Adjusting Blade
Guides
These instructions are
hazardous if done while
the machine is connect-
ed to power. Disconnect
power during this entire
procedure!
Guide Blocks
Each guide block consists of an upper and lower
ceramic block that stabilizes the blade from up/
down movement during operation.
The lower block is designed to remain in a fixed
position, and the upper block is designed to be
adjusted during each blade change. When the
machine is new, the lower block is set at the
factory and should not need to be adjusted (see
Section 8: Service Adjustments for more infor-
mation about the lower guide). The upper block,
however, should be adjusted every time you
install a new blade or re-install an old blade.
