BEFORE OPERATING
Choosing an appropriate saw blade and using the right cutting method is essential to your cutting
efficiency and safety. Select a suitable saw blade and cutting method based on your work material
and job requirements e.g. cutting accuracy, cutting speed, economic concern, and safety control.
Wet cutting
If you choose dry cutting or low ‐ speed cutting, the chips may accumulate in machine parts and may
cause operation failure or insulation malfunction. We suggest you choose wet cutting to avoid
machine damage.
Cutting unknown materials
Before cutting an unknown material, consult the material supplier, burn a small amount of chips from
the material in a safe place, or follow any other procedure to check if the material is flammable.
Never take your eyes off the machine while in operation.
Cutting fluid
For cooling and lubrication purpose, we recommend you use water ‐ soluble cutting fluids. The
following table lists out its pros and cons for your reference.

Before starting a cutting job, make sure there is sufficient amount of coolant in the tank. Check
the fluid level through the sight gauge. Please refer to machine specifications in this manual
