Operation
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.

Maintenance and care
Cleaning:
• Exhaust the DGSL.
• Clean the DGSL only with petroleum ether.
• Lubricate the following components of the DGSL:
Component
Ungreased surfaces of
the piston rod
Lubrication interval
As required (e.g. after cleaning), otherwise the DGSL is
maintenance-free
Reason for lubrication
Humidity protection and
gliding quality
Lubricating point
Piston rod
Lubricating procedure
Push the slide backwards and forwards by hand when
lubricating (even distribution of grease)

• Check to see if more frequent lubrication is required. This may be the case with:
– High temperatures
– 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).

Repair and disassembly
• Exhaust the complete 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 parts 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".
Proceed as follows:
1. Loosen the clamping component aE on the cushioning component (clamping
component can fall out).
2. Replace cushioning component (
