PROBLEM
SOLUTION
Motor does not turn on.
1) Check external power source (extension cord, breaker, etc).
2) Loose internal wire. Check and secure if necessary.
3) Motor brushes defective. Replace if necessary.
4) Check to ensure the motor on/off switch is operable. Replace if
necessary.
Excessive sparking
when motor is running.
1) This may indicate the presence of debris in the motor or worn out
carbon brushes. Check the brushes for unusual wear and replace
if necessary. Clean out the internal motor armature if necessary.
2) Armature has a rough edge. Inspect and replace if necessary.
Magnetic does not hold
to work area.
1) Work surface thickness is too small. A minimum of 3/8” (10mm)
continuous ferrous steel must be used for magnetic adhesion.
CAUTION: These drills do not work on sheet metal!
2) Entire magnet base is not on the work surface.
3) Voltage is low at the machine. Check voltage.
4) There is debris or excess material between the work area and the
magnetic base. Clean work area surface.
Hole is not cutting.
1) Cutter is dull. Sharpen or replace.
2) Work area material is not appropriate for cutter type. High carbon
type steels require special cutting bits (tungsten carbide tip, etc).
