Adjusting depth of cut (Fig. 5)
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.
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 workpiece when
you perform the bevel cut.
Portable residual current device (Fig. 8)
Connect the tool to a power supply and test the portable
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 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 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 exces-
sive, 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. Accumulation of dust
inside the covers may cause a mulfunction 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 con-
crete block and cut in it.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
