SETTING UP
1. Connect the hose and gun.
a. Remove the plastic cap plug from
the outlet and screw a conductive or
grounded 3000 psi spray hose onto
fluid outlet.
b. Connect an airless spray gun to the
other end of the hose, but do not
install the spray tip yet!
NOTE:
Do not use thread sealer on
swivel unions as they are made to self
seal.
NOTE:
The first 50' of hose should
always be 3/8".
2. Fill the Packing Nut/Wet Cup 1/3 full
with Throat Seal Oil (TSO) supplied.
See Figure 5.
3. Check the engine oil level.
a. Unscrew the oil fill plug. The
dipstick is attached to the plug.
b. Without threading the plug into
place, check to be sure the oil is up
to the top mark on the dipstick.
c. If oil is needed, refer to engine
manual.
4. Fill the fuel tank.
Fuel spilled on a hot
surface can cause a
fire or explosion and cause serious
bodily injury and property damage.
Always shut off engine and let it cool
before filling the tank, and carefully
follow steps a to c below, making sure
you do not spill any fuel.
a. Close the fuel shutoff valve.
b. Use only clean, fresh, well-
known brands of unleaded regular
grade gasoline.
c. Remove the fuel cap and fill
tank. Be sure the air vent in the fill
cap is not plugged so fuel can flow
to the carburetor, then replace the
cap.
SPRAY TIP SELECTION
See Tip Selection Chart on Page 6.
Spray tip selection is based on paint
viscosity, paint type, and job needs. For
light viscosity (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
!
