When my G0453Z 15" planer arrived I discovered the 4" dust port comes out straight over the front of the outfeed table. When I attach my flexible hose it slumps over the center of the outfeed table making it impossible to run stock through without someone or something support the hose above the table. Just a really poor design IMO. Here's the kicker: The owner's manual that came with my machine shows a headstock breakdown on page 49, including a dust port that clearly angles 45 degrees off center, which would allow the DC hose to fall off to the side of the outfeed table. This is the proper design and is similar to what Jet provides on their 15" planer. I called Grizzly tech support and they could not explain why the manual shows a 45 degree angled port while my machine arrived with a straight port.
I'm heading up to my local Woodcraft store tomorrow to look for a 45 elbo that I can use to get the DC hose out of the way.
