HOW TO ADJUST THE BLADE ROTATION CONTROL

WARNING: To prevent an injury, the blade rotation control must operate correctly.

In normal usage, the blade rotation control will not require an adjustment. However, if the cutting performance decreases or the quality of cut is poor, make the following changes.

1.When you mow, make sure the throttle control in in the FAST position.

2.Move the blade rotation control to the DISENGAGE position (Figure 15).

3.Stop the engine. Disconnect the wire from the spark plug.

4.Check the blade(s). Keep a sharp edge on the blade(s). A blade that is not sharp will cause the tips of the grass to become brown.

5.Disconnect the blade drive spring from the blade control rod. Move the blade drive spring to the middle hole (Figure 16). This will increase the tension on the mower drive belt.

6.Attach the wire to the spark plug. Mow for a short distance and again check the quality of cut. If necessary, move the blade drive spring to the bottom hole.

7.Again check the quality of cut. If the quality of cut has not im- proved, replace the mower drive belt. See “How To Replace The Mower Drive Belt”. If replacing the belt does not correct the problem, take the unit to an authorized service center.

8.Move the blade rotation control to the DISENGAGE posi- tion. Stop the engine. Disconnect the wire from the spark plug. Check the operation of the blade brake. Rotate the pulleys with your hand. Make sure the brake pads are pressed tightly against the pulleys (Figure 17).

WARNING: If the brake pads do not press tightly against the pulleys, take the unit to an authorized service center.

9.Move the blade rotation control to the ENGAGE position. Check the pads for the blade brake. If the pads are excessively worn or damaged, replace the brake pad assemblies. Correct replacement parts and assistance are available from an autho- rized service center.

10.Attach the wire to the spark plug. Mow for a short distance and again check the operation of the blade rotation control.

11.When you move the blade rotation control to the DISENGAGE position, all movement will stop within five se- conds. If there is movement of the belt or the blades continue to rotate, engage and disengage the blade rotation control five times to remove any excess rubber from a new mower drive belt. If you need assistance, take the unit to an autho- rized service center.

12.If you replace the mower drive belt, move the blade drive spring to the top hole (Figure 16).
