Check 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 re- quire an adjustment. However, if the cutting perform- ance decreases or the quality of cut is poor, make the following changes.
1.When you mow, make sure the throttle control is in the FAST position (see Figure 8).
2.Move the blade rotation control to the DISEN- GAGE position (see Figure 9).
3.Turn the ignition switch to the OFF positon to stop the engine (see Figure 18).
4.Disconnect the wire from the spark plug.
5.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.
6.If the quality of cut has not improved, replace the mower drive belt. See “Remove and Install the Mower Drive Belt”. If replacing the belt does not correct the problem, take the unit to an authorized service center.
7.When you move the blade rotation control to the DISENGAGE position, all movement will stop within five seconds. If there is movement of the belt or the blades continue to rotate, engage and dis- engage 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 authorized service center.
Check and Adjust the Clutch
If the motion drive belt is loose, the clutch will slip when going up a hill, pulling a heavy load, or the unit will not move forward. Adjust the clutch as follows.
WARNING
Before you make an inspection, adjustment, or repair to the unit, disconnect the wire to the spark plug. Remove the wire from the spark plug to prevent the engine from starting by accident.
1.Check the routing of the motion drive belt. Make sure the belt is installed correctly and is inside all the belt guides.
2.Remove the cotter pin (1) and washer (2) from the adjustable nut (3) (see Figure 22).
