OPERATION MANUAL
5.2 MAINTENANCE
The following maintenance intervals are based on an 8-hour working day. If the specified number of operating
hours is exceeded during the corresponding period (e.g. due to shift work), shorten the period accordingly.
Info!
During the first six months of operation after commissioning and after major repairs, all parts of the device
must be checked more frequently.
HYDRAULICS
The entire hydraulic installation must be checked regularly for leaks.
Leaks can only be detected and located if the hydraulic system is cleaned regularly.
An oil change must be performed every 75,000 preassemblies (see absolute counter diagram, p.24) or
after two years at the latest. Use branded oil according to ISO VG 32 (HLP 32).
Hydraulic hoses must be checked regularly for damage.
According to DIN 20 066 for assessing functional capability, the period of use of a hose assembly, including
any storage period, must not exceed six years. The storage period should not exceed two years. The hoses
must therefore be replaced at intervals of four years.
ELEKTRICAL SYSTEM
Before starting work, check the electrical connection cable and electrical command devices for damage
every day. Damaged components must be replaced immediately.
Carry out the prescribed electrical tests in accordance with the applicable national regulations.
FUNCTION
When using a pre-assembly attachment with automatic tool recognition, the calibration must be checked
monthly.
To do this, insert counterholding plates of different sizes and check whether the display shows the correct
preassembly pressure by pressing the return stroke key. (comparison with pressure tables).
The calibration of the device itself and the checking of the shut-off accuracy can only be carried out by the
manufacturer. As a rule, the device should be checked every two years.
