SIZE OF WIRE
• Use the finest size of wire suitable for the application
• Finer wire size will perform better and last longer than heavier
TROUBLE SHOOTING GUIDE
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.
PROBLEM
RECOMMENDED ACTIONS
Brush is too aggressive
• Increase trim length
• Reduce wire diameter
• Work at lower speed
Brush is not aggressive enough
• Reduce trim length
• Increase wire diameter
• Work at higher speed
Action of brush does not totally
remove scale
• Reduce trim length
• Increase wire diameter
Finish to coarse
• Increase trim length
• Reduce wire diameter
• Work at higher speed
• Choose a nylon abrasive brush
Finish to smooth
• Reduce trim length
• Increase wire diameter
Action of brush is not uniform
• Reduce brushing pressure
• Automatise operations to avoid human inaccuracy
Wire breaks more than usual
• Reduce brushing pressure
• Reduce wire diameter
• Work at lower speed
Life of the brush is too short
• Reduce wire diameter
• Increase brush diameter
• Reduce brushing pressure
Guards
Keep all machine guards in place
Speeds
Observe all speed restrictions indicated on brushes
Protective equipment
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.
SAFETY & STORAGE
Safety goggles or full face shields with side shields must be worn by all operators and others in the immediate
area of power brush operations.
