Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Installation Installation Grounding To maintain grounding continuity when flushing or relieving pressure: hold metal part of the valve firmly to the side of a grounded metal pail, then trigger the gun/valve. The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current.
Installation 1. Install the pump on the drum cover so that the pump’s fluid intake is 1/2 inch. (13 mm) off the bottom of the drum. (FIG. 2) 2. On Models 204254 and 222087, screw the bung adapter tightly into the drum cover’s bung hole, adjust the position of the pump in the drum, and tighten the bung adapter screw to hold the pump, System Accessories Refer to FIG. 2 for the following instructions.
Operation Operation Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment. 1. Close the pump air regulator and bleed-type master air valve (required in the system). 5.
Troubleshooting Troubleshooting 1. Follow Pressure Relief Procedure, page 6, before checking or repairing gun. 2. Check all possible problems and causes before disassembling gun. Problem Cause Solution Inadequate air supply pressure or restricted air lines Increase air supply and/or clear restriction Closed or clogged valves Open and/or clear Clogged fluid lines, hoses, valves, etc. Relieve pressure.
Service Service Displacement Pump Service 11. Clamp the flats of the fluid piston (110) in a vise, and torque the displacement rod (8) to the piston to 40 to 60 ft-lbs (54 to 81 N.m). 12. Clamp the air motor base (5) in a vise horizontally by closing the vise jaws on the flange. Pump Repair Kit 238286 is available and includes repair parts for the pump and air motor. Use all parts in the kit for best results. 13.
Service 6. Using wrenches on the flats of the displacement rod (8) and on the flats of the fluid piston (110), unscrew the fluid piston from the displacement rod. Remove the ball (111) from the end of the displacement rod, and remove the packing o-ring (104) from the fluid piston. 29 17 11 7. Clamp the air motor upright in the vise by closing the vise jaws below the flange. 24 1 10 8. Unscrew the cylinder cap nut (29) from the top of the air motor cylinder (17). 2 5a 9 21 9.
Service Reassembly 1. Clean all the parts carefully in a compatible solvent, and inspect for wear or damage. Use all the repair kit parts during reassembly, and replace other parts as needed. 2. Check the polished surfaces of the piston (2), displacement rod (8), and cylinder (17) wall for scratches or wear. A scored rod causes premature throat seal wear and leaking. 3. Lubricate all parts with a light, water-resistant grease. 4.
Service 23. Clamp the flats of the fluid piston (11) in a vise, and torque the displacement rod (8) to the piston to 40 to 60 ft-lbs (54 to 81 N.m). 20. Grip the trip rod (11) with padded pliers, screw the cylinder cap (29) onto the trip rod, push the cylinder cap nut down, and screw it into the top of the cylinder. 24. Clamp the air motor base (5) in a vise horizontally by closing the vise jaws on the flange. NOTICE 25.
