..Over the years I know of half a dozen cases where compound bows have self destructed with force enough to knock over furniture...lol
most times these bows are in a closet or bow case under the bed and no one was anywhere near them...
Most are due to old and un maintainanced strings...
If your going to store a compound bow for anylentgh of time..a Q-tip dipped in olive oil or a speacialized odorless petroleum type gun oil on all metal bolts and screws...
...Most important is Wax and/or condition strings thouroughly ...Excess wax can be taken off by running dental floss on string after storage..
...Turn bow down in poundage as much as manufactuer suggest and store in bow case...
...add moisture absorbing packs inside case
....check periodically
If unsure of strings condition have strings replaced before storage...new strings are a lot cheaper than new cams ,axle, limbs, etc AND strings after
JMHO
