Door closer installation and maintenance
In-line door closer
Step 1: Before the door frame and the fan are in place, the bottom line should be smashed at the top of the door leaf and the door frame.
Step 2: Then embed the hydraulic buffer spring in the slot before installing the door and window, and screw the slide into the slot of the starter frame.
Step 3: After the door frame and the fan are fixed and fixed, fix the link to the spring shaft with a nut.
Exterior door closer
Step 1: The door closer can only be installed on the upper part of the door leaf near the hinge side. There is no end of the speed adjustment screw on the body. It faces the hinge. The four parts are used to fix the body on the door leaf, and then the lever is placed on the upper end of the pinion. The other end Install the cap and tighten the fastening screws.
Step 2: Secure the connecting rod to the door frame with two screws. The hand-held link is at right angles to the upper door frame. Loosen the lock nut and adjust the connecting rod to the appropriate length. Place the washer and tighten with a semi-circular head screw. Lock nut, installation is complete.
Step 3: The door closing speed has been adjusted. If you need to change the speed, turn the speed adjusting screw as shown.
Step 1: Install the top shaft on the door frame. The top shaft sleeve is mounted on the top of the door leaf. The center of the two must be aligned.
Step 2: Lift a plumb line from the center of the top shaft to the ground to find the centerline position of the bottom shaft installed on the floor and the position of the floor screw holes. Then remove the top shaft.
Step 3: First install the door spring body (referring to the frame bottom plate, etc.) in the lower part of the door leaf, then place the door leaf into the door frame, align the center of the top and bottom shafts and the position of the screw holes on the bottom plate.
Step 4: Then fix the top shaft to the door frame separately. The bottom plate is fixed on the floor of the building, and the floor and the floor should be flush.
Step 5: Finally, attach the frame cover of the spring-loaded main body to the door leaf.
Floor spring (floor door closer)
Step 1: First fix the top bushing plate on the upper part of the door leaf, then install the rotating shaft bar on the bottom of the door leaf, and install the screws on both sides. The center of the shaft hole of the top bushing plate and the center of the shaft hole of the rotary shaft must be aligned up and down, on the same center line, and perpendicular to the bottom surface of the door leaf.
Step 2: Install the top shaft on the top of the door frame. Pay attention to the distance between the center of the top shaft and the side column when installing. The door should be opened and closed flexibly.
Step 3: When installing, first hang a vertical line from the center of the top shaft to the ground and align it with the center of the ground shaft on the base. At the same time, the base level should be kept so that the gap between the upper panel of the base and the bottom of the door leaf is 15mm, and then the outer casing is filled with concrete, but the inner casing cannot be poured.
Step 4: After the concrete curing period is over, the shaft hole of the rotating shaft on the door and window is placed on the ground shaft of the base, and then the shaft hole of the top bushing plate of the door leaf is aligned with the top shaft on the door frame, and the top shaft is screwed. The lifting screw on the top allows the top shaft to be inserted into the shaft hole by 15mm, and the door leaf can be opened and closed.
Door closer maintenance
When the newly installed door closer is in use for a week or so, all the screws should be checked for tightness. The door closer should be inspected regularly after being put into use. The contents of the inspection are: whether the mounting screws are loose or missing, whether the connecting arm rubs against the door or the door frame, whether the door body is deformed or loosened, the buffering effect of closing the door, and the support guiding Whether the piece leaks oil, etc.
