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.
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 cut-off wheel attains full speed before lowering
gently into the cut. When the cut-off 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 cut-off 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.

NOTE:
A workpiece thinner than 1.6 mm is recom
-
mended for cutting with this tool.
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 cut-off
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-flam
-
mable material for a spacer block.

Spacer block
When cutting workpieces over 85 mm wide at an angle,
attach a straight piece of wood (spacer) over 190 mm
long x 40 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.

NOTICE:
When using a spacer block, install the
guide plate to the position nearest to the neck of
the tool head.

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 cut-off wheel economically.

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