INSTALLATION

Securing cut-off (Fig. 1)
This tool should be bolted with two bolts to a level and
stable surface using the bolt holes provided in the tool's
base. This will help prevent tipping and possible personal
injury.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Switch action (Fig. 2)
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
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop. For continuous operation, pull
the switch trigger and then push in the lock button. To
stop the tool from the locked position, pull the switch
trigger fully, then release it.
For tool with lock-off button
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, depress the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
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 minimum
sparks will fly around.
Interval between vise and guide plate
(Fig. 4)
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 the figure and secure it
using the hex bolts. The following interval settings are
possible:
35 - 205 mm
70 - 240 mm (Fig. 5)
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, follow the procedure below:
1. Loosen the two hex bolts.
2. Set the guide plate to the desired angle (0° - 45°).
3. For more accurate angle, use a protractor or triangle
ruler. Keep the handle down so that the cut-off wheel
extends into the base. At the same time, adjust the
angle between the guide plate and the cut-off wheel
with a protractor or triangle ruler.
4. Tighten the hex bolts securely. At this time, make sure
that the guide rule does not move.
5. Check the angle again.
CAUTION:
• Never perform miter cuts when the guide plate is set at
the 35 - 205 mm or 70 - 240 mm position.
NOTE:
• The scale on the guide plate is only a rough indication.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Removing or installing cut-off wheel
(Fig. 7)
To remove the wheel, raise the safety guard. Press the
shaft lock so that the wheel cannot revolve and use the
socket wrench to loosen the hex bolt by turning it
counterclockwise. Then remove the hex bolt, outer flange
and wheel. (Note: Do not remove the inner flange, ring
and O-ring.)
To install the wheel, follow the removal procedures in
reverse. (Fig. 8)
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 guard after replacing the
wheel.
Securing workpiece (Fig. 9)
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.
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
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. 10)
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 the figure.
Attach this spacer with screws through the holes in the
guide plate. (Fig. 11)
