Stopping for Maintenance
WARNING
The following procedures should be followed when stopping the compressor for
maintenance or service:
Step
1)
Per O. S.H.A. regulation 1910.147: The Control of Hazardous
Energy Source (Lockout/Tagout), disconnect and lockout the main
power source. Display a sign in clear view at the main power switch
stating that the compressor is being serviced.
!
Never assume a compressor is safe to work on just because it is not
operating. It could restart at any time.
Step 2)
Step 3)
Step 4)
Step 5)
Step 6)
Isolate the compressor from the compressed air supply by closing
a manual shutoff valve upstream and downstream from the com-
pressor. Display a sign in clear view at the shutoff valve stating
that the compressor is being serviced.
Lock open a pressure relief valve within the pressurized system to
allow the system to be completely de-pressurized. NEVER remove
a plug to relieve the pressure!
Shut off the water cooling supply (watercooled versions).
Open all manual drain valves within the area to be serviced.
Wait for the unit to cool before starting to service. (Temperatures
of 125°F can burn skin. Some surface temperatures exceed 350°F
when the compressor is operating.)
Maintenance Schedule
To assure maximum performance and service life of your compressor, a routine
maintenance schedule should be developed. A sample schedule has been
included here to help you to develop a maintenance schedule designed for your
particular application.
Time frames may need to be shortened in harsher
environments.
The envelope shipped with the compressor contains a Maintenance
Schedule Checklist. Make copies of this checklist and retain the master to
make more copies as needed. On a copy of the checklist, enter dates and initials
in the appropriate spaces. Keep the checklist and this Instruction Manual
readily available near the compressor.
