Opening Levers
After unscrewing and pulling out the pressure release plug, the lid can be opened. To overcome the
friction of opening, two levers are used to push against the lid with a cam action. On some models
these opening levers are bolted to the body. On the other models, they are detachable levers.
Important!
Be sure they are inserted all the way flat to the
housing before turning to avoid damaging the
protrusions on the lid.
The body has two holes on opposite corner edges of the housing for opening. Gently lever off the
lid with the supplied cams taking care not to twist the lid excessively. The lid should be opened
keeping it approximately parallel to the body at all times. If using a single lever, turn first one side a
little, then the other an equal amount, and repeat again until the lid is opened.
Remember
to
unscrew and pull out the pressure release plug all the way first, otherwise the air pressure will resist
attempts at opening. Lay the lid on a flat stable surface after opening.
