ASSEMBLY
ASSEMBLY CONTINUED
LUBRICATE O-RINGS
LUBRICATING 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.
NOTE: 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 (Fig. 5), 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).
