Several factors can influence a brush application. If the selected brush does not achieve the expected
result, the following table may provide solutions for the most common problems faced by a user.
For further information, please contact our technical department.

Reduce wire diameter
Reduce operating speed
Brush is not aggressive enough Reduce trim length

SAFETY & STORAGE
Safety goggles or full face protection with side shields must be worn by all operators and others in the
immediate area of power brush operations.
• Keep all machine guards in place
• Observe all speed restrictions indicated on brushes
• Appropriate protective clothing and equipment must be used
• Brushes should be carefully checked when removed from the original carton. Do not use if rusted
or damaged
• Store brushes in the original carton. Wire brushes should not be exposed to heat, high humidity, acids,
fumes or liquids that can result in deterioration of the wire filaments, and subsequently, premature failure
of the wires. Also, check for distortion of brush fill that can cause imbalance
and excessive vibration when the brush is running
• Check maximum spindle speed. Do not mount and operate the brush if spindle RPM exceeds the
maximum safe free speed for which the brush is rated. Spindle length should be sufficient to permit
a full nut mounting
• Before starting the machine, rotate the wire brush with a gloved hand to determine that the brush has
been correctly mounted and turns freely
