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.
