tion) 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 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 dan-
gerous.
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 (2-3/8”). When you need to cut a workpiece
over 60 mm (2-3/8”) up to 100 mm (4”), make more
than two passes of cuts. The depth of the most effi-
cient cut is about 40 mm (1-9/16”).
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.
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 on the position posed when finishing a
cut. Raise the tool after the wheel comes to a complete
stop.
