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.
