PREPARATION FOR USE
The selection of an appropriate saw blade and cutting method is important for cutting, work
safety and efficiency. Select an appropriate saw blade and cutting method by fully considering the
work to be cut and the requirements of your job(such as cutting accuracy, cutting speed, economy, and
safety control).
Cutting method:
If you choose dry cutting and low speed of saw blade, the chips may accumulate in machine parts and
may cause the operation or insulation failure of the machine. We suggest you choose wet cutting to
avoid machine damage. You can refer to section
7.2 for experience data..
Cutting unknown materials:
Before cutting an unknown material, consult the supplier of the material, burn a small amount of chips
from the material in a safe place, or follow any other procedure to check to see if the material is
flammable or not.
CAUTION: Never take eyes away from machine during cutting operation.
Cutting oil:
If economics are not of critical concern, you can try oil-based cutting fluids. We always suggest you to
use water-soluble cutting fluids. The comparison table for it is as follows:
