10.7 Replacement of valves

WARNING

Pressurized and energized system parts!

Danger to life! Risk of injury caused by electric shock!

▶ Ensure that the hydraulic system is depressurized and the electrical control de-

energized before disassembly.

CAUTION

Falling of not fully secured valves

Risk of injury!

▶ Secure valves to be disassembled against falling down.

Leaking hydraulic fluid!

Risk of injury! Risk of falling!

▶ After disassembly, seal the hydraulic fluid bores with suitable cap elements.

▶ Immediately remove leaked hydraulic fluid and dispose of it properly.

▶ Have sufficiently dimensioned collecting containers, residue-free industrial

wipes and hydraulic fluid binding materials ready in order to collect or bind
leaking hydraulic fluid.

Only use valves or safety-relevant components such as orifices listed in the
product-related parts list.
In determining the achievable category and performance level, certain fault
possibilities were excluded for the safety-relevant components. These fault
exclusions are dependent on important design features of the components used.
The safety-relevant components may only be replaced by components of the
same type.

Spare parts from stock that have not been filled or treated with corrosion
protection fluid may resinate. Clean them with grease solvent and build up
a new oil film.
