Remove floorboard glue from mitre saw
It is really difficult to remove adhesive from plastics as they bind. You may have luck with the blade. 

For the blade, Heat and friction is probably your best bet. 

Heat up the cutting blade with a blow torch, then use a chisel or scraper to remove the softened adhesive. 

If that doesn't work you can use alcohol and scrape it off, but that could take a while. 

Just remember to be safe. Heated metal can leave nasty burns, and slipping whilst scraping can cause damage to your skin.
