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 poppet seat
in the bleed-down valve.
If the available air pressure is too high, install an air regulator (not included) to
reduce the pressure.
