OPERATION
1.
Adjust the groove width as desired.
2.
Adjust the depth of cut.
3.
Mark the intended cutting line.
4.
Place the machine in position on the workpiece.
5.
While it is still raised and the blades are not yet in contact with the workpiece, squeeze the trigger and
allow the machine to reach full speed.
6.
Holding firmly with both hands, squeeze the plunge release lever and slowly lower the blades into the cut,
continuing until the depth stop is reached.Start at the top of the wall and pull the machine downwards.
Take care that the base remains firmly on the workpiece.
CAUTION: Take care not to cut in a curved line. This will likely shatter the diamond blades causing a
severe hazard.
7.
When the cut is finished, raise the machine to the top of its stroke and allow the coasting blade to come
to a full stop before setting down.
Do not force the cut. Let the saw do the cutting at the rate of speed permitted by the type of cut and
workpiece.
SHARPENING DULL DIAMOND BLADES
If a lot of sparks are seen while cutting, this is a sign that the blade is becoming dull. To create better diamond
exposure (sharpen), make several cuts in a special sharpening stone for diamond blades or alternately use
calcareous sandstone.
MAINTENANCE
Every 50 hours of operation blow compressed air through the motor while running at no load to clean out
accumulated dust. (If operating in especially dusty conditions, perform this operation more often.)
KEEP TOOL CLEAN
All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could
possibly dissolve or otherwise damage the material. Wear safety glasses while using compressed air.
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and must be replaced when they reach their wear limit. To
replace: Unplug the machine, remove the 2 socket head limit screws, press the limit pin to open the base, and
