To install the stopper, attach it to the holder with the
6 mm knob bolt as shown in Fig. 28.
24. Confirmation for use Crown molding vise, Crown
molding Stopper (L) and (R) (Optional accessory)
(1) Crown molding Stopper (L) and (R) (optional
accessories) allow easier cuts of crown molding
without tilting the saw blade. lnstall them in the base
both-sides side to be shown in Fig. 29. After inserting
tighten the 6 mm knob bolts to secure the Crown
molding Stoppers.
(2) The crown molding vise (B) (Optional accessory) can
be mounted on either the left fence (Fence (B)) or the
right fence (Fence (A)). lt can unite with the slope of
the crown molding and vice can be pressed down.
Then turn the upper knob, as necessary, to securely
attach the crown molding in position. To raise or lower
the vise assembly, first loosen the 6 mm knob bolt.
After adjusting the height, firmly tighten the 6 mm wing
bolt; then turn the upper knob, as necessary, to securely
attach the the crown molding in position (Fig 30).
Position crown molding with its WALL CONTACT EDGE
against the guide fence and its CEILING CONTACT
EDGE against the Crown molding Stoppers as shown
in Fig. 30. Adjust the Crown molding Stoppers
according to the size of the crown molding.
Tighten the 6 mm wing bolt to secure the Crown
molding Stoppers. Refer to the lower table for the miter
angle.
Use the sub fence (A) to secure the crown molding
more firmly (Fig. 11).
WARNING
Always firmly clamp or vise to secure the crown
molding to the fence; otherwise the crown molding
might be thrust from the table and cause bodily harm.
Do not bevel cutting. The main body or saw blade
may contact the sub fence, resulting in an injury.
CAUTION
Always confirm that the motor head (Fig. 1) does not
contact the crown molding vise ass'y when it is
lowered for cutting. If there is any danger that it may
do so, loosen the 6mm knob bolt and move the crown
molding vise ass'y to a position where it will not
contact the saw blade.
25. Groove cutting procedures
Grooves in the workpiece can be cut by adjusting the
6 mm depth adjustment bolt (Fig. 32).
(1) Turn the stopper holder on the direction shown in Fig.
32.
Lower the motor head, and turn the 6 mm depth
adjustment bolt by hand. (Where the head of the 6
mm depth adjustment bolt contacts the hinge.)
(2) Adjust to the desired cutting depth by setting the
distance between the saw blade and the surface of
the base (Fig. 31).
NOTE
When cutting a single groove at either end of the
workpiece, remove the unneeded portion with a
chisel.
MOUNTING AND DISMOUNTING SAW BLADE
WARNING
To prevent an accident or personal injury, always turn
off the trigger switch and disconnect the power plug
from the receptacle before removing or installing a
saw blade.
21
If cutting work is done in a state where the 10 mm
bolt is not sufficiently tightened, the 10 mm bolt can
get loose, the blade can come off, and the lower guard
can get damaged, resulting in injuries.
Also, check that the 10 mm bolts are properly
tightened before plugging the power plug into the
receptacle.
If the 10 mm bolts are attached or detached using tools
other than the 17 mm box wrench (standard
accessory), excessive or improperly tightening occurs,
resulting in injury.
1. Mounting the saw blade (Fig. 33, Fig. 34, Fig. 35 and
Fig. 36)
(1) Use the Phillips screwdriver to loosen the 5 mm screw
fastening the spindle cover and then turn the spindle
cover.
(2) Press in spindle lock and loosen 10 mm bolt with 17
mm box wrench (standard accessory).
Since the 10 mm bolt is left-hand threaded, loosen by
turning it to the right as shown in Fig. 35.
NOTE
If the spindle lock cannot be easily pressed in to lock
the spindle, turn the 10 mm bolt with 17 mm box
wrench (standard accessory) while applying pressure
on the spindle lock.
The saw blade spindle is locked when the spindle lock
is pressed inward.
(3) Remove the bolt and washer (D)
(4) Lift the lower guard and mount the saw blade.
WARNING
When mounting the saw blade, confirm that the
rotation indicator mark on the saw blade and the
rotation direction of the spindle cover (Fig. 1) are
properly matched.
(5) Thoroughly clean washer (B) and the 10 mm bolt, and
install them onto the saw blade spindle.
(6) Press in the spindle lock and tighten the 10 mm bolt
by turning it to the left by standard accessories (17
mm box wrench) as indicated in Fig. 35.
CAUTION
A dust guide is installed inside behind the hinge.
When removing or installing the saw blade, do not
make contact with the dust guide. Contact may break
or chip saw blade tips.
Confirm that the spindle lock has returned to the
retract position after installing or removing the saw
blade.
Tighten the 10 mm bolt so it does not come loose
during operation.
Confirm the 10 mm bolt has been properly tightened
before the power tool is started.
2. Dismounting the saw blade
Dismount the saw blade by reversing the mounting
procedures described in paragraph 1 above.
The saw blade can easily be removed after lifting the
lower guard.
CAUTION
Never attempt to install saw blades except
290 mm – 305 mm in diameter.
