VIEW FROM WALL SIDE
CHAIN TENSIONER
The chain tensioner is to be fixed to the wall, or a bracket, by suitable bolts depending on the nature of the wall itself, and the
position is to be the most appropriate to allow installation and the subsequent adjustment of chain tension (the hexagonal head
to be on the side opposite the one facing MEC 200 LB).
• Loosen M18 nut to unlock the tensioner pinion.
• Adjust the position of the pinion as required by screwing or unscrewing the hexagonal head positioned on the side.
• Once satisfied the pinion is in the correct position for the chain to stay stretched, the M18 nut is to be locked back.
MOUNTING AND FASTENING MEC 200 LB
MEC 200 LB is to be mounted by positioning and fastening the motor base plate on to the previously fixed support bracket.
With the door in fully open position there must be a clearance of 10-15 cm as indicated in the picture, with reference to the
pinion.
