4 Safety regulations 

16 

Danger 

Safety measure required 

Risk of electric shock. 

Work on the electrical systems of the machine / installation may only be 
carried out by a trained electrician in accordance with electrical regulations. 
The system must be secured from being switched on. Seal off the main switch 
and remove the key and/or attach a warning sign to the main switch. 

Danger of electric shock from loaded condensers! Always first disconnect the 
system from the power supply and wait another 10 minutes before touching 
the electrical components. The power condensers require this time in order to 
discharge!  

The machine may start up 
unexpectedly. 

Only carry out maintenance and repair work when the system is not in 
operation and the power supply disconnected. Ensure that the power unit 
cannot be switched on inadvertently. The system must be secured from being 
switched on.   

Seal off the main switch and remove the key and/or attach a warning sign to 
the main switch.

 

Risk of injury from pressurized or 
moving parts. 

Only carry out inspection, maintenance, and repair work when the screw com-
pressor system is at a standstill and is not under pressure. The system must 
be secured from being switched on.

 

Before removing or opening pressurized components, positively isolate any 
source of pressure and depressurize the entire system. 

During the course of maintenance and 
repairs, parts can be damaged which 
are important for safety. 

Never weld any pressure reservoir or change it in any way.  

If work which produces heat, flames, or sparks has to be carried out on a 
machine, the adjacent components have to be protected by means of non-
inflammable material.  

Motor, air filter, electrical components, and regulating equipment have to 
protected from the ingress of humidity, e.g., when cleaning the system by 
means of a steam jet. 

Under no circumstances must the sound-proofing material be removed or 
modified. 

Never use etching solvents which could attack the materials used. 

Before cleaning the machine with water or steam jet (high-pressure cleaner) 
or other cleaning agents, cover/mask all openings which have to be protected 
from the ingress of water, steam or detergents for safety and/or functional 
reasons, in particular electric motors and switch cabinets. After cleaning, 
remove the covers/masking completely. 

Modifications to the machine impair 
safety. 

After completing repair work, always check to see whether any tools, loose 
parts or cloths have been left in or on the machine, driving engine or driving 
equipment. 

After the work has been completed, replace any protective devices that have 
been removed. Operation without protective devices is not permissible. 

Always re-tighten screwed connections which were loosened for maintenance 
and repair work.  

Machines performing rotating movements have to be cycled several times in 
order to ensure that there are no mechanical faults in the machine or the drive 
member. 

Before releasing the power unit for operation after maintenance or overhaul, 
check that the operating pressures, temperatures and time settings are 
correct and that the regulating and shutdown equipment function properly.
