1.  Before operating this equipment for the first time, 

and periodically thereafter, review the SAFETY 
INFORMATION beginning on page three of  
this manual.

2.  The standard sump cleaner LP gas engine is 

equipped with LIQUID WITHDRAWAL regulators, 
for use with either LIQUID or VAPOR 
WITHDRAWAL LP GAS BOTTLES.

3.  Suction and discharge cycles are controlled by a 

four-way valve in the piping from the SUCTION/
DISCHARGE pump to the tank. Placing the 
valve’s control lever in the horizontal position 
selects the SUCTION mode (FIGURE 1). Moving 
the lever a quarter turn to the vertical position 
selects the DISCHARGE mode (FIGURE 2).

6.  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 Item 7.

7.  To return filtered chip-free coolant to the 

sump, or wash down the machine, or 

discharge dirty coolant into your recycling  

or disposal system,

 close the suction inlet ball 

valve. Move the four-way valve control lever to  
the vertical (DISCHARGE) position. Open the  
gas bottle valve and place choke in “ON” position. 
Turn ignition key to the “START” position while 
moving choke to the “OFF” position. Release key 
when the engine starts and move choke to the 
“OFF” position. Depress the discharge hose 
nozzle valve.
