4. REPAIRS
Perform lockout/tagout procedures before adjusting, lubricating, cleaning
or otherwise servicing. Failure to do so could result in unexpected startup and could
cause serious injury or death.

glasses when working with snap rings and spring loaded retainers as they can be
ejected with great force. Use extreme caution and keep your body and face out of
the way.
