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

CAUTIONS

◯Before starting cutting operation, ensure that the saw blade has reached full speed revolution.

◯Should the saw blade stop or makes 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.

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.

IMPORTANT

Correct connection of the plug

The wires of the mains lead are coloured in accordance with the following code:

Blue: -Neutral

Brown: -Live

As the colours of the wires in the mains lead of this tool may not correspond with the coloured markings identifying the terminals in your plug proceed as follows: The wire coloured blue must be connected to the terminal marked with the letter N or coloured black.

The wire coloured brown must be connected to the terminal marked with the letter L or coloured red. Neither core must be connected to the earth terminal.

NOTE

This requirement is provided according to BRITISH STANDARD 2769: 1984.

Therefore, the letter code and colour code may not be applicable to other markets except the United Kingdom.

Information concerning airborne noise and vibration The measured values were determined according to EN50144.

The typical A-weighted sound pressure level: 91 dB (A).

The typical A-weighted sound power level: 104 dB (A) Wear ear protection.

The typical weighted root mean square acceleration value does not exceed 2.5 m/s2.
