model material
, see

c.
Move idler wheel assembly by pushing with 7/64 inch T-Handle Allen
wrench against spring tension. Insert a 1/8 T-handled Allen wrench (from
startup kit) into the fixture hole. See
Figure 6-384.
Note: Material fed to the tip can sometimes jam causing a build-up of material
under the head cover.
Caution: The end of the tip where the material enters is called the extrusion tube.
Extrusion tubes are fragile. Use care when working in this area so as to avoid
damage to the tubes.
Note: Move only one idler wheel assembly at a time. Finish cleaning around the
moved wheel and restore it to its normal position before moving the other idler
wheel. Having both wheels out of position simultaneously could stretch the
spring.
Position toggle
bar to same
side of head as
T-Handle.
