LEFIS Beauty Equipment Use Precautions & Maintenance Guide

Professional beauty equipment plays a critical role in modern aesthetic treatments—from laser hair removal to slimming, muscle sculpting, tattoo removal, wrinkle reduction, and overall skin rejuvenation. However, even the highest-quality machines require correct operation, safety awareness, and regular maintenance to ensure stable performance, accurate output, and device longevity.

This comprehensive guide explains:

• How to use Lefis beauty equipment safely

• Daily precautions every operator must follow

• Maintenance routines for long-term durability

• Operating techniques for specific machines

• How Lefis treatment systems integrate into professional beauty clinics

Why Proper Use & Maintenance Matters

Lefis machines—including diode lasers, picosecond lasers, Q-switched Nd:YAG devices, RF units, EMS muscle stimulators, cavitation machines, and ultrasonic systems—are high-precision electronic instruments. Their performance depends on:

• Stable energy output

• Clean optical and electrode components

• Moisture-free internal circuits

• Correct operating environment

• Routine maintenance and inspections

Proper care ensures:

Higher treatment effectiveness

Consistent energy output = better client results.

Longer equipment lifespan

Well-maintained machines avoid premature component failure.

Safer treatment outcomes

Dust, oil, or moisture can affect energy delivery and increase risk.

Lower repair cost

Simple preventive measures reduce major maintenance expenses.

General Precautions for All Beauty Equipment

Regardless of the machine category, these fundamental rules apply to every professional device:

1 Storage & Placement

• Avoid moist, humid, or dusty environments

• Keep away from direct sunlight

• Do not store near flammable or explosive items

• Maintain a clean, ventilated, temperature-stable work area

Electronics and lasers are sensitive to heat, moisture, and electromagnetic interference, so proper placement is essential.

2 Keep Surfaces Clean

Cover_UNUSED devices with:

• Flannel cloth

• Gauze

• Dust-proof covers

For cleaning:

• Use a dry or lightly damp cloth (never dripping water)

• Avoid harsh chemicals

• Do not allow moisture to enter connectors or screens

Accessories—probes, patches, electrodes, shovel heads—must be cleaned after each client.

3 Avoid contact with Oil or Corrosive Products

Many accessories must not touch:

• Oily skincare

• Essential oils

• Acidic substances

• Corrosive liquids

These materials may damage:

• Conductive heads

• Ultrasonic probes

• Laser handpieces

• Electrode plates

Always match cosmetics with the requirements of the equipment manual.

4 Protect Cables, Connectors & Power Supply

• Do not pull, twist, or wrap wires tightly

• Avoid stepping on or bending cables

• Keep connectors dry at all times

• Ensure grounding of all equipment

• Use professional voltage stabilizers where recommended

Water entering the device or power system is strictly prohibited.

5 Avoid Electromagnetic Interference

Beauty devices use computer-controlled chips. Avoid using high-frequency electrical appliances nearby such as:

• Hair dryers

• Curling irons

• Microwave beauty devices

• Sterilizers

Interference may cause:

• Temporary freezing

• Screen flickering

• Unexpected restarts

Solution: turn off the power → wait 10 seconds → restart the equipment.

6 No Collision or Impact

Laser components, optical lenses, RF generators, and HIFEM magnetic coils can be damaged by:

• Dropping

• Knocking

• Strong vibration

Handle all devices carefully when moving or storing them.

7 Regular Cleaning & Scheduled Power-On

If a device is unused for long periods:

• Cover with moisture-proof dust bags

• Power on every 15–20 days for 1 hour to prevent internal moisture and aging

• Inspect connectors and filters
