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

While adjustment of the Depth

Stop Limiting Bolts can change the

maximum usable cut depth, they

NOTEshould not be adjusted to compensate for unit "wobble" or blade/cut problems. These indications are a result of other issues that should be addressed.

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.

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.
