Noticed that your fluid tank is clear rather than the black plastic that came with my unit. Also noticed the round pads on the arms; mine are square and larger.
After you get used to using it, you might want to think about hanging the pump assembly on the front wall and get some hose extensions that would allow you to keep the lines attached. You could run the hoses upwards along the two posts to the ceiling and then to the front wall and down to the pump. No tripping hazard that way!
Enjoy the lift, I really like mine!
