Blade Guide Adjustment
（
Fig. 9
）
The blade guide assembly consists of two roller guides (bearings) positioned on each side of the
blade to provide blade stability. A third guide (thrust bearing) is positioned behind the blade to
provide blade support. There are two blade guide assemblies – an upper assembly and lower
assembly.
Adjustments are performed in the same manner for each assembly. Follow procedures outlined
below.
Thrust Bearing Adjustment
( Fig. 10 and Fig. 11)
Disconnect machine from the power source! Never make adjustments with the machine running!
Failure to comply may cause serious injury!
Note: Blade must already be tensioned and tracking properly.
1) For the upper thrust bearing, loosen thumbscrew (A). For the lower blade guide, loosen set
screw (B) with the 3mm hex wrench provided.
2) Slide the adjustment shaft (D) so the blade is positioned in the middle of the thrust
bearing (C).
The thrust bearing (C) is mounted on a concentric shaft (D). When the shaft is rotated, the
relative position of the bearing to the back of the blade can be changed.
3) Rotate the adjustment shaft (D) so the thrust bearing (B) just clears the back of the saw
blade.
4) Tighten thumbscrew(A) and setscrew (B). If a blade is being replaced with a new one of a
different size, the adjustment described above may fall out of range and further adjustment
may be required as follows:(Fig. 11)
Loosen the hex cap screw (E, not visible) with a 10mm wrench and adjust the entire assembly
back or forth to just clear the back of the saw blade. Tighten cap screw (E), then fine tune the
adjustment by repeating the first part of this step.
