the idler wheel post as illustrated in Figure 53. (model side shown).

iii. 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 54.
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.
