increase the speed until you observe that the plastic is melting at the point of contact. Then
reduce the speed slightly to get the optimum working speed.
Some rules of thumb in regard to speed:
1. Plastic and other materials that melt at low temperatures should be cut at low speeds.
2. Polishing, buffing and cleaning with any type of bristle brush must be done at speeds not
greater than 15,000 RPM to prevent damage to the brush.
3. Wood should be cut at high speed.
4. Iron or steel should be cut at high speed. If a high speed steel cutter starts to chatter — this
normally means it is running too slow.
5. Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various speeds,
depending on the type of cutting being done. Use paraffin or other suitable lubricant on the cutter
to prevent the cut material from adhering to the cutter teeth.
Increasing the pressure on the tool is not the answer when it is not performing as you think it
should. Perhaps you should be using a different accessory, and perhaps an adjustment in speed
would solve the problem. Leaning on the tool does not help.
Maintenance
Service
Warning: Preventive maintenance performed by unauthorized personnel may result in
misplacing of internal wires and components which could cause serious hazard. We
recommend that all tool service be performed by a WEN Service Facility.
Warning: To avoid injury from unexpected starting or electrical shock, always remove
plug from wall outlet before performing service or cleaning.
Carbon brushes
The brushes in your tool have been engineered for many hours of dependable service.
In order to prepare your brushes for use, run your tool at full speed for 5 minutes under no load.
This will properly “seat” your brushes, which extends the life of both your brushes and your tool.
To maintain peak efficiency of the motor, we recommend every 40 - 50 hours the brushes be
examined. Only genuine WEN replacement brushes specially designed for your tool should be
used.
Cleaning
Warning: To avoid accidents always disconnect the tool from the power supply before
cleaning or performing any maintenance. The tool may be cleaned most effectively with
compressed dry air. Always wear safety goggles when cleaning tools with compressed
air.
