Cutting Operation - Makita LC1230 Instruction Manual

Long workpieces must be supported by blocks of
non-flammable material on either side so that it will be
level with the base top.
OPERATION

Cutting operation

CAUTION:
• Never attempt to cut workpieces less than 14
gauge (0.08") 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.
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 posi-
tion 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.
Cutting angles
Secure the workpiece in the vise as shown in the Figure
A and proceed to cut it. The saw blade life will be short-
ened 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 work-
piece to be cut. This will further minimize the shortening
of the saw blade life.
