manual abstract
. Keep the application area free of debris, including solvent, rags, and gasoline. FLUID INJECTION HAZARD If high-pressure fluid pierces your skin, the injury might look like “just a cut”. But it is a serious wound. Get immediate surgical treatment. To help prevent injection . Keep your hands and body away form the roller frame when flushing. High pressure fluid emitted from the holes in the frame could cause an injection injury. . Always relieve pressure before you check or repair leaks and when you turn off pump or stop painting. . Never use components rated less than system Maximum Working Pressure. ELECTROCUTION HAZARD Failure to observe the electrical hazards described below could result in serious injury, including burns or electrocution. To help prevent harmful electrical shock . Avoid contact with power lines. . Follow all grounding instructions in your separate pump and gun instruction manual, and comply with all local, state, and national fire, electrical, and safety regulations. . Use only MAGNUM or Graco paint hoses. Additional Roller Covers The following MAGNUM pressure roller covers are available at your local distributor: 243063 9 in. (23 cm); 1/2 in.

(32 mm) nap WARNING To help prevent injection injuries, follow this procedure whenever psi/MPa/bar you stop painting. 1. Put gun trigger safety in SAFETY ON position. 2. Shut off power to pump. 3. Turn prime/spray valve to the PRIME position to relieve pressure in system. 4. Put gun trigger safety in SAFETY OFF position, and trigger gun to relieve any pressure in hose. 5. Put gun trigger safety in SAFETY ON position, and keep pump prime/spray valve in PRIME position until you paint again. Operation 1. Follow pump priming instructions using lowest pressure setting at which pump primes. 2. Turn prime/spray valve to SPRAY position. 3. Disengage gun safety latch, trigger the gun, and roll the surface until paint comes to roller. NOTE: Trigger the gun briefly only when you need more paint. Determine how often you must trigger the gun to maintain an even paint supply to the roller. 4. Increase pump pressure only if triggering gun cannot supply enough paint for your rolling speed. See Pressure Relief Procedure on page 2. 5. Whenever you stop painting, relieve the pressure, and elevate roller end of extension tube to prevent paint from draining out. Flush the pump, gun, and pressure roller immediately after each use to prevent paint from drying in the pressure roller and damaging it. See Cleaning on page 2. Cleaning This is the procedure for flushing the pressure roller. The pump and gun you are using may have additional flushing steps, such as cleaning filters and screens. See the pump and gun flushing instructions. 2 309319 NOTE: Leave the pressure roller attached to the gun for this procedure. See Pressure Relief Procedure on page 2. 1. Relieve the pressure. 2.

Place roller frame (1) in paint pail. Be sure the holes in roller frame (1) are facing inside the paint pail. 5. Prime pump with water or flushing fluid for oil–based materials. Use the lowest pump priming pressure setting. 6. Turn prime/spray valve to SPRAY. NOTE: Perform Step 7 at the lowest pressure possible. 7. Trigger gun until flushing fluid begins to dilute the paint. 8. Place roller frame (1) in another bucket and continue flushing until fluid coming out of the roller frame (1) is clear. 9. Shut off the pump. Turn prime/spray valve to PRIME.
