I have the same product. I thought there was a problem with reverse, can only pull trigger a bit and goes slow. I checked with their support and this is normal though no mention in instructions. I tried a few different makes in B and Q and some have similar restriction in reverse. I think this is a feature of these types of ‘pneumatic’ type drills. It might damage pump ifgoes fast. Slow reverse just for extracting if gets stuck.
