13. Remove material or debris from the area that
might be ignited by sparks. Be sure that others
are not in the path of the sparks. Keep a proper,
charged fire extinguisher closely available.
14. Use the cutting edge of the wheel only. Never
use side surface.
15. If the wheel stops during the operation, makes
an odd noise or begins to vibrate, switch off the
tool immediately.
16. Always switch off and wait for the wheel to come
to a complete stop before removing, securing
workpiece, working vise, changing work posi-
tion, angle or the wheel itself.
17. Do not touch the workpiece immediately after
operation; it is extremely hot and could burn
your skin.
18. Store wheels in a dry location only.
SAVE THESE INSTRUCTIONS.
OPERATING INSTRUCTIONS
Removing or installing cut-off wheel
Important:
Always be sure that the tool is switched off and
unplugged before removing or installing the wheel.
1. To remove the wheel, raise the safety guide. Press
the shaft lock so that the wheel cannot revolve and
use the socket wrench to loosen the hex bolt by turn-
ing it counterclockwise. (Fig. 1)
2. Then remove the hex bolt, outer flange and wheel.
(Fig. 2)
Note: Do not remove the inner flange, ring and
O-ring.
3. To install the wheel, follow the removal procedures in
reverse.
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. Before operation, loosen the screw
and raise the spark guard so that its lower edge will be
positioned approx. 45 mm above the workbench or floor
surface.
Otherwise sparks may fly around operation area.
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:
35–205mm
70–240mm
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 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)
