1. Check that the rotor stops completely.

2. If your centrifuge is equipped with a three wire cord, turn off the POWER switch of the centrifuge and

turn off the distribution board of your centrifuge room.

If your centrifuge is equipped with a power cord with a plug, turn off the POWER switch of the centrifuge
and unplug the power cord from the receptacle.

3. Remove the two screws from the lower portion of the front cover with the cross-headed screwdriver.

Remove the four bolts from the front cover with the hexagonal key (accessory). Remove the front cover
by pulling the front cover.

Insert the hexagonal bar (accessory) into the hole for releasing the door lock (see below) and turn

the hexagonal bar 180 degrees to align the match-marks.

Fig. 3-4 Opening the Door

5. Release the door handle and open the door slowly.

Check that the rotor stops completely. If the rotor is rotating, close the door immediately.

WARNING:

In the event where the door is opened while the rotor is still rotating, close the door

immediately.

WARNING:

Never attempt to slow or stop the rotor by hand.

6. Take out the rotor. Reinstall the front cover (reverse the removal procedure). Then secure the front

cover with the screws.
