Inspecting the inverted tooth chain

To ensure failure-free and safe operation of the inverted tooth
chain drive, the inspections listed in Table 10 must be carried out
at regular intervals.
The intervals depend on the system with which the inverted tooth
chain drive is used.
During the first 200–400 operating hours of the running-in phase,
the inverted tooth chain elongates more. Therefore, more frequent
inspections are necessary during the running-in phase.
Observation
No oil film is present on the
inverted tooth chain.
Wear and tear manifests in
irregular material removal or
planing.
The chain is slacking off.
The slack span is not within
the permitted range.
