Nussbaum TC 410 Manual De Instrucciones página 30

The bead breaker arm of the TC 410 has 2 working positions (see Fig. G/1 and
G/2):
- the position shown in Fig. G/1 is recommended for working on wheels with rims
up to 10" wide;
- the position shown in Fig. G/2 is recommended for working on wheels with rims
more than 10" wide;
The angle of incidence of the bead breaker blade varies depending on the position
chosen.
To change from one working position to the other, proceed as follows:
- extract the peg (1).
- turn the blade by hand until the hole on the hub is in the other position;
- fit the peg (1) in the new position.
N.B.: The blade angle can also be increased by moving the rod to the right, for
easier bead breaking on small-diameter rims
WARNING: NEVER break the bead of rims less than 6" wide
with the bead breaker arm in the "+10" working position.
The optional stroke limiter (see Fig. G/3) is required for bead breaking on RUN
FLAT, LOW PROFILE and UHP tyres.
The device limits the "closure" of the bead breaker by different amounts depending
on the position of the pin (1, Fig. G/3):
- setting "0" : no limitations
- settings 6"-7" ; 8 -9" ; 10"-11" : indicate the rim width for which the bead
breaker closure is set.
Check the width of the rim then place the pin in the correct hole: the stroke limiter
will allow the bead to be broken without letting the shovel penetrate too far and
crush the beads (see Fig. G/4).
