share a common principle

10. Pump problems
or system problems?
85% to 90% of "pump" problems
are actually systemic

28. Safety
1. Read all warning tags
2. Shut off main power
3. Follow proper lockout/tagout procedures
4. Observe caution and warning labels
5. Ensure that repair and maintenance are
performed ONLY by trained, authorized personnel
6. Always use a ground wire on tools and appliances
that are not double-insulated
