you hear a louder metallic noise at the stop (the cushioning
is reduced).
b)
Turn the hydraulic shock absorber (
25
) slightly back into the
stop sleeve (
27
) to extend the cushioning stroke. This once
again creates a soft stop.
The cycle time has now been optimized.
3.
Tighten the lock nut of the hydraulic shock absorber (
26
) to fix
the set position.

Maintenance and repair
Cleaning the mini slide
No special servicing is required for the mini slide. Note the
following if you would like to clean the device:
After cleaning, you must apply lubrication grease to the surface of
the piston rod and the ball bearings of the slide.
O
Apply the following types of grease to the piston rod or the
guide rail. During greasing, move the slide slowly in both
directions manually to achieve an even distribution of the
grease.
W

– Stroke up to100 mm: Paralique P460
– Stroke from 125 mm: MICROLUBE GL 261
Maintaining the mini slide
Mini slides with elastic stops (versions EE, EM) are maintenance-
free.
O
Observe the system-specific maintenance intervals.
Lubricating the guide rail
It is recommended to grease the guide rail of the
MG
version mini
slides once a year (for the permissible grease see the section
“Cleaning the mini slide”).
Checking the seals
The seals of the mini slide may age faster under aggressive
ambient conditions. Defective seals will lead to pneumatic leaks.
1.
Check the seals regularly.
2.
Establish the maintenance intervals according to your ambient
conditions and enter them in the system-dependent
maintenance plan.
Exchanging the hydraulic shock absorbers
For mini slides with hydraulic cushioning, a maintenance interval
of 4-8 million cycles applies.
O
Replace hydraulic shock absorbers after 4-8 million cycles as
follows:
Shorter lubrication intervals are required in the case of:
W
High temperatures

NOTICE!
The bolt (

1.
Loosen the lock nut of the bolt (

).
2.
Set the position of the pneumatic cushioning to optimize the
cushioning effect. Proceed as follows:
a)
Begin with the full cushioning length (

=0 mm). For this
purpose, move the bolt (

) exactly to the edge of the sleeve
(

.
b)
Now reduce the cushioning length by turning the bolt (
22
) in
small steps back into the sleeve (

cushioning length until you reach the lowest stop.
The cushioning effect has now been optimized.
3.
Tighten the lock nut of the bolt (
