Weekly Checks
!
Close the air lockout valve and release system air pressure. Open filter drain cock to
release trapped moisture and other foreign matter.

!
Drain accumulated moisture from all air tanks.
!
Drain accumulated moisture from bottom of counterbalance cylinder.

Check for air leakage from valves. With main drive motor turned OFF and flywheel
stopped, energize clutch solenoid valve by actuating INCH buttons. While valve is held
energized, have another person check it for leakage.
WARNING: Clutch will engage when clutch valve in energized.
!
Make certain all solenoid valves are operating properly and that their response is
immediate and snappy. Replace the complete solenoid valve if it is worn or working
improperly.
Monthly Checks
!
Check accuracy and condition of air pressure gauges.
!
With air pressure turned on, check air lines for leaks and mashed sections. Also check
for broken or loose supporting hardware. Replace all hoses, tubing, and fittings that are
worn or damaged.
!
Check operation of regulators. With air pressure turned on, turn regulator adjustment
knob clockwise and note whether associated gauge reading increases. Then turn
adjustment screw counterclockwise and actuate the related component, or momentar-
ily open air lockout valve. Gauge should now indicate a lower reading. Replace a worn
or improperly operating regulator with a new one.

Check operation of air pressure switches by reducing air pressure to a point below the
preset operating range. Pressure switch must prevent normal press operation under
this condition.
