Inspection and Maintenance:
(continued)
Every 2 Years:
(Approx. 2,000 – 3,000 hours operation time)
Have idler and pull wheel crowned.
NOTE:
An improper or worn crown on the idler and pull wheels will not let the blade track properly
and allows the blade to float in and out. One of the first indications of this is having more blades
requiring tracking or not staying properly tracked between blade changes
.
