(yellow/blue) do not act regulary through while
lifting/lowering and are interrupted, check as

Remove cover panel. Check continuity of the
two switches, on- and off- impulses of switches

switches move freely. Rollers and rams on
switches should move freely. If necessary, clean
and lubricate with a light machine oil.
