Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a bad
weld, report it to your supervisor.
Hoses and Fluid Lines. Look for wear, damage, and leaks, and make sure clamps and fittings are tight.
Wet spots show leaks, but a stain around a fitting or connector can also mean a leak. If a leak comes
from a loose fitting of connector, tighten it. If something is broken or worn out, report it to your
Special Instructions. Preventive maintenance is not limited to performing only those checks and services
listed in the PMCS table. Stowing unused accessories and other routine procedures such as equipment
inventory, cleaning components, and touch-up painting are not listed in the table. These are things you
should do any time you see that they need to be done. If equipment must be kept in continuous operation,
check and service only those items that can be checked and serviced without disturbing operation. Make
complete checks and services when hypochlorination unit can be shut down.
