The equipment is subject to very high mechanical stresses. Therefore, a visual inspection
needs to be made after each use, at least once per month (if continually used, once per
week).
In this way, early signs of wear are recognisable so that damage to the device can be avoided
by prompt replacement of these worn parts. Also check regularly to make sure that all
attachment screws are tightened (observe any applicable tightening torque specifications).
At least once a year (if continually used, once every half year) or if there is a doubt about
the safety or reliability, a functional check should also be performed (for this purpose, also
heed the corresponding applicable national and international specifications related to the
maintenance intervals of the devices).
ATTENTION!
Clean the device before checking for dirt!
Do not use any aggressive agents for cleaning; it could cause damage to the
equipment.
Because LUKAS devices are designed for the highest performance, only
components may be replaced that are listed in the spare parts lists of the
corresponding device.
Additional components of the equipment may only be replaced if:
- You have participated in a corresponding LUKAS service training course.
- You have the express permission of LUKAS customer service (by
request, check on the grant of permission. A check is necessary in each
individual case).
10.2 Maintenance
Before performing maintenance work, clean the hand pump thoroughly.
After performing the maintenance work, you should carefully coat all metallic parts with oil
to prevent any corrosion.
Checks (Maintenance measures):
Perform a visual inspection of the hand pump at least once per month; in the case of
continuous use, once a week.
Visual inspection
Hand pump
• are all hydraulic connections still tightened,
• generally sealed, no leaks present (oil "sweat" has no effect on the operation),
• is damage to pump housings, valve blocks or attachment parts recognisable, especially
on the moving parts such as the piston rods,
• are all fluid levels within the prescribed tolerances,
• are all non-moving parts firmly attached,
• is there no corrosion,
• free movement of the pump lever, the locking mechanism and the hand wheels
(check in the depressurised state),
• the couplings are easy to couple (if attached),
• are dust caps in place,
• are identification plate, all control decals, instruction decals, labels and warnings present
and legible.
