FLUID OUTLET CIRCUIT BREAKER RESET BUlTON ON/OFF SWITCH PAIL HANGER DISPLACEMENT PUMP PRESSURE RELIEF VALVE MAIN FLUID HOSE WHIP HOBE Your new Ultimate NovaTM 1000 Sprayer functions and operates differently than other airless paint sprayers. This section will help you become familiar with the sprayer before operating it.
Connect Hose and Gun Remove the plastic plug from the pressure control outlet nipple. Connect the main fluid hose to the fluid outlet of the pressure control. See Fig 1. Connect the shorter hose to the main hose and then connect a spray gun to the other end of the hose.
NOTE: -ARNING To reduce the risk of serious bodily injury, including fluid injection, splashing fluid or solvent in the eyes or on the skin, or injury from moving parts or electric shock, always follow this procedure whenever you shut off the sprayer, when checking or servicing any part of the spray system, when installing, cleaning or changing spray tips, and whenever you stop spraying. 1. 2. 3. 4. 5. Engage the gun safety latch. Turn the ON/OFF switch to OFF. Unplug the power supply cord.
SHUTDOWN AND CARE Check the packing nut/wet-cup daily. First follow the Pressure Relief Procedure Warning on page 10. Keep the wet-cup l/3 full of throat seal liquid at all times to help prevent fluid buildup on the piston rod and premature packing wear. The packing nut should be tight enough to stop leakage, but no tighter. Overtightening may cause binding and excessive packing wear. Use a screwdriver and light hammer to adjust the nut. See Fig 5.
When to Flush 1. New Sprayer. Your new Ultimate NovaTM 1000 Sprayer was factory tested in lightweight oil which was left in to protect pump parts. Before using water-base paint, flush with mineral spirits, followed by soapy water, and then a clean water flush. Before using oil-base paint, flush with mineral spirits only. 2. Changing Colors. Flush with a compatible solvent such as mineral spirits or water. to oil-base paint. 3. Changing from water-base Flush with soapy water, then mineral spirits. paint. 4.

CAUTION If check is OK, go to next check When check is not OK refer to this column I I I 1. Check all electrical wiring for damaged insulation, and all terminals for loose fit or damage. Be sure to check wires between pressure control and motor which are encased in conduit (22). See page 29. 1. Repair or replace any damaged wiring or terminals. Securely reconnect all wires.
Before doing this procedure, follow the Pressure Relief Procedure Warning on page 13 to reduce the risk of an injection injury, injury from moving For checking armature, motor winding and brush electrical continuity. setup Remove the drive housing from the sprayer as described in “Drive Housing Replacement”, Steps l-6, page 29. Remove the pressure control cover and screws, the motor cover, the fan cover (FI, and the inspection covers (J). See Fig 7.
BRIDGE WIRES Remove the bridge from the pressure control box and perform this test to determine if the bridge is functional. Use a continuity tester, such as multi-meter set on the Xl ohms scale ( Q 1. Eight individual checks, or tests, must be performed. If the bridge fails even one test, it must be replaced. Fig 9 shows the position of the wires on the bridge. Using the chart at the right, connect the meter wires as indicated by the black dots for each test, then check the continuity.

DRIVE HOUSING REPLACEMENT . I,, (See Fig 22) <;p.::z:,>: ;l,. CAUTION Before doing this procedure, follow the Pressure Relief Procedure Warning on page 13 to reduce the risk of an injection injury, injury from movrng parts or electric shock. Unplug the sprayer1 > NOTE: 1. 2. DO NOT allow the gear cluster (9) to fall when removing the drive housing (2). It is easily damaged if dropped. The gear may stay engaged in either the front end bell or the drive housing.
I. Disconnect the pump outlet hose (47) from the displacement pump outlet nipple (46). 2. Remove the screws (15) and pressure control cover (36) and disconnect the four motor leads. 3. Use an adjustable wrench to loosen the conduit connector nut (345) at the pressure control assembly (43). 4. Swing the conduit (22) away from the conduit connector. 5.
