(1)As shown in Fig. 19 the width of the saw blade is the width of the cut. Therefore, slide the workpiece to the

right (viewed from the operator’s position) when length b is desired, or to the left when length a is desired.

(2)Once the saw blade reaches maximum speed, push the handle down carefully until the saw blade approaches the workpiece.

(3)Once the saw blade contacts the workpiece, push the handle down gradually to cut into the workpiece.

(4)After cutting the workpiece to the desired depth, turn the power tool OFF and let the saw blade stop completely before raising the handle from the workpiece to return it to the full retract position.

CAUTION: * Increased pressure on the handle will not increase the cutting speed.

On the contrary, too much pressure may result in overload of the motor and/or decreased cutting efficiency.

WARNING: * Confirm that the trigger switch is turned OFF and the power plug has been removed from the receptacle whenever the tool is not in use.

*Always remove the lock-off button from the handle and store it in a secure place after completing the work.

Slide the hinge down to holder (A), then tighten the slide securing knob as indicated in Fig. 20.

Lower the handle to cut the workpiece.

Using the power tool this way will permit cutting of workpieces of up to 2-15/16" (75mm) square.

NOTE: When cutting a workpiece of over 2-15/16" (75mm) square, adjust the gap between the holder (A) and the hinge to 25/32" (20mm).

Using the power tool this way will permit cutting of workpieces of up to 3-15/16" (100mm).

(1)Workpieces up to 4-7/32" (107mm) high and 12" (305mm) wide: Loosen the slide securing knob, 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 as indicated in Fig. 21. This facilitates cutting of workpieces of up to 4-7/32" (107mm) in height and 12" (305mm) in width.

(2)Workpieces up to 4-23/32" (120mm) high and 10-7/32" (260mm) wide: Workpieces of up to 4-23/32" (120mm) in height and up to 10-7/32" (260mm) in width can be cut in the same manner as described in paragraph 5-(1) above.

Fig. 21

CAUTION: * When cutting a workpiece of 4-23/32" (120mm) 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 5/64" to 1/8" (2 to 3mm) 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.
