Machine Setup

The saw delivered to you has been adjusted at the factory. A number of test pieces have been cut using the saw to verify the accuracy of cutting. Therefore, the only setup operations required before releasing the saw for service are spotting the saw and establish- ing the electrical connections to the motor.

Uncrating and Spotting

Spot the saw where it makes the most sense for the operations you will probably be doing. If you are go- ing to be doing cut-off work on very long pieces of stock, allow plenty of room for the stock, and the infeed and outfeed supports. Remove the saw from the ship- ping skid and discard any hold-down devices that were used to secure the saw to the skid.
