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.
i. Using a 7/64 T-handled hex driver (from Start-Up Kit)
to leverage against the lower idler wheel shaft, push
the idler assembly away from the filament drive gear
by pushing against the spring tension.
When moving the idler wheel assembly, you can obtain
maximum clearance for cleaning if you also move the
Tip Toggle Bar so that it is extended to the same side of
the head assembly as the one on which you are working.
It is not necessary to keep Toggle Bar in a neutral
position.
ii. Insert 1/8 T-handled hex driver (from Start-Up Kit) into
the fixturing hole.
iii. Ease pressure on the 7/64 T-handle driver to carefully
return the leveraged idler wheel back toward its
original position - until the idler assembly is resting
against the 1/8 T-handled hex driver.
iv. Remove the 7/64 T-handled driver used to leverage
the idler assembly.
v. Clean the area that is now accessible. Remove the 1/8
T-handle hex driver when complete.
5. Remove excess material from the top of the liquefier.
• Use needle nose pliers to carefully grip and remove excess
material from the top of the liquefier.
NOTE
NOTE
Liquefier Tubes are fragile. When
removing excess material from the top of
the liquefier be careful not to damage the
tube.
