FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Adjusting the depth of cut (Fig. 1)
Loosen the wing bolt on the depth guide and move the
base up or down. At the desired depth of cut, secure the
base by tightening the wing bolt.
Only in case you adjust the cutting depth to the maximum
one, always be sure to do the depth adjustment after
adjustment of the wheel guard.
Securing wheel guard (Fig. 2)
CAUTION:
• The wheel guard must be adjusted on the tool so that
the closed side of the guard always points toward the
operator.
The wheel guard can be adjusted about 80 degrees, after
you loosen the clamping nut. Adjust to the desired angle,
then secure the clamping nut.
Switch action (Fig. 3)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
For tool with the lock-on switch
To start the tool, simply pull the switch trigger. (A direc-
tion) Release the switch trigger to stop.
For continuous operation, pull the switch trigger (A direc-
tion) and then push in the lock lever. (B direction)
To stop the tool from the locked position, pull the switch
trigger (A direction) fully, then release it.
For tool with the lock-off switch
To prevent the switch trigger from accidentally pulled, a
lock lever is provided.
To start the tool, push in the lock lever (B direction) and
then pull the switch trigger. (Adirection) Release the
switch trigger to stop.
For tool with the lock on and lock-off switch
To prevent the switch trigger from accidentally pulled, a
lock lever is provided.
To start the tool, push in the lock lever (B direction) and
then pull the switch trigger. (A direction) Release the
switch trigger to stop.
For continuous operation, push in the lock lever, (B direc-
tion) pull the switch trigger (A direction) and then push
the lock lever (B direction) further in.
To stop the tool from the locked position, pull the switch
trigger (A direction) fully, then release it.
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 (Fig. 4 & 5)
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 Dolmar wrench to install or remove the
wheel.
Connecting to vacuum cleaner (Fig. 6)
When you wish to perform cleaner operation, connect a
vacuum cleaner to your tool. Connect a hose of vacuum
cleaner to the dust nozzle via an elbow joint (accessory).
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 dia-
mond 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 materi-
als, 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.
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.
