We again from the perspective of its production to fastidious, floor spring worm gear structure makes the degree of compression spring degree is smaller than the door closers gear rack drive, plus close to spring arm too short, so the quality of the floor spring on the dependence of the structure design and processing precision is high.
In addition, because the door fan of two-way door opens to the floor spring with a large force, the service life of low floor spring and high grade spring is very different.

When the door is closed with the floor spring, it will be stuck in a position that cannot be moved.
if the rod has been broken or inserted into the cylinder pin and the rod screw falls, the spring should be replaced in time.

The two speed adjustable floor hinge guide head automatically rises.
the two speed adjustable floor hinge guide rod is not jammed or unstuck bearing position.

If the valve screws tighten (clockwise) when adjusting, it will slow down, which is to turn the two speed adjustable floor hinge power down.
If you turn the valve screw loose (counterclockwise), it will increase the speed, which is to increase the door closing force.
The adjustment must be controlled at a very small amplitude, and each adjustment will test whether the door fan is in the right direction. If the range is too large, the screw will be turned off, resulting in the leak of the door closer.
