Operating Instructions
1. Connect inlet filter, D40014 to FSC gun inlet.
2. Connect to Pressure Washer.
3. Turn water on and open valve. Open trigger gun for flow of water through nozzles. Nozzles
must have flowing spray. If not, remove tips and clean; reassemble, making sure that groove of
nozzle is parallel to spray bar. Use thread sealant when installing nozzles.
4. Start Pressure Washer. The Hammerhead is ready for operation.
5. Walk slowly behind the Hammerhead cleaning as you go. If striping occurs, slow down your
pace.
6. Periodically check weep hole on bottom of swivel. Water will seep slowly; if water shoots out,
stop and replace seals. Swivel assembly can be rebuilt.
7. For maximum effectiveness keep spray tips clean. If the machine vibrates, stop and clean spray
tips.
NOTE: Periodically remove the inlet filter, take apart and clean filter screen.
DO NOT ALLOW MACHINE TO REMAIN STATIONARY
ON SOFT SURFACES SUCH AS WOOD.
Caution: Striking any raised obstacle during operation will damage machine. If contact does
occur and results in vibration when operating machine, STOP and replace spray bar. Continued
operation could result in serious injury or damage to machine.
IMPORTANT: TROUBLEHOOTING
If the flat surface cleaner rotating arm is not spinning, tilt the flat surface cleaner up so you can see
the underside of the deck. If a nozzle is not spraying it is plugged and needs to be cleaned. The
best way is to do this is to remove the nozzle (9/16” wrench) and tap it on a hard surface (be care-
ful not to damage the threads). Sometimes it’s necessary to unplug the nozzle by running a thin
wire through the tip.
Seal the threads before replacing the nozzle. Teflon tape can often plug a nozzle so be sure tape
does not get into the nozzle flow path. A light duty liquid or paste thread sealant is the best way to
seal the threads. SEE PHOTO BELOW.
