INTRODUCTION
This manual shows the maintenance of the Lechler tank cleaning nozzle XactClean® HP+.
Please note: The Lechler assembly tool (order no. 05S.590.16.00.00.0) is additionally
required for maintenance 3.
The assembly tool can be reused. The spare parts package is required only once per
maintenance.
Depending on the operating conditions, we recommend dierent maintenance intervals
(maintenance 1 - 3). At each maintenance interval, a visual inspection of the parts must
always be carried out for wear and tear. We recommend replacing the O-rings each time a
sealing point is opened.
Note: Use suitable lubricant for EPDM O-rings.

too much torque is applied via the spray head, the pin deforms and protects thereby
the gear unit from damage. If the pin has been deformed, it must be replaced.
