SECTION 2 - SPRAYER OPERATION
C. Prime sprayer mounted gasoline driven pump:
1. Ensure there is liquid available at the pump.
2. Remove or loosen top vent fitting to expel air.
3. If water does not flow from fitting, add fluid until pump casting is full.
4. Verify engine has oil and fuel in it.
5. Turn ignition switch to run.
6. Pull starter rope. Choke engine as required.
7. After start up increase engine speed to circulate water from the tank to the pump and back to the
tank through the agitators.
8. Slow engine to idle and turn ignition switch to off.
D. Prime hydraulically driven pump:
1. Check that oil flow direction is correct by verifying that hose supplying pressure port of pump stiff -
ens when engaging hydraulic lever in the float direction. The pump motor has a check valve on the
tank port that should prevent the pump from running backwards. If the hoses are improperly con-
nected to the tractor the tank hose will get hard and the pump should not run. If your pump runs
both directions contact your Summer’s dealer.
2. Engage tractor hydraulic system and increase to normal field rpm speed in order to circulate water
from tank to pump and back to the tank again through the agitators. Immediately verify agitator
flow by looking through top fillwell .
3. Disengage tractor hydraulic system by moving lever to float position. This allows pump to coast to
a stop.
