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
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
counterclockwise.
Fig.8
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.
Fig.9
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
connecting 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
completed.
To get clean cuts, keep your cutting line straight and
your speed of advance uniform. Never use water when
cutting. Water may enter the tool, causing an electric
shock hazard.
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 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
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
concrete block and cut in it.
Replacing carbon brushes
Fig.13
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.
Fig.14
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers,
always using Makita replacement parts.
