WARNING
Never dismount the cover, when the pump
hose is in the pump head. The compres-
sion forces on the pump hose are partially
compensated by the cover. By removing
the cover, the pump housing may become
deformed.
WARNING
Because of the heavy weight, use the
Cover Lifting Device (refer to
8.9.4 and
8.9.5 ) or suitable equipment to move the
cover.
