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.

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
efficient 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.

004380
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.
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.
