NOTE
The brake has no air gap adjustment. If the air gap exceeds 0.5 mm, the brake pad needs changing.

3.2.4 Load chain

The load chain should be periodically checked for abrasion. The check is based upon three measurements: see accepted wear factors (table 3-3)
and measurement points (figure 3-1).
CAUTION !
The chain should be replaced when the measurements exceed or fall short of those defined in the table. The chain wheel and chain
guide should be checked for wear at the same time and, where necessary, be replaced. Only use original chains. The chain links
should not be welded.
The new chain is installed in accordance with chapter 2.2.2.
NOTE
For ease of installation, the old chain and new chain can be connected by a piece of flexible wire.

3.2.5 Limit stop assembly

CAUTION !
A damaged buffer plate, underneath the housing, must be replaced.
Screw connections at the limit stop and shims or lower sheaves should be checked and, where necessary, tightened to the right torque. For
coefficient data see chapter 3.2.8.

3.2.7 Slip clutch

The slip clutch is set at 125% at the factory and can be relied on to prevent the chain hoist from being overloaded (the force limiting factor
according to DIN EN 14492-2 is
CAUTION !
Adjustment and testing of the slip clutch may only be carried out by authorized personnel and must be recorded in the log book.
