by changing the number of the space rings as shown in
the table. (Fig. 8)
Installation (Fig. 9)
Determine the distance of the two blades according to

wrench while pushing down the shaft lock.
Return the cover and the base to the original position and

• When the handle cannot be moved easily, loosen the
bolts furthermore.
• To secure the handle, tighten the two bolts firmly.
2. The front handle can be shifted sideways.
• To shift it, loosen and remove the two bolts on both
sides of the front handle.

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 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.
• Always use the front grip and firmly hold the tool by
both front grip and main handle during operations.
Adjust the front handle to appropriate position for your
work by referring to the "Front handle" in the section
"ASSEMBLY".
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, push down the front handle gently until it
stops and then pull the tool slowly to perform a cut.
(Fig. 14)
Switch off the tool in the position posed when finishing a
cut. Raise the tool after the wheel comes to a complete
stop.
Remove the remaining portion between the two blade
passage by other appropriate tools.
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.
The tool and its air vents have to be kept clean. Regularly
clean the tool's air vents or whenever the vents start to
become obstructed. (Fig. 15)
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 con-
crete block and cut in it.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by Mak-
ita Authorized Service Centers, always using Makita
replacement parts.
