Assembly instructions
Before fitting, measure the distance from door leaf to ceiling. There must be a
minimum of 5 cm of clearance above the garage door for the garage door to
move through its entire range of motion.
If the distance is more than 14 cm, the garage door opener must be fitted
suspended from the ceiling using the fittings supplied.
If the distance to the ceiling is less than 5 cm, ask the retailer for advice.
Assembling the rail
Assemble the rail by fitting the 2 assembly sections around the middle section
of rail, and then attach the other rail sections. Fit the gearwheel with the chain
wrapped around it. Make sure the chain is straight in the rail and is not twisted.
Check that the fitting for the lock on the trolley is on the correct side of the
trolley.
Now tighten the chain using a 14 mm spanner on the nut at the opposite end of
the gearwheel. The chain must be tightened so that it cannot fall out of the rail.
Check that the chain is still fitted on the gearwheel. The sides of the chain must
not touch the bottom of the rail.
