Application / Behavior
Warning of crush hazards on a piece of equipment (e.g., a
machine) or structural components (e.g., covers, enclosures,
guards, fences) during transport.
Working at the labeled workstations requires increased
vigilance.
Do not go beneath a suspended load. The driver is not allowed
to drive the industrial truck if a person is located beneath the
load. The driver must also make sure that no one stands or
walks under the load.
The load must be transported so that it is sufficiently clear of the
ground (max. 20 in above the ground). The driver is responsible
for all travel and load movements of an industrial truck.
Labeling of lifting points.
Only the labeled lifting points may be used for transport.
Opening pressure of the pressure relief valve (for value "xx" see
the sticker on the control panel).
Warning of loosened clamp connections. Clamping pressure can
fade after some time.
Check the clamps regularly according to the safety guidelines and
tighten as needed.
Warning against dangerous electrical voltage.
Warning of stored energy in the form of capacitors. They carry
deadly electrical voltage.
Do not open the electrical switch cabinet (compressors with
variable speed drives) for 10 minutes after disconnecting the
compressor.
Work on the electrical equipment of the compressor may be done
only by an electrician in accordance with electrical rules.
Check the DC bus voltage at the system terminal strip of the
frequency converter by measuring this between the
+DC and -DC terminals (the exact position can be found in the
supplied operating manual of the frequency converter), between the
+DC terminal and the chassis as well as between the -DC terminal
and the chassis.
The voltage must read zero in the case of all three
measurements.
Warning of springs under tension in the interior of the intake
regulator.
Before opening the intake regulator, read the repair manual.
