Setup
Use the following procedures to set up your Transfer Pump.
Converting the Gun to Pressure Feed
Before using the HVLP Transfer Pump, it is necessary to convert your
spray gun from a cup gun to a pressure fed gun.
1. Loosen the retaining nut using a wrench and remove the one
quart cup assembly.
2. Pull the air tube off of the air tube fitting on the spray gun.

Optional: Follow steps 4 and 5 if you have a Maxum II gun
only.
4. Remove the air tube fitting using a 1/4” wrench.

tighten into place.

Mounting the Transfer Pump
1. Make sure both the turbine and Transfer Pump are turned OFF
(0).
2. Locate the small connector cover on the top of the turbine.
Open the cover and slide the Transfer Pump into the turbine
cup holder.
NOTE: The cover should click over the locking tabs and
securely hold the pump in place.

3. Insert the eraser end of a pencil into the inlet valve. This will
free the poppet valve from the valve seat, ensuring the pump
will prime properly.
IMPORTANT: DO NOT perform this step with anything hard
or sharp, such as a screwdriver. The poppet valve could be
damaged.
NOTE: To prevent the poppet valve and seat from sticking,
make sure to follow all Cleanup instructions after
using the pump.
4. Dip the ends of the siphon and return tubes into solvent. This
will make them easier to secure to the Transfer Pump.
5. Insert the suction and return tubes:
a. Press inward on the blue collar and firmly insert the siphon
tube (the larger tube) into the inlet valve fitting.
b. Press inward on the blue collar and firmly insert the return
tube (the smaller tube) into the return tube fitting.
c. Strongly pull on the tubes to make sure the connections are
secure.
