Received hw100, strange recommendation

For you hw100 owners, I see the manual recommends removing the air cylinder when not in use. Never heard of that on any other pcp. Do you guys remove your air cylinder? With all posts about leaking cylinders maybe all this on and off is the problem. Haven't had a chance to shoot for groups but I did run it on the chrony, not bad, 893 low and 903 high. Beautiful laminate stock with adustable cheek piece. It's my first in .177 caliber. Cant wait to shoot it for groups.

I have never posted a pic, but here goes my first try.
 
Lawyers first. Safety safety safety, ???
THE ONLY owners manual I have ever seen that speaks to the legality of Birds and the liability therein involved, yikes.
And do remember to replace that air cylynder at exactly 10 years ( maybe a better idea than removing the tube all the time.

Does seem a perversion of safety concerns, many mentions of not leaving cylynders in car, do wrap in foam, use climate control, eye wear, i.d. tags , supervision, required Govt. permits ......
Maybe
try around page 23.
