(Suggested Only) Bandsaw Operation: Jet VBS-18MW

Following my bandsaw induction, I put together the information that was discussed for my own use but thought this may be useful for everyone and belonged in the bandsaw page on the wiki. Steve suggested putting it up here for review.

Basic Operation

1. Initial checks and adjustments (see below).
2. Place access card in reader. Set up guides and blade guide height (see below) as needed.
3. If cutting wood, turn on waste vacuum.
4. Press Start button and move the work to the blade.
5. Press Stop button and wait for blade to stop moving before touching anything.
6. Turn off waste vacuum. (Repeat steps 3-6 as needed).
7. Remove access card, put tools away, and clean up.

Initial Checks & Adjustments

To be performed before your first use every session:

1. Correct blade: Check the blade you need is fitted (wood or metal) and is fitted correctly (cutting direction is down). Measure blade width from back/flat edge to bottom of teeth. Wood blade is 18mm (i.e. Ʃ|←18mm→|) and has fewer teeth-per-cm than metal blade. If not correct, ask a Level 2-rated person to change it for you.
2. Gear position: Check gear lever is pushed in for wood or pulled out for metal (middle is neutral).
3. Vacuum: Check duct is connected, and ensure collector isn't full. Only used if cutting wood.
4. Blade tension: Open top door, inspect gauge and ensure line is just visible below correct blade saw and type. For example, for an 18mm wood blade ensure the "18" line on the Wood scale is just visible above the gauge pointer. Knob on rear locks it in place, wheel on underside of top cabinet adjusts it.
5. Blade alignment: Inspect top-side window to ensure blade is roughly centred on pulley. If not, adjust or seek help.
6. Lower & Upper bearings: Bearing assemblies need have the front edges of the side bearings just behind the teeth, and all bearings 0.4mm (1/64") from the blade. A piece of paper folded twice (4 thicknesses) can be used as a rough feeler gauge. Handle locks assembly in place, wingnuts lock bearings in place, knurled knobs adjust bearing position.
7. Blade guide height: Adjust height of the blade guide (top bearing assembly) to bring it close to the work, but clear of everything on the table: no closer than 5mm (3/16"). Too much height reduces cut accuracy and can damage the blade. Knob on rear locks it in place, wheel on side adjusts it.
8. Final check: Ensure locking handles, wingnuts, and knobs are tightened. Close doors and covers.

Safety & Other Considerations

• The bandsaw and welding machines currently share the same power supply, so only one can operate at the same time. You and the welder may be able to agree to alternate work.
• Use the pusher tools for normal work, but exercise judgement if doesn't need it.
• Always wear safety glasses or goggles. Wear ear defenders if needed.
• Never step away from the machine while the blade is moving.
• Don't rest items on table unless well clear of blade and guides. Keep table clear of offcuts.
• For large or awkward items, use stand rollers to rest the work on. Consider asking someone to help.
• The fence isn't perfectly parallel to the blade, so allow extra material that can be removed later.
• For short items, screw the adapter L-plate (stored on wall ducting at head height) to the fence with the horizontal against the table to allow blade guide to be lowered without fouling the fence.
• Don't use the fence and mitre to create a guide channel. This can bind and damage the blade.
• If cutting a curve or freehand, move the work with the arc's centre away from the blade. Don't twist.
• Manual references: Section 9 for adjustment information and Section 11 for operating information.
