by drawing the grinder across the workpiece toward the operator (Fig. 3 direction B). Once the leading edge of the depresssed center wheel is properly abraded, grinding may be conducted in either direction.

4.Switch operation

[When the switch has locking mechanism] Switch ON: To switch on, slide the lock lever in the

direction of A and press the paddle lever in the direction of B as shown in Fig. 4-a. Furthermore, slide the lock lever in the direction of C shown in Fig. 4-bwhile pressing the paddle lever to lock and enable continuous operation.

Switch OFF: To release the locking mode, press the paddle lever in the direction of B shown in Fig. 4-a, and release the paddle lever to switch off.

[When the switch has no locking mechanism] To switch on, slide the lock lever in the direction of A and press the paddle lever in the direction of B as shown in Fig. 4-a. Release the paddle lever to switch off.

NOTE: The paddle lever can not be locked.

5.Precautions immediately after finishing operation After switching off the grinder, do not put it down until the depressed center wheel has come to a complete stop. Apart from avoiding serious accidents, this precaution will reduce the amount of dust and swarf sucked into the grinder.

CAUTION

When the grinder is not in use, the power source should be disconnected.

ASSEMBLING AND DISASSEMBLING THE DEPRESSED CENTER WHEEL (Fig. 1)

CAUTION:

Be sure to switch power OFF and disconnect the attachment plug from the power receptacle to avoid serious trouble.

1. Assembling (Fig. 1)

(1)Turn the grinder upsidedown so that the spindle is facing upward.

(2)Mount the wheel washer onto the spindle.

(3)Fit the protuberance of the depressed center wheel or diamond wheel onto the wheel washer.

(4)Assemble the wheel nut onto the spindle.

(For diamond wheel assembling, use the wheel nut with the convex side against the diamond wheel.)

(5)Insert the push button to prevent rotation of the spindle, and tighten the wheel nut with accessory wrench, as shown in Fig. 1.

2. Disassembling

Follow the above procedures in reverse.

CAUTIONS:

◯Confirm that the grinder wheel is mounted firmly.

◯Confirm that the spindle lock mechanism is disengaged by pushing push button two or three times before switching the grinder on.

MAINTENANCE AND INSPECTION

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. 5)

The Motor employs carbon brushes which are consumable parts.

When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-shop carbon brush is equipped, the motor will stop automatically.

At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

4.Replacing a carbon brush (Fig. 6)

<Disassembly>

(1)Loosen the D4 tapping screw retaining the tail cover and remove the tail cover.

(2)Use the auxiliary hexagonal wrench or small screwdriver to pull up the edge of the spring that is holding down the carbon brush. Remove the edge of the spring toward the outside of the brush holder.

(3)Remove the end of the pig-tail of the carbon brush from the terminal section of brush holder and then remove the carbon brush from the brush holder.

<Assembly>

(1)Insert the end of the pig-tail of the carbon brush in the terminal section of brush holder.

(2)Insert the carbon brush in the brush holder.

(3)Use the auxiliary hexagonal wrench or small screwdriver to return the edge of the spring to the head of the carbon brush.

(4)Mount the tail cover and tighten the D4 tapping

screw.

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.

Information concerning airborne noise and vibration

The measured values were determined according to EN50144.

The typical A-weighted sound pressure level: 85 dB (A).

Wear ear protection.

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

1.Inspecting the depressed center wheel

Ensure that the depressed center wheel is free of

cracks and surface defects.
