LEWI telescopic poles:
Ordering information
LEWI telescopic poles. Only genuine with the blue cone. LEWI telescopic poles are available in two to four pieces. Special sizes are available on request. All telescopic poles have a cone with the “fixed connection” and a clamping protection. Telescopic poles > 250 cm: Shipping only possible by forwarding agent.
The QLEEN principle:
Cleaning with pure water
The high chemical-free cleaning power of pure water is the principle on which the QLEEN system for glass and façade cleaning is based. Tap water is passed through a granulate bottle. The minerals contained in the tap water are deposited on the granulate. The tap water is demineralized and passes as pure water to the pump and from there to the cleaning head. Pure water not only has very good wetting properties, it also dries without leaving stains or streaks, even in bright sunshine. This means that in many cases there is no need to use cleaning agents (exception: greasy, oily or very heavy soiling).
Application note QLEEN:
Temperatures of the surfaces to be cleaned
It is dangerous to work at temperatures above 50 °C on the surfaces to be cleaned. Higher temperatures can lead to cracks or flaking on the surfaces.
Application note QLEEN:
Protection against frost
Unlike tap water, pure water (= demineralized water) already freezes at +1°C. The QLEEN system must therefore not be used at outside air temperatures below +3 °C. The QLEEN system must be protected from temperatures below +3 °C and frost, as frost can damage the water-bearing parts of the system.
Selection guide:
QLEEN pole systems
Basic application requirements:
- stiffer pole systems are particularly suitable for greater working heights
- the longer the work assignment, the lighter the pole system should be
QLEEN telescopic HYBRIDPOLE
Working height: up to 6 m (2nd floor)
QLEEN telescopic CARBONPOLE
Working height: up to 9 m (3rd floor)
QLEEN CARBONPOLE
Working height: up to 21 m (6th floor)
QLEEN TITANIUM POLE
Working height: up to 15 m (5th floor)
QLEEN Profi pole system
Working height: up to 21 m (6th floor)
Safety advice:
Avoid cleaning work on a ladder
- Always check whether it is safe to clean from the ground
- With QLEEN pole systems (with convenient and very stable bayonet lock) you can work safely at heights of up to 20 m, directly from the ground
- The LEWI safety cone (“the fixed LEWI connection”) allows you to work safely at all times, as the tools (LEWI tools) engage securely and cannot fall down
Safety advice:
Working at heights
Work at height is only permitted when wearing personal protective equipment (“PPE against falls from a height”). The regulations of occupational health and safety and the employers' liability insurance associations must be observed.
Safety advice:
Handling cleaning chemicals
Depending on the cleaning agent used, always wear the appropriate protective equipment (safety goggles, protective gloves, work clothing). The personal protective equipment depends on the product to be used and its labeling. Always observe:
- Optimum ventilation at the workplace
- Use cold water
- Dose cleaning chemicals correctly
- Never mix different products
- Only use cleaning agents approved by Lehmann KG for QLEEN and LEWI systems
