WARNING!
Risk of injury due to electric fault currents

and disconnect all connection phases are properly
installed.
– Ensure that the operator network has the required level
of protection.
WARNING!
Hazard due to missing or incorrectly assembled safety
equipment
Missing or incorrectly assembled safety equipment can
result in serious injuries.
– During maintenance work, safety equipment may only be
removed and re-assembled by trained and authorised
personnel.
– Before recommissioning after maintenance, assemble all
covers, unions and safety equipment in line with the
specifications.
– After assembly, check the function of covers, unions and
safety equipment.
Before starting any maintenance work:
n Turn off the Sauer-Compressor power supply and secure against being
turned on again.
n Put up “Attention! Maintenance work!” sign on the power supply.
n Mark the cylinders and cylinder heads to ensure they are in the same
installation position when assembled.
During maintenance work:
n All gaskets and sealing rings that are touched, exposed or removed
during maintenance work must be replaced and disposed of in an envi-
ronmentally friendly manner.
n Clean all exposed sealing surfaces.
n For unions, lubricate the threads with Innotec Ceramic Grease assembly
paste.
n Tighten unions with no specified tightening torques as follows:
– Tighten the union until there is a perceptible increase in force, then
mark the position of the union.
– Securely tighten the union by a further 30° (use the marking as a
guide).
