Operation

Palmgren power switch
The power switch on the column adjacent to the table.

This machine has a paddle-type power switch that resembles the switch on the table saws in the Wood Shop.

Pull the paddle out to start.

Push it in to stop.

A paddle switch is useful if the operator's hands are occupied. The machine can be stopped with an elbow of a shoulder if necessary.

Setting the Speed

Always unplug the saw before changing the speed

The Palmgren has a simple belt drive with multiple pulleys, similar to those found in drill presses.

Although a detailed rotary reference table is mounted on the side panel similar to the Do-All, the choices for speeds are limited to certain select values. The Palmgren user manual gives a short table with recommended speeds for metals.

Palmgren metal speeds
Speed ranges for various metals.

To set the saw to the desired speed, refer to the diagram given.

Set the speed-range handle to the correct side. DO NOT leave the handle in-between settings. It must be placed on one side or the other. If there is difficulty setting it in place, rotate the pulley manually until the gears mesh.

Palmgren transmission
Speed-range handle (left) and belts on the Palmgren.

Move the drive belt from one set of grooves on the pulley to another.

Because of the tensioning mechanism, this is a little bit difficult at first, but with a little bit of practice it is not hard to do.
