Gearbox oil change. Loosen 2 screws on the left edge of right top cover. Remove top 2 screws on the right side. Loosen bottom 2 screws on the right side cover. Slide top cover towards the center of the saw. Pivot the right cover down. Remove drive belt. Remove gearbox step pulley. Remove 3 bolts holding the gearbox. These are near the ring gear teeth. Remove the gearbox out the top of the saw between the two transverse brackets (long shaft comes out last). Drain/fill bolt is on the side opposite the pinion gear. Consider replacing the gaskets on the gearbox.

== Auth/Use Notes ==
These notes are for authorized users and authorizers; you must be authorized on the tool by a person, not this list. Don't expect this list to be complete or authoritative.
* Horizontal band saws cut via a vertically descending blades.
* The cutting tooth speed is set by a pulley in the rear.
** Lift up on the motor to get some slack on the belt.
** Don't cross wheels; keep the pulley belt straight.
** Go toward larger motor wheels for soft metals and plastic and smaller motor wheels for tough metals like steel (and tool steel.)
* The cutting tooth feed is set by a needle valve and a weight on top.
** Be gentle with the needle valve; a single finger with light pressure is enough to adjust it.
* Power
** The plug is a twist-lock 220V three-phase plug.
** The starter is located on the back. If you turn on the machine and it makes a buzzing noise, turn it off immediately and turn off/on the starter.
** During use, the on/off switch at the end of the machine is used for power. The trip lever also activates this same switch.
** Turn off switches and unplug the machine when you're done to prevent accidental activation.
** Never walk away from the machine while it's running. We are not a production shop; babysit the machine in case it fails and avoid putting curious people in danger.
* Clamping a workpiece
** Short pieces cock the vice jaws. This ruins the grip on the workpiece and is to be avoided.
** Use a similarly wide piece on the other side of the vice jaw to prevent the jaw from cocking.
** Check the width of your workpiece against the teeth.
*** The thinnest section of the workpiece should be wider than three teeth in a row.
*** The thickest section of the workpiece should be narrow than twenty-four teeth.
** If you're cutting angle stock, rotate it so that it forms a < shape to prevent it from rotating.
** If you're cutting round, use angle blocks (in the tooling cabinet) to keep it from rotating.
** Check that the movable blade guide is as close as possible while clearing the vice and the table.
* Safety
** Unplug the machine before adjusting the pulley or changing the blade.
** Never leave the machine while running. We aren't a production shop; you need to be right by the machine in case something goes wrong or if a curious person walks by.
* Clean up when you're done. Don't leave stock in the machine; don't leave chips and coolant behind. Use a small bucket to catch chips before they hit the ground.
