NOTICE: Do not keep the shut-off valve closed more than 5 seconds or the pump could be damaged by over-heating.
11. Immediately open the shut-off valve fully. If the pump is in good condition, the gauge should read at least 7,940 - 8,630 kPa (81 - 88 kgf/cm,
1,150 - 1,250 psi). A low reading means pump output is too low for full assist. Repair or replace the pump.
