Maintenance

The surface cleaner does not require maintenance.
Replacing the nozzles: Disconnect the FSC from the pump. Turn the FSC deck upside down and
use a 9/16" combination wrench to unscrew the nozzles. Do not let any debris fall into the open nozzle
ports. Apply thread sealant to the new nozzle threads and thread into the nozzle ports. Tighten
securely making sure the nozzle slot is parallel to the rotating arm.
Replacing the hose: Disconnect the FSC from the pump. Unscrew the hose from the swivel using a
suitable wrench. Thread the hose out of the hose guides on the handle.
Loosen the two socket head cap screws on the gun using a 4mm allen wrench and slide the gun
toward the end of the handle until the gun outlet with the hose is exposed. Disconnect the hose from
the gun.
The new hose can now be attached to the FSC. Use thread sealant on both hose threads and
assemble the hose in the reverse order that it was disassembled.
Replacing the swivel: Disconnect the FSC from the pump then disconnect the hose from the swivel.
Use a 6mm allen wrench to loosen the socket head cap screw on the collar holding the swivel.
