Circuit Breakers
Thermal circuit breakers are located behind the console access
cover at the top of the console.
Figure 58. Circuit Breakers
Under normal circumstances the circuit breakers do not require
service. They automatically re-set when an overload condition
is corrected. If a breaker is cycling on and off, locate the cause of
the electrical overload and repair as required.
Maximum Cut Depth Adjustment
The saw comes factory-adjusted for maximum usable cut depth.
Should this setting need to be changed, perform the following:
1. With the BLADE REMOVED, park the saw on a flat and
level surface.
2. Fully lower the saw onto the Depth Limiting Stop Bolts.
3. Measure the distance from the Blade Flanges to the surface.
4. If adjustment is required, loosen Locknut on the right-side
Depth Limiting Stop Bolt and screw bolt in several turns
until it no longer makes contact with the axle.

3. Blade Flanges
4. Blade Shaft Housing
5. Adjust the left-side Stop Bolt in or out until the Blade Flange
or Lower Belt Guard achieves 1/8" to 3/16" ground
clearance. Tighten lock nut on left side.
6. Raise saw and place 2 jack stands under the Blade Shaft
Housing.
7. While holding the Raise-Lower Switch in the Lowering
Position, raise the front axle assembly until it contacts the
left-side Depth Limiting Stop Bolt.
8. While holding the axle firmly against the left-side Depth
Limiting Stop Bolt, screw the right-side Depth Stop Limiting
Bolt out until it makes contact with the axle. Tighten lock
nut on right side.
Following this procedure will prevent torsional stresses being
applied to the frame when fully lowered due to uneven adjustment
of Depth Limiting Stop Bolts.

NOTE
While adjustment of the Depth
Stop Limiting Bolts can change the
maximum usable cut depth, they
should not be adjusted to
compensate for unit "wobble" or
blade/cut problems. These
indications are a result of other
issues that should be addressed.
