Clean with a soft, lint-free cloth and non-abrasive cleaning agents. Check the compatibility of the clean-

ing agent with the materials to be cleaned.

Thin grease lm outside

A lm of grease covers the external surface so that the grease colour tarnishes the surface slightly.

Recommendation:

Apply the grease with a soft brush or similar.

2.1 General safety instructions

Warning

Read and follow all safety instructions and information. Failure to comply with these safety instructions and informa-

tion can result in serious injuries.

Note

To achieve ATEX conformity, the toothed discs must be replaced each time the corresponding screws or bolts are loos-

ened. When screwing back in, observe the tightening torques given for the screws.

– The control block may only be repaired by authorised and trained personnel acting in accordance with the require-

ments in these repair instructions and the brief instructions for the device.

6 / 74 DFPDb_en

– Pay attention to cleanliness while repairing the quarter-turn actuator. Do not allow dirt particles to get into the quar-

ter-turn actuator.

– A shutdown must be performed before any repair work is carried out.

– Before repairing the quarter-turn actuator, any attachments on it must be dismantled.

– The control block must be completely depressurised and de-energised, and reliably secured against unauthorised

restarting before starting any repair work is started.

– Accidental switching on or concealed pressure can trigger unexpected movements during dismantling of the quar-

ter-turn actuator. Therefore, completely vent the quarter-turn actuator before each repair.

– Use original spare parts only to repair the quarter-turn actuator.

– Wear the necessary personal protective equipment.

– In the event of damage to the quarter-turn actuator caused by

– unauthorised manipulation,

– non-intended use (misuse),

– use of non-original spare parts

all warranty and liability claims against the manufacturer expire.

– The technical documentation required for installation and start-up (functional test) of the quarter-turn actuator must

be available.

2.2 General information

– Standard tools are needed to repair the quarter-turn actuator, which must be available in a service workshop

(Chapter 1.4 on page 6).

– Components and equipment replaced during repair must be disposed of in accordance with the relevant local

environmental protection regulations.

– Where possible the repair should be carried out on a stable and at work surface with space for small parts.

– The gures of the repair steps show size DFPD-300-…-D / S-…-60 (12 installed springs) by way of example. Individual

minor differences between the quarter-turn actuator in hand and the illustrated example are possible.

– Depending on the temperature range (standard / T4 /T6), Festo recommends the following lubricants:

– SYNTHY POLYMER 402/2 (standard variant)

– HEVOLIT PE 280-1 FG (high-temperature variant T4)

– RENOLIT SI 300 M (low-temperature variant T6)

– Individual components must be greased when installing the quarter-turn activator. The following table shows the

recommended quantity of grease during the entire installation.
