be performed by drawing the grinder across the
workpiece toward the operator (

Fig. 1 direction B

).

Once the leading edge of the depressed center
wheel is properly abraded, grinding may be con-
ducted in either direction.

4. Precautions immediately after finishing operation

After switching off the machine, do not put it down
until the depressed center wheel has come to a
complete stop. Apart from avoiding serious acci-
dents, this precaution will reduce the amount of
dust and swarf sucked into the machine.

CAUTION

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

DEPRESSED CENTER WHEEL ASSEMBLY

1. Assembling (Fig. 2)

(1) Turn the machine upsidedown so that the spindle

is facing upward.

(2) Align the oval-shaped indentation of the wheel

washer with the notched part of the spindle, then
attach them.

(3) Fit the protuberance of the depressed center wheel

onto the wheel washer.

(4) Screw the wheel nut onto the spindle.
(5) While pushing the lock plate with one hand, lock

the spindle by turning the grinding wheel slowly
with the other hand.
Tighten the wheel nut by using the supplied wrench
as shown in 

Fig. 2

.

2. Disassembly

Follow the above procedures in reverse.

MAINTENANCE AND INSPECTION

1. Inspecting the depressed center wheel

Ensure that the depressed center wheel is free of
cracks and surface defects.

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. Fail-
ure to do so could result in serious hazard.

3. Inspecting the carbon brushes (Fig. 3)

The motor employs carbon brushes which are con-
sumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with a new one having the same carbon
brush No. shown in the figure when it becomes
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 brush:

Disassemble the brush cap with a minus-head screw-
driver. The carbon brush can then be easily re-
moved.

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

IMPORTANT

Correct connection of the plug
The wires of the main lead are coloured in accordance
with the following code:

Blue:

- Neutral

Brown:

- Live

As the colours of the wires in the main 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: 84 dB (A).
Wear ear protection.

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