Compression Check: Specifications

COMPRESSION CHECK
- The minimum compression in any 1 cylinder should not be less than 70 percent of the highest cylinder.
- No cylinder should read less than 690 kPa (100 psi).
- For example, if the highest pressure in any 1 cylinder is 1 035 kPa (150 psi), the lowest allowable pressure for any other cylinder would be 725 kPa (105 psi). (1 035 x 70% = 725) (150 x 70% = 105).
