The paint is very chipped and can flake off by just touching it!

hey tony...
a small pressure washer capable of delivering 15-1800 pounds should be plenty - tip size is important also when pressure washing. the typical tip sizes are 40,25,15 & 0 degree tips...a 40 degree tip is similar in size to those used in self serve car washes - and that may be plenty for removing loose flaking paint. a 25 degree tip will put a little more force to the more stubborn areas without much fear of damaging the wood. a 15 degree tip is your chisel tip and should only be used on very difficult areas where paint is heaviest and adhering the tightest. a 0 degree tip, or an oscillating 0 degree tip, (or bullet point) should never be used on wood - it will damage the wood quickly.
if you're renting or buying a pressure washer for your job, the gpm is as important as the psi - a smaller, gas powered homeowner type of pressure washer may deliver 2-3 gallons of water per minute at 1500 pounds of pressure while a contractors model may deliver 7-8 gallons per minute at the same pressure (the homeowner electric models deliver approximately 1/2 - 1 gallon per minute and should probably be used only for car washes and light cleaning)...for the job you've described, the gas powered homeowner unit will work fine...
if you've never power washed before, it is a great way to prep a surface prior to painting or staining and will cut the prep time down considerably (and besides, they're kinda fun to operate)...if you use latex (acrylic) paint or stain as a finish, you'll need to wait only a day or so of warm weather before painting. and while pressure washing, be sure to wear rain gear and boots 'cause you will get wet...
good luck on your project and check out my previous post on how to finish wood fences.
