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-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 plate and guide plate
Fig.4
Fig.5
The original spacing or interval between the vise plate
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
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 right 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.

Fig.9
To remove the wheel, loosen the clamping screw, hold
the safety guide by both hands and raise it, then slide
the safety guide towards yourself.
Fig.10
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.11
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.
