Do a preoperation inspection


Make sure that all warning decals are visible and legible.
Turn on the utilities
1. Turn ON the utility water to the pump.
2. Turn
ON
the compressed air source. Set the air pressure between 4.8 bar and 5.5 bar (70 psi
and 80 psi).
3. Turn
ON
the electrical main (line disconnect switch).
4. Turn the primary breaker disconnect lever on the electrical enclosure door to ON .
5. Make sure that the EMERGENCY STOP is not engaged. If the button is pushed in, turn the
button clockwise until it releases.
WARNING
Make sure that all connections, fasteners, locking devices, hoses, and fittings are tight.
CAUTION
A leak can cause damage to the water fittings.
Monitor for leaks during this procedure.
Identify the source of a leak and correct the problem.
CAUTION
Air pressure that is too low can prevent the bleed-down valve from closing and can
cause the intensifier to overstroke.
Air pressure that is too high can cause damage to the needle and the seat in the
bleed-down valve. If the available air pressure is too high, install an air regulator (not
included) to reduce the pressure.
