ExTe TU - Insufficient Tensioning of Lashing; Tensioner Sluggish in Some Situations; Tensioner Jammed;Silent (when valve shut off); Tensioner Operating but Ratchet Does Not Get a Hold or Tighten

21
Problem Cause Solution
Insucient tensioning of
lashing
• Low air pressure • Make sure that the correct pressure is
supplied to TU. See “Recommended
working pressure” on page 7.
Adjust if necessary
• Ensure that air hoses and valves
are airtight. Fix any leaks
• The tensioner jams • Ensure that nothing (snow,
ice, mud etc.) is preventing the
movement of the TU’s shaft
• Ensure that drainage holes are
not clogged. If this is the case, the
inside of the tensioner may need
to be checked, which must be done
by a trained service technician
• TU is not greased; see page. 10
• TU is lubricated with the wrong
type of grease; see page 10
The tensioner is sluggish
in some situations
• Screws of the drum
tightened too hard
• Check torque on M8 screws holding drum
Noise in tensioner
(when valve shut o)
• Compressed
air not drained
through air valve
• Check the drainage in the air valve
Tensioner jammed/silent
(when valve shut o)
• Compressed air not
drained (via valve)
• Check the drainage in the air valve
Tensioner operating but
ratchet does not get a hold or
tighten
• Tensioner disengaged • Place disengaging lever in
operating position
Tensioner runs slowly • Low air ow to
tensioner
• Check the air hoses to the
tensioner to make sure no hose
is weighted/pressed together
Tensioning of sling too hard • Air pressure too high • Make sure that the correct pressure
is supplied to TU. See “Recommended
working pressure” on page 7.
Tensioner sluggish
(if bracket moved up)
• Bushing in bracket
loose/worn
• Replace bushing in bracket
