CHAPTER 4
Maintenance and Troubleshooting
Periodic maintenance
Periodic maintenance is service to be performed on the
equipment at regular intervals, designed to help minimize
unscheduled production down time and premature parts
failure. Flow recommends that you keep detailed service
records to help you prepare a maintenance schedule
that is compatible with your application and production
requirements.
Maintenance tips
The following tips could help avoid unscheduled
downtime.
•
Stock enough spare parts to get you through unsche
-
duled shutdowns and reduce the need to order parts
on a rush basis.
•
Practice good housekeeping in the work area.
•
Assign a complete set of service tools to the
workstation.
Maintenance precautions
•
Do not lubricate the motor excessively or too
frequently.
•
Protect all machined and lapped mating surfaces
against nicks, scratches, and burrs.
•
Carefully clean and blow out all parts being reassem
-
bled. Do not use paper towels or create airborne
dust.
•
Do not use any substitutes for the fluids, sealants,
and lubricants recommended by Flow.
•
Clean off grease fittings before connecting grease
gun to avoid injecting dirt-filled grease into the
bearings.
•
Correctly lubricate new bearings before operation.
General precautions
Observe the following general precautions at all times.
Review the safety information in Chapter 2 before per-
forming any maintenance or service. Do not make any
unauthorized changes to equipment or components.
Electrical
•
Maintain all electrical components, protective
guards, and shutdown devices according to
approved practices.
•
Make sure power cannot be applied to equipment
during maintenance work.
•
Before servicing, use a volt meter to make sure the
system is not energized. Take extra precautions when
servicing the electrical system in a damp environment.
•
Never use jumper wires across fuses, fuse holders, or
breakers.
•
Do not use metal rulers, flashlights, pencils, or tools
that have exposed conducting material.
•
De-energize all equipment before connecting or
disconnecting meters or test leads.
•
When connecting the volt meter to terminals for
measurement, use a range higher than the expected
voltage.
