1.
The hydraulic fluid level should always be near the top mark
when the machine is switched off. During production, the oil
level may drop after several consumers have been connected.
Check oil level at the oil sight glass.
2. Visual inspection of the hydraulic fluid. The hydraulic fluid may not exhibit any
foaming or cloudiness at the oil sight glass. In case of problems of this kind,
immediately determine the cause and correct the error. If in doubt, take a
sample for analysis and contact the manufacturer of the hydraulic fluid.
3. Check pressure setting on pressure gauge and adjust if necessary. The value
to be checked here is specified (see hydraulic diagram) and should be between
70-80 bar.
4. Check supply and fluid lines (damage and leakage). Supply and fluid lines must
be checked for damage. Pre-damage such as kinks or abrasions should be
logged and replacement should be initiated.
