Before and after each use, check the saw's safety mechanisms. Make sure that blade guards are operating properly and smoothly. Pay special attention to the proper care and storage of saw blades. Keep them clean and free of all dirt and resins. Oven cleaner does a great job.
Set the fan on your central air conditioner to “on” rather than “auto.” This will circulate air continuously, keeping the temperature more even throughout the house and aiding in dehumidification.
