MAINTENANCE
FLOW METER MAINTENANCE AND ADJUSTMENT (440 SYSTEM ONLY)
1. Remove Flowmeter from Sprayer, brush away any debris and flush with clean water to remove any foreign
material.
2. Remove the retaining rings carefully. Remove the bearing hub, turbine hub, and turbine from inside flowme-
ter.
3. Clean the turbine and hubs of metal filings and any other foreign material. Use pressurized air to blow
metal filings and debris out of both hub and turbine. Check blades for wear. Holding turbine and bearing in
your hand, spin turbine. It should spin freely with very little drag.
4. If bearing hub stud is adjusted or replaced, verify the turbine fit before reassembling. Put turbine hub and
retaining ring in place. Put bearing hub with turbine against turbine hub inside the flowmeter housing. Put
the retaining ring into the groove, to lock bearing hub in place. Spin turbine by blowing on it. Tighten
bearing hub stud until turbine stalls. Loosen the stud 1/3 turn. The turbine should spin freely.
5. Use a low pressure (5PSU) jet of air through flowmeter in the direction of flow and again in opposite
direction to verify that the turbine spins freely. If there is drag, loosen the stud on the bearing hub 1/16 turn
until the turbine spins freely.
6. If turbine spins freely and the cables have been checked, but the flowmeter is not totalizing properly, verify
that the sensor assembly is threaded all the way into the flowmeter body and the orientation groove on top
of the sensor is parallel with the flowmeter body. If flowmeter still does not totalize, replace sensor assem-
bly.
TIRE PRESSURE
Caution must be used when inflating a low tire to recommended pressure. Over inflating can cause tires to ex-
plode. All tires should be 20 psi (1.4bar). Improper inflation will reduce tire life considerably.
WHEEL MOUNTING PROCEDURE
1. Set park brake. Turn machine off and remove key.
2. Block wheel on opposite corner.
3. Loosen nuts slightly on wheel to be removed.
4. Jack up machine being careful not to damage underside of machine.
5. Place wheel on hub lining up bolt holes.
6. Torque to 64-74 ft/lb (87-100Nm) using a cross pattern. Retorque after first 10 hours and every 200 hours
thereafter.
7. Lower machine to ground and remove blocks and jack.
STORAGE
If the machine will be out of service for two or more months, use the following storage procedure.
1. Clean the exterior surfaces of the batteries.
2. Charge Batteries to their full capacity before storing.
3. Remove all chemicals from the spray system.
4. Recharge all batteries when taking out of storage.
5. Store machine in a clean, dry place.
