2. Operation of the viper

The viper 42 with 7 mm GRP rod is designed for professional chimney
sweeping. It permits to sweep chimneys of one- and two-family houses either
from above or below. The design-protected freewheeling clutch is a conveni-
ent feature of the viper.
Freewheeeling clutch
The viper is provided with a freewheeling clutch in which the braking action is
applied only on one side:
Easy running to the right (no braking action)
Hard or easy running to the left (braking action depends on the adjust-
ment)
This way, the GRP rod is controlled during winding/unwinding and cannot run
out of the viper.
The freewheeling clutch is adjusted with the star grip screw. Usually, only one
setting is sufficient, i. e. it is not necessary to change the clutch setting.
If you turn the adjusting screw clockwise, the braking action will increase (the
rod will not run out of the basket). If you turn it to the other direction, the bra-
king action will decrease and you can easily pull the rod out of the basket.
When pushing in the rod, make sure that it winds up smoothly over the entire
width of the basket. If the GRP rod winds up on one side only, it may jump
out of the basket.
Caution:
The conical interior section is designed in such a way that it brakes automati-
cally. For this reason you must release the braking force if the viper was not
used for some time. Release the force by turning the basket. .
