MAINTENANCE

WA R N I N G

Always wear eye protection when lubricating or performing maintenance on the Starter Relay Valve. Always bleed off the air pressure before lubricating or performing any mainte- nance on the Starter Relay Valve.

Lubrication

Periodically lubricate the Starter Relay Valve as follows:

1.Bleed off the air pressure.

2.Disconnect the No. 4 Hose from the tank at the control air supply port near the bottom of the Starter Relay Valve oppo- site the air inlet. In some installations, this ¼" N.P.T. will be plugged.

3.Remove the plug. Squirt approximately 1 ounce (30 cc) of 10W oil into the Starter Relay Valve through the hose plug opening.

4.Reconnect the hose or reinstall the plug.
