9.11 Blade guide adjustment
1. Loosen knobs (A, Figure 24).
2. Slide guide assemblies as close to workpiece
as possible without interfering with cut. This
will prevent excessive blade exposure, and
deflection of blade during cutting.
3. Retighten knobs.
Figure 24
The guide bearings come pre-adjusted from the
factory, but should be inspected frequently and
adjustments made as needed.
For most efficient operation and maximum
accuracy, provide 0.001” clearance between the
blade and the guide bearings. The bearings will still
turn freely with this clearance. If the clearance is
incorrect, the blade may track off the drive wheel.
1. Disconnect machine from power source.
2. Raise bow to vertical and secure in place by
turning off hydraulic cylinder.
3. Loosen socket head cap screw (B, Figure 25)
and adjust guide assembly until back roller
bearing (C) is slightly contacting back edge of
blade.
Figure 25
4. Loosen nut (D) and rotate eccentric shaft (E)
to adjust side bearing until bearing just
touches side of blade. Do not pinch the blade.
5. Blade should still move up and down freely
when grasped as in Figure 26. Make sure
blade teeth do not interfere with guide
bearings.
Make sure power is
disconnected and hands are protected
before handling blade.
6. Tighten nut (D).
7. Repeat for other blade guide assembly.

9.12 Chip brush
The chip brush (B, Figure 19) must be properly
adjusted and maintained in working condition;
otherwise damage to blade can occur. Adjust the
brush so that its bristles overlap the blade.
Replace brush if it becomes worn or damaged.
9.13 On/off switch
The stop screw (A, Figure 27)
must be properly adjusted to prevent damage
to the on/off switch.
Make sure the stop screw (A, Figure 27) is properly
adjusted in conjunction with the shut-off tab (B,
Figure 27). Too much pressure from the shut-off
tab can damage the on/off switch.
