Operating Instructions
1. Connect to Pressure Washer.
2. 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.
3. Start Pressure Washer. The Hammerhead is ready for operation.
4. Walk slowly behind the Hammerhead cleaning as you go. If
striping occurs, slow down your pace.
5. 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.
6. For maximum effectiveness keep spray tips clean. If the machine
vibrates, stop and clean spray tips.
7. Lubricate swivel with one squirt of good quality grease every 200
hours of operation or about once a month if used daily. A small
amount of grease coming out of the swivel is normal.
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.
