4.3 Handling the tension ratchet
Threading the belt
With the ratchet closed, quickly pull the locked function slide (1)
in order to move the ratchet lever (2). Thread the end of the belt
into an appropriate position in the slot shaft (3) and pull until the
belt is tensioned.
Tensioning the belt
By moving the ratchet lever, ratchet until the required, or maxi-
mum, belt tension is obtained. In doing this there must be at least
1.5 turns on the slot shaft.
Closing the ratchet
After this, pull the function slid and swing the ratchet lever into
the locking position until the slid is able to lock into the securing
groove.
Opening the ratchet
Before opening the ratchet it is imperative to ensure that the leak
sealing bag is not under pressure because when opening the rat-
chet, the belt is suddenly released.
When opening the ratchet, the function slid is to be pulled and
the ratchet lever is to be swung approximately 180° to the end
stop in order to let the slide lock into the last possible position.
The slot shaft is now no longer locked. The belt can now be un-
coiled and taken out.
