performed by trained specialist personnel
only.
 Unsuitable mounting and handling of
hydroaccumulators can result in serious
accidents.
 Do not put damaged hydroaccumulators into
operation.
 Before working on a hydroaccumulator,
reduce the pressure in the hydraulic system
as described in these operating instructions.
 Do not weld or solder onto the
hydroaccumulator and do not perform any
mechanical work. The hydroaccumulator can
be damaged by the effects of heat and can
burst due to mechanical processing.
DANGER OF EXPLOSION!

the necessary pressure for the intended
purpose prior to putting the machine into
operation.
 Operating data (minimum and maximum
pressure) must be constantly indicated on
the hydroaccumulators. The indicator must
remain permanently visible.
