If the battery is reinserted within 3 seconds, the battery may not be properly charged.

PRIOR TO OPERATION

1.Setting up and checking the work environment Check if the work environment is suitable by following the precautions.

2.Prepare a wooden workbench (Fig. 11)

Since the saw blade will extend beyond the lower surface of the lumber, place the lumber on a workbench when cutting. If a square block is utilized as a workbench, select level ground to ensure it

is properly stabilized. An unstable workbench will result in hazardous operation.

CAUTION

To avoid possible accident, always ensure that the portion of lumber remaining after cutting is securely anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE

CAUTION

Pull out battery before doing any adjusting.

1.Adjusting the cutting depth

As shown in Fig. 12, hold the handle with one hand while loosening the knob with the other.

The cutting depth can be adjusted by moving the base to the desired position. In such manner adjust the cutting depth and then securely retighten the knob.

2.Adjusting the riving knife

Loosen the hexagonal – head bolt used to clamp the riving knife, adjust the riving knife to the position shown in Fig. 13 and securely retighten the bolt.

3.Adjusting the angle of inclination

As shown in Fig. 14 (A), Fig. 14 (B) by loosening the knob on the incline gauge and the wing-bolt on the base, the saw blade may be inclined to a maximum angle of 45° in relation to the base. After having completed the adjustment, reconfirm that

the knob and the wing bolt are firmly tightened.

NOTE:

Values of the inclined gauge provided on the base merely serve as a rough guideline. For cutting operation at an inclined posture, use the circular saw after adjusting the angle between the base and the saw blade with a protractor, etc.

4.Adjusting the guide piece

On the circular saw, it is possible to make fine adjustment of the fixing position of the guide piece, where the saw blade and the premarked line are to be aligned.

When the saw is shipped from the factory, the linear portion of a front scale on the guide piece is aligned with the central position of the saw blade. (Fig. 15)

Loosen the fixed screw on the guide piece, should the fixing position be wrong, and make necessary

adjustment of the position.

NOTE:

For cutting operation at the inclination of 45 degrees, make adjustment so that the notch on the guide piece and the premarked line become aligned.

5.Regulating the guide (Fig. 16)

The cutting position can be regulated by moving the guide to the left or right after loosening its wingbolt. The guide may be mounted on either the right or left side of the tool.

HOW TO USE

1.Operation of switch (Fig. 17) (switch trigger and light switch)

(1)For safe operation of the machine, a “switch lock” is provided on the side of a handle.

If the “switch trigger” is pulled in a state where “switch lock” is pressed in the direction of the arrow mark, the main switch can be turned ON. And the “switch lock” is used as the “light switch”. If the “switch lock (light switch)” is pressed in a state, the light is turned ON.

(2)After the switch is turned ON, even when you release your hand from the switch lock, the body continues running and the light continues being turned ON as long as you keep on pulling the switch trigger.

(3)If you release the switch trigger, you can turn OFF the switch and the “switch lock” returns to the

original position automatically and the light turns OFF too.

CAUTION:

Do not fix and secure the switch lock. Besides, keep your finger off the switch trigger when the circular saw is being carried around. Otherwise, the main body switch can be inadvertently turned ON, resulting in unexpected accidents.

Keep the light ON during cutting operation only. If it is lit ON in other cases, the main body switch can be inadvertently turned ON, resulting in unexpected accidents.

If the main body is left as it is with the battery inserted, there can be a case where the [switch lock] touches the floor and/or wall surface and lights up continuously, depending on the direction of the body. Be careful, since continuous lighting can easily make a full-charged battery go dead in about 3

hours.”

2.Cutting procedures

CAUTION:

Recheck that the saw blade is securely clamped. Confirm that the knob for adjusting the slot depth, the knob and the wing bolt for adjusting the angle

of inclination.

(1) Place the base on the material, then align the premarked line and the sawblade with the guide piece front scale section at the front of the base. (Fig. 15)

When the base is not slanted, use the large cutout as the guide. (Fig. 15, Fig. 18(A))

If the base is slanted (45 degrees), use the small front scale as the guide. (Fig. 15, Fig. 18(B))

(2) Ensure that the switch is turned to the ON position before the saw blade comes in contact with the lumber. The switch is turned ON when the trigger is squeezed; and OFF when the trigger is released. Moving the saw straight at a constant speed will produce optimum cutting.
