Instruction Manual w Junior II
• Ensure safe and environmentally friendly disposal of con­
sumables and old parts.
2.3.5. Particular areas of danger
• Use only original fuses with specified current rating. If
there is a failure in the electric energy supply, shut the unit
down immediately.
• Work on electric units or operating equipment may only
be carried out by a qualified electrician or by a person
under the instruction and supervision of a qualified elec­
trician according to electric technical regulations.
• Machines and unit parts which must undergo inspection,
maintenance and repairwork, must be disconnected
from the mains supply, if specified. Parts which have been
disconnected must first be checked for voltage, then
earthed and short-circuited and isolated from live neigh­
bouring parts.
• The electrical equipment of a unit must be regularly
checked. Defects, such as loose screw connections or
burnt wires, must be rectified immediately.
• If work is to be carried out on live parts, work with a sec­
ond person who can operate the emergency off switch or
the main switch in the case of an emergency. Close off the
work area with a red and white safety chain and a warn­
ing sign. Only use voltage isolated tools.
• Only personnel with particular knowledge and experi­
ence with pneumatics may carry out work on pneumatic
equipment.
• Check all pressure lines, hoses and screw connections
regularly for leaks and visible damage. Immediately repair
any damage. Escaping air under pressure can cause injury
and fire.
• Depressurize system and pressure lines before commenc­
ing repairwork.
• Pressurized air lines must be laid and mounted by quali­
fied personnel. Connections must not be mixed up. Fit­
tings, length and quality of the piping must correspond to
requirements.
• Soundproofing equipment on the unit must be in place
and functional during operation.
• The stipulated hearing protectors must be worn.
• With regard to oil, grease and other chemical substances,
observe the relevant safety regulations for the product.
• For loading, only use lifting device and equipment with
sufficient lifting power and strength.
• Use only suitable transporters with sufficient carrying
power. Secure the load properly. Use suitable fixing
points.
• If necessary, provide unit with transportation brackets.
Display the appropriate notice. Remove transportation
brackets in the correct manner before taking into oper­
ation.
• Parts which need to be dismantled for transport purposes
must be carefully replaced and secured before taking into
operation.
• Even when moving the unit only slightly, the unit must be
disconnected from all external energy sources. Before
putting into use again, reconnect the machine to the
mains according to regulations.
• When taking back into operation, proceed according to
the instruction manual.
2.3.6. Notices of danger regarding pressure vessels
• Never open or loosen pressure vessel lids or pipe connec­
tion parts under pressure; always depressurise the vessel
or the unit.
• Never exceed the permissible operating pressure of the
vessels!
• Never heat the vessels or any of their parts above the
stated, maximum operating pressure.
• Always exchange damaged pressure vessels completely.
Individual parts that are subject to pressure loads cannot
be purchased as spare parts, since the vessels are tested
as a complete part and the documentation considers
them as a whole (see pressure vessel documentation,
serial-numbers!).
• Always pay attention to the permissible operating mode
of the pressure vessels.
We differentiate:
- vessels for static load
- vessels for dynamic load
Vessels for static load:
These pressure vessels are permanently under virtually
constant operating pressure; the fluctuations of pressure
are very small.
Vessels for this type of load are not marked in a particular
way and may be used as long as the vessel inspections,
carried out regularly, do not uncover any safety-relevant
deficiencies.
We recommend that aluminium vessels should be
exchanged after 15 years at the latest.
Vessels for dynamic load:
These pressure vessels may also be used under conditions
of changing operating pressure. The pressure may vary
between the atmospheric and the maximum admissible
operating pressure.
The pressure vessel documentation and the appropriate
notes in the operating manual particularly characterise
vessels of this type as being adequate for dynamic loads.
In the technical information for these vessels you will find
specifications concerning their permissible operating
period.
Due to the variation of the operating pressure, these
vessels are subject to a so-called dynamic load, which
puts the vessels under great stress. The change between
two different pressures is called a load change or cycle. In
the technical information for these vessels you will find
specifications concerning the permissible number of
cycles depending on the fluctuation of the operating
pressure.
Having reached half the permissible number of cycles, the
vessel has to be submitted to an internal check, in which
