Troubleshooting
If you encounter issues with the sprayer not work-
ing optimally, this section provides a few common
things to check. If these do not correct the issue,
contact your local authorized Walker Dealer.
PUMP LOSES SUCTION
1. Clean the Sump Strainer
2. Check for loose or cracked fittings on the
suction side of the pump.
PUMP CAPACITY DECREASED
1. Clean spray boom’s Tip Strainers and Spray
2. Check that the In-Line Valve (P/N B022, #8) to
boom isn’t partially closed.
3. Verify that the hose isn’t kinked restricting flow.
POOR SPRAY PATTERN
1. Adjust the Spray Tip height.
2. Adjust the Spray Tip direction.
3. Check the Tip Strainers.
PUMP VIBRATES OR SWITCHES ON
AND OFF
Adjust the Allen screw in the top of the pump. Turn
the screw
clockwise
to increase the pump pres-
sure and alleviate the pump turning on and off. This
condition will exist when the spray wand is being
used in the fine mist spray pattern where flow is
restricted. The condition of the pump turning on
and off will not hurt the pump.
Adjust the Pump Pressure
PUMP DOES NOT RUN
1. Check the condition of battery.
2. Check the Wire Harness condition and con-
nections. Inspect the switch.
3. Check the fuse in the Harness Battery Con-
nector.
4. Be sure either the spray wand or the spray
boom valve is open allowing the pump to oper-
ate.
