
Pull the protection hose over the cable from
behind and fix it with the locking bolt.
ATTENTION!
Always use the guide hose. It acts as a vibration-
damping guide for the cable, as a dirt holder and
guard, also as a safety element for the operating
personnel and prevents uncontrolled banging!

Select an appropriate auger and securely
connect it to the cable with the snap-lock.

To release the snap-lock after cleaning, insert
the coupling key into the hole. The coupling
key is included in the scope of delivery.

Then pull the snap-lock apart with two hands.
NOTE!
If necessary, spray the snap-lock with a commer-
cially available rust solvent.
