D.  Vacuum new fluid into the sump cleaner. 
E.  As soon as fluid stops passing through  
 

the hose, stop the engine by turning the 

IGNITION switch OFF. Close the gas bottle  

valve. This valve must always be closed  

when engine is not running. 

The tank’s maximum capacity is, at most, 10% 
above the rated capacity. A float switch in the 
tank and wired into the engine ignition circuit 
will shut down the engine if overfilling starts 
to occur. If this happens, place the IGNITION 
switch in the OFF position, and close the  
gas bottle valve. Follow instructions for the  
discharge operation in Paragraph 10.

8.  To discharge clean fluid:

 close the suction 

inlet ball valve V1, attach the 1-½" hose to the 
discharge port on the clean side of the unit. 
Move the 4-way valve control lever to the  
vertical (DISCHARGE) position. Open the  
gas bottle valve and press the electric primer 
button for at least two seconds. Turn the  
IGNITION KEY SWITCH ON. Depress the  
discharge hose nozzle valve.

A.  THE SUCTION/DISCHARGE lever must  
 

be turned its full quarter turn to the vertical  

(DISCHARGE) position in order to close a  

limit switch beneath the lever (FIGURE II-F). 

This limit switch bypasses the float switch  

needed to prevent overfilling during the  

suction operation, but is not required for  

discharge operation. The engine won’t start  

in the discharge mode if sump cleaner tank  

is full and the limit switch is not closed.

B.  Be sure the suction inlet ball valve V1  
 

is fully closed before operating in the  

discharge mode!

C.  IMPORTANT! Be sure the suction inlet  
 

ball valve V1 is fully closed or fully open,  

depending on the desired operation (closed- 

discharge, open-suction). Failure to do so  

will allow particulates to enter the valve  

seat and seize the valve.

D  As soon as fluid stops passing through  
 

the hose, release pressure by shifting the  

SUCTION/DISCHARGE lever to the  

horizontal (SUCTION) position. This must  

be done before opening the inlet ball valve  

or removing tank lid, cleanout door or drain  

plug. The engine will momentarily “SPEED  

UP” and then “SLOW DOWN” and begin to  

“labor”. Once the engine has begun to  

labor, the engine may be switched OFF.  

Open the ball valve and turn OFF the  

gas bottle valve.

The sump cleaner will discharge all but about 
an inch of fluid in the bottom of the compart-
ment. This is unimportant if the compartment 
is used for one type of coolant only. If different 
coolants are involved, remove the compart-
ment’s drain plug to empty it completely.  
Replace drain plug after emptying.
