How To Use 

To Assemble

• Step 2: Attach the gasket to the SWIVEL PIPE. Peel off the gasket paper and attach it to the SWIVEL PIPE as shown in the figure in the manual on page 6.
• Step 3: With a flat head screwdriver, use a CLAMP(L) to connect the FLEXIBLE PIPE to the BENT PIPE. Next, using a CLAMP(S), insert the swivel pipe completely into the flexible pipe. Tighten with screwdriver. Then put the band on the seams.
• Step 4: Assemble the STRAIGHT PIPE to the swivel pipe.
• Step 5: Connect the Hose to the Flow Dial and Chemical tank.

• Step 2: Pour chemical into the chemical tank.
• Step 3: Close the lib tightly.
• Step 4: Move the "CHOKE LEVER" fully upward to the closed position. If the engine is already warm, only a partial or open (no choke) choke setting may be required.
