exit the tubes. It is important not to stretch the tarp tight when hanging it. Cleaning tools
can pierce the tarp if it is pulled tight.
HANG THE TARP FASTENED FROM THE TOP ONLY.
DO NOT FASTEN THE BOTTOM EDGE.

DISASSEMBLY OF QS-300
Refer to key numbers on Schematic Diagram for identification of parts.
1.
Remove the air and water pressure lines.
2.
Remove the nozzle connector fitting (P/N 1709 B) and end cap (P/N 1704).
3.
Insert a rod less than 3/8" (9,5 mm) in diameter into the nozzle (P/N 1317) being sure
it is against the piston tube (P/N 1708).
4.
Push the piston and the disc (P/N 1706) out. If they do not come out easily, lubricate
the inside of the unit.
REASSEMBLY OF QS-300
1.
Replace all seals and O-rings.
2.
Lubricate all parts with water resistant grease to facilitate assembly.
3.
Before inserting the piston assembly into the gun body, slide the compression
sleeve over the U-cup seals from the rear of the piston. Make sure the lips of the
U-cups are facing forward, as shown in the Schematic Diagram. The sleeve will slide
off as the piston is inserted into the gun body.
Note:
When reinserting the piston assembly into the gun body, the use of a U-Cup
Compression Sleeve (P/N 1715) is required. FAILURE TO USE THE COMPRESSION
SLEEVE WILL RESULT IN DAMAGE TO THE U-CUP SEALS. Compression sleeves are
available from Goodway Technologies Corporation.
