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 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.

OPERATING INSTRUCTIONS
Removing or installing diamond wheel
(Fig. 2, 3 & 4)
Important:
Always be sure that the tool 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.
CAUTION:
Use only the Makita wrench and socket wrench to install
or remove the wheel.
Adjusting depth of cut (Fig. 5)
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.
CAUTION:
After adjusting the depth of cut, always tighten the wing
nut securely.
Dust bag (Fig. 6)
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 tool 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 (Fig. 7)
Align the notch in the front of the base with your cutting
line on the workpiece.
Switch action (Fig. 8)
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the "OFF"
position when released.
To start the tool, simply pull the trigger. Release the trig-
ger to stop.
Overload protector (Fig. 9)
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, how-
ever.
