D - Preventive Maintenance; Every Three Months - Technifor XM700 Operating And Maintenance Manual

The maintenance operations listed here are intended as a guideline, and should be implemented upon reception
of the material. In a highly polluted environment, these operations may need to be performed more frequently.
Unplug the power supply plug before beginning any cleaning or maintenance operation (power cable or
battery cable).
Do not apply oil or grease to any element of the stylus or marking head.

1. Every three months

• Clean the point with a dry cloth. Visually inspect the condition of its end.
• To access the point, remove the stylus using a 10 mm open-ended spanner.
Never remove the stylus when it is hot (risk of burns and deformation of the parts).
Never force the 10 mm spanner.
1 : Knurling attachment
2 : 10 mm open-ended spanner
The point must not be nicked. The end radius must be regular. These faults have a direct impact on marking
quality.
- If the point is nicked, the point impact diameters are no longer circular.
- If the point radius is excessively worn, the point impact diameters will be larger. Consequently the line is wider
and shallower, making small characters difficult to read.
• Check the length of the spring housed behind the point.
It should be changed if it measures less than 22 mm (0.866 in). The point could remain embedded in the
material to be marked (excessive marking force in a material that is too soft).
When refitting, do not use the 10 mm spanner. Hand tighten at the knurling
attachment.
