REGULAR MAINTENANCE
1. Keep the displacement pump packing nut/wet cup 1/3 full of TSO (Throat Seal Oil) at all times. The TSO
helps protect the packings and rod.
2. Inspect the packing nut daily. Your pump has a patented Triple Life Packing System. Packing life will be
extended a minimum of three times if the following
"Packing Tightening"
procedure is followed:
Inspect the packing nut daily. If seepage of paint into the packing nut and/or movement of
the piston upward is found (while not spraying), the packing nut should be tightened enough
to stop leakage only, but not any tighter. Overtightening will damage the packings and reduce
the packing life.
PATTERN WIDTH
Thickness of the paint coat per stroke is determined by spray
tip "fan width", rate of the spray gun movement, and distance
to surface.
SPRAY TIP REPLACEMENT
During use, especially with latex paint, high pressure will
cause the orifice to grow larger. This destroys the pattern.
Replace tips before they become excessively worn. Worn tips
waste paint, cause overspray, make cutting-in difficult, and
decreases sprayer performance.
Spray tip selection is based on paint viscosity, paint type, and job
needs. For light viscosities (thin paints), use a smaller tip; for
heavier viscosities (thicker paints), use a larger tip size.
Spray tip size is based on how many gallons of paint per minute
can be sprayed through the tip. Do not use a tip larger than the
maximum pump flow rate or capacity the sprayer can accommo-
date. Pump flow rate is measured in gallons per minute (GPM).

Tip Identification: All tips have a 6 digit part number. The first 3 digits identifies it as a Rev-Tip (560) or aFlat
Tip (570). The 4th digit is the fan width - the number is half the fan width, ie. 5 means a 10” fan when it is held
12” from the surface. The 5th and 6th digit is for the orifice size and is measured in thousands of an inch,
ie: 17 = 0.017 inch- the higher the number, the larger the tip.

SPRAY TIP SELECTION
Two tips having the same tip size, but different pattern
widths will deliver the same amount of paint over a different
area (wider or narrower strip).
A spray tip with a narrow pattern width makes it easy to
spray in tight places.
