Securing Workpiece; Cutting Operation - Makita LC1230 Instruction Manual

to secure the center cover. Lower the handle to make sure
that the blade guard moves properly. (Fig. 10)

Securing workpiece

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
workpiece 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)

Hold the handle firmly. Switch on the tool and wait until
the blade attains full speed. Then lower the handle gently
to bring the blade close to the workpiece. When the blade
makes contact, ease into the cut gently at first, then
gradually add pressure as the cutting position steadies.
Your pressure on the handle should be adjusted to
produce the minimum amount of sparks.
When the cut is completed, switch off the tool and WAIT
UNTIL THE BLADE HAS COME TO A COMPLETE STOP
before returning the handle to the fully elevated position. If
the handle is raised while the blade is still rotating, the
piece cut off may be caught by the blade, causing
dangerous scattering of chips. When cutting only part of
the way into a workpiece, raise the handle while the blade
is rotating. Switching off during the cut may cause
damage to the carbide-tips as they contact the workpiece.

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.

Secure the workpiece in the vise as shown in the Figure A
and proceed to cut it. The saw blade life will be shortened
if the workpiece is cut as shown in the Fig B.
CAUTION:
• Do NOT cut the workpiece as shown in the Fig. C since
this may cause it to be ejected from the vise, possibly
resulting in injury.
The saw blade is subjected to greater wear when the area
A in the Fig. B is cut. Place a wooden block up against the
workpiece as shown in the Fig. D so that the saw blade
will enter area A at an angle. This will help to extend the
saw blade life.
The allowable cutting dimensions are reduced when a
wooden block is used. Use a wooden block whose
dimensions are equivalent to the maximum allowable
cutting dimensions minus the dimensions of the
