1. Coupling (clamp)
So that this modification can be identified in
conjunction with future developments in attachment
tools and KombiTools, as well as in the supply of
spare parts, the coupling with clamp 1127 162 3000
has been given the new part number
4137 160 2001.
1.1 Interchangeability
The previous and new clamps and couplings can be
interchanged as desired.

markets made it necessary to use the clamp
1127 162 3000 instead of the previous clamp
1121 162 3000.
To standardize parts, the clamp 1127 162 3000 is
now generally also used on all other model series
with series 4137 powerhead. The modification will
be introduced in the relevant series from the serial
numbers specified in the Summary.

2. Loop handle without barrier bar
For some time, the loop handle without barrier bar
has been supplied with two washers (2) which are
placed under the head of the screws (1) when
mounting the handle (3). This prevents the handle
being damaged by the locking teeth.
Service note
Place washers under the screws (1) if necessary
during repairs.

A screw with locking teeth must always be fitted
with a washer at this position on the handle.
5.2 Note for older machines
The new screw without locking teeth and fitted
washer can also be used on all previous versions of
the handles.
A screw without locking teeth has for some time
been used to secure the handle instead of the screw
(1) with locking teeth and washer (2). The washer is
consequently no longer needed.
