The lifting table must be serviced by authorised personnel only.
A visual and functional inspection must be carried out by a qualified person at regular intervals.
The inspection should include firm seating of screwed connections, fissures, deformities, cracks, damage,
wear, corrosion damage and operational faults of the product.
In addition, in the event of damage or particular incidents that could influence load capacity, and after repairs,
an additional inspection by a qualified employee of the operator is to be carried out.
The inspections are to be documented (§11 BSV).
The moving components must be checked regularly for ease of movement and if required relubricated with
commercially-available lubricating grease.
A daily visual inspection must be carried out to establish whether there are leaks in the hydraulic system.
Removing air bubbles
Lower the table and leave the lowering pedal (2) pressed down. Operate the lifting pedal (1) once more.
Topping up the fluid
To top up use a hydraulic fluid meeting ISO VG 46.
Lower the table. Remove the bleed screw (5) and fill fluid up to the lower edge of the fluid hole.
