Dean, see you found a real nice one. I have a bunch of info on these things that I will gather up and forward you. Start here at a free link to to a downloadable Operators Manual, TM-9-2359-272-10. Just tried to download it and it still works. Link is

BV 206 is the link the above one came off of. Appears to be a Hagglunds website. Good info here. I need to find the Hagglunds email address I have that I sent my serial number to requesting any info they may have on my unit. They responded back with exact manufacture date and where it was delivered to off the assembly line. Mine, Dec 21, 1988 and it was delivered to the Norweigan Defense Forces. How it got here they did not know. They also sent US contact info who was an office in Maryland. Anyways I'll see what I can round up. Someone really put a nice interior in yours. The military versions are very sparce inside. No padding like yours. Check the interior pics shown here. They are a blast. Stay off gravel roads and away from small rocks. They really wear down the drive sprockets and can chip the rubber on the road wheels and even tear a track if the rocks get in the wrong spot. And watch side ways on hills in the snow. They tend to slide sideways and get stuck believe it or not. They slide off the packed down track you leave and bottom out (high center). Had to use my deuce to pull mine out. Was driving it in the deep snow right off a paved road. You can take any angle hill straight on like you wouldn't believe. Low range it and it will pretty much go straight up. In low range it will pull a buried Explorer (greeen one) out like it was hard pavement.
