Optional accessory is subject to change without notice.

APPLICATION

Cutting various types of wood.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

2. Power switch

Ensure that the power switch is in the OFF position. If the plug is connected to a power receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3. Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Prepare a wooden workbench (Fig. 1)

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

1. Adjusting the cutting depth

As shown in Fig. 2 cutting depth adjustment can be accomplished by loosening clamp lever and shifting the base. When the base and saw blade are at a perpendicular angle, use the link scale to adjust the cutting depth. Measure the distance that the saw blade extends to adjust the cutting depth to the correct distance because the scale marks are only indicated for reference. After the adjustment is over, securely tighten the clamp lever.

2. Installing riving knife

(1) Place the base facing upward and loosen the clamp

lever. Lift the base until the depth of cut on the main unit reaches the minimum state, fasten the clamp lever, and secure the base. (Fig. 2)

(2) Install the riving knife to the arm securely with the

2 attached bolts. (Fig. 3)

3. Adjusting the riving knife

Loosen the hexagon head bolts used to clamp the riving knife, adjust the riving knife to the position shown in Fig. 4 and securely retighten the bolts. After adjustment, ensure that the riving knife moves by following the adjusted cutting depth.

4. Adjusting the angle of inclination

As shown in Fig. 5 by loosening the wing bolt on the scale and the wing bolt (Fig. 2) on the rear of the base, the saw blade may be inclined to a maximum angle of 45° in relation to the base. Always ensure that the wing bolts are securely tightened after making the desired adjustment.

5. Adjusting the guide (Fig. 6)

The cutting position can be adjusted by moving the guide to the left or right after loosening its wing bolt. The guide can be mounted on either the right or left side of the base.

CUTTING PROCEDURES

1. Place the saw body (base) on the lumber and align the premarked line of cut with the saw blade, using the carved line at the front of the base. Align with the premarked line on the right when not inclined, and at the premarked line on the left at 45° inclined. (Fig. 6)

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.

English

3. Moving the circular saw straight with an appropriate speed will result in optimum cutting.

CAUTIONS

䡬 Before starting cutting operation, ensure that the

saw blade has reached full speed revolution.

䡬 Should the saw blade stop or makes an abnormal

noise during operation, turn off the switch immediately.

䡬 Always take care in preventing the power cord from

coming near the revolving saw blade.

MOUNTING AND DISMOUNTING THE SAW BLADE

CAUTION

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

1. Dismounting the saw blade

(1) Set the cutting depth at maximum, and place the

Circular Saw as shown in Fig. 7.

(2) Depress the lock lever to lock the spindle, and

remove the hexagon head bolt with the provided wrench by turning it counterclockwise.

(3) While holding the safely cover lever to keep it 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) The inside diameter of the saw blade differs according

to the market area the circular saw is sold in.

(a) For mounting saw blade of 25 mm inner

diameters (Fig. 8 (a)), mount the saw blade to washer (A) whose size is identical with the saw blade inner diameter, and the concave side of washer (B) faces the saw blade.

(b) In the case of a saw blade of 30 mm inner

diameter (Fig. 8 (b)), mount the adapter ring to washer (A) whose size is identical with the adapter ring inner diameter and mount the saw blade on the adapter ring, and the concave side of washer (B)) faces the saw blade.

(3) To check proper rotation direction of the saw blade,

the arrow direction on the saw blade must coincide with the arrow direction embossed on the saw cover.

(4) Using the fingers, tighten the hexagon head bolt

retaining the saw blade as much as possible. Then depress the lock lever, lock the spindle, and securely tighten the bolt.

CAUTION

On completion of mounting the saw blade, reconfirm that the lock lever is firmly resumed in the original position.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade:

Since use of a dull saw blade will degrade efficiency and cause possible motor malfunction, resharpen 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 loosened, retighten them immediately. Failure to do so could result in serious hazard.

3. Inspecting the carbon brushes (Fig. 9)

The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon brushes can result in motor trouble, replace the carbon brushes with new ones having the same carbon brush No. shown in the figure when they become worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

4. Replacing a carbon brushes:

Disassemble the brush caps with a screw-driver. The carbon brushes can then be easily removed.

5. Maintenance of the motor

The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

NOTE

Due to HITACHI’s continuing program of research and development, the specifications herein are subject to change without prior notice.
