ADJUSTING THE SAW PRIOR TO USE

1.Adjusting the cutting depth

As shown in Fig. 3, 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 angle of inclination

As shown in Fig. 4 (A), Fig. 4 (B) by loosening the wing-nut 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 wing-nut and the wing-bolt are firmly tightened.

3.Regulating the guide (Fig. 5)

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.

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. 6).

Loosen the fixed M4 screw on the guide piece, should the fixing position be wrong, and make necessary adjustment of the position.

CUTTING PROCEDURES

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. 6).

When the base is not slanted, use the large cutout as the guide (Fig. 6, Fig. 7 (A)).

If the base is slanted (45 degrees), use the small front scale as the guide (Fig. 6, Fig. 7 (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.

3.Moving the saw straight at a constant speed will produce optimum cutting.

CAUTIONS

Prior to cutting operation, make sure the material you are going to cut. If the material to be cut is expected to generate harmful / toxic dusts, make sure the dust bag or appropriate dust extraction system is connected with dust outlet tightly.

Wear the dust mask additionally, if available.

A coating of PFTE is applied to the bases of the C9BA2 type. Be careful not to press too hard on the unit body since this tends to place a heavy load on the motor. Using a gentle pressure will make the piece slide easier and allow cutting with less force. Trying to cut wood that is covered with hard particle material such as sand or metal chips tends to easily scratch damage the surface coating so use caution.

￿Before starting to saw, ensure that the saw blade has reached full speed revolution.

￿Should the saw blade be stopped or made an abnormal noise during operation, turn off the switch immediately.

￿Always take care in preventing the power cord from coming near the revolving saw blade.

￿Using the circular saw with the saw blade facing upwards or sideways is very hazardous. Such uncommon applications should be avoided.

￿When cutting materials, always wear protective glasses.

￿When finished with a job, pull out the plug from the receptacle.

MOUNTING AND DISMOUNTING THE SAW BLADE

CAUTION

To avoid serious accident, ensure the switch is in the OFF position, and the power source is disconnected.

1. Dismounting the saw blade

(1)Set the cutting volume at maximum, and place the Circular Saw as shown in Fig. 8.

(2)Depress the lock lever, lock the spindle, and remove the hexagonal-socket bolt with the Hex. bar wrench.

(3)While holding the lower guard lever to keep the lower guard fully retracted into the saw cover, remove the saw blade.

2.Mounting the Saw Blade

(1)Thoroughly remove any sawdust which has accumulated on the spindle, bolt and washers.

(2)As shown in Fig. 9, the side of Washer (A) with a projected center the same diameter as the inner diameter of the saw blade and the concave side of Washer (B) must be fitted to the saw blade sides.

*Washer (A) is supplied for 2 types of saw blades with the hole diameters of 16 mm and 30 mm. (When buying the Circular Saw, one type of washer (A) is supplied.)

In case the hole diameter of your saw blade does not correspond to that of washer (A), please contact the shop where you purchased the Circular Saw.

(3)To assure proper rotation direction of the saw blade, the arrow direction on the saw blade must coincide with the arrow direction on the saw cover.

(4)Using the fingers, tighten the hexagonal-socket bolt retaining the saw blade as much as possible. Then

depress the lock lever, lock the spindle, and thoroughly tighten the bolt.

CAUTION

After having attached the saw blade, reconfirm that the lock lever is firmly secured in the prescribed position.

MAINTENANCE AND INSPECTION

1.Inspecting the saw blade

Since use of a dull saw blade will degrade efficiency and cause possible motor malfunction, sharpen or replace the saw blade as soon as abrasion is noted.

2.Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.
