11 1663 DBS 3600 BRUSH GRINDER KIT - CORRECT APPLICATION 100% 50% 0% 100% Phase 1 Phase 2 Phase 3 Red Curve: DBS 3500 Wirebrush Blue Curve: Nylon Abrasive Disc When treating edges, apply the device only length wise along the edge. Correct Application. Example 2: Example 1: Apply at 90 o to the surface! Avoid applying too much pressure. Correct Application. 1 2 3 Steps Phase 1 The wire brush delievers optimal performance; removal is very good even though only light pressure is applied. The wires are sharp and straight. They do not break off. Phase 2 The once sharp wire-tips are blunt. An effort was made to compensate for declining removal performance by applying more pressure to already broken off tips. Phase 3 If the brush is not replaced during Phase 2, and the application pressure is further increased it will soon be in this condition.  Almost all the wires are bent to extreme. Please note: Wear of a nylon abrasive disc is fairly constant (see diagram), ie: it can be seen how long it has been in service and how much longer it lasts. In contrast, Phase 1, during which the wire brush maintains optimal performance, lasts a very long time. It is almost impossible to see how much work the brush has already done. The transition to Phase 2, and shortly thereafter to Phase 3, happens without notice, but this is perfectly normal. Our Tip: If removal performance declines, inspect the brush, and if Phase 2 has been reached, insert a new brush. Increased pressure and incorrect application (such as eg: 1 and 2) lead to a reduction in Phase 1. Service life of the wirebrush can be extended by repeated sharpening. To sharpen a brush, insert it the other way round and sharpen it on the grinding stone. NZ. pub. 09/14©
