Information:
Each engine installation must be inspected in order to determine the most advantageous starting conditions. The setting of the pressure regulating valve is affected by the following factors:
Loads from attachments that are pulled by the engine during the start-up
Ambient temperature conditions
Viscosity of the lubricant for the air starting motor
Capacity of the air reservoir
Condition of the engineHigher pressures provide increased torque for the starting motor and faster rotation of the engine. Lower pressures prolong the supply of pressurized air.Use the following procedure to check and adjust the pressure regulating valve:
Purge the pressurized air from the system.

Pressure regulating valve
(1) Adjusting screw
(2) Regulator inlet
(3) Regulator outlet
Disconnect the air line from regulator outlet (3).
Connect an 8T-0849 Pressure Gauge to regulator outlet (3).
Apply air pressure to the gauge and check the pressure.
Use adjusting screw (1) to adjust the air pressure to 620 to 1030 kPa (90 to 150 psi).
After the pressure is correct, purge the pressurized air from the system.
Remove the 8T-0849 Pressure Gauge Group from the regulator outlet. Reconnect the air line.
