OPERATION
CAUTION: Proper handle pressure during
cutting and maximum cutting efciency 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 efciency, premature wheel wear, as
well as, possible damage to the tool, cut-off wheel or
workpiece may result.
Hold the handle rmly. 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 (1/16″) is
recommended 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 insufcient 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 gure. You can more efciently utilize the worn
wheel by using the mid point on the periphery of the
wheel to cut the workpiece. Use a sturdy and non-am-
mable material for a spacer block.

When cutting workpieces over 85 mm (3-3/8″) wide at
an angle, attach a straight piece of wood (spacer) over
190 mm (7-1/2″) long x 40 mm (1-9/16″) wide to the
guide plate as shown in the gure. 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.
