Maintenance schedule
WHEN
WHAT
ACTION
After commissioning
Spindle
The cylinder is furnished completely lubricated.
If the cylinder was held on stock at your premises
for more than 1 year, it must be relubricated
before commissioning.
see lubricating intervals and amount of lubricant
(see page 36)
Depending on the mileage,
see table Lubricating intervals
and amount of lubricant (see
page 36)
Leas screw
Relubricating the screw.

(see page 36)
Annually
Electro Cylinder
Visual inspection for external damages of the
actuator.
If externally caused damages are visible on the
thrust rod or on the profile, please contact
Parker.
Annually
Fixings provided by
the customer
Check screw tightening torque.
see mounting tightening torques ETH (see page
Annually, or every 6000 hours of
operation
Toothed belt
(with parallel
configuration)
In general, the high performance toothed belts
used in the ETH are maintenance free.
Visual inspection of the timing belt is however
required. Please check the toothed belt for the
following aspects:
Wear at the teeth
Cracks in the tooth root surface
Fractures in the belt back
If you find signs of wear, the toothed belt must be
exchanged (see page 40).
3.2
Lubricating intervals and amount of lubricant
The lubrication intervals depend on the operating conditions (series, pitch, speed,
acceleration, loads, etc.) and the ambient conditions (e.g. temperature). Ambient
influences such as high loads, impacts and vibrations shorten the lubrication
intervals. In short-stroke applications, a lubrication run must be performed after
max. 10 000 movement cycles. In the event of small loads and if the application is
impact and vibration free, the lubrication intervals can be increased.
Under normal operating conditions, the given lubrication intervals apply. If the total
travel per year is shorter than the given intervals, the cylinder must be relubricated
at least once per year. Lubrication is always required if the cylinder will not be used
for a longer period of time or when operation is interrupted! The lubricant used is
supplied by Klüber, it is available worldwide.
