level.
Always insert the rack as illustrated
above with the loading surface in the
lower position.
These accessories have non-tip safety
notches located towards the back of

notches prevent the accessories from
being pulled out completely from the
shelf runners when you only wish to pull
accessories out partially. They also
prevent accessories from tipping.
