Drill the hole
Make the drill hole using Würth hollow drill bit, there is no need for hole cleaning
Clean the drill hole:
Blow out 2x with oil-free compressed air (min. 6 bar)/brush out 2x/blow out 2x with oil-free compressed air (min. 6 bar)
Cut anchor rod to length and mark the desired insertion depths
Screw mixer onto cartridge
Discard the first section of mortar (until the mortar is uniformly coloured - approx. 10 cm)
Fill injection mortar starting from base of drill hole
Press in anchor rod up to drill hole base while turning slightly
Visual check of mortar volume, embedment depth mark
Observe the injection mortar curing time
Install component, apply installation torque
