STEP 5:
setting up the lens #3

Take the front element, remove the cover sheets and secure it to the lens body using the four cap screws. Before tightening the screws, attach all four screws so that they are still loosely held. Be careful not to overtighten the screws.

You slightly have to zoom in the picture after the front element installation. Also now adjust the changed focus from projector settings while the lens is at the 'IN' position to achieve the optimum sharpness.

In case the friction based lens height (a) or the tilt (b) adjusting mechanism become too loose, it is possible to get them tightened with the set screws of stand drums on both sides of the lens. Use the L-wrench for tightening the screws.
