7.1.2 Lifting the Draw-out Switch
Proper lifting equipment must be used to
lift the draw-out switch for inspection
and servicing (Note: eg. the weight of
4-pole draw-out switch is 100kg / 220 lb).
A pull-out rod is used when lifting the
switch, see the Fig. 7.3 on next page.
If it is necessary to remove the switch
from the track mechanism, the fixing
screws must be unfasten, see the Fig. 7.2.
NOTE! When the switch is attached back
to the track mechanism, the fixing screws
have to fasten!
