I've got a Challenge DCSRT18 Strimmer ut have lost the operating instructions. The battery is fully charged but how do I turn the strimmer on? Is there a safety switch that I can't remember about - its been a year since I used this last. I can press the small button to release the trigger then pull the trigger, but nothing then happens (currently - please excuse the pun).

Can I get an operating manual online as well?
