Proper flushing of pump after use with herbicides and 
chemicals is essential for long service life. Many herbi-
cides dry quickly and will make pump inoperative if 
allowed to dry inside pump.

Remove pump from tank and insert suction tube into 
water or chemical agent recommended by chemical 
manufacturer.

2.

cal.

For extended storage after use with herbicide or 
chemical, flush pump and fill with diesel fuel.

Before servicing, turn pump off and open the 
nozzle to relieve pressure.

Do not operate pump dry. Do not run pump for more 
than 5 minutes with nozzle closed. Do not operate 
pump for more than 30 minutes continuously in 1 hour.

All fluids pumped must be compatible with wetted 
parts listed on page 12.
