Maintaining maximum cutting capacity
(Fig. 16 & 17)
This tool is factory adjusted to provide the max. cutting
capacity for a 216 mm saw blade. When using a saw
blade other than 216 mm saw blade, adjust the lower limit
position of the blade as follows:
First, remove the battery cartridge. Lower the handle
completely. Use the socket wrench to turn the adjusting
bolt until the periphery of the blade extends slightly below
the top surface of the turn base at the point where the
front face of the guide fence meets the top surface of the
turn base. With the battery cartridge removed, rotate the
blade by hand while holding the handle all the way down
to be sure that the blade does not contact any part of the
lower base. Re-adjust slightly, if necessary.
CAUTION:
After installing a new blade, always be sure that the blade
does not contact any part of the lower base when the
handle is lowered completely. Always do this with the bat-
tery cartridege removed.
Positioning for adjusting the miter angle (Fig. 18)
The turn base turns up to 52° to the left and right. Loosen
the grip by turning counterclockwise. Turn the turn base
while pressing down the lock lever. When you have
moved the grip to the position where the pointer points to
the desired angle on the miter scale, securely tighten the
grip clockwise.
CAUTION:
• When turning the turn base, be sure to raise the handle
fully.
• After changing the miter angle, always secure the turn
base by tightening the grip firmly.
Positioning for adjusting the bevel angle
(Fig. 19 & 20)
The saw blade tilts up to 45° to the left. To adjust the
bevel angle, loosen the lever at the rear of the tool. Push
the handle to the left to tilt the saw blade until the pointer
points to the desired angle on the bevel scale. Tighten
the lever to secure the arm.
CAUTION:
• When tilting the saw blade, be sure to raise the handle
fully.
• After changing the bevel angle, always secure the arm
by tightening the lever.
Securing workpiece
WARNING:
It is extremely important to always secure the workpiece
properly and tightly with the vise. Failure to do so can
cause the tool to be damaged and/or the workpiece to be
destroyed. PERSONAL INJURY MAY ALSO RESULT.
Also, after a cutting operation, DO NOT raise the blade
until the blade has come to a complete stop.
1. Vertical vise (Fig. 21)
The vertical vise can be installed in two positions on
either the left or right side of the guide fence, or the
holder assembly (optional accessory). Insert the
vise rod into the hole in the guide fence or the holder
assembly and tighten the screw to secure the vise
rod. (Note: When using the holder assembly, install it
on the holder as shown in Fig. 21.)
Position the vise arm according to the thickness and
shape of the workpiece and secure the vise arm by
tightening the screw.
Make sure that no part of the tool contacts the vise
when lowering the handle fully. If some part contacts
the vise, re-position the vise. Press the workpiece
flat against the guide fence and the turn base. Posi-
tion the workpiece at the desired cutting position and
secure it firmly by tightening the vise knob. The max-
imum thickness of workpieces which can be secured
by the vertical vise is 61 mm.
2. Horizontal vise (optional accessory)
(Fig. 22 & 23)
The horizontal vise can be installed on either the left
or right side of the base. By turning the vise knob
counterclocwise, the screw is released and the vise
shaft can be moved rapidly in and out. To grip work-
pieces, turn the vise knob gently clockwise until the
projection reaches its topmost position, then fasten
securely. If the vise knob is forced in or pulled out
while being turned clockwise, the projection may
stop at an angle. In this case, turn the vise knob
back counterclockwise until the screw is released,
before turning again gently clockwise. The maximum
width of workpieces which can be secured by the
horizontal vise is 122 mm.
3. Holders and holder assembly (optional accessory)
The holders and the holder assembly can be
installed on either side as a convenient means of
supporting workpieces horizontally. Install them as
shown in Fig. 24. Then tighten the screws firmly to
secure the holders and the holder assembly.
(Fig. 24)
When cutting long workpieces, use the holder-rod
assembly (optional accessory). It consists of two
holder assemblies and two rods 12. (Fig. 25)
CAUTION:
Always support long workpieces level with the top
surface of the turn base for accurate cuts and to pre-
vent dangerous loss of control of the tool.
