Stop-Switch Adjustment

CAUTION:

Never attempt to alter, modify or override this switch.

If Stop-switch ever needs to be replaced or adjusted follow the below directions.

1. Loosen Hex Nut.

2. Turn the Linkage Bolt clockwise to lower or

counter-clockwise to raise the point of

interaction with Stop Switch. To set the proper

interaction distance, grip the Operator

Presence Bar & Handle Bar together and

lower the Linkage Bolt onto the Switch Button

until the switch button cannot be depressed

any further. Then raise the linkage bolt one

turn (counterclockwise).

3. Tighten Hex Nut.

4. Verify operability of stop switch before

operating machine by releasing the operator

presence bar next to the handle bar. You

should hear a “CLICK”, signifying that the

Linkage Bolt has been adjusted properly.

Setting Teeth

Among the most critical elements of the stump grinder is the cutting blade. It is also the most

subject to damage and wear. In the course of grinding stumps it not only makes contact with the

wood, but also encounters numerous abrasives and objects in the stump’s environment, such as dirt,

stones, large rocks and buried scrap.

The loss and wear of cutting teeth can significantly impair the efficiency and performance of the

stump grinder. Therefore, it is important to make frequent inspections of the condition of all the

cutting teeth and to sharpen or replace any damaged or worn teeth. Sharpening the teeth before

excessive wear will result in longer lasting teeth and better performance.

Setting Teeth

Installing pockets

1. Locate the straight teeth and pockets on your wheel.

2. Remove one set of straight teeth and pockets.

3. Clean this area with a wire brush.

4. Start with a counterbored pocket. Counterbored pockets have non-threaded big

holes. They go on the right-hand side of the wheel as you face the wheel.
