11 Disassembly and removal

WARNING

Danger of damage to property and personal injuries at pressurized or energized
system parts!

For works at pressurized or energized system parts, there is a danger of injury by
escaping hydraulic fluid or electric energy.

▶

Before disassembly, ensure that the hydraulic system is depressurized, and the
electrical control is de-energized.

Explosion hazard!

Disassembly of the valve cap or the connector will lead to loss of the explosion
protection!

▶

Never disassemble valve cap or connector.

CAUTION

Falling of an incompletely disassembled valve!

An incompletely disassembled valve may fall down and cause injuries.

▶

During disassembly, secure the valve against falling.
