The first step is determining where on the shield you want to install the Taker R40.
The R40 comes with a drilling template that will aid in precise placing drill holes on the shield.
Measure the total width of the shield.
Then find the center point of the shield and mark with a marker.
Cut the top and bottom off of the template.
Position the template in the desired position on the shield, taking care that it is centered and straight.
Tape down the template to the shield taking care not to cover the drill holes with the tape.
Using a 1/8" drill bit, drill two pilot holes that are 50mm apart. Use the smallest circle as a guide to drill the pilot hole.
Then use the recommended 12/64" or 7mm drill bit and drill two holes using the pilot holes as guides.
Remove the tape and template from the shield.
You may see some frays in the holes from the drill bit. Pull those off and clean up the holes.
Use a utility knife to cut out any frays stuck to the shield.
Slide the included washers onto the bolts and then insert the 2 bolts into the front side of the shield.
The tab is designed to block refracted light from the back side of the shield. Depending on where the light is installed on the shield, position the R40 so that the tab faces the operator's eyes.
Holding the bolts in place from the front side, slide the R40 onto the bolts.
Now thread the nuts onto the bolts by hand.
Once tightened by hand, you can use a crescent wrench and Philips head screwdriver to tighten the bolts completely.
Be careful not to over tighten the bolts as it will push out the rubber adaptor shroud.
With that, your Taker R40 should be properly and securely mounted.
