Never operate the pump if parts of the pump are dis-
assembled. Ensure that the pump cannot be operated
accidentally.
➨
Before starting maintenance, isolate the pump from its
application and disconnect the electrical power cord.
➨
Note: The pump or the pump oil might be contaminated
with dangerous or corrosive process chemicals that
have been pumped during operation. Adopt suitable
decontamination measures if necessary. Take ade-
quate precautions to protect people from the effects of
dangerous substances if contamination has occurred.
Ensure that the maintenance technician is familiar with
the safety procedures which relate to the products pro-
cessed by the pumping system.

Use appropriate protective clothing, safety goggles
and protective gloves. Avoid inhalation and skin con-
tact.
• Take adequate precautions when handling pump flu-
ids, lubricants, and solvents. Use appropriate protective
clothing, safety goggles and protective gloves to avoid
excessive contact with the skin and possible skin irrita-
tions (including dermatitis).
Comply with all relevant statutory requirements and
regulations concerning the handling, storage and dis-
posal of oil.
Aging of the oil (as indicated by darker color compared to
new oil, strange odor of the oil, particles in the oil, or con-
tamination) necessitates an oil change.
Depending on the application (especially if corrosive gas-
es or vapors have been pumped) it may be appropriate to
check the oil frequently and to carry out an oil change, if
necessary.
