CAUTION:
• Be sure to tighten the hex bolt securely. Insufficient
tightening of the hex bolt may result in severe injury.
Use the socket wrench provided to help assure proper
tightening.
• Always use only the proper inner and outer flanges
which are provided with this tool.
• Always lower the safety guide after replacing the wheel.
Spark guard (Fig. 3)
The spark guard is factory-installed with its lower edge
contacting the base. Operating the tool in this position
will cause many sparks to fly around. Loosen the screw
and adjust the spark guard to a position at which mini-
mum sparks will fly around.
Interval between vise and guide plate (Fig. 4 & 5)
The original spacing or interval between the vise and the
guide plate is 0 – 170 mm. If your work requires wider
spacing or interval, proceed as follows to change the
spacing or interval.
Remove the two hex bolts which secure the guide plate.
Move the guide plate as shown in Fig. 5 and secure it
using the hex bolts. The following interval settings are
possible:
35 – 205 mm
70 – 240 mm
CAUTION:
Remember that narrow workpieces may not be secured
safely when using the two, wider interval settings.
Setting for desired cutting angle (Fig. 6)
To change the cutting angle, loosen the two hex bolts
which secure the guide plate. Move the guide plate to the
desired angle (0° – 45°) and tighten the hex bolts securely.
CAUTION:
Never perform right miter cuts when the guide plate is set
at the 35 – 205 mm or 70 – 240 mm position.
Securing workpieces
By turning the vise handle counterclockwise and then
flipping the vise nut to the left, 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 right and
then turn the vise handle clockwise to securely retain the
workpiece. (Fig. 7)
CAUTION:
Always set the vise nut to the right fully when securing
the workpiece. Failure to do so may result in insufficient
securing of the workpiece. This could cause the work-
piece 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 Fig. 8. You can more effi-
ciently utilize the worn wheel by using the mid point on
the periphery of the wheel to cut the workpiece.
When cutting workpieces over 65 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 Fig. 9.
Attach this spacer with screws through the holes in the
guide plate.
If you use a spacer block which is slightly narrower than
the workpiece as shown in Fig. 10, you can also utilize
the wheel economically.
Long workpieces must be supported by blocks of non-
flammable material on either side so that it will be level
with the base top. (Fig. 11)
Switch action
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the "OFF"
position when released.
For tool with lock button (Fig. 12)
To start the tool, simply pull the trigger. Release the trig-
ger to stop. For continuous operation, pull the trigger and
then push in the lock button. To stop the tool from the
locked position, pull the trigger fully, then release it.
For tool with lock-off button (Fig. 12)
To prevent the trigger from being accidentally pulled, a
lock-off button is provided. To start the tool, press the
lock-off button and pull the trigger. Release the trigger to
stop.
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, gradu-
ally 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 cut-
ting 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 exces-
sive 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.
