2.6 Mounting extension parts
- Loosen the clamping screws (6) on
the support tube. Then turn in the
center expanding screw (5) to expand
the clamping joint.
- Pull the telescopic tube out of the sup-
port tube (7).
- Mount the required extension parts.
m
Observe the guide groove of the spline!
Make sure that the shaft end is clean!
- Slide in the telescopic tube. When do-
ing so, make sure that the drive of the
auger gear is slid all the way over the
shaft end of the auger extension part
and that the threads of the augers
match.
- Remove the expansion screw (5). Then tighten the clamping screws (6). Finally
tighten the expansion screw by hand.
m
Before the clamping screws (6) can be tightened again, the expansion screw (5) must
be sufficiently turned back!
Otherwise, the telescopic tube cannot be safely clamped and the splined shaft ends
break.
f
When clamped insufficiently, the telescopic tube can slide out of the support tube.
Danger of accidents during transportation!
