Observe the regulations for handling solvents.
>Dry all parts aer cleaning.
3.5 Notes on pressing in sha seals
>Sha seals should only be fitted using a special press‑fit mandrel.
>When pressing in, pressure must only be applied to the outer ring
of the sha seal.
>When pressing in rotary sha seals using a press‑in mandrel, care
must be taken to ensure that the mandrel can exit unhindered on
the underside of the seal ring.

Maintenance
4 Maintenance
In the event of oil leakage from the pump (oil dripping from the
bottom of the housing), it is oen suicient to replace only the
replacement sleeve or the oil reservoir seal. The pump oil does
not have to be drained for this.
Dismantle the separator and the exhaust filter, if present,
before servicing.
During maintenance, all seals / O‑rings should always be
replaced.
Maintenance kit RE 8/9 - RZ 9/16: 20649988
Check the overpressure valve (accessory) at the oil reservoir
during maintenance, if an overpressure valve is installed.
Checking the overpressure valve ist described in the
instructions for use of the overpressure valve.
