Return the safety cover and center cover to its original
position. Then tighten the hex bolt clockwise to secure
the center cover. (Fig. 11)
Release the handle from the raised position by pulling
the stopper pin. Lower the handle to make sure that the
safety cover moves properly.
Safety cover (Fig. 12)
When lowering the handle, the safety cover rises auto-
matically. The cover returns to its original position when
the cut is completed and the handle is raised. NEVER
DEFEAT OR REMOVE THE SAFETY COVER. In the
interest of your personal safety, always maintain the
safety cover in good condition. Any irregular operation of
the safety cover should be corrected immediately.
NEVER USE THE TOOL WITH A FAULTY SAFETY
COVER. If the see-through safety cover becomes dirty,
or sawdust adheres to it in such a way that the blade and/
or workpiece is no longer easily visible, remove the bat-
tery cartridge and clean the cover carefully with a damp
cloth. Do not use solvents or any petroleum-based clean-
ers on the plastic cover.
Dust bag (Fig. 13)
The use of the dust bag makes cutting operations clean
and dust collection easy. To attach the dust bag, fit the
bag ’ s entry port over the dust nozzle. When the dust bag
is about half full, remove the dust bag from the tool and
pull the fastener out. Empty the dust bag of its contents,
tapping it lightly so as to remove particles adhering to the
insides which might hamper further collection.
Positioning kerf board (Fig. 14 & 15)
This tool is provided with the kerf boards in the turn base.
The kerf boards are factory adjusted so that the saw
blade does not contact the kerf boards. Before use,
adjust the kerf boards as follows:
First, remove the battery cartridge. Loosen the all screws
(2 each on left and right) securing the kerf boards. Re-
tighten them to the extent that the kerf boards can be
easily moved by hand. Lower the handle fully and push in
the stopper pin to lock the handle in the lowered position.
Adjust the kerf boards so that the kerf boards just contact
the sides of blade teeth slightly. Tighten the screws (do
not tighten firmly). After adjusting the kerf boards,
release the stopper pin and raise the handle. Then
tighten the all screws securely.
CAUTION:
After changing the bevel angle, always readjust the kerf
boards as described above.
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.

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.
