Adjusting bevel angle
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. (Fig. 6)
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. (Fig. 7)
NOTE:
If the end of the blade case is under the red line on
the depth guide, the outer flange may hit the work-
piece when you perform the bevel cut.
Portable residual current device (Fig. 8)
Connect the tool to a power supply and test the por-
table residual current device (PRCD) before using the
tool. Push the "ON" button and confirm that the pilot
lamp lights. Push the "TEST" button and confirm that
the pilot lamp goes out. Push the "ON" button again
to use the tool.
WARNING:
Do not use the tool if the pilot lamp does not go out
when the "TEST" button is pushed.
Switch action (Fig. 9)
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 trigger from being accidentally pulled,
a lock-off button is provided. To start the tool, press
the lock-off button and pull the trigger. Release the
trigger to stop.
Sighting (Fig. 10)
For straight cuts, align the left edge of the base with
your cutting line on the workpiece. For 45° bevel cuts,
align the left edge of the top guide with it.
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 sim-
ply move the tool forward over the workpiece surface,
keeping it flat and advancing smoothly until the cut-
ting is completed. Keep your cutting line straight and
your speed of advance uniform.
CAUTION:
• THIS TOOL SHOULD ONLY BE USED ON HORI-
ZONTAL SURFACES.
• Be sure to move the tool forward in a straight line
and gently. Forcing and exerting excessive pres-
sure or allowing the wheel to bend, pinch or twist in
the cut can cause overheating of the motor and
dangerous kickback 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 pro-
gressively deeper settings.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
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
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 place its brim below, install it as
far as it will go and secure it by tightening the clamp.
(Fig. 12)
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. Accumu-
lation of dust inside the covers may cause a mulfunc-
tion of the tool. (Fig. 13)
CAUTION:
When using the tool, be sure to attach the covers (A)
and (B).
Replacement of carbon brushed (Fig. 14 & 15)
Replace carbon brushes when they are worn down to
the limit mark. First, remove the cover (A) and then
replace both carbon brushes at the same time. Use
only identical carbon brushed.
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 concrete block and cut in it.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by
a Makita Authorized Service Center.
