Thus, the parts diagram should be used alongside the Hilti TE 22 service manual.

Symptoms: Motor runs, chuck rotates, but no hammering.
Diagram used: TE 22 exploded view (Rev. 4).
Procedure:

Outcome: Diagram reduced misassembly errors and missing parts.

Knowledge of the Hilti TE 22 and its parts diagram directly contributes to work efficiency in several ways:

In the parts diagram, the housing is usually the first layer. The TE 22 features a two-piece glass-fiber reinforced polyamide housing.

How this works: The housing is not just a shell. It channels cooling air over the motor and provides the structural rigidity needed to transfer impact energy from the hammer mechanism to the drill bit.
