charge to the control valve. Check truck manual for the exact loca-
tion.

• Remove and clean the control valve.
Discharge Valves
Are Difficult to
Operate. Lack of lubrication. • Recommended weekly lubrication of discharge and suction valve.
• Use a good grade petroleum based silicone grease.
• Foe Hale Products, SVS Valves, etc., use Never-Seez® White
Food Grade with PTFE.
• Refer to separate valve manual for addition information.
Valve in need of more
clearance for opera-
tion. • Multi-gasket design allows additional gaskets fro more clearance
and free operation.
Note: Adding too many gaskets to the valve eventually causes
leakage.
