Before installation, please ensure that the following requirements are met:
1. Professional configuration of the device in line with its use
2. Installation of the device in line with the assembly and operational manual
3. Operation of the device in the scope of the approved conditions of use

Intended use
General use
AirScrape is a Contact Free Conveyor Belt Skirting system which hovers freely above
the conveyor belt, eliminating skirt friction and belt damage. Its unique array of
inward facing hardened steel diagonal blades, deflects larger particles inwards
while using the airflow of the conveyor belt and conveyed material to create an
inward suction, sucking or drawing any dust and fine particles back into the product
flow.
Component modification
Modifications of components and deviating configurations, installations, operations
and maintenance are subject to written approval of ScrapeTec. Failure to observe
these instructions could lead to increased risk of injury and damage.
Warning instructions
• During operation, unpredictable belt movements may occur, with a danger of
crushing. Owners must take appropriate safety measures (safety guards, warning
notice).
Safety measures during installation and maintenance work
• Installation and maintenance work on AirScrape blades must only be performed
when the conveyor belt is stationary and locked out. Cordon off the work area.
The work must be approved by the responsible works manager.
• Always use appropriate PPE.
• Always seek the owner’s permission if you need to perform welding or cutting (hot
work permits).
• If there is a risk of working at heights (working at heights permit) use of scaffolding,
railings, safety nets and harnesses and all other relevant safety equipment is
strongly advised.
• Before commissioning the Contact Free Conveyor Belt Skirting AirScrape, always
ensure that the work site is completely clear and parts, such as scaffolding, lifting
gear and tools are removed from the area. All guards have to be refitted to the
previous locations.
• Check that all screwed connections are securely tightened following any
commissioning and maintenance work.
• Use original parts only.

and repeat the procedure until
all the mounting points are
adjusted and the dome nuts
tightened up.
