Adjusting the depth of cut (Fig. 2)
Loosen the wing bolt on the depth guide and move the
base up or down. At the desired depth of cut, secure the
base by tightening the wing bolt.
CAUTION:
• After adjusting the depth of cut, always tighten the wing
bolt securely.
Adjusting bevel angle (Fig. 3 & 4)
Loosen the wing nut on the bevel scale plate on the front
of the base. Set for the desired angle (0° - 45°) by tilting
accordingly, then tighten the wing nut securely.
Loosen the wing bolt on the depth guide and move the
base so that the end of the blade case is above the red
line on the depth guide. Then tighten the wing bolt to
secure the base.
NOTE:
• If the end of the blade case is under the red line on the
depth guide, the outer flange may hit the workpiece
when you perform the bevel cut.
Sighting (Fig. 5)
For straight cuts, align the "A" position on the front of the
base with your cutting line. For 45° bevel cuts, align the
"B" position with it.
Switch action (Fig. 6)
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 prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, push in the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
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. 7 & 8)
Hold the outer flange with the wrench and loosen the hex
socket head bolt clockwise with the hex wrench. Then
remove the hex socket head bolt, outer flange and dia-
mond wheel.
Install the diamond wheel, outer flange and hex socket
head bolt onto the spindle. Hold the outer flange with the
wrench and tighten the hex socket head bolt counter-
clockwise with the hex wrench. BE SURE TO TIGHTEN
THE HEX SOCKET HEAD BOLT SECURELY.
CAUTION:
• Use only the Makita wrench to install or remove the
wheel.
Installing water pipe (Fig. 9)
First, unplug the tool. Loosen the wing bolt on the depth
guide and move the base down. Install the water pipe on
the blade case using the screw.
Attach the vinyl tube onto the water pipe and attach the
adapter on the vinyl tube to a faucet of water mains pres-
sure. Adjust the amount of water flow by simply adjusting
the water cock.
Installing cover (A) (Fig. 10)
Install the cover (A) on the tool so that its side with
"Upside " mark faces upward.
OPERATION (Fig. 11)
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 HORIZON-
TAL 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 kick-
back of the tool.
• Since excessive cutting may cause overload of the
motor, the depth of cut should not be more than 20 mm
at a pass. When you wish to cut more than 20 mm
deep, make a couple of passes with progressively
deeper settings.

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.
Dressing diamond wheel
If the cutting action of the diamond wheel begins to
diminish, use an old discarded coarse grit bench grinder
wheel or concrete block to dress the diamond wheel. To
do this, tightly secure the bench grinder wheel or con-
crete block and cut in it.
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. 12 & 13)
When accumulation of dust on the cover (A) looks exces-
sive, loosen the clamp and remove the cover (A). Wash
off accumulation of dust inside the cover (A) and wipe it.
Then install the cover (A) on the tool so that its side with
"Upside " mark faces upward. Push the cover (A)
toward the motor as far as it will go and secure it by tight-
ening 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.
CAUTION:
• When using the tool, be sure to attach the covers (A)
and (B).
