Adjusting the depth of cut (Fig. 1)
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.
CAUTION:
• After adjusting the depth of cut, always tighten the lever
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 without the lock button
To start the tool, simply pull the switch trigger. Release the
switch trigger to stop. (Fig. 4)
For tool with the lock button
To start the tool, simply pull the switch trigger. Release the
switch trigger to stop. For continuous operation, pull the
trigger and then push in the lock button. To stop the tool
from the locked position, pull the trigger fully, then release
it.
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, press in the lock-off button and then 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.
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. 5)
Hold the outer flange with the offset wrench and loosen
the hex bolt counterclockwise with the socket wrench.
Then remove the hex bolt, outer flange and diamond
wheel.
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. 6)
CAUTION:
• Use only the Makita wrench to install or remove the
wheel.
The inner flange has a 25 mm diameter on one side and
25.4 mm diameter on the other. The side with 25.4 mm
diameter is marked by “25.4”. Use the correct side for the
hole diameter of the wheel you intend to use. Mounting
the wheel on the wrong side can result in dangerous
vibration. (Fig. 7)
Water flow (Fig. 8)
Attach the vinyl tube onto the water pipe and attach the
adapter on the vinyl tube to a faucet of water mains
pressure. Adjust the amount of water flow by simply
adjusting the water cock.
OPERATION (Fig. 9)
Adjust the amount of water flow. 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. Now simply 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.
CAUTION:
• THIS TOOL SHOULD ONLY BE USED ON
HORIZONTAL SURFACES.
• 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.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
After use
Blow away dust from the inside of the tool by running the
tool at an idle for a while. Brush off accumulation of dust
on the base. Accumulation of dust in the motor or on the
base may cause a malfunction of the tool.
Cleaning covers (Fig. 10)
When accumulation of dust on the cover (A) looks
excessive, loosen the clamp and remove the cover (A).
Wash off accumulation of dust inside the cover (A) and
wipe it. Then hold the cover (A) with its brim facing below,
push it as far as it will go and secure it by tightening the
clamp.
When changing the wheel, clean the cover (B) at the
same time. Loosen the screw securing the cover (B) and
remove the cover (B). Wash off accumulation of dust
inside the cover (B) and wipe it. Then attach the cover (B)
to the tool by tightening the screw. Accumulation of dust
inside the covers may cause a malfunction of the tool.
(Fig. 11)
CAUTION:
• When using the tool, be sure to attach the covers (A)
and (B).
