ASSEMBLY
CAUTION:
•
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing the wheel
To remove the wheel, depress the shaft lock to hold the
shaft stationary, then loosen the hex bolt clockwise with
the socket wrench.
To install a wheel, place flange with its partly elevated
side facing the tool, and then place ring before installing
a wheel onto the spindle (shaft) and another flange with
partly elevated side facing outward.
Be sure to fully tighten the hex bolt counterclockwise after
mounting the new wheel, or operation will be dangerous.

Fig.5
CAUTION:
•
Use only the Makita wrench to install or remove
the wheel.
OPERATION
CAUTION:
Be sure to pull the tool when cutting a workpiece.
•
Use this tool for straight line cutting only. Cutting
curves can cause stress cracks or fragmentation
of the diamond wheel and abrasive cut-off wheel
resulting in possible injury to persons in the vicinity.
•
After operation, always switch off the tool and wait
until the wheel has come to a complete stop
before putting the tool down.
•
When cutting concrete blocks, tiles or masonry
materials, do not make a cut in depth more than 60
mm. When you need to cut a workpiece over 60 mm
up to 100 mm, make more than two passes of cuts.
The depth of the most efficient cut is about 40 mm.
Hold the tool firmly with both hands. First keep the wheel
without making any contact with a workpiece to be cut. Then
turn the tool on and wait until the wheel attains full speed.
Fig.6
The cut is made by pulling the tool toward you (not by
pushing away from you). Align the notch on the base
with your cutting line when performing a cut.
Switch off the tool in the position posed when finishing a cut.
Raise the tool after the wheel comes to a complete stop.
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.7
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically
shut off the motor. When this occurs, both carbon
brushes should be replaced. 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.
Pick up an end of the dust cover slightly with hands so
that brush holder cap appears.
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.8
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.
