Operation - Makita LC1230 Betriebsanleitung

Installing or removing saw blade
CAUTION:
• When mounting the blade, make sure that the direction
of the arrow on the surface of the blade matches the
direction of the arrow on the blade case.
• 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.
• Do not touch the blade immediately after operation; it
may be extremely hot and could burn your skin.
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. 8)
Press the shaft lock to lock the spindle and use the
socket wrench to loosen the hex bolt by turning counter-
clockwise. Then remove the hex bolt, outer flange and
blade. (Fig. 9)
To install the blade, mount the inner flange, saw blade,
outer flange and hex bolt onto the spindle in that order.
Tighten the hex bolt by turning clockwise while pressing
the shaft lock. Return the blade guard and center cover
to its original position. Then tighten the hex bolt clock-
wise to secure the center cover. Lower the handle to
make sure that the blade guard moves properly. (Fig. 10)

OPERATION

Cutting operation
CAUTION:
• Never attempt to cut workpieces less than 2 mm thick except pipe or workpieces which cannot be secured firmly with
the vise. The piece cut off may be caught by the blade, causing dangerous scattering of chips and/or damage to the
carbide-tips. Possible serious injury may result.
• Do not apply excessive pressure on the handle when cutting. Too much pressure may result in overload of the motor,
decreased cutting efficiency and/or damage to the carbide-tips or blade itself.
• Too little pressure on the handle may result in more sparks and premature blade wear.
• Do not touch the blade, workpiece or cutting chips immediately after operation; they may be extremely hot and could
burn your skin.
• If the blade stops during operation, makes an odd noise or begins to vibrate, switch off the tool immediately. Replace
cracked or damaged blade with a new one.
• Do not cut aluminum, wood, plastics, concrete, tiles, etc.
• Always use carbide-tipped saw blades appropriate for your job. The use of inappropriate saw blades may cause a
poor cutting performance and/or present a risk of personal injury.

Securing workpieces
CAUTION:
• Always set the vise nut to the right fully when securing
the workpiece. Failure to do so may result in insufficient
securing of the workpiece. This could cause the work-
piece to be ejected or cause damage to the blade.
By turning the vise handle counterclockwise and then
flipping the vise nut to the left, the vise is released from
the shaft threads and can be moved rapidly in and out. To
grip workpieces, push the vise handle until the vise plate
contacts the workpiece. Flip the vise nut to the right and
then turn the vise handle clockwise to securely retain the
workpiece. (Fig. 11)
Long workpieces must be supported by blocks of non-
flammable material on either side so that it will be level
with the base top. (Fig. 12)
