DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this instruc-
tion manual may cause serious personal injury.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
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.
Bevel cutting (Fig. 2)
Loosen the knob on the bevel scale plate on the front of
the base. Set for the desired angle (0° – 45°) by tilting
accordingly, then tighten the knob securely.
Adjusting for accuracy of 90° cut (vertical cut)
(Fig. 3 & 4)
This adjustment has been made at the factory. But if it is
off, adjust the adjusting screw with a hex wrench while
squaring the blade with the base using a triangular rule,
try square, etc.
Sighting (Fig. 5)
For straight cuts, align the right edge of the notch in the
front of the base with your cutting line on the workpiece.
For 45° bevel cuts, align the left edge of the notch in the
front of the base 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 &
9)
Use a screwdriver to loosen the two screws which secure
the dust box. Then remove the dust box from the tool.
After removing the dust box, press the shaft lock so that
the diamond wheel cannot revolve and use the hex
wrench to loosen the hex socket head bolt counterclock-
wise.
Then remove the hex socket head bolt, outer flange and
the diamond wheel. To install the diamond wheel, follow
the removable procedure in reverse. BE SURE TO
TIGHTEN THE HEX SOCKET HEAD BOLT SECURELY.
CAUTION:
• Make sure that the arrow on the wheel should point in
the same direction as the arrow on the tool.
• Use only the Makita wrench to install or remove the
wheel.
Rip fence (guide rule) (Accessory) (Fig. 10)
The handy rip fence (guide rule) allows you to do extra-
accurate straight cuts. Simply slide the rip fence up
snugly against the side of the workpiece and secure it in
position with the clamp screw on the front of the base. It
also makes repeated cuts of uniform width possible.
Dust extraction (Fig. 11)
This tool equipped with a dust box to collect dust and cut
chips. When the dust box is about two thirds full, empty
its contents. To do so, press the lever to unlock the dust
cap. Then open it.
Cleaner cutting operations can be performed by connect-
ing this tool to a Makita vacuum cleaner. Remove the
rubber cap from the dust cap and connect the vacuum
cleaner hose to the dust cap.
OPERATION
(Fig. 12)
Grasp the rear handle with your right hand, the front grip
with your left. 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. Move
the tool forward over the workpiece surface, keeping it
flat and advancing smoothly until the cutting is com-
pleted.
To get clean cuts, keep your cutting line straight and your
speed of advance uniform. Never use water when cut-
ting.
Water may enter the tool, causing an electric shock haz-
ard.
CAUTION:
• 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.
