3.3 Correct Blade Installation and Tensioning
For optimal cleaning efficiency and long wear life, the U-Type® blade must be located and tensioned correctly on
the belt. If the cleaner pole is in the wrong location the performance of the new blade may be adversely affected.
See “Possible Problems” below. For tensioning, please follow these instructions.
Correct Tensioning:
Correct tension is determined and set by blade width. Check the information provided with the tensioner being used
or consult the installation instructions.
Possible Problems:
• Pole location too low - The initial cleaning will be
concentrated in the center of the belt, failing to
clean the outer edges efficiently.
• Pole location too high - The intial cleaning will be
concentrated to the outer edges of the belt, failing
to efficiently clean the center of the belt.
• Tension too low - Without the optimal tension,
the cleaning efficiency is reduced and chatter or
bouncing of the blade can occur.
• Tension too high - Although the cleaning may
appear efficient, accelerated blade wear may
occur; and in some cases less efficiency on the
outer edges of the belt, which could result in
increased belt wear.
Correct Pole Location:
When the blade contacts the belt (before tensioning)
there should be blade-to-belt contact across the
entire blade (Fig. 1). If contact is more in the center
with a gap on the outer edges, the pole will need to
be raised until full contact is achieved (Fig. 2). If
contact is more on the outer edges with a gap in the
center, the pole will need to be lowered until full
contact is achieved (Fig. 3).
