Preparation before Surgery Preparation before Surgery
Checklist: Before the operation Cleaning the optical accessories ➩ Select the eyepieces, objective and the documentation accessories (if used) and check them for cleanliness. ➩Remove dust and dirt (see page 66). Checking accessories ➩ Lock the swing arm. ➩ Outfit the microscope with all accessories for use (see page 17 and page 18). ➩Turn the 0° assistant's attachment to the desired side (Leica M844, see pages 17 and 20) or install attachment for second observer on the desired side (Leica M820, see page 18). Balancing ➩ Loosen swing arm and balance it (for F40, C40, CT40 see page 27, for F20 see page 28). Function check ➩ Switch on the microscope. Warning Motors return to their home position ➩Before switching on the microscope, ensure that the travel paths of the X- and Y-axes and the focus motor are free of obstructions. ➩ Check the Main Light 1, Main Light 2, and OttoFlex™ II illuminators. Replace defective bulbs before the operation begins. ➩Footswitch/handswitch: Test all functions. ➩With handles and remote brake release, check the function of the brakes (for F40, C40, CT40 see page 27, for F20 see page 28). Positioning at the operating table ➩Position the surgical microscope at the operating table as desired and secure the brakes on the floor stand (see page 31). Checking the tube settings ➩ Check the tube and eyepiece setting for the selected user (see page 39). ➩Treat the eyepieces with an antifogging compound if necessary. Sterility ➩Fit sterile components and sterile drape if used (see page 32). Warning Danger of fatal electric shock! ➩Operate the system only with all equipment in its proper position (all covers fitted, doors closed).

Preparation before Surgery
Fitting optical accessories for Leica M844
Fitting the tube ➩Release the clamping screw on the dovetail ring of the 0° assistant’s attachment and remove the black protective cover. ➩ Carefully insert the second observer tube and tighten the clamping screw.
Warning Risk of injury from downward movement of surgical microscope! ➩ Complete all preparations and adjustments to the stand before the operation. ➩ Never change the accessories or attempt to rebalance the microscope while it is above the field of operation. ➩Before re-equipping, always lock the swing arm. ➩After re-equipping, always rebalance the microscope on the swing arm. ➩ Do not release brakes in an unbalanced state. ➩Before re-equipping during the operation, first swing the microscope away from the operating field. Take care that the articulation brakes are tightened and the swing arm is blocked before you mount accessories to your Leica M844 (see page 27). Installing the objectives ➩Tighten the objective to the microscope (right-hand threading).
Fitting eyepieces ➩ Affix the eyepieces with the fixing rings in the tubes. Fitting the Double Wing We recommend mounting the longer arm of the Double Wing on the side of the focus housing in order to achieve optimal ergonomic conditions. ➩Unscrew the clamping screw as far as necessary using a screwdriver. ➩ Insert the flange of the Double Wing into the dovetail ring so that the arrow is positioned directly above the clamping screw. ➩Hold the Double Wing firmly and tighten the clamping screw. We recommend that, for the main surgeon, the UltraLow™ III binocular tube be used in combination with the double wing. The UltraLow™ III binocular tube offers better ergonomic conditions.
Fitting the 0° assistant’s attachment The 0° assistant’s attachment must be directly attached to the optics carrier.
Clamping screw
➩Unscrew the clamping screw as far as necessary using a screwdriver. ➩ Insert the 0° assistant’s attachment into the dovetail ring. ➩Hold the 0° assistant's attachment in place and tighten the clamping screw. Do not use a beam splitter in addition to the 0° assistant’s attachment.
