FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before adjusting or checking function on
the tool.
Adjusting the depth of cut
Fig.1
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.
Sighting
Fig.2
Align the notch in the front of the base with your cutting
line on the workpiece.
Switch action
CAUTION:
Before plugging in the tool, always check to see
•
that the switch trigger actuates properly and
returns to the "OFF" position when released.
Fig.3
For tool with lock-off button
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, depress the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
CAUTION:
Do not pull the switch trigger hard without pressing
•
in the lock-off button. This can cause switch
breakage.
For tool without lock-off button
Fig.4
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
Overload protector
Fig.5
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 switch trigger when you press the
restart button, however.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the
tool.
Installing or removing diamond wheel
Fig.6
Loosen the thumb nut, lower the base and tighten the
thumb nut in that position. Fit the socket wrench onto the
hex bolt and turn the diamond wheel until two flatted
parallel surfaces of the outer flange reach the direction
in which the wrench can be inserted.
Fig.7
To install the wheel, follow the removal procedure in
reverse. Always install the wheel so that the arrow on
the wheel points in the same direction as the arrow on
the blade case.
BE SURE TO TIGHTEN THE HEX BOLT SECURELY.
Fig.8
CAUTION:
Use only the Makita wrench to install or remove the
•
wheel.
Dust bag
Fig.9
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.

OPERATION

CAUTION:
Be sure to move the tool 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 tool.
Fig.10
Hold the tool firmly. Set the base plate on the workpiece
to be cut without the wheel making any contact. Then
turn the tool on and wait until the wheel attains full speed.
Move the tool 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.
