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.

1. Left-Side Stop Bolt

2. Right-Side Stop Bolt

3. Blade Flanges

4. Blade Shaft Housing

Figure 57. Depth Adjustment

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.
