R18IW7 impact wrench "type-II" explain this please?

[rgormey]

I have two cordless tools
Ryobi impact wrench model number R18IW7
But what i have noticed is that on the impact unit with the later date stamp (2019) it has the words "TYPE II" on the ID plate.

model dated 2019 "type II"
model dated 2018 nothing

 

Can anyone please tell me what the difference is in regards to the reference to the "type II" wording

 

so..... whats the difference?  what does the "type-II" mean?

 

thanks kindly...

DeWalt does this as well, and I'm fairly certain the "type" simply denotes a small change in materials or design.

or design.

i`m curious to know what if any design changes are?

cosmetic?

motor speed/output?

Nm output?
