Modifications to Parts

Do not attempt to make any modifications or alterations to the device regarding the configuration, 
installation, operation and maintenance without written approval from 

HOSCH

. Unauthorised modifi-

cations or alterations to the device could lead to serious damage to property and personnel.

General Danger Notice

During operation, unexpected deflection movements may occur. Danger of entrapment exists. The site 
operator should guard the mountings (railings, danger signs, etc).
The wearing of scraper parts may cause sharp edges. The risk of injury during installation or 
maintenance exists.
Prevent the scraper from unintentional pivoting.
Due to the friction that occurs during operation, the blades or module tips are likely to become very 
hot. Touching them immediately upon stopping the belt can lead to serious burns.
The contact between the blades or modules and the running conveyor belt can create static electricity. 
Be cautious when touching the device! Attention: Sparking may occur through discharge. 
Mineral or metallic particles may collect on the belt surface and, in exceptional cases, cause sparking 
when passing the blades or modules.
The weakened structures of worn parts are likely to break. To guarantee personal and conveyor safety, 
these parts have to be replaced with new ones.

Safety precautions during installation and maintenance work

Carry out installation or maintenance work on the scrapers only after the conveyor belt has been 
stopped and "locked-out". The working area has to be isolated. Do not begin any work that has not 
been previously authorised by a responsible person.
Protective clothing, in particular safety boots, gloves, helmet and protective glasses are mandatory.
An authorised work permit from the relevant manager must be obtained prior to any welding and 
cutting work.
When working at heights, provide safety devices, for example scaffolds, railings, guard nets, safety 
harnesses. The devices must have been inspected and released as fit for work.
Prior to operating the scraper, ensure that the site is completely cleared. All equipment or parts, such 
as scaffolds, lifting gears, tools etc. should be removed from the area prior to restarting the conveyor 
belt. Safety devices (hoods, guards etc.) that may have been dismantled must be refitted.
All screwed connections are to be checked and secured before each stage of commissioning and after 
each service. Security components (spring washers, counter nuts) should not be re-used. They must be 
replaced with new parts. In case of mechanical damage, e.g. corrosion, new parts must be installed.
Only original, genuine 

HOSCH

 parts should be used.
