Decals, stickers and signs
Check that all the signs, warning decals and pictorials on the control centres are in place,

Product numbers of the decals are visible on the decals or the product numbers of new decal
sets can be found in the spare part list.

RK14)
• on the boom
• Limit switches for the chains (RK7 and RK15)

4.3.17.
Checking the operation of the safety limit switches
Check the operation of the safety limit switches for the outriggers and the boom from
the control centre UCB:
1. lift the platform from the transport position
• the outriggers must not operate in any position of the
selector switch
2. drive the boom to the transport position and lift the
outriggers
• the boom must not operate in any position of the
selector switch
3. lower the outriggers (level the lift)
4. put a load on the platform as shown in the picture:
260XTD: w = 80 kg
180XT II = 215 kg
100 mm
W
5. lift the boom and extend the telescope:
• The movement stops as soon as the red outreach limit signal light lights up (at max.
outreach). Now:
the lifting of the boom should be operational – the lowering of the boom must NOT
be operational
the retraction of the telescope should be operational – the extension of the
telescope must NOT be operational
