If the chain hoist does not lift the test load or if the measured value deviates from the maximum load capacity, the friction clutch must be readjusted.

   Remove the sealing plugs. A slight amount of oil may thereby run out.

   Hoist motor, gear unit and chain may not move when adjusting the friction clutch. Block the chain in the chain guide or use the slip force test unit to block the chain.

   Set the friction clutch to 1.3 to 1.4 times the maximum load capacity. Turning to the right causes the friction clutch to engage at higher loads, turning to the left causes it to engage at lower loads.

   Check the friction clutch; see page 32.

If the friction clutch can no longer be readjusted, it must be exchanged. For this, contact ABUS Service. See page 89.
