torque wrench

Hi guy's,

Next saterday i'm going to pick up a used (but never used??)torque wrench.
Some pointers on where to look at, faults or anything?
It's the kind with a click, not the one with a needle

It's a wrench from 280 to 760Nm, so when i have this one, it will be the
mother of all....;o))

Make sure the lock works. If not, you'll loose the desired setting
while torqueing. With the lock engaged, you should not be able to
change torque settings.

if it is a craftsman, go to your local store and swap the "old" one for
a brand new tool.

Cool! Always store it with the adjusting barrel completely loosened or
it will eventually lose its calibration.

Hey thanx for the info all...
Will keep it in mind next saterday!

Thanks again
Roger
