Operating manual
6.3.3. Changing the nozzle
1. Loosen the fastening screws on the underside, remove the nozzle and dispose of it
2. Put on the new nozzle and fix it with the fastening screws
If there is hardened adhesive in the feed channel and inside the nozzle base, it
must be removed manually. Liquid adhesive does not need to be removed.
6.3.4. Substrate condition
The substrate must in general be even, dry, clean, free from cracks and physically sound.
The surface should also be slightly textured. Thoroughly vacuum off loose material and dust.
If applicable, it must meet the requirements of local standards or codes of practice.
7. Maintenance and cleaning
7.1. Maintenance
The Bona OptiSpread UX is maintenance-free if used properly and carefully in accordance
with the user manual.
7.2. Cleaning
The Bona OptiSpread UX is factory fitted with a PTFE working piston. The use of any
lubricants, fats, oils or similar is not permitted. If necessary, clean the inside of the tube only
with compressed air or a clean, lint-free cotton cloth or Bona Cleaning Wipes.
The upper part of the filling tube and the outer thread tend to be exposed to the most
contamination from fresh adhesive, which can get onto the thread and the inside of the filling
tube in very small quantities when the tubular bag is changed. This fresh adhesive soiling
should be removed immediately with Bona Cleaning Wipes, as adhesive build-up on the
threads or the inside of the pipe can lead to unwanted adhesive leakage.
Regular cleaning of the affected parts of the machine guarantees a long-lasting function of
the Bona OptiSpread UX and even less cleaning effort after you have finished your work!
