DISASSEMBLY OF SECOND STAGE

Proper torque for the hose fittings is 40 in. lbs. (4.5 Joules). NEVER tighten the hose
fitting to the first stage with more than 45 in. lbs. (5 Joules) of torque. The inlet hose
fitting can be weakened by overtightening. Failure of the fitting could cause air loss
resulting in death, personal injury or property damage.
