BREAKING ‐ IN THE BLADE
When a new saw blade is used, be sure to first break in the blade before using it for actual, extended
operation. Failure to break in the blade will result in less than optimum efficiency. To perform this
break ‐ in operation, the following instructions should be followed:
Step 1 ‐ Reduce the blade speed to one ‐ half of its normal setting.
Step 2 ‐ Lengthen the cutting time to 2 ‐ 3 times of what is normally required.
Step 3 ‐ Start the break ‐ in operation.
Step 4 ‐ After the break ‐ in operation is completed, set all parameters back to normal settings.
TEST ‐ RUNNING THE MACHINE
Test ‐ running this machine can ensure good machine performance in the future. We suggest you run

Testing machine performance:
Turn on the power and run a basic performance test after you finish installing the machine. Follow
these steps to test machine performance:
Step 1 – Disassemble shipping brackets and bolts.
Step 2 – Install roller table (optional).
Step 3 – Turn on the relay switch in the control box.
Step 4 – Elevate the saw bow. (If your coolant pump is in reverse and the machine cannot run, please
change the electrical phase.)
Step 5 – After the saw bow ascends, extend the quick approach device.
Step 6 – Remove the rust ‐ prevention grease with cleaning oil or kerosene.
Step 7 – Start the coolant pump.
Step 8 – Test these functions under manual mode:

