CARE AND MAINTENANCE
Before starting work on the pump,
make sure that the pump is isolated
from the power supply and cannot
be energized.
This applies to the control circuit
as well.
NOTE for Ex version page 3.
Make sure that the pump cannot
roll or fall over and injure people
or damage property.
The following points are important in connection with
work on the pump:
— Make sure that the pump has been thoroughly
cleaned.
— Beware of the risk of infection.
— Follow local safety regulations.
The pump is designed for use in liquids which can be
hazardous to health. In order to prevent injury to the
eyes and skin, observe the following points when
working on the pump:
— Always wear goggles and rubber gloves.
— Rinse the pump thoroughly with clean water before
starting work.
— Rinse the components in water after dismantling.
— The oil housing may be under pressure. Hold a rag
over the oil screw (oil plug) to prevent splatter.
Proceed as follows if hazardous chemicals have
splashed into your eyes:
— Rinse your eyes immediately in running water
for 15 minutes. Hold your eyelids apart with your
fingers.
— Contact an eye specialist.
On your skin:
— Remove contaminated clothes.

Inspection
Regular inspection and preventive maintenance
ensure more reliable operation.
The pump should be inspected at least once a year,
but more frequently under severe operating
conditions.
Under normal operating conditions, the pump should
have a major overhaul in a service shop at least every
third year for permanent installation and every year for
portable pumps. This requires special tools and should
be done by an authorized service shop.
If the seals have been replaced an inspection of the oil
is recommended after one week of operation.
NOTE! Regular check of the condition of the lifting
handle and chain is important.
Inspection of hot water applications
Pumps in hot water applications shall undergo
inspection or overhaul at a service shop as follows,
depending on the time they have been submerged in
the hot water:
