Cutting Capacity - Makita LW1400 Manuel D'instructions

Removing or installing cut-off wheel
CAUTION:
Be sure to tighten the toolless
clamp or hex bolt securely. Insufficient tightening
may result in severe injury. When tightening the hex
bolt, use the socket wrench provided with the tool to
assure proper tightening.
CAUTION:
Always use only the proper inner
and outer flanges which are provided with the
tool.
CAUTION:
Always lower the safety guard
after replacing the wheel.
CAUTION:
Wear gloves when handling
wheels.

For LW1400
Raise the safety guard. Turn the toolless clamp coun-
terclockwise while holding down the shaft lock. Then
remove the toolless clamp, outer flange and cut-off
wheel. When removing the cut-off wheel, do not remove
the inner flange as well as the ring and O-ring.

To install the cut-off wheel, follow the removal proce-
dures in reverse. Make sure to fit the hole of cut-off
wheel to the ring and return the safety guard.
For LW1401
Raise the safety guard. Turn the hex bolt counterclock-
wise using a socket wrench while holding down the
shaft lock. Then remove the hex bolt, outer flange and
wheel.

To install the wheel, follow the removal procedures in
reverse. Make sure to fit the hole of cut-off wheel to the
ring and return the safety guard.
OPERATION
CAUTION:
Proper handle pressure during
cutting and maximum cutting efficiency can
be determined by the amount of sparks that is
produced while cutting. Do not force the cut
by applying excessive pressure on the handle.
Reduced cutting efficiency, premature wheel wear, as
well as, possible damage to the tool, cut-off wheel or
workpiece may result.
Hold the handle firmly. Switch on the tool and wait until
the wheel attains full speed before lowering gently
into the cut. When the wheel contacts the workpiece,
gradually bear down on the handle to perform the cut.
When the cut is completed, switch off the tool and wait
until the wheel has come to a complete stop before
returning the handle to the fully elevated position.

Cutting capacity

Maximum cutting capacity varies depending on the
cutting angle and workpiece shape.

Securing workpiece
CAUTION:
Always place the thread holder on
the shaft threads 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 a dangerous breakage of the wheel.
While the thread holder is lifted, the vise plate can be
moved in and out quickly. To grip a workpiece, push the
handle until the vise plate contacts the workpiece then
return the thread holder. Turn the handle clockwise until
the workpiece is securely retained.

When the cut-off wheel has worn down considerably, place
a spacer block behind the workpiece as shown in the figure.
You can more efficiently utilize the worn wheel by using the
mid point on the periphery of the wheel to cut the workpiece.
Use a sturdy and non-flammable material for a spacer block.
► Fig.19: 1. Spacer block
When cutting workpieces over 85 mm wide at an angle,
attach a straight piece of wood (spacer) over 190 mm
long x 45 mm wide to the guide plate as shown in the
figure. Attach this spacer with screws through the holes
in the guide plate. Make sure that the cut-off wheel does
not contact the spacer when the tool head is depressed.

mm long x45 mm wide) 3. Workpiece (over

► Fig.21
When the cut-off wheel has worn down, raise the cutting
position by putting a spacer block which is slightly nar-
rower than the workpiece as shown in the figure. This
will help you to utilize the wheel economically.
