Maintenance and service 11.
The hydraulic units are subject to very high mechanical loads. A visual inspection is therefore
to be carried out after every use: however, at least one visual inspection is to be carried out
every six months.
This reveals wear and tear in good time; punctual replacement of these wearing parts
prevents damage to the equipment. Also check regularly that all the securing screws are
tightened (if applicable, comply with prescribed tightening torques)
Every 3 years or when there might be doubts regarding the safety or reliability of the unit, an
additional function check is to be carried out (in this connection, comply with the applicable
national and international regulations with regard to the maintenance intervals of rescue
equipment). In the Federal Republic of Germany, regular safety inspections according to the
regulations of the Gesetzliche Unfallversicherung (GUV; 'statutory accident insurance') are
mandatory.
CAUTION!
Clean off any dirt before checking the equipment!
WARNING / DANGER / CAUTION!
In order to carry out maintenance and repair work, tools appropriate for the job
and personal protection equipment obligatory (including protective covers).
LUKAS offers a suitable test kit for the function test of the hydraulic units.
(For specific details, please consult the LUKAS range of accessories or contact your
LUKAS dealer).
11.1 Recommended testing periods
11.1.1 Visual inspection
11.1.2 Function test
A visual inspection must be made after each use / latest once a year.
Operating time per day Function test
up to 1 hour
once per year
up to 8 hours once per 3 months
up to 24 hours once per month
Beyond these testing periods, a function test should be accomplished, if the aggregate
makes suspicious noises, or there is a reasonable suspicion of an internal damage of the
aggregate.
If the noises or suspicious factors named above should occur several times during one
month or the hydraulic unit does not reach the nominal pressure (75% of the maximum
pressure) during the functional test, you will have to contact the LUKAS customer service
immediately. You will find the contact information in the chapter 'Troubleshooting'.
