Finishing Tools Finishing Tools Corner Finisher 2. Place flat box at end of joint. 3. Lead with handle and draw the tool along the joint. 4. Near middle of the joint, remove flat box from joint surface with a sweeping motion. 5. Reverse hand positions and begin again at other end of joint. 1. Press pin on top of corner finisher and install onto valve. 6. Again draw flat box along joint up to previous stopping point and remove box from joint surface with a sweeping motion. 7.
Pressure Relief Procedure 3. Insert cotter pin. 6. Lead with head of taper to make tracking easier. Large trigger feeds material through tool. Small trigger retracts creasing wheel. 7. Roll tape over seam with only one wheel in contact with wall until approximately three inches from end of seam. 8. Stop completely and pull tube back to cut tape. 9. Use drywall knife to detail seams and overlap. 4. Place one hand on control tube and one hand at bottom of mud tub while in use. 5.
Operation Operation Setup GROUNDING INSTRUCTIONS This appliance is rated more than 15 A and is for use on a circuit having a nominal rating of 120 V and is factory equipped with a specific electric cord and plug. No adapter should be used with this appliance. If the appliance must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel; and after the reconnection, the appliance should comply with all local codes and ordinances. 1.
Operation Startup Pump Material NOTICE Do not use with quick-set materials. They can harden inside the unit and hose. 1. Mix material in separate bucket. Gradually add water and mix until desired consistency is achieved. 2. Add mixed material to hopper. 7. Place head of tool over waster bucket and trigger valve until material flows from tool head. Once all water has been flushed from hose and tool, position tool head over hopper until flow rate is determined. 8.
Operation 5. Turn flow control knob fully clockwise until box is filled with material. 6. Turn flow control knob fully counter-clockwise. Fill Taper 1. Install taper-fill adapter. 3. Turn Prime Valve to TOOL FILL position. 4. Turn control knob fully clockwise. 2. Place material inlet of taper over nozzle of taper-fill adapter. 3A0245A 5. Place fingers inside top of taper. When you feel the plunger rise to the top, turn flow control knob fully counter-clockwise.
Operation Bleed System Pressure Install Prime Valve 1. Tighten prime valve into manifold (use thread sealant on housing threads). Torque to 190 to 210 in-lb. 1. Turn flow knob to fully counterclockwise. 2. Place deflector in hopper or suitable container. 2. Install prime valve base. Pin in base must align with hole in manifold. 3. Place prime valve in RELIEF position. 3. Orient .096 in. hole in drain valve stem vertically. Remove Prime Valve 4.
Cleanup Cleanup 2. Hang drain line mount onto material bucket. Turn pump to drain position and pump unused material from hopper and hose. ti11801a NOTICE Do not use with quick-set materials. They can harden inside the unit and hose. ti8794a Storage - Less Than 24 Hours 1. Perform Pressure Relief Procedure, page 6 (valve in down position). 3. Scrape material remaining in hopper into pump to be pumped from sprayer. 2. Remove tool from valve. Clean all tools or use supplied tool caps. ti11760a 3.
Cleanup 7. Remove drain plug from hopper. Flush with water. Clean and install drain plug. 11. Add additional water and repeat steps 13 - 14, if necessary. ti11670a 12. Remove drain plug from hopper. Flush with water. Clean and install drain plug. 13. Rotate pump control to shut pump off. ti11804a NOTE: Cap plug must not be inserted into the female side of the connector on the Z swivel. Residual pressure can cause the cap plug to lose the seal.
Cleanup Troubleshooting Motor Won’t Operate PROBLEM Basic Fluid Pressure Problems Basic Mechanical Problems Basic Electrical Problems CAUSE SOLUTION Pressure control knob setting. Motor will not run if at minimum setting (fully counterclockwise). Slowly increase pressure setting to see if motor starts. Spray tip or fluid filter may be clogged. Relieve pressure and clear clog or clean filter; refer to separate gun or tip instruction manual. Frozen or hardened paint.
Cleanup Motor is Hot and Runs Intermittently PROBLEM Motor is hot and runs intermittently. CAUSE Determine if sprayer was operated at high pressure with small tips, which causes low motor RPM and excessive heat build up SOLUTION Decrease pressure setting or increase tip size. Be sure ambient temperature where Move sprayer to shaded, cooler area if sprayer is located is no more than 90°F possible.
Cleanup Troubleshooting Low or Fluctuating Output PROBLEM Motor runs and pump strokes Motor runs but pump does not stroke CAUSE SOLUTION 1. Material supply. 1. Refill hopper and re-prime pump. 2. Loose fittings. 2. Tighten; use thread sealant or sealing tape on threads if necessary. 3. Intake valve ball and piston ball are seating properly. 3. Remove intake and piston valves and clean. Check balls and seats for nicks or obstructions; replace if necessary, page 18.
Cleanup PROBLEM CAUSE SOLUTION Building circuit breaker opens as soon as sprayer is plugged into outlet and sprayer is NOT turned on. 1. Basic Electrical Problems on page 13. Sprayer quits after sprayer operates for 5 to 10 minutes. 1. Basic Electrical Problems. 1. Perform necessary procedures. 2. Electrical supply with volt meter. Meter must read: 210-255 Vac for 220-240 Vac models; 85-130 Vac for 100-120 Vac models. 2. If voltage is too high, do not operate sprayer until corrected. 16 1.
