Carefully instruct the customer never, ever to perform slide cutting in the direction toward the
operator. Such operation is extremely hazardous, as the saw blade could ride up over the
workpiece and cause the saw blade section (head) to kick upward unexpectedly, causing possible
serious injury (see arrow
Instruct the customer to always slide the saw blade section toward the fence while cutting, as
shown by arrow
On completion of the cutting operation, turn the switch OFF and wait for the saw blade to come to a
5
complete stop before raising the saw blade section (head) to its original position. Raising the saw blade
section while the saw blade is rotating may cause unwanted cutting marks on the workpiece.
Techniques to avoid unwanted cutting marks
Uneven and unwanted cutting marks can be avoided throughout the cutting operation by gently and
smoothly pressing down on the handle (arrow
Fig. 35) uniformly, so that the entire cutting operation is accomplished in a single, uninterrupted motion.
Advise the customer that he or she will quickly develop a "feel" and skill for smooth cutting after performing
two or three practice cutting operations.
(5) Miter cutting
Miter cutting is accomplished by turning the turn table. (For details, please refer to the Handling Instructions.)
(6) Bevel cutting
Bevel cutting of 0 --- 45˚ to the left or right is accomplished by inclining the saw blade section (head).
(For details, please refer to the Handling Instructions.)
[CAUTION] If bevel cutting is interrupted before cutting completely through the workpiece, the saw
blade must be lifted to the initial cutting position without fail. If bevel cutting is restarted at the point
where it was interrupted, the safety cover, which enters the cutting groove, may come in contact with
and damage the saw blade, which could be very dangerous. Also, when bevel cutting a workpiece
75 mm (2-15/16") in height with the saw blade tilted 45˚ to the left, or when bevel cutting a workpiece
45 mm (1-25/32") in height with the saw blade tilted 45˚ to the right, adjust the saw so that there is a
clearance of 2 to 3 mm (0.079" to 0.118") between the lower surface of the saw blade tip and the upper
surface of the workpiece. (Please refer to paragraph 8-2, Confirmation of Saw Blade Lower Limit
Positioning.)
(7) Compound (Miter + Bevel) cutting
Compound cutting can be accomplished by combining the miter cutting and bevel cutting operations described
in paragraphs (5) and (6), above. (For details, please refer to the Handling Instructions.)
When the saw blade section (head) is inclined 45˚ to the left, the turn table can be turned up to 45˚ to the left
and right. When the saw blade section (head) is inclined 45˚ to the right, the turn table can be turned up to 31˚
to the left, and up to 45˚ to the right.
