"I only made one bogey so it was pretty solid," said the Swede.
"I hit a lot of greens. I think I only chipped three times in two rounds so I think that's the key.
"It's been a good start so I feel it's going to be a good experience to play tomorrow."
France's Jeong weon Ko carded another 66 to move into second place at 10-under ahead of home favourite Thomas Detry who also closed with a 66.
"Winning an event is great, winning your first event is even better and winning it at home would be just an absolute dream. I’m just going to try and enjoy it and we’ll see what happens," said Detry.
England's James Morrison carded a 69 for a share of third place at 8-under alongside France's Julien Brun (67) and Sweden's Jens Dantorp (69).
