HIGH PRESSURE  

SWIVEL INFORMATION

The Surface Cleaner Unit high pressure swivel will

“weep” water from underneath the cover. This weeping

is normal for this swivel. The swivel uses water to lu-

bricate its floating seal face to keep wear down to a 

minimum.

Also the high pressure swivel is equipped with a grease

fitting and should be greased at least 

once every three

months

. A good quality ball bearing grease is recom-

mended. 

DO NOT OVER GREASE THE BEARING!

The Warranty for this high pressure swivel is one year

from date of purchase.
