CORRECTIVE ACTION

Poor performance and overheating of converter.

Step 1.

Check for air in system.

a. Low basic pressure, overheating and loss of pulling power are likely indications of air in

the system. Partially open the bleed valve at the high point of the fluid system with the

unit running. If any air is present, the source of the air leak into the fluid system must be

located.

b. Check the fluid level in the reserve tank to be sure it is not too low.

c. Make a very close check of all points on the suction line (D) from the reserve tank to the

charging pump. It may be possible an air leak exists in this line which may not show up as

a fluid leak with the unit shut down.

NOTE

To insure proper bleeding of the fluid system during operation, remove the orifice assembly (E)

and clean the filter screen and give particular attention to the orifice hole in the body of the

assembly.
