STARTUP 1. Place the suction tube in the pail of paint. 2. Plug in the sprayer. 3. Open the priming valve 2 turns counterclockwise. 4. Turn the ON/OFF switch ON. 5. You can see the paint being drawn into the suction tube (if the tube is clean). As soon as you see paint flow through the priming tube, close the priming valve. This usually takes less than 30 seconds.
MAINTENANCE CAUTION Thorough flushing and proper maintenance are essential to keep your system working properly 6. Raise the suction tube above the water and run the pump for a few seconds to drain the flushing solution. Shut off the pump. Improper flushing or maintenance may prevent the system from working the next time you need it, and may result in costly damage to the system. 7. Wash off all external parts of the hoses, extension, roller frame, roller valve and pump.
MAINTENANCE Installing and Removing a Roller Cover (See Fig 4) 1. To install a cover, hold the diffuser and unscrew the retainer nut. Slide the cover over the diffuser assembly and reinstall the nut. Do not overtighten the nut. 3. Disassemble if further cleaning is needed. 2. To remove a cover, hold the cover and unscrew the retainer nut. Slide the cover and diffuser assembly off the roller frame. Press on the end of the diffuser assembly to separate it from the cover.
TROUBLESHOOTING GUIDE WARNING Pressure Relief Procedure To reduce the risk of serious bodily injury, including injury from moving parts or electric shock, always follow this procedure whenever you shut off the system, when checking or servicing any part of the system, and whenever you stop painting. 1. Turn the ON/OFF switch to OFF. 2. Unplug the power supply cord. 3. Trigger the roller valve to relieve pressure.
REPAIR Roller Valve WARNING Always follow the Pressure Relief Procedure Warning on page 8 before attempting any repair. NOTE: Order repair kit no. 218–960 to repair this roller valve. 1. Tap out the pin (A) and slide the trigger (B) off of the valve. See Fig 6. N J K D 2. Remove the cap (C).Unscrew the fluid housing (D). See Fig 6. C 3. Pull the needle (K) out. B 4. Tap the seat (G) out of the roller valve (N). See Fig 6. E A F G H 5. Remove the ball (F) and spring (E). See Fig 6. 6.
REPAIR WARNING These repair procedures should be performed only by qualified repair personnel with an electrical back ground, using the proper tools. Failure to do the procedures correctly can result in electric shock, or other serious injury and damage to the pump. WARNING Always follow the Pressure Relief Procedure Warning on page 8 before attempting any repair.
REPAIR Pressure Switch (See Fig 11, 12 & 13) Inlet Valve (See Fig 13) 1. Disconnect the pressure switch leads from the ON/ OFF switch and from the rectifier. See Fig 11. 1. Unscrew the suction hose (44). Unscrew the inlet valve (3). Remove the gasket (4) and replace it if it is worn. 2. Remove the front cover (23). See Fig 13. 2. Screw the new valve into the pump housing, torquing to 27–29 N.m (240–260 in–lb). 3. Unscrew the retainer (14) and remove the pressure switch (12) and o–ring (12a).
REPAIR Diaphragm (See Fig 14) CAUTION To avoid leaks and costly pump damage, replace the diaphragm whenever the pump housing (9) is removed or after each 100 hours of use, whichever comes first. During use, small grooves are formed in the diaphragm which cannot be realigned properly. LUBRICATE THREADS TORQUE TO 85 in-lb (9.6 N.m) 15,16 44 47 45 46 11 17 1. Remove the screws (15). Tip the pump housing (9) back, being careful not to damage the wires. Remove the front cover plate (23). 2.
REPAIR Connecting Rod and Bearing (See Fig 16) 1. Remove the front cover plate (23). Remove the screws (15) and tip the pump housing (9) out of the way. Unscrew the diaphragm (17) and discard. 17 15 PRESS FIT INTO 22 16 30 CAUTION Replace the diaphragm (17) whenever you remove the pump housing (9). During use, small grooves are formed in the diaphragm which cannot be realigned properly. Reusing a diaphragm may cause leaking which will result in costly damage to the pump. 9 69 2.

ACCESSORIES Must be purchased separately. CAUTION To avoid premature wear of the pressure switch, never use more than 7.6 m (25 ft) of 6 mm (1/4 in.) ID outlet hose. When longer outlet hose is needed use 9 mm (3/8 in.) ID hose at a maximum of 30 m (100 ft) long. Never use 6 mm (1/4 in.) ID and 9 mm (3/8 in.) ID hose together. Do not use lacquer or lacquer thinner in the suction and outlet hoses supplied with this system. These fluids quickly destroy the hose material.
