Makita LS1440 Betriebsanleitung Seite 10

Electric brake
This tool is equipped with an electric blade brake. If the
tool consistently fails to quickly stop blade after switch
trigger release, have tool serviced at a Makita service
center.
The blade brake system is not a substitute for blade
guard. NEVER USE TOOL WITHOUT A FUNCTIONING
BLADE GUARD. SERIOUS PERSONAL INJURY CAN
RESULT.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing saw blade
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing the blade.
• Use only the Makita socket wrench provided to install
or remove the blade. Failure to do so may result in
overtightening or insufficient tightening of the hex bolt.
This could cause a personal injury.
To remove the blade, use the socket wrench to loosen
the hex bolt holding the center cover by turning it coun-
terclockwise. Raise the blade guard and center cover.
(Fig. 10)
Press the shaft lock to lock the spindle and use the
socket wrench to loosen the hex bolt clockwise. Then
remove the hex bolt, outer flange and blade. (Fig. 11 &
12)
To install the blade, mount it carefully onto the spindle,
making sure that the direction of the arrow on the surface
of the blade matches the direction of the arrow on the
blade case. Install the outer flange and hex bolt, and then
use the socket wrench to tighten the hex bolt (left-
handed) securely counterclockwise while pressing the
shaft lock. (Fig. 13 & 14)
CAUTION:
• The inner flange has a 25 mm diameter on one side
and a 25.4 mm diameter on the other. The side with
25.4 mm diameter is marked by "25.4". Use the correct
side for the hole diameter of the blade you intend to
use. Mounting the blade on the wrong side can result in
dangerous vibration.
Slip the pin on the blade guard into the slot in the guide
arm while returning the blade guard to its original fully
closed position. Then tighten the hex bolt clockwise to
secure the center cover. Lower the handle to make sure
that the blade guard moves properly. Make sure shaft
lock has released spindle before making cut. (Fig. 15)
Dust bag
(Fig. 16)
The use of the dust bag makes cutting operations clean
and dust collection easy. To attach the dust bag, fit it onto
the dust nozzle.
When the dust bag is about half full, remove the dust bag
from the tool and pull the fastener out. Empty the dust
bag of its contents, tapping it lightly so as to remove par-
ticles adhering to the insides which might hamper further
collection.

NOTE:
• If you connect a Makita vacuum cleaner to your saw,
more efficient and cleaner operations can be per-
formed.
Securing workpiece
Whenever possible, secure the workpiece with the
optional vise. If you must use your hand to hold the work-
piece, then it must be done firmly and securely so as not
to lose control of the workpiece. Your hand and arm must
be kept well away from the blade area (100 mm mini-
mum). Squeeze the workpiece firmly against the guide
fence with your fingers held over the top of the guide
fence. The workpiece must also rest steadily on the turn
base.
WARNING:
• Never use your hand to hold the workpiece that
requires your hand to be any closer than 100 mm from
the blade area. In this case, always use the optional
vise to secure the workpiece. After any cutting opera-
tion, raise the blade gently. Never raise the blade until it
has come to a complete stop. Serious injury may result.
Horizontal vise (optional accessory) (Fig. 17)
The horizontal vise can be installed on either the left or
right side of the base. When performing 30° or greater
miter cuts, install the horizontal vise on the side opposite
the direction in which the turn table is to be turned. By
turning the vise knob counterclockwise, the screw is
released and the vise shaft can be moved rapidly in and
out. By turning the vise knob clockwise, the screw
remains secured. To grip the workpiece, turn the vise
knob gently clockwise until the projection reaches its top-
most position, then fasten securely. If the vise knob is
forced in or pulled out while being turned clockwise, the
projection may stop at an angle. In this case, turn the
vise knob back counterclockwise until the screw is
released, before turning again gently clockwise.
CAUTION:
• Grip the workpiece only when the projection is at the
topmost position. Failure to do so may result in insuffi-
cient securing of the workpiece. This could cause the
workpiece to be thrown, cause damage to the blade or
cause the loss of control, which can result in PER-
SONAL INJURY.
Holders and holder assembly (optional accessories)
(Fig. 18)
The holders and the holder assembly can be installed on
either side as a convenient means of supporting work-
pieces horizontally. Install them as shown in Fig. 18.
Then tighten the screws firmly to secure the holders and
the holder assembly.
When cutting long workpieces, use the holder-rod
assembly (optional accessory). It consists of two holder
assemblies and two rods 12. (Fig. 19)
CAUTION:
• Always support long workpieces level with the top sur-
face of the turn base for accurate cuts and to prevent
dangerous loss of control of the tool.
