing and balance at all times.
CAUTION:
When cutting through branches,
be careful not to lose your balance due to the
weight of the tool head.
CAUTION:
Always keep escape route in case
a cut branch falls towards the operator.
CAUTION:
Never use the tip of the guide bar
for cutting. Otherwise, dangerous kickback may
occur, and it may result in personal injury.
NOTICE:
Never toss or drop the tool.
NOTICE:
Do not cover the vents of the tool.
NOTICE:
Do not force the tool. Otherwise, it may
damage the tool.
Stand on a stable surface, and hold the tool away from
the branches so that the angle of the tool becomes 60°
or less against the horizontal ground.
► Fig.17: 1. 60° or less
Start the tool, and then press the saw chain onto the branch lightly.
When cutting long branches, in order to control the drop position
of cut branches, divide the branch in sections and cut the branch
from the tip. Pay attention to the falling branches since they may
bounce in the direction of the operator after hitting the ground.
► Fig.18
When cutting thick branches, first make a shallow
undercut and then make the finish cut from the top.
► Fig.19
If you try to cut off thick branches from the bottom, the
branch may close in and pinch the saw chain in the cut.
If you try to cut off thick branches from the top without a
shallow undercut, the branch may splinter.
► Fig.20

Carrying tool

Before carrying the tool, always remove the battery cartridge
or the spark plug cap, and then attach the guide bar cover.
Also cover the battery cartridge with the battery cover.

MAINTENANCE
CAUTION:
Always be sure that the motor is
switched off and the battery cartridge or the spark
plug cap is removed before attempting to perform
inspection or maintenance.
CAUTION:
Always wear gloves when perform-
ing any inspection or maintenance.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
To maintain product SAFETY and RELIABILITY,
repairs, any other maintenance or adjustment should
be performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.

Sharpening the saw chain

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.
(caused by uneven sharpening of the saw chain or
damage to one side only)
Sharpen the saw chain frequently but a little 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 our
authorized service center.
Sharpening criteria:
WARNING:
the cutting edge and depth gauge increases the
risk of kickback.
► Fig.22: 1. Cutter length 2. Distance between cutting
edge and depth gauge 3. Minimum cutter
length (3 mm)
— All cutter length must be equal. Different cutter
lengths prevent the saw chain from running
smoothly and may cause the saw chain to break.
— Do not sharpen the chain when the cutter length
has reached 3 mm or shorter. The chain must be
replaced with new one.
— The chip thickness is determined by the distance between
the depth gauge (round nose) and the cutting edge.
— The best cutting results are obtained with following
distance between cutting edge and depth gauge.
• Chain blade 90PX : 0.65 mm
• Chain blade 91PX : 0.65 mm
