Officers say they feared for their safety while arresting Dale Burns, 27, who died two hours later after suffering a heart attack.
A bodybuilder was Tasered four times in under a minute by police as they struggled to arrest him, an inquest has heard.
Dale Burns, 27, from Barrow-in-Furness, Cumbria, died hours after being repeatedly hit "without warning" by the electric shock gun and pepper-sprayed in the face, as officers tried to hold him with handcuffs and leg restraints, the hearing was told.
Burns, as father of two, was described as a "gentle giant but with a drug habit" who had taken a "gram of Madcat", an illegal drug, on the day he died, the inquest at the County Hall in Kendal heard.
Alan Sharp, the deputy coroner for south and east Cumbria, told the jury of five women and six men they may have to see distressing CCTV footage of a wild-eyed and agitated Burns in the police van after his arrest for criminal damage.
Burns died at Furness General hospital two hours after police were first called to his flat on 16 August 2011.
