Sandstone Cheveux
Sandstone · Model Cheveux
• "Smooth Flow Technology"/10p Technology - Patients feel gentle heating over the skin with smooth flowing passes of 10 pulses per second of a lower fluence energy that causes a gradual thermal reconditioning shut-down of the cellular structure that causes unwanted hair to grow in the base of the follicle. • Standard Hair Removal - Operators can choose from 6 different hertz rates • One Pulse Lesion Removal - One Pulse mode is utilized for vascular and pigmented lesion removal. • Large Spot Size - The Cheveux sports a large 10 x 14mm spot size that allows the technician to quickly cover large areas of the body. • Easy To Use Delivery System - A comfortable fiber-optic delivery system of the laser energy allows for the operator to effortlessly adapt the movement of a light-weight handpiece over any anatomic location. • The Cheveux Box - The narrow and portable configuration of the Cheveux allows for “uncramped” utilization in small treatment rooms and permits the laser to be easily moved around a physician’s office. • Affordable - Requiring no consumables or disposables, the Cheveux is an affordable entrance or replacement laser into the hair removal market.
Key tips
- ·Verify true laser output with an external power meter, not the console readout - the display drifts independently of real delivered energy.
- ·Never bypass a door interlock, key switch, or footswitch safety to finish a treatment - laser safety interlocks are not optional.
- ·Most low-output complaints trace to the delivery fiber or handpiece, not the laser source - inspect and swap those first.
- ·Intermittent mid-treatment shutdowns are usually cooling-related - check coolant level and flow before suspecting the diode or lamp.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Laser diode / gain medium degradation
HighSymptoms: Reduced output power, inconsistent treatment fluence.
Root cause: Normal diode/gain-medium wear over lamp/diode hours.
Cooling system fault
HighSymptoms: Overheat shutdown mid-treatment, error code on startup.
Root cause: Coolant pump, TEC element, or filter degradation.
Handpiece / delivery fiber wear
MediumSymptoms: Uneven beam delivery, connector arcing, or no output at the handpiece.
Root cause: Fiber or articulated-arm optics degraded by flex/heat cycling.
Interlock / shutter fault
MediumSymptoms: Won't fire, safety interlock fault on the display.
Root cause: Door/footswitch interlock or shutter mechanism failure.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Laser output power verification against a calibrated external power meter
- ·Cooling-system check: coolant level, flow rate, and filter / heat-exchanger condition
- ·Delivery-system inspection: handpiece, delivery fiber or articulated arm, and output optics
- ·Interlock, key-switch, emergency-stop, and footswitch function test
- ·Beam-alignment and optical-path check per the service manual
- ·Annual full PM and electrical safety test
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Laser diode / gain medium degradation
- Confirm the presentation - typically reduced output power, inconsistent treatment fluence.
- Check the most likely cause first: normal diode/gain-medium wear over lamp/diode hours.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the laser diode / flashlamp module per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Cooling system fault
- Confirm the presentation - typically overheat shutdown mid-treatment, error code on startup.
