Troubleshooting

PROBLEM
1. Wrong tension.
2. Over working blade.
3. Wrong blade application.
4. Twisting blade in wood.
5. Incorrect teeth per inch.
1. Defective cord or plug.
2. Defective motor.
3. Defective wire connections.
4. Brushes worn.
1. Improper mounting of saw.
2. Unsuitable mounting surface.
3. Loose table or table resting
against motor.
REMEDY
1. Adjust blade tension, see "REMOVING AND
INSTALLING BLADES," Page 12 (Pin End) or (Plain
End).
2. Reduce feed rate, see "BASIC SCROLL SAW
OPERATION," Page 11.
3. Use narrow blades for cutting thin wood, wide
blades for thicker wood.
4. Avoid side pressure on blade.
5. Blade should have minimum 3 teeth in contact with
workpiece.
1. Replace defective parts before using saw
again.
2. & 3. Consult Dremel Service. Any attempt to
repair this motor may create a HAZARD
unless repair is done by a qualified service
technician.
4. Replace both brushes.
1. See "MOUNTING YOUR SCROLL SAW," Pages 15
& 16.
2. The heavier your work bench is, the less vibration
will occur. A plywood workbench will not be as good
a work surface as the same size solid lumber. Use
common sense in choosing a mounting surface.
3. Tighten table lock knob.
