The manual says not to use the standard 13mm chuck with the SDS drill
when in hammer mode. What is the actual problem with doing this? A
standard chuck can cope with basic hammer drills - is it the heavier
force from the SDS drill that could be a problem?

If it's like my DeWalt, it wouldn't work anyway - the chuck shaft isn't as
long as a drill and won't make contact with the mechanism.
