how toremove line cover on mcculloch electrolux TM250 petrol strimmer?

this is a flat top, dome shaped plastic cover, with arrow showing direction to turn in order to remove for access to fit new line. I am unable to unscrew this cover, can you help please? is there a special tool.

i HAD THE SAME PROBLEM, JUST TURN THE COVER AS FAR AS IT WILL GO IN THE DIRECTION OF THE ARROW TILL IT STOPS THEN GENTLY LEVER IT OFF,USE A SPOON HANDLE OR SOMETHING SIMILAR, IT SHOULD THEN LIFT OFF. TRY A SPRAY OF WD40 OR SOME OTHER LUBRICANT THIS SHOULD HELP.

Make sure you lubricate the thread when you reassemble. I have this strimmer and after winter storage the head was impossible to remove without destroying the plastic.
