On the upper level the Mobile Guard is used as a permanent guardrail by adding a
knee rail in the hooked in on the vertical arms of the Mobile Guard and mounted on
the second rungs.
During disassembly of the scaffolding above mentioned has to be done in reversed
order.
ATTENTION:
When you disassemble the knee rail can be taken out whilst sitting in the open hatch
as follows:
1 (if needed) remount Mobile Guards with knee rails on the second rung
2 unlock the braces at the longest distance from the hatch and lift them slightly by
rotating the closest vertical tube with hook in the direction of the hatch side of the
platform, the hook lifts and supports the horizontal guardrail
3 sit down in the opened hatch and unlock and take out the knee rails
