The component-life counter

The situation

Illustrative scenario: a photodepilation lamp is replaced every March because that is the established routine. One year the device works far more than usual; another year it works less. A calendar date alone cannot represent both patterns. Manufacturer-rated pulses, cycles or operating hours provide a more relevant maintenance input when they are available and recorded correctly.

The common mistake: maintaining only by calendar or after failure

Some wear parts are governed by time, others by hours, pulses, cycles, condition or a combination of factors. Replacing solely by date can be early or late. The correct basis comes from manufacturer instructions, applicable regulation and a qualified technician — not a generic rule copied from another device.

Replacement parts and consumables belong in the equipment’s total cost of ownership. Tracking them helps the centre budget and evaluate the asset without assuming that a particular component will fail at an exact counter value.

The method: a four-step component register

Build a traceable record for every relevant wear part.

• Inventory components: list lamps, handpieces, heads, filters and other wear parts, together with the manufacturer’s inspection or replacement criteria.
• Record installation: retain the date, part identifier and device counter reading when a new component is fitted.
• Update verified use: record hours, pulses, cycles or other required indicators from the device log or an approved measurement source.
• Plan against the approved threshold: schedule inspection, procurement or replacement using manufacturer and technician guidance. Do not continue merely because a part appears to work, and do not replace a serviceable part solely because of a generic percentage.
