1. Aluminum alloy doors and windows in use, action to light, push and pull along with its natural; find difficulties not hard push hard pull, should first exclude the failure. Ash accumulation, deformation is the main reason for the difficulty of pulling the doors and windows of aluminum alloy, to keep the door frame clean, especially the cleaning of push-pull groove. Vacuum cleaners can be used to absorb the ash accumulated in the trough and the door seal.
2. Clean aluminum doors and windows, people do not tread on the aluminum box, do not pull the frame to support.
