Operating Instructions
1. Bolt the two halves of the handle together with the two M6 x 60mm long bolts, nylok nuts and
four washers.
2. Connect the handle to the brackets on the deck with the two 55mm long pins and rings.
3. Using thread sealant on hose’s male threads, connect the hose to the swivel on the deck.
4. Again, using thread sealant, attach the in-line filter to the inlet of the gun.
5. Connect inlet flter, D40014, to FSC gun inlet.
6. Connect to Pressure Washer.
7. 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.
8. Start Pressure Washer. The Hammerhead is ready for operation.
9. Walk slowly behind the Hammerhead cleaning as you go. If striping occurs, slow down your
pace.
10. 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.
11. For maximum effectiveness keep spray tips clean. If the machine vibrates, stop and clean spray tips.
12.Grease the swivel with one or two grease gun pumps every 200 hours (or once about every 30
days of use). Use No. 2 general purpose waerproof lithium grease. For hot water applications,
use a quality high temperaure grease.
NOTE: NOTE: After 50 hours of use, 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.
STORAGE NOTE
When storing the FSC for a few weeks or months, it is best to drain as much water as possible.
Disconnect the FSC from the pump and stand the handle up. Clamp the gun trigger open and let the water run out. Shop air can also be used at the gun inlet to force out the water.
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 careful 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.
