Don't try to use a barbell that is too heavy or too long for you. Always consider your height and strength level when choosing the right barbell.
The pointed or pointed end of a large crowbar can cause significant material damage if used irresponsibly. Don't start using the big crowbar until you're sure what you want to do and where you want to do it.
Work at a slow and steady pace. This is especially important when breaking through heavy materials; Overvoltage too quickly will cause the overall job to take longer.
Bars should not be used for extremely heavy work. Know the limitations of your tool or you risk bending or breaking it.
