MSA Cairns 1010/1044 manufactured after March 2014 are marked with the Bourke mounting
hole locations.
(1) Select and cut out the template (see page 9) that matches your helmet model. Fold the respective
tabs toward you and align templates as shown in figure 1 and 2. Mark the mounting hole locations
according to your helmet model, using a spring loaded center punch or standard center punch. A
punch is not needed on new 1010/1044 helmet models, where the dimples mark the location for
drilling.
Note: Be careful not to move the template when marking the locations.

(2) Drill two holes through the marked locations with a 3/16" drill bit and clear away debris in and around
the holes.
(3) Open unattached lenses by grasping the lenses (as shown in figure 3 A) and press downward.
Rotate the lenses from the brass plate until they meet (as shown in figure 3 B) and are at a 90 degree
angle to the plate.
(4) Using the hardware provided, mount the Bourke to the helmet as shown in figure 4.
(5) Remove protective covering from the lenses.
Note: Be sure that the nylon locking portion of the nut fully engages the threads of the screw.
