I

Hardwoods, metals, and glass require high

speed operation, and drilling should also be done at high speeds.

The speed of model 395 is controlled by setting

this indicator on the housing.

The Settings for Approximate Revolutions

Per Minute Moto-Tool Variable Speed Model 395.

Switch Setting Speed Range

14,500- 8,000 RPM

29,000-11,000 RPM

312.000-17,000 RPM

418,000-24,000 RPM

525,000-30,000 RPM

NOTE: Speed is affected by voltage changes°

A reduced incoming voltage will slow the

R.P.M. of the tool, especially at the lowest

setting. If your tool appears to be running slow increase the speed setting accordingly.

Ultimately, the best way to determine the correct speed for work on any material is to practice for a few minutes on a piece of scrap, even

after referring to _he chart. You can quickly learn that a slowe? or faster speed is more

effective just by observing what happens as

you make a pass or two at different speeds.

When working with plastic, for example, start at a slow rate of speed and increase the speed until you observe that the plastic is melting at the point of contact. Then back the speed off

sligntly to get the optimum working speed.

Some rules of thumb in regard to speed:

1. Plastic and materials that melt at low

temperatures should be cut at low speeds.

2. :olishing, buffing and cleaning with awire

brush should be done at speeds below

15,000 RPM Io prevent damage to the brush.

If you choose, dial the speed you need on the

single speed model 275 with this table-top

control accessory.

If you need it. single-speedmodels also can

have speed control by the addition of a foot control unit.

The point to remember is this: You can do the

great malonty of work wtth the single speed at

its regular speed of 28,000 RPM. But for

certain materials and t'/pes of work, you need slower speeds - which _sthe reason the variable

speed models and t_e speed control units were de,,'e_c #e_.

3.Soft wood should be cut at high speed.

4.Iron or steel should be cut at top speed if

using atungsten carbide accessory, but at slower speeds if using high speed steel

cutters. If a high speed steel cutter starts

to chatter - this normally means it is running too slow.

5.Aluminum, coplber alloys, lead alloys, zinc alloys, and tin may be cut at any speed,

depending on the type of cutting being

done• Use paraffin or omer suitable

lubricant on the cutter to prevent the cut material from adhering to the cutter teeth.

Increasing the pressure on me tool is not the answer when it is not cutting as you think it

should. Pernaps you should be using a

different cutter, and perhaps an adjustment

in speed would solve the problem. But lean- ing on the tool seldoms helps.
