motor by pressing the S button for about 10 seconds, until 
the 0 on the left in the display goes off. This only needs to be 
done if the motor reacts to other remote controls, or if the 
remote has been stolen or lost.

TIPS AND ADVICE

•  Do not overtension the chain, it must be stretched but not 

too tight.

•   Installation is easier if done by two persons, especially the 

installation of the rail in the roof.

•   A rubber strip should be fitted to the bottom edge of the 

door for optimum closing without the risk of the door going 
up again after closing. Program the bottom position of the 
door so that the rubber strip just rests on the floor. Note that 
ice, snow and debris under the door can still cause it to go 
up again if it cannot reach the set position.

•   Before installing the door opener, check that the door is in 

good condition and correctly adjusted. The springs have an 
optimum tension if the door can be released in half open 
position without it going up or going down. The easier it is 
to lift the door, the less the motor and other parts will be 
exposed to wear and tear.

MANUAL OPENING

The door can be opened manually in the event of a power failure. 
Pull the red line that is fastened to the runner on the rail and 
move the door to release the runner and the door from the chain.

To reconnect the chain to the door for normal use, lift or lower 
the door until it feels as if the runner has locked in the chain. Tug 
in both directions to check that they have locked together.

     NOTE:    
We recommend installing an emergency trigger if there is no 
other entrance to the garage than the door. This is a wire that 
fastens in the red line with a lock cylinder in the other end, 
which is fastened to the door. This means the line can be pulled 
from the outside with a key (HardHead art. no. 377014).
