Mounting the tripod

1. Check the pick-up (dia. 4.5 mm) to ensure that the components
(clamping sleeve (5), marker ring (7) and suction insert with heat
shield (10)) are correctly seated.
2. Screw tripod (4) to pick-up (6) with the aid of clamping sleeve (5).
You can use the pick-up (dia. 4.5 mm) mounted in this way with a
small reflow nozzle (A) or without a reflow nozzle (B). When working
without a reflow nozzle, you can also use a 10 mm dia. pick-up.

3 steps:
