Filter
(Periodically)
Check the system air filter/regulator inside the cart tower. Drain the filter and change
the filter element as needed. See Figure 2-11 for the filter location.
Refer to
Parts for the correct filter element. Older units had a white 5 micron particulate
filter element, new units have a yellow 0.3 micron oil/water filter element. The elements
are not interchangeable. If necessary, compare the OEM part number on the side of the
filter/regulator with the OEM part number in the part description to ensure that you order
the correct element.
System
Grounds
Daily: Make sure the system is securely connected to a true earth ground before
spraying powder.
Periodically: Check all system ground connections.
Hopper and
Pickup Tube
(Periodically)
Empty the hopper and clean the interior. Remove and clean the pickup tube. Clean the
fluidizing plate and inspect it for signs of air contamination. If the plate is discolored and
appears to be contaminated, replace it. Check your air supply and correct any
contamination problems.
