Speed selection

Power off and wait for the spindle to stop before moving the levers (plate: "BRYT STRÖMMEN VID VÄXLING").

Lever directions are seen from the front, facing the speed chart. Both levers always point upward — either up-right ↗ or up-left ↖.

Larger drills need lower speeds. Use the drill manufacturer's data for the material. Don't force a lever that won't engage.

Setup

• On/off: motor-protection breaker in the box at the top of the column, in use since 2017 (the original head buttons have been removed). There is no separate emergency stop.

• Quill return: spring-return kit by Mr3D, replacing the original counterweight.

• Ceiling-secured: the drill press is fastened to the ceiling because the floor is thin concrete on sand. Don't move it or detach the fastening; report any looseness.

• Table height: use the crank. Check that no cable is wound around the crank, and never force a locked adjustment. Moving the head requires separate instruction.

• Spindle taper: MT3 according to Arboga's catalogue. Check the actual taper and arbor before buying tooling.

Safety

• Eye and hearing protection. No gloves. Secure hair, sleeves, jewellery.

• Clamp the workpiece and fix the vise/fixture to the table. Never hold work by hand.

• Thin sheet metal can grab and spin as the drill breaks through — e.g. a 16 mm drill in 3 mm stainless has pulled work out of the vise. Clamp sheet firmly with backing and ask for help with large holes.

• Remove the chuck key immediately after use.

• Stop the machine before measuring, adjusting or clearing chips. Never stop the chuck by hand.

How to use

1. Power off: select speed, adjust and lock the table, set the depth stop and check the drill can't reach the vise or table.

2. Clamp the work and secure the vise/fixture. Support long stock.

3. Fit the drill and tighten. Remove the chuck key.

4. Start at the breaker box. Check the drill runs true — stop if it wobbles.

5. Drill with steady feed and cutting fluid where needed. Clear chips from deep holes; ease off at breakthrough.

6. Stop at the breaker box and wait for the spindle to stop.

7. Brush/vacuum chips, return tooling, report faults.

Troubleshooting

Maintenance

• Never fill the gearbox with oil — excess oil reaches the motor and damages it. Lubrication is a few drops of machine oil in the designated oil cups/holes only (instructions p. 2).

• Keep the table, column and tooling clean and dry.

• Internal work, bearings and electrical work are for maintainers.

• Refurbished Feb–Mar 2018 (new SKF bearings, table welded and resurfaced, repainted): refurbishment project.

• Maintenance and repairs log

The E100S is a different 12-speed model — its instructions don't apply.
