my Hitachi saw won't release

[john]

hard to push down and won't release back up unless I jerk it back up and it's really hard

[John Rumm]

Especially when you don't give even a hint of what saw you are talking about!

Jigsaw, chainsaw, cold sore? Model?

I have a friend who says she only needs two DIY items.

If it should move but doesn't, she uses WD40.

If it shouldn't move but does, she used Duct tape.

Oddly enough, one of our nuclear power stations had a problem like this last week, we recommended an initial treatment with WD40, and it worked a treat.

This was on a 100 ton jack which was potentially going to cost them something like £1m a day in lost output if it went badly.

A fairly well known thought - I call it gaffer tape - but I suspect it's pretty similar.

[newshound]

Seems like the OP had never heard it, though.

I think gaffer tape is easy peel - Dave Plowman probably knows.

[Dave Plowman (News)]

Dunno what you mean by easy peel. It's just a general purpose fabric backed sticky tape. With decent quality sticky.

[John Rumm]

Gaffer tape IME is usually a vinyl covered tape with a fabric re-inforced core, and then a very aggressive slightly rubbery adhesive. Strong, stick like the proverbial, but can also be torn relatively easily across or along the tape. Duct tape is similar but usually thinner and more flexible.
