• Due to our continuing program of research and devel-

opment, the specifications herein are subject to change

without notice.

• Note: Specifications may differ from country to country.

Power supply

The tool should be connected only to a power supply of

the same voltage as indicated on the nameplate, and can

only be operated on single-phase AC supply. They are

double-insulated in accordance with European Standard

and can, therefore, also be used from sockets without

earth wire.

For public low-voltage distribution systems of

between 220V and 250V

Switching operations of electric apparatus cause voltage

fluctuations. The operation of this device under unfavor-

able mains conditions can have adverse effects to the

operation of other equipment. With a mains impedance

equal or less than 0.31 Ohms it can be presumed that

there will be no negative effects. The mains socket used

for this device must be protected with a fuse or protective

circuit breaker having slow tripping characteristics.

Safety hints

For your own safety, please refer to the enclosed safety

instructions.

ADDITIONAL SAFETY RULES

ENB051-1

1. Check the wheel carefully for cracks or damage

before operation. Replace cracked or damaged

wheel immediately.

2. Use only flanges specified for this tool.

3. Be careful not to damage the spindle, flanges

(especially the installing surface) or bolt. Dam-

age to these parts could result in wheel break-

age.

4. Hold the tool firmly.

5. Keep hands away from rotating parts.

6. Make sure the wheel is not contacting the work-

piece before the switch is turned on.

7. Wait until the wheel attains full speed before cut-

ting.

8. Stop operation immediately if you notice any-

thing abnormal.

9. Do not attempt to lock the trigger in the “ON”

position.

10. Never attempt to cut with the tool held upside

down in a vise. This can lead to serious acci-

dents, because it is extremely dangerous.

(Fig. 1)

11. Before setting the tool down after completing a

cut, be sure that the wheel has come to a com-

plete stop.

12. Do not stop the wheel by lateral pressure on the

disc.

13. The tool must be used only for dry cutting. Do

not use water.

OPERATING INSTRUCTIONS

Removing or installing diamond wheel

(Fig. 2, 3 & 4)

CAUTION:

Always be sure that the tool is switched off and

unplugged before removing or installing the wheel.

Use a screwdriver to loosen the two screws which secure

the dust box. Then remove the dust box from the tool.

After removing the dust box, press the shaft lock so that

the diamond wheel cannot revolve and use the hex

wrench to loosen the hex socket head bolt counterclock-

wise. Then remove the hex socket head bolt, outer flange

and the diamond wheel. To install the diamond wheel, fol-

low the removal procedure in reverse.

BE SURE TO TIGHTEN THE HEX SOCKET HEAD

BOLT SECURELY.

CAUTION:

• Make sure that the arrow on the wheel should point in

the same direction as the arrow on the tool.

• Use only the Makita hex wrench to install or remove the

wheel.

Adjusting depth of cut (Fig. 5)

Loosen the lever on the depth guide and move the base

up or down. At the desired depth of cut, secure the base

by tightening the lever.

Bevel cutting (Fig. 6)

Loosen the knob on the bevel scale plate on the front of

the base. Set for the desired angle (0 – 45°) by tilting

accordingly, then tighten the knob securely.
