CIRCUIT BREAKERS
Thermal circuit breakers are located behind the console
access cover at the top of the console. See Figure 56.
Under normal circumstances the circuit breakers do not
require service. They automatically reset 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 (Figure 57, item 2) and
screw bolt in several turns until it no longer makes
contact with the axle.
MAINTENANCE
Figure 56. Circuit Breakers
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.

5. Adjust the left-side stop bolt (item 1) 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 limiting
stop 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.
