SETUP WARNING If you are supplying your own hoses and spray gun, be sure the hoses are electrically conductive, that the gun has a tip guard, and that each part is rated for at least 2750 psi (190 bar) Maximum Working Pressure. This is to reduce the risk of serious bodily injury caused by static sparking, fluid injection or over-pressurization and rupture of the hose or gun.

OPERATION 4. Cleaning a Clogged Tip WARNING To reduce the risk of serious bodily injury from injection, use extreme caution when cleaning or changing spray tips. If the spray tip clogs while spraying, engage the gun safety latch immediately, then follow the procedure in Steps 4a to 4e, below. NEVER wipe off buildup around the spray tip until pressure is fully relieved and the gun safety latch is engaged.
FLUSHING GUIDELINES NOTE: The Pressure Relief Procedure Warning is on page 14. When To Flush CAUTION NEVER leave water in the sprayer if there is the slightest change it could freeze. Flush out the water with mineral spirits. If water freezes in the pressure control tube, it prevents the sprayer from being started, and causes serious damage to the pressure control. 1. New Sprayer. The sprayer was factory tested in lightweight oil,which was left in to protect the pump parts.
APPLICATION METHODS Always hold the gun perpendicular to the work surface and at an even12 to 14 in. (300–356 mm) from the surface you are spraying. See Fig 9. Begin moving the gun in a horizontal direction at a steady rate. Start the spray stroke off the target surface and pull the trigger as the gun is moving. Then, while the gun is still moving, and as you approach the other edge of the work surface, release the trigger. This method avoids excess paint buildup at the end of each stroke.
TROUBLESHOOTING GUIDE WARNING Pressure Relief Procedure 4. Disengage the gun safety latch. Hold a metal part To reduce the risk of serious bodily injury, including fluid of the gun firmly to the side of a grounded metal pail, and trigger the gun. injection, splashing in the eyes or on the skin, or injury from moving parts, always follow this procedure when 5.

REPLACING THE PRESSURE CONTROL & CIRCUIT BOARD WARNING To reduce the risk of serious bodily injury, including fluid injection or splashing in the eyes or on the skin, or injury from moving parts, always follow the Pressure Relief Procedure Warning on page 14 before checking, adjusting, cleaning or shutting off the sprayer. Unplug the power supply cord. NOTE: A circuit board (23f) is not included with a new pressure control (50). However, it is included with a new motor, and it can be ordered separately.
PRESSURE CONTROL ADJUSTMENT WARNING USE EXTREME CAUTION WHEN PERFORMING THIS ADJUSTMENT PROCEDURE to reduce the risk of a fluid injection injury or other serious bodily injury, which can result from component rupture, electric shock, fire, explosion or moving parts. This procedure sets the sprayer to 2750 psi (190 bar) MAXIMUM WORKING PRESSURE. Perform this procedure whenever the microswitch or pressure control assembly is reinstalled or replaced, to be sure the sprayer is properly calibrated.
PRESSURE CONTROL ADJUSTMENT ON/OFF SWITCH A If the pressure is lower than 2750 psi (190 bar): Unplug the sprayer. Relieve pressure. Insert the wrench and untighten the pressure adjustment nut 1/8 turn or less, then repeat steps 5 and 6. If the pressure is higher than 2750 psi (190 bar): Unplug the sprayer. Relieve pressure. Insert the wrench and tighten the pressure adjustment nut 1/8 turn or less and repeat steps 5 and 6. Repeat this procedure until the proper stall pressure is obtained. 7.
