10. Tests
The hydraulic power units are subject to very high levels of stress. A visual inspection must
therefore be carried out after every use and at least one visual inspection must be carried out
every six months. This reveals signs of wear in good time and punctual replacement of these
wear parts prevents damage to the equipment. Also check regularly that all the securing
screws are tightened (if applicable, comply with prescribed tightening torques).
Every three years or if there is any doubt regarding the safety or reliability of the equipment, a
functional test must also be performed. (Please also observe the relevant valid national and
international regulations pertaining to service intervals of hydraulic equipment). Operating
time per day In the Federal Republic of Germany, regular safety inspections according to
the regulations of the Gesetzlichen Unfallversicherung (GUV; connoted ‘Legal accident
insurance’) are mandatory.
ATTENTION!
Clean off any dirt before checking the equipment!
WARNING / CAUTION / ATTENTION!
To perform inspection, maintenance and repairs, personal safety equipment
appropriate for the work is an absolute requirement (if necessary also use
screening).
10.1 Recommended test intervals
10.1.1 Visual inspection
A visual inspection must be carried out after every use, but at least once every six months.
Operating time per day Functional test
up to 1 hour 1 x annually
up to 8 hours 1 x per quarter
up to 24 hours 1 x per month
In addition to these test intervals you need to carry out a function test if:
- the unit makes unusual noises,
- there is a justifi ed suspicion of internal damage to the unit.
If the noises and suspicions referred to above arise several times in a month, or if the
maximum pressure cannot be achieved during the function test, you need to contact LUKAS
customer service immediately. The contact details are given in the Chapter "Fault analysis".
