Balance adjustement :
For a perfect balance of mechanism, you may have to adjust it as required
since not all mattresses have the same weight. Use a 17mm (or 11/16'') wrench.
Do it slowly half turn at a time, equally on both sides. To obtain a perfect balance,
the bed must be stationary in each opened position.
Do not unscrew completely the adjustement bolts. That may result
in severe damage to the bed and injuries to people may occur.
