UNDER NO CIRCUMSTANCES SHOULD THIS BE DONE BY HOLDING THE
TELESCOPES.
• If your Loupe Frames are fi tted with prescription lenses, you may fi nd it necessary to
position your Loupes on the front stop of the Loupe pins to prevent the telescope from
touching the lenses, particularly when the curvature of high-powered lenses prevent the
Loupes from being angled fully downward.
4.3 HOW TO FIT THE LOUPE ‘FLIP UP’ LEVER
Keeler Surgical Loupes are mounted on a specially designed hinge, permitting the telescopes to
be fl ipped up out of view when not required (Fig. 10).
To avoid touching the non-sterile Loupes, a sterilisable Loupe Flip Lever is provided with each
pair of Loupes (spares are also available). When magnifi cation is required again, the Loupes
may be returned to their original preset working angle. The Loupe Flip Lever is fi tted by pushing
onto the Loupe bar (Fig. 11) and removed by twisting off.
Over a period of time the hinge tension may slacken slightly and require adjustment. Using
a small crosshead or Phillips screwdriver, adjust the hinge screw to the required tension as
shown (Fig. 12).
