7Operation

Warning

Make sure that in the travel range of the drive

– Nobody can reach into the path of the movable

components (e.g. by providing a protective

guard).

– There are no foreign objects (e.g. hexagon

wrench when setting the end position under

pressure).

It must not be possible to touch the drive until

the moveable mass has come to a complete rest.

8 Maintenance and care

Cleaning:

• Exha ust the DGSL.

• Clean the DGSL only with petroleum ether.

• Lubricate the following c omponents of the DGS L:

Component

Ungreased surfaces of

the piston rod

Roller bearing of the

slide

Lubrication inter val As required (e.g. after cleaning), otherwise the DGSL is

maintenance-free

Reason for lubrication Humidity protection and

gliding quality

Gliding quality

Lubricating point Piston rod Guide rail

Lubricating procedure Push the slide backwards and forwards by hand when

lubricating (even distribution of grease)

• Check to see if more frequent lubrication is r equired. This may be the case with:

– High temperat ures

– strong accumulation of dirt

– fat solvent fluids or vapours in the vicinity.

• Check the cushioning components 1 every 2 million cycles for signs of wear

(e.g. abrasion, oil leakage, ...).

• Replace the cushioning elements if there are signs of wear, at the latest after

every 5 million cycles (keep clamping component in a safe place when dismant-

ling the DGSL).

9 Repair and disassembly

• Exhaust the c omplete system and the device.

• Recommendation: Send the product to our repair service.

This way, the fine tuning and tests that are required will be taken into particular

consideration.

Note

In particular, attempting to repair the slide guide yourself is strongly discour-

aged.

• Information about spare par ts and aids can be found at:

www.festo.com/spareparts.

To replace the integrated cushioning components 1:

• Observe the section “Precision adjustment of the

end positions” in the chapter “Commissioning”.

Fig. 28

Proceed as follows:

1. Loosen the clamping component aE on the cushioning component (clamping

component can fall out).

2. Replace cushioning component ( Accessories at www.festo.com/catalogue).

Uneven movement of the

moving mass

One-way flow control valve not

installed correctly

Check the flow control

functions (supply or exhaust

air flow control)

Bearing surfaces dir ty Clean the bearing surfaces

tion

Speed too h igh Reduce speed

no or too low cushioning – Adjust shock absorber/

– Check and, if necessary, re-

place cushioning compon-
