16. Installing the holders ... (Optional accessory)
The holders help keep longer workpieces stable and in
place during the cutting operation.
(1) As indicated in Fig. 25, use a steel square for aligning
the upper edge of the holders with the base surface.
Loosen the 6 mm wing nut. Turn a height adjustment bolt
6 mm, and adjust the height of the holder.
(2) After adjustment, fi rmly tighten the 6 mm wing nut and
fasten the holder with the 6 mm knob bolt (optional
accessory). If the length of Height Adjustment Bolt 6 mm
is insuffi cient, spread a thin plate beneath. Make sure the
end of Height Adjustment Bolt 6 mm does not protrude
from the holder.
CAUTION
○ When transporting or carrying the tool, do not grasp the
holder.
○ There is the danger of the holder slipping out of the base.
Grasp the handle instead of the holder.
17. Stopper for precision cutting ... (Stopper and
holder are optional accessory)
The stopper facilitates continuous precision cutting in
lengths of 285 mm to 450 mm.
To install the stopper, attach it to the holder with the
6 mm knob bolt as shown in Fig. 26.
18. Confi rmation for use Crown molding vise, Crown
molding Stopper (L) and (R) (Optional accessory)
(1) Crown molding Stopper
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. 27. 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, fi rst loosen the hex. socket set screw.
After adjusting the height, fi rmly tighten the 6 mm wing
bolt; then turn the upper knob, as necessary, to securely
attach the the crown molding in position (Fig. 28).
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. 28. 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
fi rmly (Fig. 11).
WARNING
Always fi rmly 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 confi rm that the motor head 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 hex.
socket set screw and move the crown molding vise ass'y
to a position where it will not contact the saw blade.
19. Groove cutting procedures
Grooves in the workpiece can be cut by adjusting the 6
mm depth adjustment bolt (Fig. 29).
(1) Turn the stopper holder on the direction shown in
Fig. 30.
(L) and (R) (optional
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. 29).
NOTE
When cutting a single groove at either end of the
workpiece, remove the unneeded portion with a chisel.
20. Using the dust bag (Standard accessory) (Fig. 31)
(1) Connect the dust bag with the duct of power tool.
(2) When the dust bag has become full of sawdust, dust will
be blown out of the dust bag when the saw blade rotates.
Check the dust bag periodically and empty it before it
becomes full.
(3) During bevel and compound cutting, attach the dust bag
at the right angle to the base surface.
21. Connecting the dust extractor (Sold separately)
(Fig. 32)
Do not inhale the harmful dusts generated in cutting
operation.
The dust can endanger the health of yourself and
bystanders.
Use of dust extractor can reduce dust related hazards.
By connecting with dust extractor through adapter,
joint and dust collection adapter, most of dust can be
collected.
Connect the dust extractor with adapter.
(1) Connect in order of hose (id 38 mm × 3 m long) and
adapter (Dust extractor's Standard accessory) joint
(Optional accessory) and dust collection adapter
(Optional accessory) with the duct of power tool.
Connection is done by pressing in the direction of the
arrow. (Fig. 32)
The dust collection adapter (Optional accessory) is fi xed
