Troubleshooting Troubleshooting Motor Will Not Operate (See flow chart, page 25) PROBLEM Basic fluid flow problems CAUSE Flow control knob turned up but unit is not pumping. SOLUTION Learn the Controller, see page 9. Check battery voltage. Flow control knob setting. Motor will not run if Slowly increase flow setting to see if at minimum setting (fully counterclockwise). motor starts. Basic mechanical problems Basic electrical problems Valve or filter may be clogged. Relieve pressure and clear clog.
Troubleshooting Low or Fluctuating Output PROBLEM Low output CAUSE SOLUTION Pump is worn or clogged. Service pump. Check piston and intake valves for wear or obstructions. Material hose length. Longer hose length reduces drywall feed pump performance. Reduce hose length or thin material. Use 20A setting if available. Pump hopper adapter connections are loose. Tighten any loose connections. Replace pump hopper adapter if cracked or punctured.
Troubleshooting Low or Fluctuating Output (continued) PROBLEM Motor runs and pump strokes CAUSE SOLUTION No material supply. Refill hopper and re-prime pump. Clean hopper strainer. Loose fittings. Tighten; use thread sealant or sealing tape on threads if necessary. Intake valve ball and piston ball are not seating properly. Remove intake and piston valves and clean. Check balls and seats for nicks or obstructions; replace if necessary, page 18.
Troubleshooting RF Problems PROBLEM CAUSE SOLUTION Unwanted signal will not allow unit Unwanted RF signal. Undesired controller is Stop unwanted RF signal by deactivatto learn the controller. active and in close proximity. ing the controller. Use BLOCK feature on Secondary Menu, see page 8. RF controller will not learn. Interference in RF signal 18 Battery is depleted. Replace battery (CR123A Lithium 3V). Unit has not learned the controller. Learn the controller, see page 8.
