 ==== Safety ====
-  * To be written.
   * Be aware of other people around you. Don't bump into them and be respectful of usage space around the equipment.
   * Tie long hair back.
   * Don't wear loose clothing that might catch on any moving part.
+  * Be aware of dust hazards associated with your work piece, including coatings.
+  * Do not operate with dull, cracked or badly worn blade. Inspect blade for cracks and missing teeth before use.
+  * Where gloves only when replacing the blade.
+  * Follow correct positioning of hands and use clamps.
+  * Do not reach over machine while it's running
+  * Do not remove safety devices
+  * Always hold your workpiece securely clamped in place and make sure that it does not come loose when it is being cut.
+  * Allows follow correct positioning of hands
+  * 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.
+  * If moving the equipment make sure this is done by two people.
+  * Don't use the wrong cutting fluid which will lead to chip fire and possible explosion.
+  * Minimise skin contact with cutting fluid
+  * Wear mask and eye protection when using cutting fluid.
+  * Due to friction, the work piece, chips and some machine components can be hot enough to burn you
+  * When doing maintenance make sure no power is reaching the equipment. The lockout box is not a safety device.
 Use the following recommended safety equipment for protection while using this machine:
-  * To be written
   * Safety goggles for eye protection
+  * Ear defenders for noise reduction (noise emission = 78dB at idle speed, workplace limit is 80dB).
+  * Dust masks may be needed depending on materials and their coatings being cut.
+  * Offer PPE to others in the room who may be affected
 ==== 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.
   * The blade specification is: Bandsaw Blade Length: 1,640 mm (64.1/2"). Width: 13mm. 14TPI.
   * Here is a suitable replacement blade from Axminster for £11.  [[https://www.axminstertools.com/axcaliber-high-carbon-blade-1-640mm-64-1-2-x-12-7mm-1-2-x-14-tpi-340686|Axcaliber High Carbon Bandsaw Blade 1,640mm(64.1/2") x 12.7mm 14 Tpi 340686]]

 === 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.

   - Changing the blade requires undoing 10 screws, this is a PITA, a poorly designed process, go carefully, as some parts are not durable.
