threads, string...) from brushes and
axles.

stones, branches, ...).
8.4 Spraying the brush drives
with lubricant

cal.

amount of Haaga lubricant spray onto
the brush drives through the opening in

• Do not use naked flames or burners to
heat the bristles!

Bent bristles can be straightened again
by heating with a hot-air blower.
