ADDITIONAL SAFETY RULES

1. Check the wheel carefully for cracks or damage before operation. Replace cracked or damaged wheel immediately.
2. Use only flanges specified for this machine.
3. Be careful not to damage the spindle, flanges(especially the installing surface) or bolt. Damage to these parts could result in wheel breakage.
4. Hold the machine firmly.
5. Keep hands away from rotating parts.
6. Make sure the wheel is not contacting the workpiece before the switch is turned on.
7. Wait until the wheel attains full speed before cutting.
8. Stop operation immediately if you notice anything abnormal.
9. Do not attempt to lock the trigger in the ''ON''position.
10. Never attempt to cut with the machine held upside down in a vise. This can lead to serious accidents, because it is extremely dangerous.

OPERATING INSTRUCTIONS

Removing or installing diamond wheel

Always be sure that the machine is switched off and unplugged before removing or installing the wheel. Remove the blade cover.

Hold the outer flange with the wrench and loosen the hex bolt clockwise with the socket wrench. Then remove the hex bolt, outer flange and wheel. To install the wheel, follow the removal procedure in reverse.

BE SURE TO TIGHTEN THE HEX BOLT SECURELY.

Use only the Makita wrench and socket wrench to install or remove the wheel.

Adjusting depth of cut

10. Wing nut
11. Base

Loosen the wing nut on the depth guide and move the base up or down. At the desired depth of cut, secure the base by tightening the wing nut.

After adjusting the depth of cut, always tighten the wing nut securely.

Dust bag

12. Dust spout

The use of the dust bag makes cutting operations clean and dust collection easy. To attach the dust bag, fit it onto the dust spout. When the dust bag is about one-third full, remove the dust bag from the machine and pull the fastener out. Empty the dust bag of its contents, tapping it lightly so as to remove particles adhering to the insides which might hamper collection.

Sighting

Align the notch in the front of the base with your cutting line on the workpiece.

Switch action

13. Switch trigger

Before plugging in the machine, always check to see that the switch trigger actuates properly and returns to the ''OFF'' position when released.

To start the machine, simply pull the trigger. Release the trigger to stop.

Overload protector

14. Restart button

The overload protector automatically cuts out to break the circuit and the button pops out, whenever heavy work is prolonged. Wait 20 – 30 seconds before pressing the restart button to resume operation. Your finger should not be on the trigger when you press the restart button, however.

Operation

Hold the machine firmly. Set the base plate on the workpiece to be cut without the wheel making any contact. Then turn the machine on and wait until the wheel attains full speed. Now simply move the machine forward over the workpiece surface, keeping it flat and advancing smoothly until the cutting is completed. Keep your cutting line straight and your speed of advance uniform.

Be sure to move the machine forward in a straight line and gently. Forcing and exerting excessive pressure or allowing the wheel to bend, pinch or twist in the cut can cause overheating of the motor and dangerous kickback of the machine.

MAINTENANCE

Always be sure that the machine is switched off and unplugged before carrying out any work on the machine.

Replacement of carbon brushes

15. Limit mark
16. Brush holder cap
17. Screwdriver

Replace carbon brushes when they are worn down to the limit mark. Both identical carbon brushes should be replaced at the same time.

After use

After use, remove dust from the inside of the machine by running the machine at an idle for a while. Accumulation of dust in the motor may cause a malfunction of the machine.

To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by Makita Authorized Service Center.
