Makita CC300D Instruction Manual page 8

• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. If you pull the switch trigger, the
motor runs again but stops soon. In this situation,
remove and recharge the battery.
Adjusting depth of cut (Fig. 2)
CAUTION:
• After adjusting the depth of cut, always tighten the
clamping screw securely.
Loosen the clamping screw on the depth guide and move
the base up or down. At the desired depth of cut, secure
the base by tightening the clamping screw.
Bevel cutting (Fig. 3)
Loosen the clamping screw on the bevel scale plate on
the front of the base. Set for the desired angle (0° - 45°)
by tilting accordingly, then tighten the clamping screw
securely.
Sighting (Fig. 4)
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. 5)
CAUTION:
• Before installing the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
• Do not pull the switch trigger hard without pressing the
lock-off lever. This can cause switch breakage.
To prevent the switch trigger from being accidentally
pulled, a lock-off lever is provided. To start the tool, slide
the lock-off lever and pull the switch trigger. Release the
switch trigger to stop.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Installing or removing diamond wheel
(Fig. 6)
CAUTION:
• When installing the diamond wheel, be sure to tighten
the bolt securely.
• Use only the Makita wrench to install or remove the
diamond wheel.
To remove the diamond wheel, press the shaft lock fully
so that the diamond wheel cannot revolve and use the
wrench to loosen the hex bolt counterclockwise. Then
remove the hex bolt, outer flange and diamond wheel.
(Fig. 7)
To install the diamond wheel, follow the removal
procedure in reverse. Always install the diamond wheel so
that the arrow on the diamond wheel points in the same
direction as the arrow on the diamond wheel case.
BE SURE TO TIGHTEN THE HEX BOLT SECURELY.
(Fig. 8)

NOTE:
• If a inner flange is removed by chance, install the inner
flange so that its protrusion (bigger side) faces inside
as shown in the figure.
Hex wrench storage (Fig. 9)
When not in use, store the hex wrench as shown in the
figure to keep it from being lost.
Installing water supply
Loosen the screw A. Slide the tank holder all the way over
the motor housing. Position the notch of the tank holder
positions just below the screw head as illustrated. Then
tighten the screw A. (Fig. 10)
Attach the tank on the tank holder so that the tank holder
fits between the step and dots. Connect the cap on the
tube end to the mouth of the tank. Turn the tank
clockwise. Then tighten the screw B. (Fig. 11)
Water supply (Fig. 12 & 13)
Be sure that the water supply cock is closed before filling
the tank with water. Open the cap on the tank and fill the
water. Recap the tank.
CAUTION:
• When filling the tank with water, be careful not to let the
tool get wet.
OPERATION (Fig. 14)
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.
Feed water to the wheel by adjusting the water supply
cock to obtain a gentle flow of water. 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.
For fine, clean cuts, cut slowly. (When cutting glass plate
5 mm thick, cut at about 250 mm/min. When cutting tile
10 mm thick, cut at about 300 mm/min.) Also slow down
as you complete a cut to avoid breaking or cracking the
workpiece being cut.
CAUTION:
• Be sure to hold the workpiece firmly down on a stable
bench or table during operation.
• Do not twist or force the tool in the cut, or the motor
may be overloaded or the workpiece may break.
• Do not use the tool with the diamond wheel in an
upward or sideways position.
• The wheel for this tool is a wet-type diamond wheel for
glass and tile applications. Be sure to feed water to the
diamond wheel during operation.
• If the cutting action of the diamond wheel begins to
diminish, dress the cutting edge of the wheel using an
old discarded coarse grit bench grinder wheel or
concrete block. Dress by pressing lightly on the outer
edge of the diamond wheel.
NOTE:
• When the battery cartridge temperature is low, the tool
may not work to its full capacity. At this time, for
example, use the tool for a light-duty cut for a while
until the battery cartridge warms up as high as room
temperature. Then, the tool can work to its full capacity.
