Lubricate O-Rings
Lubrication of o-rings is extremely important for
installation and operation. The use of a lubricant
(petroleum or synthetic grease) during assembly helps
seat o-rings properly and provides an improved seal. It
also helps protect the o-ring from damage by abrasion,
pinching or cutting and extends the life of the o-ring.
NOTICE ALWAYS apply a small amount of lubricant
on o-rings prior to assembling the garden hose to the
pump inlet (A), high pressure hose to pump outlet (B),
high pressure hose (C), spray gun (D), and nozzle
extension (E).
Lubricate all connections shown below, following
these instructions:
1. Inspect and clean connecting surfaces prior to
lubrication and assembly.
2. Use lubricants sparingly during assembly; a light
film is all that is required.
3. Use a small brush or cotton swab to apply grease
directly to o-rings where they are not accessible
(QC fitting, M22 fitting).
