○ Be absolutely sure to remove the cut material from the

top of the turntable, and then proceed to the next step.

○ Continued cutting operation can result in overload of the

motor. Touch the motor and if it's hot, stop your cutting

operation once and rest for 10 minutes or so, and then

restart your cutting operation.

9. Cutting narrow workpieces (Press cutting) (Fig. 19)

Slide the hinge down to holder (A), then tighten the

slide securing knob (Fig. 2). Lower the handle to cut

the workpiece. Using the power tool this way will permit

cutting of workpieces of up to 107 mm square.

10. Cutting large workpieces (Fig. 20, 21)

There may be case when a complete cutting cannot be

done depending on the height of workpiece. In this case,

mount an auxiliary board with the 6 mm ﬂ at head screws

and the 6 mm nuts using the 7 mm holes on the fence

surface (two holes on each side). (Fig. 20)

Refer to “SPECIFICATIONS” for the thickness of the

auxiliary board.

NOTE

When cutting a workpiece exceeding 107 mm in height

in right-angle cutting or 70 mm in left bevel angle cutting

or 45 mm in right bevel angle cutting, adjust the lower

limit position so that the base of the motor head will not

come in contact with the workpiece.

To adjust the lower limit position of the saw blade, follow the

procedure (1) shown in Fig. 21.

(1) Lower the motor head, and turn the 8 mm depth

adjustment bolt and make adjustments so that there can

be a clearance of 2 mm to 3 mm between the lower limit

position of the motor head and the top of the workpiece

at the saw blade's lower limit position where the head of

the 8 mm depth adjustment bolt contacts the hinge.

11. Cutting wide workpieces (Slide cutting) (Fig. 22)

(1) Workpieces up to 107 mm high and 312 mm wide:

Loosen the slide securing knob (A) (Fig. 2), grip the

handle and slide the saw blade forward.

Then press down on the handle and slide the saw blade

back to cut the workpiece. This facilitates cutting of

workpieces of up to 107 mm in height and 312 mm in

width.

(2) Workpieces up to 120 mm high and 260 mm wide:

Workpieces of up to 120 mm in height and up to 260 mm

in width can be cut in the same manner as described in

paragraph 15-(1) above.

CAUTION

○ When cutting a workpiece of 120 mm height, adjust

the lower limit position of the motor head so that the

gap between the lower edge of the motor head and the

workpiece will be 2 to 3 mm at the lower limit position.

○ If the handle is pressed down with excessive or lateral

force, the saw blade may vibrate during the cutting

operation and cause unwanted cutting marks on the

workpiece, thus reducing the quality of the cut.

Accordingly, press the handle down gently and carefully.

○ In slide cutting, gently push the handle back (rearwards)

in a single, smooth operation. Stopping the handle

movement during the cut will cause unwanted cutting

marks on the workpiece.

WARNING

○ For slide cutting, follow the procedures.

Forward slide cutting (toward the operator) is very

dangerous because the saw blade could kick upward

from the workpiece. Therefore, always slide the handle

away from the operator.

○ Always return the carriage to the full rear position after

each crosscut operation in order to reduce the risk of

injury.

○ Never put your hand on the side handle during the

cutting operation because the saw blade comes close to

the side handle when the motor head is lowered.

12. Miter cutting procedures

(1) Loosen the side handle and pull up the lever for angle

stoppers. Then, adjust the turntable until the indicator

aligns with desired setting on the miter scale (Fig. 23).

(2) Re-tighten the side handle to secure the turntable in the

desired position.

(3) The miter scale indicates both the cutting angle on the

angle scale and the gradient on the grade scale.

(4) The gradient, which is the ratio of the height to the base

of the triangular section to be removed, may be used

for setting the miter scale instead of the cutting angle, if

desired.

Therefore, to cut a workpiece at a grade of 2/10, set the

indicator to position.

NOTE

○ Positive stops are provided at the right and left of the 0°

center setting, at 15°, 22.5°, 30° and 45° settings.

Check that the miter scale and the tip of the indicator are

properly aligned.

○ Operation of the saw with the miter scale and indicator

out of alignment, or with the side handle not properly

tightened, will result in poor cutting precision.

13. Bevel cutting procedures (Fig. 24)

(1) Loosen the clamp lever and bevel the saw blade to the

left or to the right. When tilting the motor head to the right

pull the set pin (A) towards the rear.

The clamp lever adopts a latchet system. When

contacting the work bench and the main body, pull

the clamp lever in the direction of the arrow mark as

illustrated in Fig. 24, and change the direction of the

clamp lever.

(2) Adjust the bevel angle to the desired setting while

watching the bevel angle scale and indicator, then

secure the clamp lever.

WARNING

When the workpiece is secured on the left or right side

of the blade, the short cut-oﬀ portion will come to rest

on the right or left side of the saw blade. Always turn the

power oﬀ and let the saw blade stop completely before

raising the handle from the workpiece.

If the handle is raised while the saw blade is still rotating,

the cut-oﬀ piece may become jammed against the saw

blade causing fragments to scatter about dangerously.

When stopping the bevel cutting operation halfway, start

cutting after pulling back the motor head to the initial

position.

Starting from halfway, without pulling back, causes the

lower guard to be caught in the cutting groove of the

workpiece and to contact the saw blade.

CAUTION

When cutting a workpiece of 75 mm height in the left 45°

bevel cutting position or a workpiece of 50 mm height in

the right 45° bevel cutting position, adjust the lower limit

position of the motor head so that the gap between the

lower edge of the motor head and the workpiece will be 2

to 3 mm at the lower limit position (refer to “11. Checking

the saw blade lower limit position” on page 35).

14. Compound cutting procedures

Compound cutting can be performed by following the

instructions in 12 and 13 above. For maximum dimensions

for compound cutting, refer to “SPECIFICATIONS” table.

CAUTION

Always secure the workpiece with the right or left

hand and cut it by sliding the round portion of the saw

backwards with the left hand.

It is very dangerous to rotate the turntable to the left

during compound cutting because the saw blade may

come into contact with the hand that is securing the

workpiece.

In case of compound cutting (angle + bevel) by left

bevel, slide the sub-fence (B) outward, and engage in

the cutting operation.
