   * NEVER hold the workpiece with your hands during a cut
   * Always support work piece with table, vice or some type of support fixture.
+  * Support long materials properly so the machine does not get pulled over. Weight of equipment is >75 kg.

 ==== Bandsaw blades ====
+  * Inspect the blade before use, check  it is the correct type of blade with no cracks or missing teeth
+  * When replacing the blade wear gloves and safety specs and make sure the teeth are facing towards the workpiece.

 === Preparation ===
-  * To be written.
+  * To be written. Some notes below.
+  * The vice truck can be engaged/disengaged with the leadscrew by rotating the cam-shaped sleeve around the screw underneath the truck.
+  * The saw can be angled up out of the way of the workpiece by pulling it up by the handle at the end, and held in one of three positions using the pin mechanism on the rear near the pivot.
+  * This is a hands-off machine when cutting. If you are holding something, stop, you’re using it wrong.
 === Cutting ===
-  * To be written.
+  * To be written. Some notes below.
+  * Set the saw to the appropriate speed using the belt drive gearbox. The belt is tensioned by the motor pivoting with a hex bolt pushing the motor outwards. That bolt will need to be relaxed to move the belt and then reapplied to re-tension. See manual for a table of speeds for various materials.
+  * Twist the hydraulic knob to zero flow. Disengage the pin and lower the saw till the weight is taken by the hydraulic system.
+  * Now lower the saw to above the workpiece by twisting the knob to control the rate of descent.
+  * Perform the cut – likely a very slow rate of descent.
+  * Oh! The blade has stopped but the machine continues. Perhaps the rate of descent was too fast. Regardless of cause, the blade likely has come off its pulleys. The black sheet metal cover on the rear of the saw will need to come off, the blade tension pulley position relaxed, the blade put back on, and re-tensioned. You will want to have looked at the manual, and be wearing gloves.
