Clean the Fluid Tubes
To prevent fluid from drying on the tubes and interfering
with helix rotation, clean the siphon tube (4) and helix
tube (7) when you change colors or coatings and when
the agitator is removed from the drum long enough for
the fluid to dry. Also, clean the fluid tubes for periodic
maintenance as follows:
1.
Remove the bearing nut (8). See F
. 8.
2.
Remove the two diagonal socket-head screws (24)
and lockwashers (25) protruding from the top of the
siphon cover (6).
3.
Remove the siphon tube (4) as follows:
a.
Rest the agitator on its side on the drive belt
housing so the inlet is lower than the outlet. This
orientation prevents fluid from running into the
bearing and drive belt area.
b.
Pull up on the fluid outlet fitting (41) to remove
the siphon tube (4).
4.
Clean the siphon tube (4), helix tube (7), and
bearing nut (8). The inside diameter of the tubes
can be cleaned by pulling a solvent-soaked rag
through them.
NOTE: After you mix or pump catalyzed materials
that could set up between the tubes without air,
always remove the siphon tube, and clean both
tubes.
5.
Apply PTFE spray lubricant to the siphon tube (4)
inlet end only. Install the siphon tube through the top
of the agitator housing (3). Lubricant must have an
auto-ignition rating of 482°F (250°C) or greater.
6.
Install the two socket-head screws (24) and
lockwashers (25) into the top of the siphon cover
(6). Torque the screws oppositely and evenly to 60
to 70 in-lbs (6.8 to 7.9 N•m).
7.
Apply PTFE spray lubricant to the inside lip of the
bearing nut (8), and tighten it onto the helix tube (7).
Torque oppositely and evenly to 60 to 70 in-lbs
(6.8 to 7.9 N•m).
1
2
Torque oppositely and evenly to 80 to 100 in-lbs
(9 to 11.3 N•m).
Apply PTFE spray lubricant to inside lip of bearing nut
before you install it.
3
Apply PTFE spray lubricant to the siphon tube (4) inlet
end before you install it.
