Always lower the wheel guard after replacing the
wheel.
Securing workpiece
Fig.12
By turning the vise handle counterclockwise and then
flipping the vise nut to the back, 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 front and then turn the vise handle clockwise to
securely retain the workpiece.
CAUTION:
•
Always set the vise nut to the front 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 a dangerous breakage of the wheel.
When the cut-off wheel has worn down considerably,
use a spacer block of sturdy, non-flammable material
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.
Fig.13
When cutting workpieces over 85 mm wide at an angle,
attach a straight piece of wood (spacer) to the guide
plate as shown in the figure. Attach this spacer with
screws through the holes in the guide plate.
Fig.14
If you use a spacer block which is slightly narrower than
the workpiece as shown in the figure, you can also
utilize the wheel economically when worn down the
wheel.
Fig.15
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
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.
CAUTION:
•
Proper handle pressure during cutting and
maximum cutting efficiency can be determined by
the amount of sparks that is produced while
cutting. Your pressure on the handle should be
adjusted to produce the maximum amount of
sparks. 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.

Fold down the tool head to the position where you can
attach the chain to the hook on the handle.
MAINTENANCE
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection
or maintenance.
•
Never use gasoline, benzine, thinner, alcohol or
the like. Discoloration, deformation or cracks may
result.
The tool and its air vents have to be kept clean.
Regularly clean the tool's air vents or whenever the
vents start to become obstructed.
