Care Information
Climbing, professional, and rescue equipment are investments in your safety. Proper maintenance ensures optimal performance and extends the lifespan of your gear.
- Sport Climbing Equipment
Harness
- Clean with clean water and mild soap (pH neutral). Avoid harsh detergents or bleach.
- Dry in the shade, away from direct sunlight and heat sources.
- Check regularly: seams, buckles, and webbing for signs of wear, tears, or damage.
- Store in a dry, cool place, away from chemicals, oils, and UV rays.
- Replace the harness if it has been dropped under a heavy load (high fall factor), shows visible damage, or is more than 10 years old from the date of manufacture.
Tali / Rope
- Wash with cold water and a special rope wash. Rinse thoroughly.
- Air-dry; avoid tumble dryers and direct sunlight.
- Store in a rope bag or loosely coiled in a cool, dry place.
- Avoid contact with chemicals, acids, bases, and oils.
- Check periodically for core damage, sheath wear, and stiff spots.
- Retire the rope after a high fall factor, if damage to the sheath or core is visible, or as recommended by the manufacturer.
Carabiner & Hardware
- Clean with clean water and a soft brush. Dry thoroughly before storing.
- Lubricate the valve spring with a dry lubricant if it feels stiff.
- Check: that the valve is working properly, and inspect the seat and locking mechanism, as well as the surfaces, for any signs of cracks or corrosion.
- Do not use a carabiner that has fallen from a significant height or appears to be cracked or bent.
Climbing shoes
- Wipe clean with a damp cloth after use. Avoid soaking in water.
- Dry in the shade in a well-ventilated area.
- Store in a cool, dry place; avoid excessive pressure, which may cause the shoes to lose their shape.
- The soles can be re-soled by a professional climbing shoe technician when the rubber begins to wear thin.
- Professional / Industrial Rope Access
PPE (Personal Protective Equipment)
- Follow the maintenance standards set out in EN 365 and the manufacturer’s guidelines for each item of equipment.
- Record every use in the equipment log book — date, condition and any incidents.
- Carry out a pre-use inspection before each use and periodic inspections by a Competent Person.
- Store separately from chemicals, heat and other sources of contamination.
Descender & Ascender
- Clean off dirt, dust and debris after each use.
- Check the cam, teeth and moving parts for wear or damage.
- Lubricate the moving parts in accordance with the manufacturer’s recommendations.
- Store in a dry and clean place.
Anchor & Rigging Equipment
- Thoroughly inspect webbing slings, rope slings and anchor points before use.
- Replace any slings showing signs of wear, excessive UV exposure or chemical contamination.
- Document all inspections in the equipment log book.
- Rescue Equipment
Rescue Rope & Rigging
- Clean after every rescue operation — particularly if it has come into contact with mud, seawater or chemicals.
- Dry thoroughly before storing to prevent mould and fibre degradation.
- Store in a clean, dry rope bag, ready for deployment at any time.
- Carry out load tests and regular inspections in accordance with the team’s standard operating procedures (SOPs).
Rescue Hardware (Pulley, Prusik, Belay Device)
- Clean and inspect after each operational use.
- Ensure that all moving parts are functioning correctly and are free from debris.
- Replace immediately if any damage is found — do not use equipment whose condition is in doubt.
Helmet
- Clean with water and mild soap. Avoid chemical solvents.
- Check the shell, suspension system and chin strap regularly.
- Replace the helmet after it has sustained a significant impact, even if there is no visible external damage.
- Replace in accordance with the manufacturer’s recommendations (generally 5–10 years from the date of manufacture).
- General Principles of Care
- Always follow the manufacturer’s guidelines — each product has different care specifications.
- Discard equipment that has exceeded its service life, appears damaged, or has been subjected to extreme loads.
- Do not modify the equipment in any way.
- Store it correctly — away from UV light, heat, chemicals and excessive moisture.
- If you are unsure about the condition of the equipment, do not use it and consult us.

Description
Descender with integrated progress-capture pulley for loads up to 250 kg, compatible with 10.5 to 11.5 mm ropes
The MAESTRO S is a descender designed for technical rescue operations. It makes it easier to manipulate heavy loads when lowering or hauling and can be used in both the primary system or in a backup belay. This versatility allows rescuers to adapt to a variety of different situations they may encounter on the rescue scene. The ergonomic handle and integrated brake enable a comfortably controlled descent. Changing from lowering to hauling is immediate, without the need to transfer the load. The integrated progress-capture pulley has a large diameter sheave mounted on sealed ball bearings, providing excellent hauling efficiency. The AUTO-LOCK system automatically locks the rope when the handle is not in use. Once locked, the rope can be taken up without having to manipulate the handle. The MAESTRO S descender is compatible with 10.5 to 11.5 mm ropes and can handle loads up to 250 kg.
Description
- Great versatility, ideal for technical rescue:
- The locking system with integrated progress-capture pulley allows the same device to be used for lowering and hauling
- Can be used in both a single or twin primary system and in a backup belay (more information on this technique in the Instructions for Use and technical tips at www.petzl.com)
- Lower connection point can be used to create different types of haul systems
- Hole in the handle for installing a remote control cord
- Easy to use:
- Markings on the device make rope installation easy
- Ergonomic handle allows the rope to be released progressively and enables comfortable control of the descent
- Changing from lowering to hauling is immediate, without the need to transfer the load
- The AUTO-LOCK system allows the rope to be blocked automatically when the handle is not in use; once locked, the rope can be taken up without having to manipulate the handle
- Efficient for handling heavy loads:
- Integrated progress-capture pulley with very large diameter sheave mounted on sealed ball bearings; rotates in only one direction for excellent hauling efficiency
- Faceted sheave creates additional friction zones for the rope and provides additional braking when lowering
- Integrated brake on the device to adjust the friction based on the load and the rope diameter
- Compatible with 10.5 to 11.5 mm ropes for handling loads up to 250 kg Other Usage Characteristics:
- Can be used with a 10 mm rope for a working load limit up to 150 kg
