5.2.3. Applying adhesive
Place the full Bona OptiSpread 100 Battery on the nozzle head, press the
starter and step back.
Starter
The amount of adhesive applied depends mainly on your speed of motion,
the nozzle size and the feed which can be adjusted continuously from
1-9
.
Note:
When squeezing from a new nozzle for the first time, it takes a little time
before the adhesive comes out of the openings.
If you let go of the starter, application of adhesive is stopped immediately.
The piston is slightly retracted (audible). Exact and dosed application of
adhesive is possible.
Tubular bag
If possible, try to ensure that the adhesive bag is completely emptied. If this
is not possible, the partially used tubular bag can remain in the machine for
up to 12 hours. The machine must be stored horizontally.
If work is interrupted for a longer period, the partially used bag should be
removed and closed using a cable tie. When required, this closed bag can
then be used again.
Depending on the age of the foil bag, gas pressure may develop inside the
bag which results in a swelling of the foil. This may make insertion more
difficult. We recommend that the foil be pricked with a needle close to the
clip. Surplus pressure can then escape. However, this has no effect on the
respective adhesive.
Nozzle
If work is interrupted for a longer period (up to 12 hours), adhesive which has
come out on the nozzle toothing will harden. We recommend that such
surplus adhesive be removed using Bona Tool Cleaner and that the outlets
be covered with adhesive tape.
In case of longer interruptions, the nozzle has to be cleaned or, if required,
replaced with a new one. Hardened adhesive must not be pressed out by
squeezing new adhesive behind it. This may cause damage to the drive or
serious fouling.
