Aidan, I am not familiar with using the ARRI but here is what I do on my Bell and Howell.
1. Before loading the film I reach the dry old gears with the spray nozzle of WD-40 lubricant and give a quick spray, then roll the gears a bit.
2. I use sensible (not full) spring tension. The crank can stay in the winder.
3. The trigger tapping mechanism is deluxe, a solenoid, a number 6 dry cell (or rechargable) cell, and a telegraph key.
4. Set up your ¨matte box¨ (lens bellows) nicely. No use making amateur quality pictures.
